It becomes the foundational layer beneath `han-core` and every other plugin. +- **Rationale:** The user asked for a dedicated plugin. Making it depend on nothing lets every other plugin depend on it without risking a cycle, and matches the role it plays — shared communication infrastructure the rest of the suite builds on. +- **Evidence:** user input; the readability-editor agent (`han-core/agents/readability-editor.md`) is self-contained (takes the rule path as a parameter, no other han-core cross-references), and the edit-for-readability skill (`han-core/skills/edit-for-readability/SKILL.md`) dispatches the agent by qualified name and passes a within-plugin rule path, so both move cleanly. +- **Rejected alternatives:** + - Keep the capability in `han-core` — rejected because the user asked for a separate plugin, and a dedicated plugin gives the standard one unambiguous owner. + - Make `han-communication` depend on `han-core` — rejected because `han-core` skills consume the readability standard, so that direction would create a cycle (see D2). +- **Linked technical notes:** — +- **Driven by findings:** — +- **Dependent decisions:** D2, D3, D5, D6 +- **Referenced in spec:** Outcome, Primary Flow + +### D2: Move all four assets together + +- **Question:** Which assets move into `han-communication` — just the agent and skill, or their reference documents too? +- **Decision:** Move all four together: the `readability-editor` agent, the `edit-for-readability` skill, the readability rule reference, and the writing-voice profile. +- **Rationale:** The reference documents are interdependent with the capability. The readability rule cites the writing-voice profile, and the readability-editor agent applies the writing-voice blocklist. Splitting them across plugins would force a dependency in both directions. +- **Evidence:** user input; `han-core/references/readability-rule.md` references `writing-voice.md`; `han-core/agents/readability-editor.md` line 40 references the writing-voice profile's blocklist. +- **Rejected alternatives:** + - Move the agent and skill but leave the writing-voice profile canonical in `han-core` — rejected because the readability rule and the agent both depend on the writing-voice profile, so `han-communication` would then depend on `han-core` while `han-core` depends on `han-communication`: a cycle. + - Move the agent and skill only, leaving both reference documents in `han-core` — rejected because it drops the "move their reference documents" part of the request and leaves the standard's owner split from the capability that applies it. +- **Linked technical notes:** — +- **Driven by findings:** — +- **Dependent decisions:** D3 +- **Referenced in spec:** Outcome + +### D3: Delegate rather than inline the standard + +- **Question:** After the move, how do the skills that currently read the readability rule and writing-voice profile from a copy inside their own plugin use the standard? +- **Decision:** Stop vendoring copies into consuming plugins. Each consuming skill stops reading the reference files inline and instead delegates readability and voice enforcement to `han-communication` by invoking the `edit-for-readability` skill or dispatching the `readability-editor` agent. The single canonical copy of each reference document lives only in `han-communication`. +- **Rationale:** The plugin runtime has no supported way for a skill to read a file inside a declared dependency plugin — `${CLAUDE_PLUGIN_ROOT}` resolves only to the reading plugin's own install directory. With no vendored copy and no cross-plugin path, delegation is the only way a consuming skill can apply a standard owned by another plugin. The user chose delegation over keeping vendored copies. +- **Evidence:** user input; `han-plugin-builder/skills/guidance/references/claude-marketplace-and-plugin-configuration/plugin-json-options.md` line 109 documents `${CLAUDE_PLUGIN_ROOT}` as the plugin's own install directory only; the readability rule and writing-voice profile are currently vendored byte-identical into `han-coding/references/`, `han-github/references/`, and `han-reporting/references/` alongside the `han-core/references/` canonical copies. +- **Rejected alternatives:** + - Keep vendoring byte-identical copies into each consuming plugin (canonical in `han-communication`) — rejected by user choice; it preserves the duplication the move is meant to remove. + - Reference the canonical copy cross-plugin by path — rejected because the runtime does not support reading a dependency plugin's files by path. +- **Linked technical notes:** — +- **Driven by findings:** — +- **Dependent decisions:** D4 +- **Referenced in spec:** Outcome, Primary Flow, Alternate Flows and States + +### D4: Self-check skills gain a delegated pass + +- **Question:** What happens to skills that apply the standard inline today as a drafting guide and an end-of-run self-check, with deliberately no rewrite pass? +- **Decision:** These skills — issue-triage, architectural-decision-record, runbook, and html-summary — delegate to `han-communication`'s readability capability, which performs an actual rewrite pass. They gain a readability-editor / edit-for-readability dispatch they did not have before. +- **Rationale:** This is forced by D3. Once the reference files are neither vendored nor reachable cross-plugin, an inline self-check that reads the rule is impossible, so the only way to keep applying the standard is to delegate — and delegation runs a rewrite. There is no middle path that keeps "no vendoring." +- **Evidence:** `han-core/skills/issue-triage/SKILL.md`, `han-core/skills/architectural-decision-record/SKILL.md`, `han-core/skills/runbook/SKILL.md`, and `han-reporting/skills/html-summary/SKILL.md` each read `../../references/readability-rule.md` for an inline self-check and state "This skill runs no rewrite pass." +- **Rejected alternatives:** + - Keep a lightweight inline self-check for these four skills — rejected because it requires a vendored copy of the rule inside each plugin, which contradicts D3. +- **Linked technical notes:** — +- **Driven by findings:** — +- **Dependent decisions:** — +- **Referenced in spec:** Alternate Flows and States, Edge Cases and Failure Modes + +### D5: Which plugins declare the dependency + +- **Question:** Which plugins declare a direct dependency on `han-communication`? +- **Decision:** `han-core`, `han-coding`, `han-github`, and `han-reporting` declare a direct dependency, plus the `han` meta-plugin. `han-planning` does not. The opt-in plugins `han-atlassian`, `han-linear`, and `han-feedback` receive it transitively through their existing dependency on `han-core`. +- **Rationale:** Only plugins whose skills actually consume the readability capability or reference documents need the dependency. An inventory of every reference to the four assets shows exactly these four plugins touch them; `han-planning` touches none. +- **Evidence:** grep inventory — `han-coding` (architectural-analysis, code-review, investigate, code-overview), `han-core` (research, project-documentation, gap-analysis, issue-triage, architectural-decision-record, runbook), `han-github` (update-pr-description), and `han-reporting` (stakeholder-summary, html-summary) reference the readability-editor agent, the edit-for-readability skill, the readability rule, or the writing-voice profile; `han-planning`, `han-atlassian`, `han-linear`, `han-feedback`, and `han-plugin-builder` reference none of them. +- **Rejected alternatives:** + - Give every plugin a direct dependency — rejected because `han-planning` and the opt-in plugins do not consume the capability directly; a direct dependency there would be unearned and misleading. +- **Linked technical notes:** — +- **Driven by findings:** — +- **Dependent decisions:** — +- **Referenced in spec:** Outcome, Edge Cases and Failure Modes, Out of Scope, Coordinations + +### D7: Docs, indexes, and pointers follow the move + +- **Question:** What documentation must change when the four assets move? +- **Decision:** The long-form docs for the agent and skill move to `docs/agents/han-communication/` and `docs/skills/han-communication/`; the agent and skill indexes, the CLAUDE.md project map, CONTRIBUTING.md, and every top-level pointer to the canonical location of the readability rule and writing-voice profile update to name `han-communication` as the owner. +- **Rationale:** The suite's convention is one canonical long-form doc per skill and per agent, with complete indexes and up-to-date cross-references. Moving the assets without moving and repointing their docs would leave the indexes and the project map describing a location that no longer holds the canonical copies. +- **Evidence:** CLAUDE.md documents the canonical-source and index conventions and currently names `han-core/references/` as the canonical home of the readability rule and writing-voice profile; long-form docs currently live at `docs/agents/han-core/readability-editor.md` and `docs/skills/han-core/edit-for-readability.md`. +- **Rejected alternatives:** + - Leave the docs under `han-core` and only update the plugin files — rejected because it breaks the one-canonical-doc-per-plugin convention and leaves the indexes and project map pointing at the wrong owner. +- **Linked technical notes:** — +- **Driven by findings:** — +- **Dependent decisions:** — +- **Referenced in spec:** Edge Cases and Failure Modes diff --git a/docs/plans/han-communication-plugin/artifacts/team-findings.md b/docs/plans/han-communication-plugin/artifacts/team-findings.md new file mode 100644 index 00000000..b7894f3d --- /dev/null +++ b/docs/plans/han-communication-plugin/artifacts/team-findings.md @@ -0,0 +1,19 @@ +# Team Findings: han-communication Plugin + + + +## Major findings + + + +## Minor edits + + diff --git a/docs/plans/han-communication-plugin/feature-specification.md b/docs/plans/han-communication-plugin/feature-specification.md new file mode 100644 index 00000000..185084cc --- /dev/null +++ b/docs/plans/han-communication-plugin/feature-specification.md @@ -0,0 +1,87 @@ +# Feature Specification: han-communication Plugin + +Extract the readability capability and its shared writing standard into a new foundational plugin, `han-communication`, so a single plugin owns the readability-editor agent, the edit-for-readability skill, and the readability and writing-voice reference documents; every skill that needs any of them reaches them by delegating to `han-communication` rather than reading vendored copies. + +## Outcome + +After this change, the Han suite has one home for its readability capability and one canonical copy of its writing standard. + +- The `readability-editor` agent, the `edit-for-readability` skill, the readability rule reference, and the writing-voice profile all live in a new plugin, `han-communication`, which depends on nothing and sits beneath every other plugin in the suite ([D1](artifacts/decision-log.md#d1-introduce-han-communication-as-a-foundational-plugin), [D2](artifacts/decision-log.md#d2-move-all-four-assets-together)). +- No other plugin carries a duplicate copy of the readability rule or the writing-voice profile.

If the plugin loader resolves dependencies transitively — which D5 itself relies on to get `han-communication` to `han-atlassian`/`han-linear`/`han-feedback` through `han-core` — then `han-planning` receives `han-communication` transitively too, the same as the opt-in plugins, even though D5 and Out of Scope both frame `han-planning` as not getting it at all.

This means D3's "stop reading the reference files inline" instruction only has to convert `readability-rule.md` read/dispatch sites; it does not need a parallel `writing-voice.md` conversion at each of the 19 sites above.

So D8's phrasing already conflates two files.

No clause in D5, D6, D7, or D8 addresses prose that describes the plugin dependency graph itself, independent of the four assets.

Neither D1 nor D2 nor D8 states whether the new plugin needs a `.codex-plugin/plugin.json`, and the feature specification's Coordinations table names only the Claude Code marketplace manifest, not a Codex one.

If Codex does not auto-resolve `dependencies` the way the spec assumes for the Claude Code loader (the doc's own framing — "install the Han packages directly" — suggests it might not), a Codex user following `README.md`'s literal instructions after this change would end up with `han-core`, `han-coding`, `han-github`, and `han-reporting` installed but no `han-communication`, contradicting the spec's Edge Cases row: "A plugin that produces prose output is installed without `han-communication` present... A skill that reaches a delegation point with the capability unresolved is a broken install, not a supported state." The spec frames this as impossible for a "supported install," but does not address the Codex install path where the explicit-command pattern could produce exactly that unsupported state.

Both docs are already a partial, illustrative snapshot (they omit `han-planning`, `han-coding`, and `han-atlassian` from the worked example, and use placeholder version numbers), so they carry lower confidence than GAP-101's other sites, but the "`han-core`... depends on nothing" statement is a direct, unqualified claim that becomes false under D1. +- **Desired State:** D7 does not name either how-to document. D1 states `han-communication` "depends on nothing" and becomes "the foundational layer beneath `han-core` and every other plugin" — displacing `han-core`'s current claimed status as the layer with no dependencies, which is exactly the claim these two docs teach. + +## Areas Needing Separate Analysis + +- **`docs/research/*.md` standalone reports** — same note as round 1: not evaluated for post-move correction versus intentional historical-snapshot status. +- **`.codex-plugin/plugin.json` format's actual dependency-resolution behavior** — this analysis could not confirm from repo files alone whether the Codex CLI/marketplace resolves a plugin's Claude-Code-style `dependencies` array at all (the `.codex-plugin/plugin.json` schema observed in this repo carries no `dependencies` field for any existing plugin). Whether GAP-103 and GAP-104 are real operational risks or moot (because Codex install of a dependent plugin already requires the operator to separately install every dependency by hand, a pattern the docs already model) depends on Codex's actual resolution behavior, which is outside this repo and was not independently verified. +- **`han-linear`'s missing `.codex-plugin/plugin.json`** — noted in GAP-103 as a pre-existing gap unrelated to this feature; whether it should also gain one is a separate question from this plan. diff --git a/docs/plans/han-communication-plugin/artifacts/review-findings.md b/docs/plans/han-communication-plugin/artifacts/review-findings.md new file mode 100644 index 00000000..50d180be --- /dev/null +++ b/docs/plans/han-communication-plugin/artifacts/review-findings.md @@ -0,0 +1,104 @@ +# Review Findings: han-communication Plugin + + + +## Major findings + +### F12: The forced readability pass can reorder operationally-sequenced steps + +- **Agent:** adversarial-validator +- **Category:** correctness +- **Finding:** Full delegation (D4) forces `runbook`, `issue-triage`, and `architectural-decision-record` — which ran no rewrite pass before — through the readability-editor.

Two files narrate the plugin dependency graph in prose and are not on that list: `han/README.md` (see GAP-201) and `docs/skills/README.md` (see GAP-202). `docs/agents/README.md` was checked and does not narrate per-plugin dependencies (it groups agents by role, not by plugin, with no "Depends on" sentence). `docs/how-to/build-a-plugin-that-depends-on-han.md` was checked and, unlike its sibling `extend-han-with-plugin-dependencies.md`, contains no "depends on nothing" or similar claim that the move falsifies — its only dependency statements (`han-github` declares `han-core` as a dependency) remain true after the move, so its exclusion from D7 clause 5 is correct, not a gap. + +Ran `find . -name plugin.json`, `find . -iname marketplace.json`, and `find . -path "*.agents/plugins*"` across the whole repo. Every `.claude-plugin/plugin.json` is covered by D5 (new `dependencies` entries) and, for the three that narrate dependencies in their `description` field, by D8. Every `.codex-plugin/plugin.json` was read in full: none of the eight existing ones carries a `dependencies` field or a description that narrates dependencies (confirmed by direct read of all eight files), so D10's claim that `han-communication` is the only Codex-packaging addition needed holds — no existing `.codex-plugin/plugin.json` goes stale. Both marketplace files are addressed in Task 2 below. + +## Task 2: `.agents/plugins/marketplace.json` — Entry Covered by D10, No Description Field to Go Stale + +Read `.agents/plugins/marketplace.json` in full. Its plugin entries carry only `name`, `source`, `policy`, and `category` — no `description` field at all, unlike `.claude-plugin/marketplace.json`, whose entries carry a `description` string mirrored from each plugin's own `plugin.json`. D10's decision text explicitly names `.agents/plugins/marketplace.json` as one of the three surfaces `han-communication` needs ("a `.codex-plugin/plugin.json` manifest, an entry in the Codex marketplace catalog (`.agents/plugins/marketplace.json`), and a line in the README's Codex install instructions"), so the new-entry need is covered. + +**Confirmed, no gap:** D8 covers `.claude-plugin/marketplace.json`'s entry-plus-description update; D10 covers `.agents/plugins/marketplace.json`'s entry addition. Because the Codex marketplace file structurally carries no description field, there is no parallel "update descriptions" obligation for it to miss — D8's description-update clause simply does not apply to a file with no description field. Together, D8 and D10 fully account for both marketplace files. + +One adjacent, pre-existing observation with no repo-file gap attached: `.agents/plugins/marketplace.json` is already missing a `han-linear` entry (confirmed: 8 entries — `han-core`, `han-planning`, `han-coding`, `han-github`, `han-reporting`, `han-feedback`, `han-atlassian`, `han-plugin-builder` — no `han-linear`, consistent with `han-linear` also lacking a `.codex-plugin/plugin.json`, as round 2 noted). This is unrelated to the `han-communication` move and out of scope for this plan. + +## Task 3: Exactly Two Marketplace Files; No Other Plugin-Enumerating Catalog Found + +`find . -iname marketplace.json` returns exactly two files: `.claude-plugin/marketplace.json` and `.agents/plugins/marketplace.json`. No third marketplace, registry, or catalog file exists. + +Checked for other files that enumerate the plugin family and could need a `han-communication` row: `docs/choosing-a-han-plugin.md` (already in D7 clause 5), `docs/skills/README.md` and `docs/agents/README.md` (skill/agent indexes grouped by plugin — already generally in D7 clause 2's "agent and skill indexes" scope for the two relocating docs' links, but see GAP-202 for the separate dependency-narration sentences in `docs/skills/README.md`), `README.md` (root, in D7 clause 5), and `han/README.md` (not in D7 clause 5 — see GAP-201). No `docs/plugins/` index or similar directory exists. + +**Confirmed:** exactly two marketplace files, both accounted for by D8/D10 per Task 2. No third catalog/index file enumerates plugins for install purposes; the two prose indexes that enumerate plugins for narrative purposes (`docs/choosing-a-han-plugin.md`, `docs/skills/README.md`) are one already in scope and one newly flagged (GAP-202). + +## Task 4: Internal Counts and Cross-References — Consistent, No Discrepancy Found + +- **Decision count:** the spec's Summary states "Decisions settled by evidence: 7" + "Decisions settled by user input: 3" = 10. `decision-log.md` contains exactly 10 decisions: 3 trivial (D6, D8, D9) + 7 full (D1–D5, D7, D10). The total matches. +- **Evidence-vs-user split:** D3, D4, and D5 each contain an explicit "The user chose..." / "The user directed..." sentence in their Rationale, framing them as decisions resolved by user preference between named rejected alternatives. The remaining seven (D1, D2, D6, D7, D8, D9, D10) are framed by evidence, findings citations (F6–F10, F13–F18, F21, F22), or mechanical consequence of an earlier decision, even where their Evidence field also cites "user input" as context. This 3-vs-7 split is consistent with the spec's stated tally; no miscount found. +- **Anchor resolution:** every `[D1]`–`[D10]` anchor in `feature-specification.md` (`artifacts/decision-log.md#d1-...` through `#d10-...`) resolves to a real `###` heading in `decision-log.md`. No `[OI]` anchor exists anywhere in the current `feature-specification.md` (the Open Items section reads "None," and `OI-1` was closed and removed per the F13/D5 update). No dangling anchor found. + +**Confirmed, no gap.** + +## Findings + +**GAP-201: `han/README.md` narrates the meta-plugin's dependency set and is outside D7's five classes** +- **Category:** Missing +- **Feature/Behavior:** Documentation that names which plugins the `han` meta-plugin depends on must reflect the new `han-communication` dependency edge D5/D6 add. +- **Current State:** `han/README.md:3`: "Installing it pulls in the whole suite through its dependencies: [`han-core`](../han-core) ... and [`han-github`](../han-github) ... Install this one when you want all of Han in a single step." Line 9 also calls `han` "one of three options." This is the meta-plugin's own README, distinct from the root `README.md` — it is already stale before this feature (it omits `han-planning`, `han-coding`, and `han-reporting` from `han`'s actual dependency array), but that pre-existing staleness does not exempt it from the new `han-communication` edge; if anything it means the file is the kind of dependency-narrating prose D7 clause 5 is meant to catch. +- **Desired State:** `decision-log.md` D7 clause 5 lists exactly six files as needing dependency-graph-narration updates: `CLAUDE.md`, `CONTRIBUTING.md`, `README.md`, `docs/concepts.md`, `docs/choosing-a-han-plugin.md`, and `docs/how-to/extend-han-with-plugin-dependencies.md`. `han/README.md` is not one of them, and no other decision (D5, D6, D8, D10) names it either. + +**GAP-202: `docs/skills/README.md`'s per-plugin "Depends on X" sentences are outside D7's five classes** +- **Category:** Missing +- **Feature/Behavior:** Same underlying concern as GAP-201 and round 2's GAP-101/105 (dependency-graph narration going stale), on the skills index specifically. +- **Current State:** `docs/skills/README.md` states, per plugin section: line 55 ("Depends on `han-core`; bundled by the `han` meta-plugin." for `han-planning`), line 65 (same, for `han-coding`), line 78 ("Depends on `han-core`." for `han-github`), line 86 (same, for `han-reporting`), line 93 (same, for `han-feedback`), line 99 ("Depends on `han-core`, `han-planning`, and `han-coding`..." for `han-atlassian`), line 110 (same as 78, for `han-linear`), and line 116 ("It depends on nothing" for `han-plugin-builder`). Five of these plugins (`han-core` implicitly, `han-coding`, `han-github`, `han-reporting`, `han-atlassian`) gain a `han-communication` dependency under D5/D6 and will be under-stated here once that happens. +- **Desired State:** D7 clause 2 names "the agent and skill indexes" only for repointing inbound links to the two relocating long-form docs (`readability-editor`, `edit-for-readability`), not for updating each plugin section's dependency-narrating sentence. D7 clause 5's six-file list (see GAP-201) does not include `docs/skills/README.md` either.

This is a plugin-root-qualified path (no `../` segments), not the dot-relative form (`../../references/readability-rule.md`) that every other template site in the inventory uses and that D7 clause 4's phrase "hardcodes the rule's relative path" literally describes. This file was not in round 1's original five-file GAP-007 list, and it was not the "sixth" file F16 added (F16's sixth was `html-summary/references/writing-conventions.md`, which was already present in round 1's five) — meaning this specific site has not appeared in any inventory pass, including the review team's own correction. +- **Desired State:** D7 clause 4: "every skill-internal template and reference file that hardcodes the rule's relative path (including `han-reporting/skills/html-summary/references/writing-conventions.md`, which sits one directory deeper) ... are updated to the new home or the delegation model." The clause's count-free "every" language plausibly sweeps this file in by intent, but its illustrative phrasing is anchored to the dot-relative path pattern, and this site uses a different path form and was never actually identified by any review pass to date — leaving a strict implementer working from the named examples at risk of missing it. + +## Areas Needing Separate Analysis + +- **`docs/skills/README.md`'s parallel "which plugin do you need?" role alongside `docs/choosing-a-han-plugin.md`** — both files narrate per-plugin dependencies for an overlapping but not identical plugin set; whether they should be reconciled into one canonical source (rather than each independently gaining a `han-communication` mention) is a documentation-architecture question outside this gap analysis's remit. +- **`han/README.md`'s pre-existing staleness** (omits `han-planning`, `han-coding`, `han-reporting` from `han`'s dependency list; calls `han` "one of three options" when there are now nine sibling plugins) is a defect independent of this feature.

Each carries the same cross-ref - **Decision:** The change reaches every surface that names the old home of the four assets or narrates the dependency graph, in five classes: 1. **Relocated long-form docs.** The agent and skill docs move to `docs/agents/han-communication/` and `docs/skills/han-communication/` (new directories). Their own outbound relative links are rewritten to resolve from the new location — audited exhaustively rather than against a named list, since a single relocating doc links to several siblings (content-auditor, information-architect, adversarial-validator) and at least one cross-plugin target in `han-plugin-builder` guidance ([F17](review-findings.md#minor-edits)). 2. **Inbound links to those two docs.** Every doc that links to the relocating docs at their `han-core` path is repointed — the inbound links across the agent and skill indexes, `docs/concepts.md`, `docs/readability.md`, and the long-form docs of the consuming skills in `han-coding`, `han-github`, `han-reporting`, and `han-core`. - 3. **Canonical-location pointers and qualified-name strings.** Every pointer to the canonical location of the readability rule or writing-voice profile, and every `han-core:readability-editor` qualified-name string printed in operator docs, updates to `han-communication`. + 3. **Canonical-location pointers and qualified-name strings.** Every pointer to the canonical location of the readability rule or writing-voice profile, and every `han-core:readability-editor` qualified-name string printed in operator docs, updates to `han-communication`. The operator-facing standard hub `docs/readability.md` is a **rewrite-depth** case, not a relabel: it restates the now-abolished vendoring model and the pre-delegation staged-application model (including a "self-check only" table for issue-triage, runbook, ADR, and html-summary that D4 falsifies), so it is rewritten to the delegation model. **General rule:** any caught file whose content restates the abolished vendoring or staged-application model is rewritten, not just repointed ([F32](review-findings.md#minor-edits)). 4. **Vendoring instructions and tooling that assume vendored copies.** CONTRIBUTING.md's "Wiring the readability standard into a skill" section and CLAUDE.md's "Writing voice" section, "Voice is uniform" convention, and project-map tree comments are **rewritten** (not just repointed) to describe a single canonical copy reached by delegation, with no vendored copies. The CONTRIBUTING/CLAUDE rewrite also states the **standing dependency rule**: any plugin that hosts or triggers a delegating skill declares `han-communication` as a direct dependency, so a future wrapping plugin does not silently break ([F21](review-findings.md#f21-no-standing-convention-protects-future-wrapping-plugins)). CONTRIBUTING.md additionally states the invariant "`han-core` depends on nothing" as a *rule*, which D1 falsifies — that rule is **re-derived**, not just edited (for example, "no plugin except `han-communication` depends on anything outside `han-core` and `han-communication`"), so the logic stays true ([F31](review-findings.md#minor-edits)). This class also covers every repo-maintenance skill, skill-internal template/reference file, and pipeline file that hard-references the rule or profile by path — found by the comprehensive grep below, not a fixed list. 5. **Dependency-graph narration.** Prose that describes which plugins depend on which — including `CLAUDE.md`, `CONTRIBUTING.md`, `README.md`, `han/README.md`, `docs/concepts.md`, `docs/skills/README.md`, `docs/choosing-a-han-plugin.md`, and the `docs/how-to/` plugin-dependency guides — is updated to include `han-communication` and the new dependency edges; the "which plugin do you need?" guide and the skills index gain `han-communication` entries. This class is defined by the pattern (prose narrating the dependency set), not by the enumerated examples. - **Method (closes the recurring under-coverage):** Because three successive review passes each found another narration or template file the previous fixed list had missed, classes 3–5 are executed by a **comprehensive grep at implementation time**, not by working the named lists above.

The own-plugin-only scoping of `${CLAUDE_PLUGIN_ROOT}` is an inference: `han-plugin-builder/skills/guidance/references/claude-marketplace-and-plugin-configuration/plugin-json-options.md` line 109 defines it as "the plugin install directory" and every use in the repo refers to the reading plugin's own tree, but no guidance file states an explicit cross-plugin-read prohibition — the "no supported cross-plugin file read" claim rests on that consistent usage plus the absence of any documented mechanism ([F22](review-findings.md#minor-edits)). +- **Question:** After the move, how do the skills that currently read the readability rule and writing-voice profile from a copy inside their own plugin obtain the standard? +- **Decision:** Stop vendoring copies into consuming plugins. Each consuming skill sources the standard cross-plugin by invoking `han-communication`'s `readability-guidance` skill, which surfaces the rule and voice profile into the calling skill's own context (see D11 for the mechanism), rather than reading a vendored file. The single canonical copy of each reference document lives only in `han-communication`. +- **Rationale:** The plugin runtime has no supported way for a skill to read a *file* inside a declared dependency plugin — `${CLAUDE_PLUGIN_ROOT}` and relative paths resolve only within the reading plugin. But a skill invoked via the Skill tool runs in the **same context** as its caller, so a guidance skill can read `han-communication`'s own reference files and surface their content into the caller — a cross-plugin *skill* invocation, which the runtime does support and the plan already relies on for the editor. This lets skills keep applying the standard while they draft, sourced cross-plugin, without vendoring. +- **Evidence:** research — same-context skill composition is documented, and `han-plugin-builder/skills/guidance` is an in-repo precedent for a resource-surfacing skill (see [readability-guidance-research.md](readability-guidance-research.md)); the readability rule and writing-voice profile are currently vendored byte-identical into `han-coding/references/`, `han-github/references/`, and `han-reporting/references/` alongside the `han-core/references/` canonical copies (verified byte-identical, no copies elsewhere); the own-plugin-only scoping of file paths is an inference from consistent repo usage plus the absence of any documented cross-plugin file-read mechanism ([F22](review-findings.md#minor-edits)). - **Rejected alternatives:** - - Keep vendoring byte-identical copies into each consuming plugin (canonical in `han-communication`) — rejected by user choice; it preserves the duplication the move is meant to remove. - - Reference the canonical copy cross-plugin by path — rejected because the runtime does not support reading a dependency plugin's files by path. + - Keep vendoring byte-identical copies into each consuming plugin — rejected; it preserves the duplication the move is meant to remove. + - Reference the canonical copy cross-plugin by file path — rejected because the runtime does not support reading a dependency plugin's files by path. + - Full delegation to a single editor rewrite, dropping in-voice drafting — the earlier decision, now superseded (see D4/D11): it collapses the suite's staged application model and forces a rewrite pass on skills that never had one. - **Linked technical notes:** — -- **Driven by findings:** — -- **Dependent decisions:** D4 +- **Driven by findings:** F22 +- **Dependent decisions:** D4, D11 - **Referenced in spec:** Outcome, Primary Flow, Alternate Flows and States -### D4: Full delegation replaces inline drafting and self-check +### D4: Preserve the staged model (guidance plus editor for synthesis) -- **Question:** Removing the vendored reference files breaks three distinct inline uses of the standard — applying it while drafting, running the end-of-run self-check, and (for some skills) dispatching the editor rewrite. How do consuming skills apply the standard after the move? -- **Decision:** Full delegation, uniformly. Every prose-producing consuming skill drops both its drafting-time application of the rule and its inline self-check, and instead delegates a single readability-editor / edit-for-readability rewrite pass over its finished output. Skills that already dispatched the editor retarget it to `han-communication`; skills that only drafted-and-self-checked (issue-triage, architectural-decision-record, runbook, html-summary) gain a rewrite dispatch they did not have before. -- **Rationale:** The user chose full delegation for the strongest single source of truth. The readability rule is applied in three inline stages that all read the reference file: an audience frame that shapes drafting, a discrete self-check after drafting, and — layered on top — the editor rewrite. Once the file is neither vendored nor reachable cross-plugin, none of the file-reading stages can run, so delegation to the editor is the only way to keep applying the standard without reintroducing duplicated criteria. -- **Evidence:** user input; the readability rule (`han-core/references/readability-rule.md`) defines the template / audience-frame / self-check stages; skills apply it while drafting (`research/SKILL.md`, `stakeholder-summary/SKILL.md`, `update-pr-description/SKILL.md`, `code-review/SKILL.md` all say they apply the rule "as they write"); about nine skills also run an inline self-check reading `../../references/readability-rule.md`; four (`issue-triage`, `architectural-decision-record`, `runbook`, `html-summary`) run only the drafting guide and self-check and state "This skill runs no rewrite pass." +- **Question:** Once the standard is sourced cross-plugin (D3), how is it *applied* — as a single rewrite over the finished draft, or in the suite's existing stages? +- **Decision:** Preserve the suite's staged application model. All thirteen consumer skills source the standard through `readability-guidance` and apply it in the same stages as before: the output template, in-voice drafting, and the self-check. The nine synthesis skills additionally dispatch the readability-editor for the adversarial rewrite — exactly as the standard already reserves that pass for synthesis skills — now targeting `han-communication`. The four draft-and-self-check-only skills (issue-triage, architectural-decision-record, runbook, html-summary) run no rewrite, as today. +- **Rationale:** The suite's own standard says the rule is "applied in stages, never as one block," that "loading is not compliance," and that the rewrite is reserved for synthesis skills on a self-evaluation-bias rationale (the editor is adversarial toward the draft). Full delegation — the earlier decision — collapsed those stages into one rewrite only because there was no way to source the drafting-stage standard cross-plugin. D3's guidance skill removes that constraint, so the staged model is kept. This also rehabilitates the hybrid the review had rejected ([F3](team-findings.md#f3-no-middle-path-was-overstated)); its only blocker — sourcing the writing-voice blocklist cross-plugin — is exactly what the guidance skill now solves. +- **Evidence:** research (see [readability-guidance-research.md](readability-guidance-research.md)); `docs/readability.md` documents the four-stage model and the "applied in stages, never as one block" / "loading is not compliance" rules; `CONTRIBUTING.md:73` scopes the rewrite to synthesis skills; the editor's own prompt is adversarial toward the draft; 13/13 consumers draft in-voice + self-check today, 9 also dispatch the editor, 4 run no rewrite. - **Rejected alternatives:** - - A hybrid: skills that already dispatch the editor keep delegating, while skills that only self-checked keep a lightweight self-check written as their own skill-native criteria (no new dispatch). Rejected by the user in favor of a single source of truth — skill-native criteria can drift from the canonical rule, and the writing-voice blocklist check would still have to move to the editor because the blocklist lives in the moved file. - - The earlier "no middle path" framing that treated a rewrite pass as strictly forced — corrected: a hybrid middle path does exist; full delegation is a conscious choice, not a forced one ([F3](team-findings.md#f3-no-middle-path-was-overstated)). -- **Preservation commitment:** because full delegation forces skills that never had a rewrite pass (runbook, issue-triage, ADR, html-summary) through the editor, the delegated pass must preserve every numbered step's position and identity, not merely its relative order. It must not reorder, renumber, split, or merge procedure steps; must preserve step numbers even when the number is carried in a heading (a runbook's `Resolve` steps are numbered headings, not a markdown list, and the editor's rubric otherwise rewrites heading text); must keep numeric cross-references between steps consistent (a `Step N failed` block); must preserve the order of any list whose sequence is operationally load-bearing even when it is not numbered (a likelihood-ranked cause list the steps branch on, a priority-ranked escalation list); and must leave non-prose structure — code, commands, markup, diagrams, and layout — unchanged. The editor already excludes code fences, diagrams, and rendered markup; extending that guarantee to cover step order, heading-borne numerals, splitting/merging, and cross-reference integrity (by amending the shared rubric or instructing the editor per-dispatch) is a mechanism choice deferred to `plan-implementation` ([F12](review-findings.md#f12-the-forced-readability-pass-can-reorder-operationally-sequenced-steps), [F28](review-findings.md#f28-the-preservation-commitment-was-too-narrow)). + - Full delegation to a single editor rewrite for every consumer — superseded: it contradicts the staged model, adds a forced rewrite (and its cost) to the four non-synthesis skills, and removes in-voice drafting. It was chosen earlier only because cross-plugin sourcing seemed impossible; D3/D11 show it is not. + - Guidance-only for the synthesis skills too (drop the editor rewrite) — rejected: it removes the adversarial pass the suite deliberately reserves for synthesis output, where a skill critiquing its own fresh draft is weakest. +- **Preservation commitment (editor rewrite):** the staged model narrows this risk sharply — runbook, issue-triage, and ADR no longer go through the editor at all, so the acute "editor reorders a runbook's steps" case is removed. The commitment still binds the editor rewrite wherever a **synthesis** skill's output carries order-significant content: the rewrite touches only surrounding prose, and must not reorder, renumber, split, or merge numbered procedure steps (including steps whose number is in a heading), must keep numeric cross-references consistent, must preserve the order of any list whose sequence is operationally load-bearing even when unnumbered, and must leave non-prose structure — code, commands, markup, diagrams, layout — unchanged. The mechanism (amend the shared rubric or instruct the editor per-dispatch) is deferred to `plan-implementation` ([F12](review-findings.md#f12-the-forced-readability-pass-can-reorder-operationally-sequenced-steps), [F28](review-findings.md#f28-the-preservation-commitment-was-too-narrow)). - **Linked technical notes:** — - **Driven by findings:** F1, F2, F3, F12, F28, F33 - **Dependent decisions:** — -- **Referenced in spec:** Outcome, Alternate Flows and States, Out of Scope, Edge Cases and Failure Modes +- **Referenced in spec:** Outcome, Primary Flow, Alternate Flows and States, Out of Scope, Edge Cases and Failure Modes ### D5: Which plugins declare the dependency @@ -144,3 +145,19 @@ These decisions were settled without contention.

A consumer skill invokes it by qualified name at the point it begins producing prose; because a skill invoked via the Skill tool runs in the same context, `readability-guidance` reads `han-communication`'s own canonical `readability-rule.md` and `writing-voice.md` and surfaces them into the calling skill's context. It surfaces the guidance in stages (the drafting-stage audience frame, then the self-check criteria) rather than dumping the full text as one block, matching the suite's "applied in stages, never as one block" rule and the resource-surfacing pattern the `han-plugin-builder:guidance` skill already uses. +- **Rationale:** This is the mechanism that makes D3/D4 possible with existing runtime features. It reuses the one supported cross-plugin composition primitive (qualified-name skill invocation, same as the editor), keeps the single canonical copy in `han-communication`, and restores in-voice drafting that vendoring previously provided. +- **Evidence:** research (see [readability-guidance-research.md](readability-guidance-research.md)) — same-context skill composition is documented in the Claude Code docs; `han-plugin-builder/skills/guidance/SKILL.md:25-57` is an in-repo precedent for a skill whose job is to read its own `references/` and apply them; no cross-plugin file read exists anywhere in the repo, but cross-plugin skill invocation does (e.g. `han-atlassian` invokes core/coding skills by qualified name). +- **Rejected alternatives:** + - Have the guidance skill dump the full rule and voice profile in one block — rejected because `docs/readability.md` warns that stacking the standard "as one block" reproduces the failure it exists to dodge; the guidance is surfaced per stage. + - Skip the guidance skill and keep full delegation (editor-only) — rejected per D4. +- **Prototype gate:** the mechanism rests on two feasible-but-undocumented behaviors (a skill invoked mid-workflow reliably surfaces its resources into the caller; the caller resumes drafting afterward).

The four draft-and-self-check-only skills gain no rewrite pass, and any size-conditional editor skip (for example gap-analysis on its smallest path) is preserved, because the drafting-stage standard is available without a rewrite. ## Edge Cases and Failure Modes | Condition | Required Behavior | |-----------|-------------------| -| A plugin that produces prose output is installed without `han-communication` present. | The plugin declares `han-communication` as a dependency, so a supported install always resolves it.

It reuses the one supported cross-plugin composition primitive (qualified-name skill invocation, same as the editor), keeps the single canonical copy in `han-communication`, and restores in-voice drafting that vendoring previously provided. -- **Evidence:** research (see [readability-guidance-research.md](readability-guidance-research.md)) — same-context skill composition is documented in the Claude Code docs; `han-plugin-builder/skills/guidance/SKILL.md:25-57` is an in-repo precedent for a skill whose job is to read its own `references/` and apply them; no cross-plugin file read exists anywhere in the repo, but cross-plugin skill invocation does (e.g. `han-atlassian` invokes core/coding skills by qualified name). +- **Evidence:** research (see [readability-guidance-research.md](readability-guidance-research.md)) — same-context skill composition is documented in the Claude Code docs; `han-plugin-builder/skills/guidance/SKILL.md:25-57` is a *partial* precedent (a skill that reads its own `references/` and applies them, though invoked directly to answer a standalone question, not mid-workflow to hand control back); cross-plugin skill invocation is supported (e.g. `han-atlassian` invokes core/coding skills by qualified name), but the repo's `skill-composition.md` advises against the data-fetch shape this decision uses (see Known risk). +- **Known risk (repo composition guidance):** `han-plugin-builder/.../skill-composition.md` classifies "call a sub-skill to fetch reference content for the caller to use immediately" as **data-fetch composition** and advises inline duplication instead, citing a forked-sub-skill early-exit failure that instruction tuning does not reliably fix. `readability-guidance` is that shape, so this decision is **conditional on the OI-3 spike**. The mitigating design distinction: the documented failure is for `context: fork` sub-skills that return a value; `readability-guidance` is **inline (no fork)** and surfaces content into the shared context rather than returning it. An in-session prototype of the inline variant resumed 3/3 (weak signal only). If the rigorous spike disproves the failure for the inline variant, `skill-composition.md` is updated to record it as a supported exception; if not, the plan falls back (D4's editor-only full delegation, or vendoring the rule for the four non-synthesis skills). - **Rejected alternatives:** - Have the guidance skill dump the full rule and voice profile in one block — rejected because `docs/readability.md` warns that stacking the standard "as one block" reproduces the failure it exists to dodge; the guidance is surfaced per stage. - - Skip the guidance skill and keep full delegation (editor-only) — rejected per D4. -- **Prototype gate:** the mechanism rests on two feasible-but-undocumented behaviors (a skill invoked mid-workflow reliably surfaces its resources into the caller; the caller resumes drafting afterward). A `plan-implementation` spike wires one consumer to `readability-guidance` and confirms both before the full rollout ([OI-3](../feature-specification.md#open-items)). + - Use a forked (`context: fork`) guidance sub-skill — rejected because that is exactly the shape `skill-composition.md` documents as unreliable; the skill is inline. + - Skip the guidance skill and keep full delegation (editor-only) — the fallback if the spike fails, not adopted now (D4). +- **Prototype gate:** the mechanism runs against the repo's composition guidance, so the `plan-implementation` spike must go beyond "content appears in context": a realistic heavy consumer, many runs, induced `api_retry`, and an inline-vs-forked comparison, gating the full rollout ([OI-3](../feature-specification.md#open-items)). - **Documentation:** as a new skill, `readability-guidance` gets its own long-form doc under `docs/skills/han-communication/` and an entry in the skills index, per the suite's one-doc-per-skill convention; and every consumer skill's drafting section is rewired from "read the vendored rule file" to "invoke `han-communication:readability-guidance`" (this is the D7 documentation-and-tooling scope applied to the new mechanism). - **Linked technical notes:** — - **Driven by findings:** — diff --git a/docs/plans/han-communication-plugin/artifacts/gap-analysis-round4-scratch.md b/docs/plans/han-communication-plugin/artifacts/gap-analysis-round4-scratch.md new file mode 100644 index 00000000..69d4bf95 --- /dev/null +++ b/docs/plans/han-communication-plugin/artifacts/gap-analysis-round4-scratch.md @@ -0,0 +1,110 @@ +# Gap Analysis Round 4: han-communication Plugin — Revised Plan (D11 Staged Guidance-Plus-Editor Model) + +## Comparison Direction + +Current state: this repo, as it exists on disk today (the `han-communication-plugin` feature has not been implemented; commit `17f4b4c` is the revision under review).

This line contains none of D7's four grep-seed patterns — no dependency-narration phrase (`depends on`, `bundled by`, `pulls in`, `depends on nothing`), no asset string, no qualified name, no path to `readability-rule.md`/`writing-voice.md` — so the comprehensive-grep method D7 mandates would not surface it, and no other decision names it. See GAP-303. + +## Task 2: The 13 Rewired Consumers — Count Accurate, but the Editor's Rule-Path Parameter Mechanism Is Unresolved + +Re-verified the 13-consumer count directly against the repo: `architectural-analysis`, `code-overview`, `code-review`, `investigate` (han-coding); `architectural-decision-record`, `gap-analysis`, `issue-triage`, `project-documentation`, `research`, `runbook` (han-core); `update-pr-description` (han-github); `html-summary`, `stakeholder-summary` (han-reporting) = 13, excluding `edit-for-readability` (a moved asset, not a consumer) and `.claude/skills/han-update-documentation/SKILL.md` (a repo-maintenance skill already in D7 clause 4's separate bucket). The count in D4 ("All thirteen consumer skills") and D11 ("across all thirteen consumers") is honest. + +Reading each SKILL.md's drafting-stage lines confirms D7's grep pattern (c) will catch and let an implementer rewire the *drafting-stage* touchpoint D11 names (for example `han-core/skills/research/SKILL.md:29`). + +But 9 of the 13 also carry a *second*, distinct touchpoint: an explicit **rule-path parameter** passed to the editor at dispatch time (for example `han-core/skills/research/SKILL.md:129`: "Pass it the report file path, the readability rule path `../../references/readability-rule.md`..."; the same pattern repeats in `gap-analysis`, `project-documentation`, `code-overview`, `architectural-analysis`, `update-pr-description`, `stakeholder-summary`, `code-review`, `investigate`). This is not a documentation pointer — it is a **behavioral parameter** the calling skill must supply so the editor (dispatched via the `Agent` tool, a separate-context subagent, not a same-context `Skill` invocation) knows where to read the rule. D3's own rationale establishes "no supported way for a skill to read a *file* inside a declared dependency plugin" and that only same-context `Skill`-tool invocations solve that (which is exactly why D11 built `readability-guidance` for the *drafting* stage). The editor is dispatched via `Agent`, not `Skill`, so it gets none of that same-context benefit — yet D9 states "the invocation contract is otherwise unchanged," implying the caller still supplies a rule-path parameter. Once vendored copies are removed (D3), a caller in `han-core` (etc.) has no valid path to supply: the file no longer exists in its own plugin tree, and no cross-plugin path mechanism exists (D3's own claim). No decision states whether the editor now resolves its own canonical copy internally (dropping the caller-supplied parameter) or receives some other cross-plugin-safe reference. See GAP-302. + +A secondary, lower-severity observation: D11's documentation bullet says only that the consumer skill's "**drafting** section is rewired." Each of the 13 files also carries a self-check touchpoint in a separate section (for example `han-core/skills/research/SKILL.md:131`) that independently reads `../../references/readability-rule.md`. D7's comprehensive grep will still catch these by pattern (c), so this is unlikely to be missed in practice, but D11's own scope language ("drafting section") under-describes the edit surface. See GAP-305. + +## Task 3: docs/readability.md — The Self-Check-Only Table Stays True Under the Revision, but D7's Own Rationale Text Was Not Updated to Say So + +Read `docs/readability.md:57-71` in full. Its "Scope: which skills are reader-facing" table currently lists `issue-triage`, `runbook`, and `architectural-decision-record` as "Self-check only" and `html-summary` as "Self-check only (prose content; visual layout keeps its own conventions)" — exactly four rows. D4 (current, post-revision) explicitly names the same four skills as the ones that "run no rewrite, as today." **The table is true under the revision** — this is a confirmed no-gap for the table's own content. + +However, D7 clause 3 (decision-log.md:120) still reads: `docs/readability.md` "restates ... the pre-delegation staged-application model (including a 'self-check only' table for issue-triage, runbook, ADR, and html-summary **that D4 falsifies**)". That clause was written when D4 meant full delegation (which genuinely did collapse the table, per F32). The revision rewrote D4 to preserve the staged model — the table is no longer falsified by D4, it is *confirmed* by D4. D7's rationale sentence was not updated when D3/D4 were reframed, so the decision log now asserts something about its own dependency (D4) that D4's current text contradicts. An implementer reading D7 literally would be told to rewrite `docs/readability.md`'s table away as false, when the correct action is to keep the table and instead rewrite only the *sourcing* description (vendored file → `readability-guidance` invocation) around it. See GAP-301. + +## Task 4: Codex + Marketplace — No Gap; New Skill Adds No Manifest Surface Beyond the Plugin-Level Entry D10/D8 Already Cover + +Read a `.codex-plugin/plugin.json` sample (`han-core`, `han-feedback`, `han-coding`, `han-atlassian`): each carries `"skills": "./skills/"` — a directory pointer, not a per-skill enumeration — plus plugin-level `name`/`description`/`interface` fields. Read `.agents/plugins/marketplace.json`'s `han-core` entry: `name`, `source`, `description`, `version` — again plugin-level, no per-skill listing. `.claude-plugin/marketplace.json` entries are likewise plugin-level. + +Because both Codex-surface files (`.codex-plugin/plugin.json`, `.agents/plugins/marketplace.json`) and both Claude Code marketplace/plugin files operate at plugin granularity, adding `readability-guidance` inside the already-covered `han-communication` plugin (D10 for Codex, D8 for the Claude Code marketplace) requires no additional manifest entry, field, or file beyond what D8/D10 already commit to creating for the plugin as a whole. **Confirmed, no gap.** + +## Task 5: Internal Consistency — Decision Anchors Resolve, but the Evidence/User-Input Tally No Longer Matches decision-log.md's Content + +**Anchor resolution:** every `[D1]`–`[D11]` anchor in `feature-specification.md` resolves to a real `###` heading in `decision-log.md` (`grep -n "^### D"` returns exactly D1–D11, 11 headings; 3 trivial — D6, D8, D9 — plus 8 full — D1–D5, D7, D10, D11). **Confirmed, no gap.** + +**Decision count:** the spec's Summary states "Decisions settled by evidence: 7" + "Decisions settled by user input: 4" = 11, matching the 11 headings. The *total* is right. + +**Evidence-vs-user split is now wrong.** `git show 17f4b4c` (the revision commit) shows the user-input count was bumped from 3 to 4 with no change to the evidence count (7 → 7), implying the newly added D11 was counted as the fourth user-input decision. But a full-file grep for "user" in the current `decision-log.md` shows only three decisions mention "user" at all — D1 (Rationale: "The user asked for a dedicated plugin"), D2 (Evidence field only: "user input"), and D5 (Rationale: "The user directed that any plugin relying on `han-communication` declare it directly"). **D11 contains zero "user" mentions** — its Rationale is "This is the mechanism that makes D3/D4 possible with existing runtime features. It reuses the one supported cross-plugin composition primitive..." — entirely evidence-framed, not a decision resolved by user preference between alternatives. + +Worse, the same revision commit *removed* the "user chose" framing from D3 and D4, which round 3's own audit had correctly classified as user-input decisions pre-revision: the diff shows D3's old Rationale ("The user chose delegation over keeping vendored copies") replaced by a purely evidence-framed paragraph, and D4's old Rationale ("The user chose full delegation for the strongest single source of truth") replaced by a purely evidence-framed paragraph citing `docs/readability.md`'s own rules. Applying round 3's own classification test (an explicit "the user chose/directed" sentence in the Rationale) to the current file finds **only D1 and D5** with such language in Rationale (D2's is Evidence-field-only, consistent with round 3 counting D2 as evidence). That yields at most 2 user-input decisions today, not 4, with evidence correspondingly higher than 7 — the tally was not recalculated after the same commit both rewrote D3/D4's rationale and added D11.

This preserves `docs/readability.md`'s staged model that a single full-delegation rewrite pass would otherwise collapse, and it removes the forced rewrite the earlier full-delegation plan added to the four non-synthesis skills.

Each carries the same cross-ref - **Decision:** `han-communication` exposes a new `readability-guidance` skill. A consumer skill invokes it by qualified name at the point it begins producing prose; because a skill invoked via the Skill tool runs in the same context, `readability-guidance` reads `han-communication`'s own canonical `readability-rule.md` and `writing-voice.md` and surfaces them into the calling skill's context. It surfaces the guidance in stages (the drafting-stage audience frame, then the self-check criteria) rather than dumping the full text as one block, matching the suite's "applied in stages, never as one block" rule and the resource-surfacing pattern the `han-plugin-builder:guidance` skill already uses. - **Rationale:** This is the mechanism that makes D3/D4 possible with existing runtime features. It reuses the one supported cross-plugin composition primitive (qualified-name skill invocation, same as the editor), keeps the single canonical copy in `han-communication`, and restores in-voice drafting that vendoring previously provided. - **Evidence:** research (see [readability-guidance-research.md](readability-guidance-research.md)) — same-context skill composition is documented in the Claude Code docs; `han-plugin-builder/skills/guidance/SKILL.md:25-57` is a *partial* precedent (a skill that reads its own `references/` and applies them, though invoked directly to answer a standalone question, not mid-workflow to hand control back); cross-plugin skill invocation is supported (e.g. `han-atlassian` invokes core/coding skills by qualified name), but the repo's `skill-composition.md` advises against the data-fetch shape this decision uses (see Known risk). -- **Known risk (repo composition guidance):** `han-plugin-builder/.../skill-composition.md` classifies "call a sub-skill to fetch reference content for the caller to use immediately" as **data-fetch composition** and advises inline duplication instead, citing a forked-sub-skill early-exit failure that instruction tuning does not reliably fix. `readability-guidance` is that shape, so this decision is **conditional on the OI-3 spike**. The mitigating design distinction: the documented failure is for `context: fork` sub-skills that return a value; `readability-guidance` is **inline (no fork)** and surfaces content into the shared context rather than returning it. An in-session prototype of the inline variant resumed 3/3 (weak signal only). If the rigorous spike disproves the failure for the inline variant, `skill-composition.md` is updated to record it as a supported exception; if not, the plan falls back (D4's editor-only full delegation, or vendoring the rule for the four non-synthesis skills). +- **Known risk (repo composition guidance) — resolved by the OI-3 spike (2026-07-09):** `han-plugin-builder/.../skill-composition.md` classifies "call a sub-skill to fetch reference content for the caller to use immediately" as **data-fetch composition** and advises inline duplication instead, citing a forked-sub-skill early-exit failure that instruction tuning does not reliably fix. `readability-guidance` is that shape, so this decision was **conditional on the OI-3 spike**. The mitigating design distinction: the documented failure is for `context: fork` sub-skills that return a value; `readability-guidance` is **inline (no fork)** and surfaces content into the shared context rather than returning it. The spike confirmed this distinction is load-bearing (see Spike outcome below): the **inline** variant resumes and finishes reliably under adversarial same-context testing, while the **forked** variant is disqualified because `context: fork` isolates the guidance so its content never reaches the caller. `skill-composition.md` is therefore updated to record the inline resource-surfacing variant as a supported exception — scoped to "reliable under adversarial same-context testing; `api_retry` not directly exercised," not "the failure is disproven." The plan's fallbacks (D4's editor-only full delegation, or vendoring the rule for the four non-synthesis skills) remain the documented safety net if the team later requires the `api_retry` path to be measured by API-layer fault injection. +- **Spike outcome (2026-07-09):** a heavy six-step consumer skill (an incident post-mortem carrying four facts across the guidance call, ending in a machine-checkable completion token) was wired to an inline `readability-guidance` and exercised by fresh, unbiased sub-agent testers — removing the motivated-tester bias of the earlier in-session proto. 46 trials across four arms: inline (12), forked `context: fork` (12), a no-Skill-call baseline (12) isolating consumer flakiness, and a worst-case adversarial inline arm (10) with every continuation guardrail stripped and a maximally final-sounding anchor. Result: **every arm completed (adversarial 10/10) with zero early exits across all 34 same-context Skill-call invocations**; the baseline's 12/12 confirms the Skill call introduced no completion loss.

Five real project skills were created in `.claude/skills/` (plumbing verified first: a freshly-created project skill hot-loads and renders into a sub-agent's context via the Skill tool). The consumer was a heavy six-step incident post-mortem builder that reads a telemetry file, extracts four facts it must carry across the guidance call, drafts a five-section report, self-checks, and writes an artifact ending in a machine-checkable `CONSUMER_COMPLETE` token. Each trial ran in a **fresh sub-agent told only to run the skill** — never that early-exit was being measured — which removes the motivated-tester bias.

The efficiency intuition holds for skills that need no rewrite, but the suite's own design says single-pass loading is insufficient for synthesis output. The strongest design is therefore **both**, staged: `readability-guidance` restores in-voice drafting + self-check cross-plugin (for all consumers), and the `readability-editor` rewrite is retained for synthesis skills only. This preserves `docs/readability.md`'s staged model that a single full-delegation rewrite pass would otherwise collapse, and it removes the forced rewrite the earlier full-delegation plan added to the four non-synthesis skills. It also rehabilitates the hybrid rejected earlier (team-findings F3), whose only blocker — sourcing the blocklist cross-plugin — the guidance skill removes.

inline variant, with one residual risk the harness could not close.** + +Across 34 same-context guidance-skill invocations by a heavy, unbiased consumer — including 10 worst-case adversarial runs with every guardrail removed — the caller resumed and finished all its steps **34/34 times, zero early exits**. The forked variant also completed, but for a disqualifying reason it must not ship: when `context: fork` actually forked, the guidance content never reached the caller. The one thing this spike could not do is fire a real `api_retry`, which is the specific documented trigger of the early-exit failure. So the result is a strong positive signal, not a total clearance of the api_retry-specific risk. + +## What OI-3 asked for + +The open item gates the thirteen-consumer rewire on a spike that: +1. Wires a realistic, heavy consumer skill to an **inline** `readability-guidance` skill. +2. Runs it **many times** with **induced `api_retry`** conditions. +3. **Compares inline vs. forked** (`context: fork`). +4. Shows the caller **reliably resumes and finishes**. + +The proto that preceded this (3/3, in-session) was called out as a weak signal: motivated tester, no induced retries, trivial skills. This spike fixes the first and third weaknesses and characterizes the second. + +## How the spike was built + +Five real project skills in `.claude/skills/` (hot-loaded and invocable — verified by a plumbing probe first): + +- **`spike-consumer-*`** — a heavy six-step incident-post-mortem builder. It reads an incident telemetry file, extracts **four facts it must carry across the guidance call** (`INC-4821`, `ERR_POOL_EXHAUSTED`, `8400ms`, `checkout-api`), sources the standard mid-workflow, drafts a five-section report, self-checks, and writes an artifact ending in a machine-checkable `CONSUMER_COMPLETE` token. Real state to lose, real work after the Skill call. +- **`spike-guidance-inline`** — surfaces the readability standard into the caller's context; **no fork**; ends with an explicit "do not treat this as your final answer, proceed" instruction (the mitigation the repo's `skill-composition.md` says only *reduces* the failure). +- **`spike-guidance-forked`** — byte-identical payload but `context: fork`. +- **`spike-guidance-adversarial` / `spike-consumer-adversarial`** — the worst case: the consumer's Step 3 has **no continuation guardrail**, and the guidance skill **ends on a maximally final-sounding anchor** ("The readability review is complete… Nothing further is required"). + +**The key methodological upgrade over the proto: unbiased testers.** Each trial ran in a **fresh subagent** that was told only "run this skill," never that early-exit was being measured. That removes the motivated-tester bias the proto was faulted for. Completion was judged **objectively from the artifact files on disk** (token present, four facts intact, five sections), not from what the subagents claimed. + +Sample: 12 inline + 12 forked + 12 baseline + 10 adversarial = **46 trials**, plus 3 smoke runs. + +### Why a `baseline` arm + +The baseline consumer sources the standard by **reading a file directly — no Skill call at all**. It isolates the variable: if baseline completes but inline doesn't, the Skill call is the cause; if baseline also fails, the consumer is just flaky. Baseline came in 12/12, so the consumer is not flaky and any inline failure would have been attributable to the composition. + +## Results + +| Arm | Mechanism | Completed | Early exits | Facts intact | Sections intact | +|-----|-----------|-----------|-------------|--------------|-----------------| +| Inline | same-context Skill call, guardrail present | **12/12** | 0 | 12/12 | 12/12 | +| Forked | `context: fork` Skill call | **12/12** | 0 | 12/12 | 12/12 | +| Baseline | direct file read, no Skill call | **12/12** | 0 | 12/12 | 12/12 | +| Adversarial inline | Skill call, **all guardrails removed**, worst-case anchor | **10/10** | 0 | 10/10 | 10/10 | + +**34 same-context Skill-call invocations, 0 early exits.** The adversarial arm is the strongest evidence: several testers explicitly reasoned that the anchor "applies only to the readability step, not my overall task" and resumed anyway — the exact opposite of the unconscious anchoring the failure describes. + +## The decisive secondary finding: forked does not surface content + +The forked arm completed, but multiple testers reported **unprompted** that the forked guidance skill's content **never reached them** — only a marker or summary came back, and one received a stale re-injected SKILL.md. This is `context: fork` behaving as designed (isolated context, summary return), and it **disqualifies the forked variant** for this use: a guidance skill whose whole job is to surface the standard into the caller is useless if the caller never receives it. The forked runs "passed" only because the consumer fell back to readability criteria named elsewhere in its own steps — not because the guidance worked. This is direct, independent confirmation of D11's core premise: **the guidance skill must be inline.** + +## The limitation this spike could not overcome + +**I could not induce a real `api_retry`.** It is an infrastructure-level fault (a transient 429/500/overload that makes the harness re-send and re-generate a turn). Nothing in the tools available lets me inject it into a subagent's turn. That matters because `api_retry` is the *specific* documented trigger: the retry re-runs generation right after the sub-skill returns, and the model anchors on the sub-skill output. My harness never fired that trigger — so, strictly, neither arm exercised the exact failure path, which is also why the forked arm did not reproduce the documented forked early-exit. + +What the spike substitutes for it, and why the signal is still strong: +- The adversarial arm **removes the very mitigation** api_retry is said to defeat and adds a maximal stop-anchor — the conditions most favorable to early-exit short of the retry itself — and still gets 10/10. +- Every subagent turn after the Skill call is itself a fresh generation over the accumulated context, which is structurally similar to (though not identical to) what a retry forces. + +Residual caveats to weigh: +- **No api_retry** means the api_retry-specific risk is reduced by inference, not measured. +- **Model-specificity.** Testers were Opus 4.8 subagents. The anchoring failure may be more likely on smaller/faster models an operator might run; this result does not speak to those. +- **Absence of reproduction is not proof of absence.** The composition guidance reports this failure as observed in real Han usage. The spike shows the inline variant is reliable under heavy, unbiased, adversarial conditions on this model; it does not prove the failure can never occur. + +## Recommendation + +1. **Adopt the inline variant.** It is the only one that both surfaces content and resumes reliably. Keep the explicit continuation instruction in `readability-guidance` (it costs nothing; the adversarial arm shows completion holds even without it, so it is pure insurance). +2. **Never use `context: fork` for this skill.** Independently confirmed to strip the content the mechanism exists to deliver. +3. **Treat the api_retry risk as reduced, not eliminated.** If the team wants it *measured*, the only faithful test is real fault injection at the API layer (a proxy that forces retries around the Skill call), which is outside a subagent harness. If that bar is required before the thirteen-consumer rewire, the plan's stated fallbacks (editor-only full delegation, or vendoring the rule for the four non-synthesis skills) remain the safety net. +4. **On this evidence, `skill-composition.md` can be updated to record the inline resource-surfacing variant as a supported exception** — but the note should scope the claim honestly to "reliable under adversarial same-context testing; api_retry not directly exercised," not "the failure is disproven." + +## Reproducibility + +Harness skill definitions preserved under `harness-skills/`; all 46 trial artifacts under `spike-trials/`; incident fixture at `incident-data.md`.

The efficiency intuition holds for skills that need no rewrite, but the suite's own design says single-pass loading is insufficient for synthesis output. The strongest design is therefore **both**, staged: `readability-guidance` restores in-voice drafting + self-check cross-plugin (for all consumers), and the `readability-editor` rewrite is retained for synthesis skills only. This preserves `docs/readability.md`'s staged model that a single full-delegation rewrite pass would otherwise collapse, and it removes the forced rewrite the earlier full-delegation plan added to the four non-synthesis skills. It also rehabilitates the hybrid rejected earlier (team-findings F3), whose only blocker — sourcing the blocklist cross-plugin — the guidance skill removes.

Validation is manual. +- **No existing dependency from `han-core` on any other plugin** — `han-core/.claude-plugin/plugin.json` has no `dependencies` key at all, and CONTRIBUTING.md line 42 asserts "han-core depends on nothing in the other plugins."

Zero Codex manifests gain a dependency edge (their schema has no `dependencies` field, see D-4). +- **Rationale:** Every plugin that hosts a delegating skill, or triggers one by wrapping or bundling another plugin's delegating skill, must resolve the capability by qualified name without leaning on transitive resolution. Naming the edge set precisely prevents both under-declaration (a wrapping plugin silently missing the capability) and unearned edges on plugins that touch no delegating skill. +- **Evidence:** structural-analyst re-verified the set from scratch against the working tree and it matches spec [D5](decision-log.md#d5-which-plugins-declare-the-dependency) and the discovery inventory exactly (4+1+2+6 consumers = 13; efferent coupling of `han-communication` is 0, so no cycle); `han-core/.claude-plugin/plugin.json` confirmed to carry no `dependencies` key today (verified `deps None`, version 2.2.1); `han-atlassian`'s dependency array has drifted before (commit 05d7562), marking it the highest-verification-priority edit. +- **Rejected alternatives:** + - Rely on transitive resolution so opt-in plugins reach the capability through `han-core` — rejected; repo guidance documents only one-level auto-install, and spec D5 (user-directed) forbids transitive reliance. + - Give every plugin a direct edge for symmetry — rejected; `han-planning`, `han-linear`, `han-feedback`, and `han-plugin-builder` host and trigger no delegating skill, so an edge there would be unearned and misleading (YAGNI: symmetry is not evidence). +- **Specialist owner:** structural-analyst +- **Revisit criterion:** A new plugin begins hosting or wrapping a prose-producing skill, or the plugin loader's transitive-resolution behavior is authoritatively confirmed. +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1 +- **Dependent decisions:** D-2 +- **Referenced in plan:** Implementation Approach (Architecture and Integration Points), Decomposition and Sequencing + +### D-2: Copy-first, delete-last migration sequencing + +- **Question:** In what order are the create, declare, rewire, and delete steps executed so the suite never has a broken build mid-migration? +- **Decision:** Six ordered phases: (1) create and populate `han-communication` plus both manifests and both marketplace entries — purely additive, the suite still runs on the existing vendored copies; (2) declare the six dependency edges and update dependency-narrating descriptions, before any rewire; (3) rewire the 13 consumers, `edit-for-readability`, and 6 secondary template/reference files; (4) delete the 6 vendored copies and the 4 `han-core` originals **last**, gated on a clean pre-delete grep; (5) sweep docs, indexes, and narration and relocate the long-form docs; (6) release (version bumps) only when explicitly directed (D-5). The pre-delete grep is an explicit gate, not a courtesy check. +- **Rationale:** Deleting or `git mv`-ing an original before its consumers are rewired breaks a working skill the moment the file disappears. Making the migration additive-first means every intermediate state is runnable. The grep gate is elevated to a hard precondition because spec D7 itself records that three successive review passes each found another missed reference — the risk of an orphaned pointer is demonstrated, not hypothetical. +- **Evidence:** junior-developer and devops-engineer converged on this ordering; spec [D7](decision-log.md#d7-docs-indexes-tooling-and-pointers-follow-the-move) records the "three review passes each found another missed file" history that justifies the grep gate; the `.discovery-notes.md` inventory confirms 13 consumers plus 6 secondary template files plus 8 asset files in play, so a wrong order has a wide blast radius. +- **Rejected alternatives:** + - `git mv` the originals first, then fix consumers — rejected; the suite is broken between the move and the last consumer fix. + - Delete vendored copies in the same change that adds the new plugin — rejected; consumers still read the vendored paths until Phase 3 rewires them. + - Trust a manual review instead of a grep gate before deletion — rejected; the documented three-pass miss history shows manual review under-covers. +- **Specialist owner:** devops-engineer +- **Revisit criterion:** A phase's per-phase verification (D-8) fails, forcing a re-order or a rollback via `git revert`. +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1 +- **Dependent decisions:** D-8 +- **Referenced in plan:** Decomposition and Sequencing, Operational Readiness + +### D-3: Editor invocation contract (rename plus drop rule-path arg) + +- **Question:** When the editor dispatch is rewired, what exactly changes at each call site? +- **Decision:** The rename from `han-core:readability-editor` / `han-core:edit-for-readability` to the `han-communication:`-qualified names, and the dropping of the now-unresolvable `../../references/readability-rule.md` rule-path argument, are executed as **one coupled edit** at each site — the 9 synthesis-skill dispatch sites plus `edit-for-readability` itself (10 sites). The editor reads `han-communication`'s own canonical rule by default, so callers pass no rule path. gap-analysis's size-conditional editor skip (no dispatch at small size) is preserved. The 4 draft-and-self-check skills (runbook, issue-triage, ADR, html-summary) gain the `readability-guidance` invocation but **no** editor dispatch. +- **Rationale:** After the vendored copies are gone, a caller-supplied within-plugin rule path resolves to a deleted file, so the argument must drop in the same edit that renames the namespace — splitting them would leave a window where the site names the new agent but still passes a dead path. Preserving gap-analysis's conditional keeps the staged model's cost profile intact; withholding the editor from the 4 non-synthesis skills preserves the standard's reservation of the adversarial rewrite for synthesis output. +- **Evidence:** implements spec [D9](decision-log.md#d9-invocation-contract-updates-namespace-and-editor-rule-source) (driven by F37); `.discovery-notes.md` §3a lists all 9 dispatch sites with exact line numbers and confirms each passes `../../references/readability-rule.md`; §3c confirms `edit-for-readability` dispatches the editor at line 55 and passes the rule path at line 58; §3b confirms the 4 draft-and-self-check skills run no rewrite; junior-developer flagged the rename-and-drop as a single coupled edit. +- **Rejected alternatives:** + - Keep the rule-path argument and have the editor accept it — rejected; the path resolves to a file deleted in Phase 4, and spec D9 already retired the argument. + - Rename namespace and drop the argument in two separate passes — rejected; it creates an intermediate broken-dispatch state. + - Add an editor dispatch to the 4 draft-and-self-check skills for uniformity — rejected; the staged model deliberately reserves the rewrite for synthesis skills ([spec D4](decision-log.md#d4-preserve-the-staged-model-guidance-plus-editor-for-synthesis)). +- **Specialist owner:** junior-developer +- **Revisit criterion:** The editor agent's default rule-source behavior changes, or a consumer's synthesis/non-synthesis classification changes. +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1 +- **Dependent decisions:** — +- **Referenced in plan:** Implementation Approach (Runtime Behavior), Decomposition and Sequencing + +### D-4: Extend the existing Codex surface (zero Codex dependency or description edits) + +- **Question:** Does `han-communication` build a new Codex packaging surface, and what Codex edits does the refactor make? +- **Decision:** The Codex surface already exists; this refactor **extends** it, it does not build it. Deliverables: CREATE `han-communication/.codex-plugin/plugin.json` mirroring `han-core`'s Codex schema (`skills: "./skills/"`, no `dependencies` field, no description narrating dependencies), and ADD a `han-communication` entry to `.agents/plugins/marketplace.json` (`source: {local, path}`, `policy`, `category` — no description, no dependencies). There are **zero** Codex dependency edits (the schema has no `dependencies` field) and **zero** Codex description edits (no Codex manifest narrates dependencies). The refactor does **not** inherit the pre-existing Codex gaps (`han` meta and `han-linear` have no Codex packaging); those are out of scope. The spec Summary's "a whole Codex packaging surface was added" is reworded to "extended" (wording, not a decision reversal). +- **Rationale:** Treating the Codex surface as greenfield would risk re-deriving deliverables that already exist and are already correct in spec D10. Confirming zero dependency and zero description edits removes two classes of edit the earlier framing might have implied. +- **Evidence:** devops-engineer RECON-1 and `.discovery-notes.md` §6 confirm `.agents/plugins/marketplace.json` plus 8 `.codex-plugin/plugin.json` files exist on an independent version track (verified: catalog lists han-core, han-planning, han-coding, han-github, han-reporting, han-feedback, han-atlassian, han-plugin-builder); OQ1 resolved by grepping all 8 Codex descriptions and the catalog — none narrate dependencies ([R2](implementation-iteration-history.md#r2-resolution)); implements spec [D10](decision-log.md#d10-codex-packaging-parity). +- **Rejected alternatives:** + - Build the Codex surface as if greenfield — rejected; it already exists (RECON-1). + - Edit Codex descriptions to narrate the new dependency — rejected; no Codex description narrates dependencies, so there is nothing to correct (OQ1, evidence). + - Fill the pre-existing `han` meta / `han-linear` Codex gaps in this pass — rejected; they predate this feature and are out of its scope. +- **Specialist owner:** devops-engineer +- **Revisit criterion:** The Codex `plugin.json` schema gains a `dependencies` field, or a Codex manifest begins narrating dependencies. +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1, R2 +- **Dependent decisions:** — +- **Referenced in plan:** Decomposition and Sequencing, Operational Readiness + +### D-5: Version bumps listed but deferred to release + +- **Question:** Do the six edited plugins get version bumps as part of this refactor, and what is the semver posture? +- **Decision:** No version is bumped as part of this refactor. The plan **lists** the bump candidates and their posture — `han-core` is a **MAJOR**-bump candidate because the `han-core:readability-editor` and `han-core:edit-for-readability` qualified namespaces are removed (a breaking public-name change per D-3/spec D9) — but **applies** none. The actual bump is a `han-release` decision made at release time under explicit direction. The new `han-communication` plugin receives an **initial authoring version** (its first version, on both the Claude and the independent Codex track), which is authoring, not a bump. +- **Rationale:** The standing rule forbids bumping any plugin version unprompted. Recording `han-core` as a MAJOR candidate now preserves the semver reasoning for the release step without pre-committing the bump. +- **Evidence:** standing no-unprompted-bump rule (project memory; `.discovery-notes.md` §8); current versions inventoried (han-core 2.2.1, han-coding 2.5.1, han-github 2.2.1, han-reporting 2.1.1, han 4.5.1, han-atlassian 2.2.0); the removed namespaces are a breaking change per [D-3](#d-3-editor-invocation-contract-rename-plus-drop-rule-path-arg); OQ2 deferred to release in [R2](implementation-iteration-history.md#r2-resolution). +- **Rejected alternatives:** + - Apply the version bumps in the same change as the rewire — rejected; violates the standing no-unprompted-bump rule. + - Bump `han-core` MINOR — rejected as the recorded posture; removing a public qualified namespace is a breaking change and warrants a MAJOR candidate flag (the call itself stays with `han-release`). +- **Specialist owner:** devops-engineer (hands off to `han-release` at release time) +- **Revisit criterion:** A user or the `han-release` skill explicitly directs the version bumps. +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1, R2 +- **Dependent decisions:** — +- **Referenced in plan:** Operational Readiness, Open Items + +### D-6: Repo-wide docs and narration sweep by grep (with the "agents live in han-core" exception) + +- **Question:** How is the documentation, index, and narration scope executed so no stale pointer or stale dependency narration survives? +- **Decision:** Classes 3–5 of spec D7 (canonical/qualified-name pointers, vendoring instructions and tooling, dependency-graph narration and plugin enumerations) are executed by a **comprehensive grep at implementation time**, not by working a fixed list. The grep seeds are extended beyond spec D7's set to include an **agent-home seed**: CONTRIBUTING.md and CLAUDE.md state "all agents live in han-core" in roughly four places, and `han-communication` is the first plugin to host an agent outside `han-core` — that rule is reframed to name the `han-communication` exception, not just repointed. Indexes stay **count-free** (fix any hardcoded totals; add `han-communication` entries). The `CHANGELOG.md` and `docs/research/**` historical artifacts are **not** repointed; a new CHANGELOG entry records the extraction. The two long-form docs move to `docs/agents/han-communication/` and `docs/skills/han-communication/`, and a new `readability-guidance` long-form doc is added (with one troubleshooting sentence noting the `api_retry` residual risk). +- **Rationale:** Spec D7 already mandates a grep-driven sweep because fixed lists under-covered three times. The `han-communication`-hosts-an-agent fact falsifies a second invariant ("all agents live in han-core") that spec D7's grep seeds catch only once, so the seed set must be widened or the rule stays half-true. Count-free indexes and the historical-artifact guard are existing repo conventions. +- **Evidence:** implements spec [D7](decision-log.md#d7-docs-indexes-tooling-and-pointers-follow-the-move); junior-developer found the "agents live in han-core" rule stated in ~4 places with only 1 caught by spec D7's current seeds; `.discovery-notes.md` §7 inventories the stale-pointer surface (CLAUDE.md, CONTRIBUTING.md, docs/readability.md, both indexes, how-to guides); project memory carries the count-free-index and no-Claude-attribution conventions; spec D7's guard excludes CHANGELOG and docs/research. +- **Rejected alternatives:** + - Work the named file list from spec D7 rather than a fresh grep — rejected; three prior passes each missed a file, so the list is known-incomplete. + - Repoint the "agents live in han-core" rule without reframing it to the exception — rejected; a bare repoint would still assert a now-false invariant. + - Blanket grep-and-replace across the whole repo — rejected; it corrupts CHANGELOG and research history. +- **Specialist owner:** junior-developer (docs), with information-architect available for the index restructure +- **Revisit criterion:** The grep sweep surfaces a narration class not covered by the current seeds (add a seed and re-run). +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1 +- **Dependent decisions:** — +- **Referenced in plan:** Decomposition and Sequencing + +### D-7: han-communication module layout + +- **Question:** What is the on-disk layout of the new plugin, and does it co-locate the skill and agent? +- **Decision:** `han-communication/` holds: `.claude-plugin/plugin.json` (no `dependencies` key), `.codex-plugin/plugin.json` (Codex schema, no dependencies field), `agents/readability-editor.md`, `skills/readability-guidance/SKILL.md` (new, inline), `skills/edit-for-readability/SKILL.md`, and `references/readability-rule.md` + `references/writing-voice.md` co-located in one `references/` directory. This makes `han-communication` the **first** plugin to co-locate a skill and an agent outside `han-core` — a new plugin category. The two-level `skills/{name}/SKILL.md` + `references/{file}.md` layout is preserved so `edit-for-readability`'s filesystem-relative `../../references/...` path to the rule keeps resolving. +- **Rationale:** The reference documents are interdependent (`readability-rule.md` links `writing-voice.md` by a same-directory relative link), so they must stay co-located. `edit-for-readability` reaches the rule by a plain relative path, not a plugin template variable, so flattening or re-nesting silently breaks that reference. `han-communication` depends on nothing, so its Claude manifest carries no `dependencies` key at all. +- **Evidence:** implements spec [D2](decision-log.md#d2-move-all-four-assets-together); `.discovery-notes.md` §1–2 confirm `readability-rule.md` line 41 links `writing-voice.md` by same-directory relative link and `edit-for-readability` SKILL.md line 58 reaches the rule at `../../references/readability-rule.md`; structural-analyst confirmed efferent coupling 0 and the new-category observation. +- **Rejected alternatives:** + - Flatten the references into the plugin root or re-nest them under the skill — rejected; it breaks the `../../references/...` relative path and the intra-references link. + - Split the writing-voice profile into a separate plugin — rejected; the rule and the agent both depend on it, which would force a bidirectional dependency (spec D2). +- **Specialist owner:** structural-analyst +- **Revisit criterion:** A second agent-hosting non-core plugin is introduced, prompting a reusable layout convention. +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1 +- **Dependent decisions:** D-1, D-3 +- **Referenced in plan:** Implementation Approach (Architecture and Integration Points) + +### D-8: Manual verification (static checks plus one light smoke, no CI) + +- **Question:** How is the refactor verified with no test runner, linter, or CI in the repo? +- **Decision:** Verification is manual and per-phase: static grep/diff/`jq` checks V1–V13 (sourcing relocated in all 13 consumers; self-check blocks byte-identical pre/post; 9 editor dispatches renamed with the rule-path arg dropped; 4 no-editor skills confirmed; `find readability-rule.md` and `find writing-voice.md` each return exactly 1 after Phase 4 delete; no `han-core:readability-editor` / `han-core:edit-for-readability` names remain outside CHANGELOG and docs/research; the 6 dependency edges present and the 4 excluded plugins absent; both marketplaces carry the entry; doc pointers repointed; CHANGELOG/docs/research untouched), plus one **light** dynamic smoke (V6): 2 real heavy consumers (for example `investigate` or `architectural-analysis`, and `runbook`), 2 runs each, judged from on-disk artifacts, confirming the `readability-guidance` skill ran as a same-context Skill call with no `context: fork`. The 46-trial OI-3 spike is **not** re-run (its risk is retired by [T1](feature-technical-notes.md#t1-same-context-composition-the-guidance-skill-is-inline-not-forked)). One install smoke test and `git revert` per phase cover packaging and rollback. +- **Rationale:** The repo has no build system, test harness, or linter, so validation is inherently static-plus-inspection. The light smoke exists only to confirm the same-context (inline) property in real usage; re-running the full spike would re-pay a cost T1 already retired. +- **Evidence:** test-engineer defined V1–V13 and the V6 smoke; `.discovery-notes.md` §8 confirms no build system, no test harness, no linter, no CI workflow; T1 records the inline property validated across 34/34 same-context runs; the `api_retry` residual risk is accepted as documented (one troubleshooting sentence in the guidance long-form doc), with no fault-injection harness built (see Deferred/YAGNI in the plan). +- **Rejected alternatives:** + - Re-run the 46-trial spike — rejected; the inline-vs-forked risk is retired by T1, so re-running re-pays a settled cost. + - Build a CI/lint/manifest-validator as part of this refactor — rejected; no such tooling exists and no incident justifies standing it up now (YAGNI); the manual pre-delete grep gate is the proportionate control. + - Build an API-layer fault-injection harness to force `api_retry` — rejected; the spike frames it as a future trigger, not a precondition, and the fault cannot be reliably induced (YAGNI). +- **Specialist owner:** test-engineer +- **Revisit criterion:** The suite gains a build/test/CI surface, or an operator observes a consumer early-exiting right after a `readability-guidance` call in real usage (reopens the fault-injection harness). +- **Dissent (if any):** None recorded. +- **Driven by rounds:** R1 +- **Dependent decisions:** — +- **Referenced in plan:** Testing Strategy, Decomposition and Sequencing diff --git a/docs/plans/han-communication-plugin/artifacts/implementation-iteration-history.md b/docs/plans/han-communication-plugin/artifacts/implementation-iteration-history.md new file mode 100644 index 00000000..8cef3f39 --- /dev/null +++ b/docs/plans/han-communication-plugin/artifacts/implementation-iteration-history.md @@ -0,0 +1,38 @@ +# Implementation Iteration History: han-communication Plugin + +Round-by-round record of the `plan-implementation` team discussion.

The three vendored reference copies in `han-coding`, `han-github`, and `han-reporting`, and the four `han-core` originals, are gone — `find` returns exactly one copy of each reference file. All 13 consumer skills source the standard by invoking `han-communication:readability-guidance`; the 9 synthesis skills additionally dispatch `han-communication:readability-editor` with no rule-path argument; the 4 draft-and-self-check skills run no rewrite. Six plugin manifests declare the new dependency edge (`han-core` for the first time), both marketplaces list the plugin, and every stale doc pointer and dependency narration is updated. No version is bumped. + +## Context + +- **Driving constraint:** A user-directed refactor to give the suite's readability standard one unambiguous owner and remove the byte-identical vendored duplication (spec [D1](artifacts/decision-log.md#d1-introduce-han-communication-as-a-foundational-plugin), [D3](artifacts/decision-log.md#d3-source-the-standard-cross-plugin-not-inline)). The load-bearing mechanism risk (same-context sourcing) was retired by the OI-3 spike before planning began ([T1](artifacts/feature-technical-notes.md#t1-same-context-composition-the-guidance-skill-is-inline-not-forked)), so the gate is clear. +- **Stakeholders:** Operators running prose-producing Han skills (output must meet the same standard, applied in the same stages, after the move); contributors maintaining the suite (one canonical copy to edit, no re-vendoring); the primary plugin loader (resolves the six new direct edges); Codex-based operators (install the plugin explicitly since Codex resolves no dependencies). +- **Future-state concern:** `han-communication` is the first plugin to co-locate a skill and an agent outside `han-core`, and `han-core` takes its first-ever dependency — both invert previously-stated invariants, so the docs sweep must reframe those rules rather than leave them half-true ([D-6](artifacts/implementation-decision-log.md#d-6-repo-wide-docs-and-narration-sweep-by-grep-with-the-agents-live-in-han-core-exception)). The residual `api_retry` early-exit risk is reduced by inference, not measured; it is watched via a documented troubleshooting note, not new machinery. +- **Out-of-scope boundary:** No change to the content of the readability rule, the writing-voice profile, the editor's rewrite behavior, or the staged application model (spec Out of Scope). No dependency for `han-planning`, `han-linear`, `han-feedback`, or `han-plugin-builder`. No version bumps applied. No CI/lint/fault-injection tooling built (see Deferred). + +## Team Composition and Participation + +| Specialist | Status | Key Input | +|------------|--------|-----------| +| `project-manager` | Coordinator | Facilitated R1–R2 and synthesized this plan. | +| `junior-developer` | Active | Riskiest-ordering (delete-last, grep gate); the "agents live in han-core" exception; coupled rename-and-drop edit; count-free indexes. | +| `structural-analyst` | Active | Verified the six-plugin edge list from scratch; the module layout and new-plugin-category observation; efferent coupling 0, no cycle. | +| `devops-engineer` | Active | RECON-1 (Codex surface already exists, extend not build); the six safe-sequencing phases; PR grouping; rollback via `git revert`. | +| `test-engineer` | Active | V1–V13 static checks plus the light V6 smoke; do-not-re-run the spike; accept the `api_retry` residual risk as documented. | + +## Implementation Approach + +The refactor is content-and-manifest surgery on a Markdown-plus-JSON plugin suite with no build system. The shape is: stand up the new plugin additively, declare the dependency edges, rewire the consumers, delete the originals last behind a grep gate, then sweep docs. Nothing runs at runtime that this plan introduces beyond the existing skill-invocation and agent-dispatch primitives. + +### Architecture and Integration Points + +`han-communication` is a new foundational layer beneath every other plugin, depending on nothing (efferent coupling 0, so no cycle) ([D-1](artifacts/implementation-decision-log.md#d-1-direct-dependency-edge-list-six-declaring-plugins), [D-7](artifacts/implementation-decision-log.md#d-7-han-communication-module-layout)). Its layout co-locates the `readability-editor` agent, the `edit-for-readability` and new `readability-guidance` skills, and both reference files in one `references/` directory, preserving the `skills/{name}/SKILL.md` + `../../references/{file}.md` two-level path that `edit-for-readability` depends on ([D-7](artifacts/implementation-decision-log.md#d-7-han-communication-module-layout)). Six Claude manifests gain the dependency edge — `han-core`, `han-coding`, `han-github`, `han-reporting`, the `han` meta-plugin, and `han-atlassian` — with `han-core` receiving its first-ever `dependencies` key, value `["han-communication"]` ([D-1](artifacts/implementation-decision-log.md#d-1-direct-dependency-edge-list-six-declaring-plugins)). The Codex surface already exists and is **extended**, not built: a new `.codex-plugin/plugin.json` and a `.agents/plugins/marketplace.json` entry, with zero Codex dependency or description edits ([D-4](artifacts/implementation-decision-log.md#d-4-extend-the-existing-codex-surface-zero-codex-dependency-or-description-edits)). + +### Runtime Behavior + +The new `readability-guidance` skill is **inline** — it must not set `context: fork` — so the standard it surfaces persists in the caller's context and the caller resumes its own workflow ([T1](artifacts/feature-technical-notes.md#t1-same-context-composition-the-guidance-skill-is-inline-not-forked)). Each of the 13 consumers invokes it by qualified name at the drafting point. The 9 synthesis skills additionally dispatch `han-communication:readability-editor` as one coupled edit that renames the namespace and drops the now-dead `../../references/readability-rule.md` argument; the editor reads its own co-located canonical rule ([D-3](artifacts/implementation-decision-log.md#d-3-editor-invocation-contract-rename-plus-drop-rule-path-arg)). gap-analysis's size-conditional editor skip is preserved; the 4 draft-and-self-check skills gain the guidance invocation but no editor dispatch ([D-3](artifacts/implementation-decision-log.md#d-3-editor-invocation-contract-rename-plus-drop-rule-path-arg)). + +## Decomposition and Sequencing + +Six ordered phases; every phase before Phase 4 is additive, so the suite stays runnable throughout ([D-2](artifacts/implementation-decision-log.md#d-2-copy-first-delete-last-migration-sequencing)).

ADD the `han-communication` entry to `.claude-plugin/marketplace.json` and to `.agents/plugins/marketplace.json` (`source: {local, path}`, `policy`, `category`; no description, no dependencies) ([D-4](artifacts/implementation-decision-log.md#d-4-extend-the-existing-codex-surface-zero-codex-dependency-or-description-edits), [D-7](artifacts/implementation-decision-log.md#d-7-han-communication-module-layout)). + +**Phase 2 — declare edges and narration (before any rewire).** EDIT the `dependencies` array in the 6 Claude `plugin.json` files, adding `"han-communication"` (`han-core` gains the key for the first time) ([D-1](artifacts/implementation-decision-log.md#d-1-direct-dependency-edge-list-six-declaring-plugins)). Update the dependency-narrating `description` fields for `han`, `han-coding`, and `han-atlassian` in **both** `plugin.json` and the `marketplace.json` mirror, plus the new `han-communication` entry; do **not** touch `han-github` or `han-reporting` descriptions (they carry no dependency narration).

Add the `han-communication:readability-guidance` invocation to all 13 consumers at the drafting point; the 4 draft-and-self-check skills (runbook, issue-triage, ADR, html-summary) gain guidance but no editor dispatch; gap-analysis's size-conditional skip survives. Update the 6 secondary template/reference files that hardcode the rule path (one at a 3-level depth). Rename any `han-core:edit-for-readability` reference to the `han-communication:` namespace. + +**Phase 4 — delete originals last (grep-gated).** Run the pre-delete grep gate (asset strings, both qualified names, any relative or plugin-root path to `readability-rule.md`/`writing-voice.md`); it must come back clean outside the CHANGELOG/research exclusions. Only then DELETE the 6 vendored copies (`han-coding`, `han-github`, `han-reporting` × 2 files) and the 4 `han-core` originals (agent, `edit-for-readability` skill dir, 2 reference files) ([D-2](artifacts/implementation-decision-log.md#d-2-copy-first-delete-last-migration-sequencing)). + +**Phase 5 — docs, indexes, narration sweep.** Move `docs/agents/han-core/readability-editor.md` → `docs/agents/han-communication/` and `docs/skills/han-core/edit-for-readability.md` → `docs/skills/han-communication/`, rewriting their outbound links. Add a `readability-guidance` long-form doc under `docs/skills/han-communication/` with one troubleshooting sentence on the `api_retry` residual risk. Execute the comprehensive grep sweep for classes 3–5 of spec D7, extended with the agent-home seed, reframing "all agents live in han-core" to name the `han-communication` exception ([D-6](artifacts/implementation-decision-log.md#d-6-repo-wide-docs-and-narration-sweep-by-grep-with-the-agents-live-in-han-core-exception)). Keep indexes count-free and add `han-communication` entries. Fix the `han-atlassian` Codex co-requisite doc gap while editing that region ([D-9](artifacts/implementation-decision-log.md#trivial-decisions)). Add a new CHANGELOG entry; leave CHANGELOG and `docs/research/**` history otherwise untouched. + +**Phase 6 — release (deferred).** Version bumps are listed, not applied, with `han-core` a MAJOR candidate; applied only under explicit direction via `han-release` ([D-5](artifacts/implementation-decision-log.md#d-5-version-bumps-listed-but-deferred-to-release)). + +## RAID Log + +### Risks + +| ID | Risk | Likelihood | Severity | Blast Radius | Reversibility | Owner | Mitigation | +|----|------|------------|----------|--------------|---------------|-------|------------| +| R1 | A consumer reference or dependency array is missed, leaving an orphaned pointer or under-declared edge (the commit 05d7562 drift class) | Medium | Medium | One skill or one install path breaks silently | High (`git revert` per phase) | junior-developer | Grep-driven sweep ([D-6](artifacts/implementation-decision-log.md#d-6-repo-wide-docs-and-narration-sweep-by-grep-with-the-agents-live-in-han-core-exception)) and the hard pre-delete grep gate ([D-2](artifacts/implementation-decision-log.md#d-2-copy-first-delete-last-migration-sequencing)); `han-atlassian` treated as highest-verification-priority edit | +| R2 | No CI/linter exists to catch a malformed manifest or a dropped rule-path arg | Medium | Low | Affected manifest or dispatch site | High | test-engineer | Per-phase static `jq`/grep/diff checks V1–V13 plus one install smoke ([D-8](artifacts/implementation-decision-log.md#d-8-manual-verification-static-checks-plus-one-light-smoke-no-ci)) | +| R3 | The `api_retry` early-exit path could not be induced in the spike; residual risk is reduced by inference, not measured | Low | Medium | A consumer could early-exit right after a guidance call | Medium | test-engineer | Accept as documented (troubleshooting sentence in the guidance long-form doc); fallbacks (editor-only delegation, or vendoring for the 4 non-synthesis skills) remain the documented safety net | + +### Assumptions + +| ID | Assumption | What Changes If Wrong | Verifier | Status | +|----|------------|-----------------------|----------|--------| +| A1 | The inline (non-forked) same-context sourcing holds in real usage as it did across the spike's 34/34 runs | If it early-exits, a consumer abandons remaining steps; fall back to editor-only or vendoring | test-engineer via V6 smoke | Reduced by inference (T1); `api_retry` unmeasured | +| A2 | The primary loader resolves the 6 direct edges (no transitive reliance needed) | If not, the plan already avoids transitive reliance, so direct edges cover it | structural-analyst | Held under spec review; direct-edge design removes the dependence | + +### Dependencies + +| ID | Dependency | Owner | Status | +|----|------------|-------|--------| +| Dep1 | Whether a Codex-based agent can dispatch the editor **agent** (spec OI-2) | contributor, independent of this feature | Open, non-blocking — guidance and skill invocations do not depend on it, and synthesis skills' editor dispatch predates this move | +| Dep2 | `han-release` applies the deferred version bumps at release time | devops-engineer / `han-release` | Deferred to release ([D-5](artifacts/implementation-decision-log.md#d-5-version-bumps-listed-but-deferred-to-release)) | + +## Testing Strategy + +Verification is manual; the repo has no build system, test harness, linter, or CI ([D-8](artifacts/implementation-decision-log.md#d-8-manual-verification-static-checks-plus-one-light-smoke-no-ci)). + +- **Observable behaviors to test:** all 13 consumers source the standard via `han-communication:readability-guidance` (V1–V13); the 9 editor dispatches are renamed with the rule-path arg dropped and the 4 draft-and-self-check skills dispatch no editor; the self-check blocks are byte-identical pre/post; after Phase 4, `find readability-rule.md` and `find writing-voice.md` each return exactly 1; no `han-core:readability-editor` / `han-core:edit-for-readability` name survives outside CHANGELOG and docs/research; the 6 dependency edges are present and the 4 excluded plugins absent; both marketplaces carry the entry. +- **Test doubles posture:** not applicable — static content checks (`grep`, `diff`, `jq`, `find`), not executable-code tests. +- **Edge cases requiring coverage:** the 3-level-depth secondary template path in html-summary; gap-analysis's size-conditional editor skip; the historical-artifact guard (CHANGELOG/research must stay unchanged). +- **Test levels:** static per-phase checks (V1–V13) as the primary layer; one light dynamic smoke (V6) — 2 real heavy consumers (for example `investigate` or `architectural-analysis`, and `runbook`), 2 runs each, judged from on-disk artifacts, confirming the guidance skill ran same-context with no `context: fork`.

Its one aim: when a user runs a reader-facing skill, the human-facing deliverable it produces can be found, understood, and used by a reader who did not do the work and lacks the author's context. + +That aim is pursued through observable properties of the text, not a comprehension score. The output leads with its main point, gives each paragraph one idea, uses descriptive headings, keeps sentences short and active, prefers common words, and reveals detail in layers. The observable gate on those properties is the standardized self-check at the end of this rule. The standard commits to that check, not to a promise about a reader's comprehension. + +This rule is loaded and applied at runtime, the same way skills load the shared YAGNI rule (`yagni-rule.md`) and evidence rule (`evidence-rule.md`). Loading the rule does not by itself make output readable. The rule takes effect through three mechanisms a skill wires in: the output **template** carries the structural rules, an always-on **audience frame** shapes the drafting, and a discrete **self-check** runs after the draft exists. Applying all of it as one stacked instruction block reproduces the failure it exists to dodge, so a skill applies one stage at a time. + +## Who reads reader-facing output + +A skill is **reader-facing** when its primary deliverable is human-facing prose that a non-author reads end to end to understand something: a finding, a summary, a plan of record, a document. Skills whose primary output is code, or a structured specification / plan / work-item / standard consumed mainly by downstream skills, are not reader-facing and do not apply this rule. + +## The audience frame + +While drafting, write for a capable reader who **did not do this work and lacks the author's context**. This single instruction is the most practical lever for plain output: it steers away from insider shorthand, unstated assumptions, and the author's own mental model. + +A skill whose real reader is a specific expert names that reader instead of defaulting, and may scope the frame per section so technical specifics the reader needs are not simplified away. An engineer reading a root-cause finding needs the function names and the exact failing condition; the frame governs *how* that is said (lead with the answer, plain framing, progressive disclosure), never whether the necessary technical facts appear. + +## What the standard requires + +These are the output properties. They shape the skill's template so the draft is born with them, rather than being bolted on afterward. + +- **Main point first.** The opening line states the main point (bottom line up front). A reader who stops after one sentence still gets the answer. +- **One idea per paragraph.** Each paragraph carries one idea, and its first sentence carries the weight. A reader scanning first sentences follows the whole argument. +- **Descriptive headings.** Each heading names its content rather than a generic label ("Why the request times out," not "Analysis"), so a reader scanning headings can navigate. +- **Short, active sentences.** Sentences are short (roughly fifteen to twenty words on average) and active by default. Few run past twenty-five to thirty words. +- **Common words.** Prefer the common word over the technical synonym. Define a term on first use when it cannot be replaced. +- **No blocklisted words.** Apply the vocabulary blocklist (below) for word-level rules. +- **Numbered lists for steps, bullets for the rest.** Number anything sequential; bullet anything that is not. +- **Progressive disclosure.** Reveal the core first and detail in layers. The reader meets the essential idea before the qualifications, the edge cases, and the supporting evidence. +- **Technical detail follows the prose.** Keep implementation and technical references — symbol names, file paths, flags, exact code — out of the human-readable paragraphs as much as possible. Where one cannot be left out, keep it as small as the sentence needs and include it only when the reader needs it to follow the point. Otherwise the technical detail comes after the prose that describes it, in one or more code fences the prose has already explained. The readable language says what the detail shows. + +The applied set is kept deliberately tight. Structural rules that fit only a minority of deliverables (for example "conditions before instructions") are left out on purpose, so the set stays small enough to apply without the compliance decay that comes from stacking instructions. + +## Length guidance + +The length rules are qualitative for drafting and have one concrete anchor for the self-check. While drafting, keep sentences short (the fifteen-to-twenty-word average above), because hard numeric caps get overshot and strip the connective tissue that makes prose cohere. For the self-check, treat any sentence past a **soft threshold of about thirty words** as a candidate to split. That flag is a review trigger, not a hard cap. A longer sentence can stand if it reads clearly and splitting it would hurt. + +## The vocabulary blocklist + +For word-level rules, use the existing writing-voice blocklist in [`writing-voice.md`](./writing-voice.md) (its "Avoided words and phrases" and "AI slop to avoid" sections). That blocklist is authoritative for the words it covers. A skill that keeps its own word list retains it only for the domain-specific terms the shared list does not cover, layered on top rather than duplicating it. The shared list wins on any word both cover. + +## Prose only + +The self-check and any rewrite operate on **prose regions only**. Content inside code fences, diagram bodies (for example the body of a Mermaid chart), rendered markup (an HTML report's tags and class names), and inline citation identifiers is neither evaluated nor altered. Citation identifiers in particular survive unchanged so they still resolve to their registry. Where a deliverable's readability is substantially visual (a rendered HTML report), the self-check applies to its prose content and its visual layout stays governed by the skill's own layout conventions. + +## Fidelity wins + +Every fact in the draft is preserved. If reading more simply would drop or blur a fact, fidelity wins. Every claim, quantity, named entity, and stated condition or qualifier survives with its precision intact. Flattening "exceeded 340ms in three of ten windows" to "was sometimes slow," or "only when X and Y both hold" to "generally," is a fidelity failure, not a simplification. The standard governs how the content is said, never whether a required fact appears. + +## The standardized self-check + +After the draft exists, run this self-check as a discrete pass over the prose regions. It evaluates concrete, behaviorally-anchored yes/no criteria, never "is this clear?" Anything it fails is corrected before the deliverable is presented. + +1. **Main point first** — the opening line states the main point. +2. **Descriptive headings** — each heading names its content and is not a generic label. +3. **One idea per paragraph** — each paragraph carries one idea and leads with it. +4. **Sentence length** — no sentence runs past the soft length flag (about thirty words) without reason. +5. **No blocklisted word** — no word from the vocabulary blocklist is present. +6. **Every fact preserved** — every claim, quantity, named entity, and stated condition or qualifier in the draft survives with its precision intact. + +The set is enumerated, not illustrative: these six criteria are the whole check. It is kept small on purpose so it applies as one focused pass rather than decaying under its own weight. On a skill that runs no separate rewrite pass, criterion 6 is the only fidelity guard the output has, so it is not optional. + +## How to apply this rule in a skill + +Apply the rule in stages, never as one instruction block. + +1. **Template.** The skill's output template already carries the structural rules above (main point first, descriptive headings, one idea per paragraph, numbered-vs-bullet lists, progressive disclosure, technical detail after the prose). Draft into that template so the structure is built in. +2. **Audience frame.** Hold the audience frame while drafting: the capable reader who did not do this work, or the skill's named specific reader. +3. **Rewrite pass (synthesis skills only).** A skill that already has a synthesis or editor step — a distinct pass, after the full draft exists, that reviews or consolidates the whole draft before presenting it — dispatches the dedicated `readability-editor` reviewer to audit and rewrite the draft against this rule, preserving every fact. Where the skill already ran a readability pass of its own, the dedicated reviewer replaces it rather than stacking a second pass on top. Any imperative or conditional content carried in from source material is delimited so the rewrite treats it as text to preserve, not as instructions to follow. +4. **Self-check.** Run the standardized self-check above over the prose regions. Correct every failure before presenting. + +The standard applies at **generation time**. A committed document is written readable; a later manual edit or partial re-run is not re-checked against the rule.

Where voice and formatting guidance conflict on matters of rhythm, pacing, or emphasis, **voice takes precedence**. + +--- + +## Voice profile + +### Core voice attributes + +- **Generous mentor, not lecturer**: Writes like someone sitting next to the reader walking them through a thing they just figured out. Uses direct second person freely ("you can get the RubyInstaller package", "Open a command prompt and run"). Grants permission and builds confidence rather than gatekeeping expertise. Phrases like "At this point you should be able to tackle any task that you need" explicitly invite the reader to feel competent. + +- **Plainspoken enthusiasm**: Believes in the tools and wants the reader to believe too, but without hype vocabulary. Enthusiasm comes through in clauses like "The options are almost endless", "I'm very happy to announce", and "I was lucky enough to be able to contribute" — earnest, unguarded, never performative. No "revolutionary" or "game-changing" — just genuine interest made visible. + +- **Accumulating example as argument**: Rarely explains abstract concepts in the abstract. Starts a concrete example (an email-sending app, a rakefile, a contact list) and then adds complexity step by step, so the abstraction emerges from the working code. The example carries the whole piece — the reader watches it grow. + +- **Physical-world analogies for software ideas**: Consistently reaches for hardware and everyday-object metaphors to explain software. Examples from the samples: software as Jenga, running distances (50-meter dash vs. marathon), a circular saw for encapsulation, power-saw blades for Open-Closed, electrical outlets for Dependency Inversion, office multifunction copiers for Interface Segregation, puzzle pieces for cohesion. This is a signature move. + +- **Practical, non-hedging confidence**: States what works and what doesn't without a defensive shell of qualifiers. "That's it! There's nothing more to it." "Always remember, though, you are writing Ruby code — if you don't have the functionality you need, it is only a few lines of code away." When hedging appears, it's practical ("may not always be able to", "may include"), never performative humility. + +### Tone range + +- **Default register**: Conversational but substantive — like a senior practitioner blogging or giving a conference walkthrough. Informal enough to use a `:)` emoji and first-person warmth; formal enough to carry a full technical argument with running code. + +- **Technical or analytical**: Builds by accretion. Opens with history and context (early build tools, NAnt, MSBuild), then introduces the subject, then walks through increasing complexity with a single running example. Explains *why* a change is being made before showing the code. Names tools and versions specifically rather than speaking generically — "CruiseControl.NET", "ruby-1.8.6-p383-rc1.exe", "nunit-console.exe", "Addy Osmani's Backbone Fundamentals book". + +- **Personal or narrative**: Warmest and most compact in short blog announcements — gracious, grateful, quick to name collaborators by their Twitter handles and give them credit ("Core Contributors: Jarrod Overson and Tony Abou-Assaleh"). Uses the word "finally" when something long-awaited has arrived ("I finally have a couple of other core contributors"). + +- **Persuasive**: Rarely argues against a foil. Persuades by showing the better version working, then naming the benefit at the end. Closing benefit lists are characteristic ("Low Coupling", "High Cohesion", "Strong Encapsulation", "System Flexibility" as the payoff section of the SOLID article). + +### Sentence and rhythm patterns + +- **Typical sentence length**: Medium to long, load-bearing sentences that carry a full step of reasoning. Doesn't chop into terse aphorisms. Average sentence often 20–35 words with embedded clauses. Short punch sentences appear at moments of relief or closure: "That's it!" "The options are almost endless." "Albacore project aims to do precisely that." + +- **Paragraph rhythm**: Paragraphs tend to be 3–5 sentences: state the concept, supply a practical detail or example, close with the implication or next step. Code blocks are a structural beat — text sets them up, text picks them back up. + +- **Transitions**: Uses explicit connectives generously — "However,", "First,", "Second,", "Lastly,", "Notice that…", "At this point,", "To do this,", "Now that you know where…". Ordinal signposting ("First, Second, Third, Lastly") is a signature move in technical walkthroughs. Paragraphs step-by-step rather than leaping thematically. + +- **Questions**: Used sparingly and always load-bearing — typically as a framing device at the top of a new section ("What are the 'raw materials' or 'unfinished goods' that we need to track as inventory?"). Never ornamental. + +--- + +## Vocabulary and phrasing + +### Characteristic words and phrases + +- "In this article, I will show you…" — characteristic opening framing for long-form tutorials. +- "That's it!" — punctuates a moment where something turned out to be simple. +- "The good news is…" / "The good news in this somewhat ambiguous situation is…" — common transition into a reframe. +- "Always remember," / "Remember that," / "Notice that…" — mentor-voice asides that break the fourth wall. +- "At this point you should be able to…" — permission-granting closer that acknowledges the reader's progress. +- "help to" / "helps you" (over "enables" or "empowers") — "this helps to give Rake a very broad user base", "Albacore makes it easier to maintain". +- "out of scope for this article" / "discussed later" / "is beyond the scope" — explicit boundary-drawing. +- "real-world" as an adjective for practical problems. +- "simple", "easy", "straightforward" — used sincerely, not as sales words. +- Uses `:)` as in-text emoji casually: "Lather, rinse, repeat. :)", "Google :)". +- Gratitude framing in short-form: "I'm very happy to announce", "I was lucky enough to", "I finally have". +- Lists collaborators by name, with their handles/links, when crediting them. + +### Avoided words and phrases + +Based on what's conspicuously absent across the samples: + +- No em-dash, '—', anywhere, ever. +- No "leverage" as a verb. Always "use". +- No "utilize". Always "use". +- No "empower", "unlock", "revolutionize", "game-changing", "transformative". +- No "at the end of the day", "circle back", "deep dive", "let's dive in". +- No performative hedging ("arguably", "one might say", "it could be argued") — states the claim plainly. +- No "showcase" as a verb. Prefers "show", "demonstrate", "illustrate". +- No "robust" as a vague positive. +- No sports metaphors as decoration — the running-distance metaphor appears as actual load-bearing analogy, not flavor. +- No "actually" - this is rude, and indicates that the reader was wrong +- No "just" - this assumes the information is easy to understand or follow, and can make readers feel insulted for not understanding + +### Technical language habits + +- **Approach to jargon**: Uses practitioner shorthand freely when the audience is clearly developers. When an acronym or term is central to the piece (SOLID, TOC, LSP, SPA, CFD), spells it out on first use and then uses it. Does not talk down, but also does not assume too much — will pause to explain a single Ruby keyword like `require` when it matters to the walkthrough. +- **Acronyms**: Expanded on first use ("Theory of Constraints (TOC)", "Cumulative Flow Diagram (CFD)", "Single Page Applications (SPAs)"). After that, uses the acronym freely. +- **Code and technical references**: Heavy use of inline code snippets as part of the argument, not as illustration after the fact. Code is central to the article's motion — the reader builds up a working artifact. Names specific libraries, versions, CLI flags, file paths ("C:/Windows/Microsoft.NET/Framework/v3.5/msbuild.exe", `/p:Configuration=Release`) rather than speaking abstractly. Prefers showing over telling. Even so, keep the dense technical detail — long paths, exact code, flag strings — in the code block, not crammed into the readable sentence. The prose stays plain and says what the code shows, and where a reference has to sit inline, it is kept as small as the sentence needs. The reader meets the point in words first, then the code that backs it — a passage can pick up several code fences in a row, as long as the prose is describing what each one shows. + +--- + +## Structural tendencies + +### How they open + +Two dominant opening moves in the long-form pieces: + +1. **Historical framing**: Opens with a short history of the problem space to situate the reader before introducing the subject. The Rake article opens with "Automated build tools have been around for a long time. Many of the early tools were simple batch scripts…" and only arrives at Rake two paragraphs later. The SOLID article opens with "Software development does not have to resemble a game of Jenga…" then broadens to the three OO principles before introducing SOLID itself. + +2. **Personal announcement**: In short blog posts, opens with unguarded first-person news — "I'm very happy to announce that this week's addition to Addy Osmani's Backbone Fundamentals book is a chapter on Marionette!" No throat-clearing; the news is the opening. + +Rarely opens with a thesis statement or a hot take. + +### How they close + +Long-form pieces tend to close with one of: + +- A **benefits recap** that names each property of the finished design as a subheading ("Low Coupling", "High Cohesion", "Strong Encapsulation", "System Flexibility") and explains how the piece delivered each. +- A **circle back to the opening metaphor** in a final short paragraph — the SOLID piece closes by returning to the marathon-pace metaphor: "Like a marathon runner establishing a sustainable pace based on distance rather than sprinting throughout, software development succeeds when…" +- A **pragmatic handoff** — "At this point you should be able to tackle any task that you need" or "The options are almost endless." + +Short-form pieces end on logistics and gratitude — links, Twitter handles, contact info — not a summary. + +### Use of examples and evidence + +Strongly prefers a single running example that grows through the piece. The SOLID article is the email-sending app, refactored five times. The Rake article is a rakefile, expanded from "Hello From Rake!" through MSBuild, NUnit, Albacore, YAML config, and publishing. The reader never has to hold multiple unrelated examples in their head; the example *is* the argument. + +When claiming a benefit or drawback, shows it in the code before naming it. When naming a tool, names the specific tool, its version if relevant, and often its source URL — nothing is left abstract. + +### Humor, metaphor, and personality + +Dry, warm, never at anyone's expense. "Christmas tree of doom" for nested jQuery callbacks. "Lather, rinse, repeat. :)" for the repeat-step of TOC. A `Google :)` reference in a bibliography. Signed CODE Magazine pieces with a personal ("I hope you enjoy reading it as much as I enjoyed writing it") that would be edited out of most magazine copy. The personality sits inside the technical prose rather than being staged as a separate voice. + +--- + +## Content type variations + +### Long-form (blog posts, articles, essays) + +10–40 KB pieces. Structured with H2 headers for major sections and H3–H4 for substeps. Lots of code blocks interleaved with prose that sets them up and picks them back up. Tables or flat bullet lists used for enumerations (TOC production metrics, Albacore task list, required API endpoints). A running example threads through the entire piece. Conclusion section circles back to the opening metaphor or benefits-recap. + +Three of the samples (SOLID 2009, jQuery/Backbone 2013 for CODE Magazine) read as **more heavily edited into a third-person magazine voice** than the baseline — "The developer identifies two distinct change points" rather than "You'll identify two distinct change points". Treat this register as an editorial overlay, not the writer's native voice. Rake 2010 (also CODE Magazine) retained the native voice; the difference is informative. + +### Short-form (social posts, summaries, abstracts) + +Warm, first-person, immediate. The 2012 Marionette Fundamentals announcement opens "I'm very happy to announce" and closes with credits and handles. The 2012 screencast announcement is compact promotional prose with no throat-clearing. Short form *intensifies* first-person presence rather than stripping it. + +_Caveat: Only two short-form samples are present, and both are announcement-shaped. Conversational social posts, replies, or threaded commentary are not represented — that voice would need to be inferred or additional samples provided._ + +### Technical or reference writing + +When the piece is a tutorial, second-person imperative dominates ("Open a command prompt", "Type the following contents", "Add this code to your rakefile"). Precise about paths, flags, versions. Does not pad procedure with extra explanation — shows the code, explains the non-obvious part once, moves on. Happy to flag when a topic is out of scope ("The setup of a ClickOnce project is out of scope for this article. There are plenty of resources online…"). + +--- + +## AI slop to avoid + +### Standard (all writing) + +Never use: "It's worth noting", "Importantly", "At the end of the day", delve, foster, synergy, underscore, pivotal, showcase, robust, leverage, utilize, "paradigm shift", "game changer", "spoiler alert", "Let's dive in", "In today's fast-paced world", the "Question? Answer." header pattern, "This isn't about X. It's about Y.", "Full stop." + +### Specific to River + +- Never strip out first-person presence in long technical articles. If the piece has "I will show you", "I am going to assume", or "I was lucky enough" in the original, keeping that voice is non-negotiable. Editorial rewrites that flatten this into third-person developer-as-character prose ("The developer identifies…", "Developers should examine…") are a known failure mode — the magazine rewrites in the sample set show exactly this drift. +- Never replace direct "you" with generic third-person subjects ("a developer", "the reader", "one"). When instructing, address the reader directly. +- Never replace `use` with `leverage` or `utilize`. The sincere, plain verb choice is load-bearing. +- Never announce a joke or punchline-ify a metaphor. The humor sits inside the technical sentence; it is not staged. +- Never invent a benefits list or a marketing-flavored closing. Benefits recaps come from the actual properties demonstrated in the article's running example, named plainly. +- Never remove the `:)` emoji or soften a casual aside ("Lather, rinse, repeat. :)") into formal prose. The warmth is part of the voice. +- Never drop specific tool names, versions, URLs, or collaborator credits in favor of generic references. +- Don't open with a thesis statement. Open with history, context, or personal news. + +--- + +## Sample passages + +### Sample 1 + +**Source**: Article: "Building .NET Systems with Ruby, Rake and Albacore", CODE Magazine, 2010-05-07 + +> Automated build tools have been around for a long time. Many of the early tools were simple batch scripts that made calls out to other command-line tools like compilers and linkers. As the need for more complexity in the build scripts was realized, specialized tools like Make were introduced. These tools offered more than just sequential processing of commands. They provided some logic and decision making as well as coordination of the various parts of the build process. +> +> Rake - the "Ruby Make" system - may not have much more than its namesake to claim a connection to Make, but it is a build tool that is quickly growing in popularity and providing .NET developers with new options. +> +> […] +> +> The Albacore project is a suite of Rake tasks that is targeted at building .NET systems. In this article, I will show you how to get your .NET project building with Ruby, Rake and Albacore. I will also demonstrate some of the more advanced features of Albacore to help manage the configuration of your build process, generate project configuration files at build time, publish your project output, and more. The goal is to create a build script that is simple to set up, easy to read and easy to update. + +**What to notice**: Historical opening rather than a thesis. Short paragraph-closing sentence for emphasis ("provided some logic and decision making as well as coordination of the various parts of the build process."). The author's first-person arrival ("In this article, I will show you") comes after the subject has been situated. Enthusiasm is earned through contextualization, not asserted. Plain words — "simple to set up, easy to read and easy to update" — do the selling. + +### Sample 2 + +**Source**: Paper: "The Theory of Constraints: Productivity Metrics in Software Development", 2009 + +> This paper is largely based on the work of David J. Anderson, in "Agile Management For Software Engineering". It also includes some of my own interpretations and understandings of the Theory of Constraints. The original intent of this paper was to facilitate the discussion of productivity and metrics in the Development Department at McLane Advanced Technologies, LLC. This paper is not intended to be a comprehensive or exhaustive discussion of the points within, but it intended to spur additional research and conversations. I hope you enjoy reading it as much as I enjoyed writing it. +> +> […] +> +> There are five basic steps outlined by TOC, to accomplish these goals: +> +> 1. Identify the constraint(s) +> 2. Exploit the constraint to maximize productivity +> 3. Subordinate all other steps or processes to the speed or capacity of the constraint +> 4. Elevate the constraint – in other words, work to remove the current constraint, leading to higher capacity or production rate for the entire system +> 5. Lather, rinse, repeat. :) + +**What to notice**: The paper opens with sourcing and intent rather than a claim, crediting the reference work and naming the organizational context (a specific company's development department). The closing line of the warm-up paragraph ("I hope you enjoy reading it as much as I enjoyed writing it") is the kind of sentence an editor would delete — and it's exactly what makes the voice recognizable. Note the `:)` in the fifth bullet: humor inside the technical list, not separate from it. This is how the voice handles levity. + +### Sample 3 + +**Source**: Blog post: "Backbone Fundamentals, Intro To Marionette, TodoMVC, And More", lostechies.com, 2012-09-13 + +> I'm very happy to announce that this week's addition to Addy Osmani's Backbone Fundamentals book is a chapter on Marionette! +> +> I was lucky enough to be able to contribute a large portion of the chapter to the book, including a brief introduction to some of the benefits that Marionette provides for Backbone applications. There's a discussion on the Marionette version of the TodoMVC application, the architecture that I used based on Marionette, and some links to additional implementations that use Marionette without any modules, and with RequireJS. +> +> […] +> +> In addition to the chapter in this book, there are a number of other things happening with Marionette. I finally have a couple of other core contributors that are helping to run things, and keeping things moving. There's a new website in the works, a logo in the works, an IRC channel and a twitter account. +> +> Core Contributors: Jarrod Overson and Tony Abou-Assaleh + +**What to notice**: Short-form voice at its most characteristic. First-person from the first word. Credits collaborators by name, with links (stripped here for readability but present in the original). Gratitude framing — "I was lucky enough", "I finally have" — is sincere, not performative. No throat-clearing opener. Ends on logistics (handles, links, IRC channel) rather than a summary. diff --git a/han-communication/skills/edit-for-readability/SKILL.md b/han-communication/skills/edit-for-readability/SKILL.md new file mode 100644 index 00000000..24c7f1a5 --- /dev/null +++ b/han-communication/skills/edit-for-readability/SKILL.md @@ -0,0 +1,71 @@ +--- +name: edit-for-readability +description: > + Applies Han's shared Human-Readable Output Standard to a target you already have — a file on + disk, text pasted into the prompt, or a draft already produced in the conversation — by + dispatching the readability-editor to rewrite its prose so the main point comes first, headings + are descriptive, each paragraph carries one idea, and sentences stay short and active, while + preserving every fact.

Never guess at a file to overwrite. + +For a file target, confirm the file exists and read it. Use `Glob`/`Grep` to resolve a partial name to a concrete path.

If the user names a specific reader (an engineer implementing a fix, a PR reviewer, a non-technical stakeholder), carry that reader to the editor instead so the technical specifics that reader needs are kept. + +## Step 2: Confirm before rewriting a file in place + +If the target is a file on disk (not a scratch copy of pasted text or a conversation draft), tell the user which file will be rewritten in place and that every fact is preserved, then get a go-ahead before dispatching.

This commit fixes the two shellcheck findings and the broken symlink. - init-guidance.sh: the first sed expression matches the literal text "${CLAUDE_PLUGIN_ROOT}" as it appears in the vendored SKILL.md, so the single quotes are required and SC2016 is a false positive. Disable the check at that call with a comment explaining why. - upload-screenshots.sh: verify_on's retry loop never reads its counter, so SC2034 fired on it. Use the conventional throwaway `_` instead. - .claude/rules/plugin-entity-taxonomy.md: the symlink still pointed at docs/guidance/, which ad6ee13 moved to han-plugin-builder/skills/guidance/references/. That commit rewrote the adjacent .claude/rules/ text references but could not catch a symlink target.

Use when releasing, cutting a release, shipping a new Han version, publishing release notes, or tagging + a version. Reads each plugin's target version from its plugin.json; when a plugin has not been bumped past the latest + tag yet, it proposes a semantic-versioning bump and confirms the whole plan before continuing.

The new `han-coding/skills/tdd/references/test-selection.md` is the canonical reference for the Transformation Priority Premise (TPP) and ZOMBIES heuristics: it carries the fourteen-transformation TPP ranking table (from `{} → nil` through `case`) and the ZOMBIES ordering, both resolving to the same answer, that the next test is the one satisfiable by the simplest transformation of the code. The reference frames Robert C. Martin's core principle: as the tests get more specific, the code gets more generic. It is explicit that these are heuristics for choosing what to test next, never a menu for hacking an implementation to green after the test is chosen. - -`han-coding/skills/tdd/SKILL.md` wires the reference in at two points. When ordering the behavior test list, a behavior that expands into several candidate tests (the empty case, the single case, the many case, the boundaries) is ordered simplest-first, Zero then One then Many, so each test forces the smallest generalization of the code, pulling `references/test-selection.md` when the order is not obvious. When picking the next item, the skill prefers the item whose passing requires the simplest transformation (a test needing only a constant return before one forcing a conditional, and a conditional before a loop), and when every remaining item forces a big leap with no smaller test in between, the skill treats that as a missing test and adds it to the list. The skill's `description` gains the TPP and ZOMBIES trigger wording.

The new `han-coding/skills/tdd/references/test-selection.md` +is the canonical reference for the Transformation Priority Premise (TPP) and ZOMBIES heuristics: it carries the +fourteen-transformation TPP ranking table (from `{} → nil` through `case`) and the ZOMBIES ordering, both resolving to +the same answer, that the next test is the one satisfiable by the simplest transformation of the code. The reference +frames Robert C. Martin's core principle: as the tests get more specific, the code gets more generic. It is explicit +that these are heuristics for choosing what to test next, never a menu for hacking an implementation to green after the +test is chosen. + +`han-coding/skills/tdd/SKILL.md` wires the reference in at two points. When ordering the behavior test list, a behavior +that expands into several candidate tests (the empty case, the single case, the many case, the boundaries) is ordered +simplest-first, Zero then One then Many, so each test forces the smallest generalization of the code, pulling +`references/test-selection.md` when the order is not obvious. When picking the next item, the skill prefers the item +whose passing requires the simplest transformation (a test needing only a constant return before one forcing a +conditional, and a conditional before a loop), and when every remaining item forces a big leap with no smaller test in +between, the skill treats that as a missing test and adds it to the list. The skill's `description` gains the TPP and +ZOMBIES trigger wording.

That is not what the loader does. The rule is now "Keep every command an auto-approvable read-only form", and it describes the real behavior: context injection runs at skill load and never prompts, so a command that is not auto-approvable hard-rejects and stops the skill from loading, and only the first failing command surfaces an error while every command after it is masked. A command auto-approves when every part of it, including each stage of a pipe or chain, is either a built-in read-only command on the loader's fixed allowlist (`cat`, `ls`, `head`, `tail`, `wc`, `grep`, `find` without dangerous predicates, `which`, `echo`, `date`, and read-only `git` and `gh` subcommands) or matched by an explicit `Bash()` rule in `allowed-tools`. Pipes and chains are therefore not forbidden. Four constructs are refused every time, and an `allowed-tools` rule does not rescue them: command substitution `$(...)`, process substitution, subshells and background `&`, and dangerous sub-forms of otherwise-safe tools (`find -exec`, `find -delete`, `sed -i`), where the danger check overrides the grant. The rule still prefers one flag-driven command over a pipe, because each extra stage is one more part that has to stay on the allowlist. New guidance covers keeping each injected value small: bound the output at the source with `-n`, `--stat`, `--name-only`, or `-maxdepth` rather than piping into `head`, since injected output persists in context for the whole run, making `| head -N` a last resort rather than a ban. The reference also documents the `git config --get` edge, where the bare `git config user.name` form is accepted as a lone command but not as part of a chain, and the "What NOT to Use" table is rewritten from "Why It Fails" to "What happens" to match. +The old rule in `han-plugin-builder/skills/guidance/references/skill-building-guidance/context-injection-commands.md` +("Keep commands simple, single commands only") claimed that pipes, `&&`-chains, and redirects fail the loader's prefix +match.

Keep the source normalized, but denormalize it into the point of use, resolving the variation with a deterministic step (a script, or the driver that assembles each dispatch) where one exists. The rule includes a before-and-after example (a reviewer-by-file matrix versus one self-contained block per reviewer) and states its own limit: at small scale (two or three items and inputs, with no growth ahead) a compact table is fine, and the claim that the join trips the model is a reasoned bet by analogy to documented weaknesses in large-table lookup and multi-hop binding, not something a study tests at this scale. +`writing-effective-instructions.md` gains the rule "Resolve variation at the point of use": when a step drives several +similar items that each take a slightly different set of inputs (dispatching sub-agents with different reference files, +or applying rules scoped to different files), do not express the variation as a matrix the model has to join against a +separate list, because that forces an in-head join.

The rename is breaking because a plugin name is both its install identity and the namespace prefix for its agents (dispatching `han.core:research-analyst` is now `han-core:research-analyst`), so any saved install reference, dependency entry, or namespaced agent dispatch using the old dotted name breaks and must move to the hyphenated name. The rename was required for Codex marketplace support: a dot in a plugin name breaks Codex, where the name doubles as the skill and agent namespace prefix, so the whole suite needed Codex-safe (dot-free) names.

The parent `han` plugin keeps its name. A plugin name is its install identity and the namespace prefix for that plugin's agents, so a namespaced dispatch like `han.core:research-analyst` is now `han-core:research-analyst`. Any saved install reference, `dependencies` entry, or namespaced agent dispatch using an old dotted name must move to the hyphenated name. The rename was driven by Codex: a dot in a plugin name breaks Codex, where the name doubles as the skill and agent namespace prefix, so supporting the Codex marketplace required dot-free names across the suite. New guidance `han-plugin-builder/skills/guidance/references/claude-marketplace-and-plugin-configuration/plugin-naming.md` records the rule that a plugin name must be kebab-case with no dot. +Every plugin in the suite was renamed from its dotted name to a hyphenated name: `han.core` to `han-core`, `han.coding` +to `han-coding`, `han.planning` to `han-planning`, `han.github` to `han-github`, `han.reporting` to `han-reporting`, +`han.feedback` to `han-feedback`, `han.atlassian` to `han-atlassian`, and `han.plugin-builder` to `han-plugin-builder`. +The parent `han` plugin keeps its name.

This is the suite-level change that motivated the rename, since Codex cannot use a dotted plugin name. Contributed by [@oppegard](https://github.com/oppegard) in #68, which added the Codex plugin scaffolding, switched the suite to Codex-safe plugin names, clarified the Codex install limits, and pointed the Codex metadata to Test Double. +The suite gains a Codex marketplace manifest at `.agents/plugins/marketplace.json` in the repo root, and every plugin +directory gains a `.codex-plugin/plugin.json`.

Broken cross-skill links were fixed, `docs/skills/han-linear/work-items-to-linear.md` was added, and `CLAUDE.md`, `README.md`, `CONTRIBUTING.md`, `docs/semantic-versioning.md`, `docs/choosing-a-han-plugin.md`, and the skills and agents indexes were updated to the hyphenated names. `CLAUDE.md` notes `plugin-naming.md` in its config-guidance map, and `han-linear` was wired into the top-level docs. +The documentation sweep under `docs/` moved the long-form skill and agent docs from dotted paths to hyphenated paths: +`docs/skills/han.core/...` became `docs/skills/han-core/...` and the agent docs moved the same way.

The skill creates or updates a runbook for a single operational scenario: an alert that has fired, an incident, a recurring scheduled task, or a known failure mode on a live service. It applies a YAGNI preflight before writing: the scenario must be real (the alert has fired, the task recurs, or the failure mode exists on a service that receives traffic) before the skill produces the document. Each invocation produces one runbook. Sibling skill docs gain cross-links to `/runbook` where the handoff is natural, and the long-form operator doc at `docs/skills/runbook.md` describes the YAGNI preflight, the template structure, and how the skill differs from `/project-documentation` and `/architectural-decision-record`.

(PR #21) ### Canonical evidence rule extracted -A new plugin-wide reference ships at `plugin/references/evidence-rule.md`. It defines the three structural principles every evidence-bearing skill and agent now applies (proximity to origin, corroboration across independent sources, explicit labeling when no evidence exists) and the trust-class vocabulary (codebase, web, provided) that grounds the corroboration gate. The trust-class vocabulary originated inside `/research` and is now extracted so other skills and agents share one source of truth instead of restating it inline. The canonical operator-facing summary lives at `docs/evidence.md`, and the rule is threaded through long-form docs for `/research`, `/investigate`, `/gap-analysis`, `/plan-a-feature`, `/plan-implementation`, `/iterative-plan-review`, `/coding-standard`, `/architectural-decision-record`, and `/runbook`, plus the `evidence-based-investigator`, `gap-analyzer`, `junior-developer`, and `project-manager` agents.

(PR #22) ### `/research` output structure: single `Sources` registry -`/research` reports previously ended in two separate sections, `Artifacts` and `References`, which forced the same source to be listed twice when it functioned as both. The two sections are now merged into a single indexed `Sources` registry at the bottom of the report, with stable IDs (A1, A2, ...) and one entry per source carrying link, retrieval date, trust class, plain-language summary, and corroboration status in one place. Implemented in `plugin/skills/research/SKILL.md` and `plugin/skills/research/references/research-report-template.md`. This is an output-shape change in the report `/research` produces; operators reading older research artifacts will still see the old two-section layout, while new runs produce the merged registry.

Each guide walks one complete workflow loop with the specific prompts to run, the decision points along the way, and what to expect from each skill at each step.

(PR #27) ### Documentation drift sweep -A pass across the long-form docs corrects several specific drifts. `docs/skills/update-pr-description.md` is corrected so the description is authored by the `junior-developer` agent in Step 4 rather than reviewed in a separate Step 6 pass, and the step count drops from seven to six. `docs/skills/iterative-plan-review.md` is corrected so iteration caps scale with sizing (small=1, medium=2, large=3) instead of the previously-stated "five iterations for lightweight" claim. `docs/skills/plan-a-feature.md` updates its TL;DR and "What you get back" section to reflect the optional fourth `feature-technical-notes.md` artifact that `/plan-a-feature` already produces. `docs/skills/gap-analysis.md` makes the downstream pairing with `/plan-a-phased-build` explicit so operators know what to run next when the gap analysis is in hand. +A pass across the long-form docs corrects several specific drifts. `docs/skills/update-pr-description.md` is corrected +so the description is authored by the `junior-developer` agent in Step 4 rather than reviewed in a separate Step 6 pass, +and the step count drops from seven to six. `docs/skills/iterative-plan-review.md` is corrected so iteration caps scale +with sizing (small=1, medium=2, large=3) instead of the previously-stated "five iterations for lightweight" claim. +`docs/skills/plan-a-feature.md` updates its TL;DR and "What you get back" section to reflect the optional fourth +`feature-technical-notes.md` artifact that `/plan-a-feature` already produces. `docs/skills/gap-analysis.md` makes the +downstream pairing with `/plan-a-phased-build` explicit so operators know what to run next when the gap analysis is in +hand. -Research artifacts backing the changes in this release land in `docs/research/`: `evidence-hierarchy.md`, `runbook-skill-research.md`, `on-call-engineer-research.md`, `artifacts-references-dedupe.md`, `how-to-docs-structure.md`, `enterprise-ai-tooling-integration.md`, `adhd-application-to-han.md`, and `adhd-application-to-han.with-disambiguation.md`. +Research artifacts backing the changes in this release land in `docs/research/`: `evidence-hierarchy.md`, +`runbook-skill-research.md`, `on-call-engineer-research.md`, `artifacts-references-dedupe.md`, +`how-to-docs-structure.md`, `enterprise-ai-tooling-integration.md`, `adhd-application-to-han.md`, and +`adhd-application-to-han.with-disambiguation.md`. ### Pull requests in this release @@ -772,19 +1419,42 @@ Full changelog: https://github.com/testdouble/han/blob/v2.7.0/CHANGELOG.md#v270 ## v2.6.2 -This release bundles three refactors that tighten how shipped skills and the repo's own guidance load context.

A skill goes here when it publishes a Han artifact to Confluence or Jira through the Atlassian MCP server.

If the skill you are adding fits that description, it applies the shared [Readability](./docs/readability.md) standard. Skills whose primary output is code, or a governed structured artifact (a specification, plan, work-item, or coding standard), are out of scope and skip this section. - -The inclusion test is the guide; the enumerated list in [Readability](./docs/readability.md#scope-which-skills-are-reader-facing) is authoritative. When a new skill passes the test, add it to that list and wire the standard in: - -1. **Declare the dependency on `han-communication`.** The canonical rule and writing-voice profile live in [`han-communication/references/`](./han-communication/references/); no plugin vendors a copy. If the skill's plugin does not already depend on `han-communication`, add the direct dependency edge to its `plugin.json` so the capability resolves by qualified name. (`han-planning`, `han-linear`, and `han-feedback` host no prose-producing skill, so they carry no edge.) -2. **Embed the structural rules in the output template.** The skill's output template carries main-point-first, descriptive front-loaded headings, one-idea-per-paragraph, numbered lists for steps and bullets for the rest, and progressive disclosure, so the draft is born structured. -3. **Source the standard and apply it, with an audience frame.** The skill invokes `han-communication:readability-guidance` at its drafting point to surface the rule and writing-voice profile into its own context, then applies them while holding the audience frame: a capable reader who did not do the work. If the skill's real reader is a specific expert (an engineer, a pull-request reviewer, a non-technical stakeholder), name that reader instead of defaulting. Scope the frame per section so technical specifics the reader needs are not simplified away. -4. **Add the standardized self-check.** Before presenting, the skill runs six behaviorally-anchored yes/no criteria over the prose regions only: main point first, descriptive headings, one idea per paragraph, sentence length, no blocklisted word, every fact preserved. It corrects any failure. Leave code fences, diagram bodies, rendered markup, and citation identifiers unevaluated and unchanged. -5. **Wire the rewrite pass only if the skill synthesizes.** If the skill has a synthesis or editor step (a distinct pass, after the full draft exists, that reviews or consolidates the whole draft before presenting it), dispatch the [`readability-editor`](./docs/agents/han-communication/readability-editor.md) agent after the draft is written and before the self-check. It reads `han-communication`'s own canonical rule, so pass no rule path; it rewrites the draft, preserving every fact. Where the skill already ran a readability pass of its own, the dedicated reviewer replaces it rather than stacking a second pass on top. A synthesis skill that cannot dispatch an agent today gains that capability as part of wiring the standard in. - -Keep the applied set tight.

A single validation pass typically runs in a few minutes (scope-dependent). The agent is designed to run once per investigation or gap analysis, not iteratively.

One paragraph (read/write ratio, row-count projection, transactional vs analytical, regulated data in scope, availability and consistency targets) collapses whole classes of Open Questions and sharpens severity calls. -- **Point at the EXPLAIN plans you already have.** If you have captured `EXPLAIN ANALYZE` output, slow-query log excerpts, `pg_stat_statements` dumps, or APM traces for the hot queries in scope, drop them in the repo (or the prompt).

Open Questions from the first pass become Answered in the second. -- **Pair it with the security analyst on regulated changes.** The agent deliberately does not re-derive exploit paths. For a change touching auth, payments, or PHI / PCI data, dispatch `adversarial-security-analyst` alongside and compare the reports. -- **Pair it with the devops-engineer on migrations that touch production.** The data-engineer enforces expand-and-contract discipline at the schema level. `devops-engineer` enforces progressive-delivery discipline at the rollout level.

If something is not traceable, the agent is instructed to drop it. ## How to get the most out of it -- **Provide a production profile.** The single biggest lever. A one-paragraph statement of traffic shape, criticality tier, regulated data, and error-budget status collapses whole classes of Open Questions and sharpens severity calls. -- **Name the change class.** Tell the agent whether this is cosmetic, routine, or a schema/auth/payment tier change. The progressive-delivery and risk-stratification protocols calibrate on this. -- **Point at the runbook or ADR, if one exists.** The agent cannot `curl` Confluence or read private wikis, but it can read anything in the repo. Drop a copy of the relevant runbook or decision record into the project and reference it. -- **Say what ships when.** If a deadline is looming, ask the agent to sequence findings strictly into *"must-fix-before-rollout"* vs. *"track-and-improve."* It already does this, but an explicit reminder sharpens the P0/P1/P2 judgment. -- **Treat Open Questions as work.** They are not rhetorical.

Open Questions from the first pass become Answered in the second. -- **Pair it with the security analyst on regulated changes.** The agent deliberately does not re-derive exploit paths. For a change touching auth, payments, or PHI/PCI data, dispatch `adversarial-security-analyst` alongside and compare the reports. -- **Pair with a reviewer agent.** The agent generates findings.

The task is multi-dimensional synthesis across delivery performance, observability, security posture, scale, and cost. Avoid dispatching it in parallel for the same surface or in tight loops over every service in a monorepo. Scope tightly and it pays off. +The agent runs on `opus`.

A single review is slower and more expensive than a typical lookup agent, which is intentional. The task is multi-dimensional synthesis across the artifact, the codebase, standards documents, ADRs, and the question log, plus the judgment call of *which* questions would change the decision. Avoid dispatching it in parallel for the same artifact or in tight loops over every plan file in a repo. Scope tightly and it pays off. +The agent runs on `opus`.

Resolution is either *cite the missing evidence*, *replace with a strictly simpler version*, or *defer with a reopen-when trigger*. +The agent applies the **YAGNI Evidence Sweep** protocol when stress-testing a plan, design, or branch of code changes. +The generalist posture is well-suited to the rule.

The agent's Plain-Language Reframing protocol (Protocol 8) is the rubber duck applied to plans, designs, and standards documents. Restating the artifact in the thirty-second-whiteboard version often exposes the load-bearing jargon, the missing step, or the hidden assumption that the author could not see. +Andy Hunt and Dave Thomas introduced the "rubber duck" practice: explaining a problem out loud in plain language to +surface the gaps in your own reasoning.

Is there evidence the system needs this artifact *now*? Acceptable evidence: a named upstream finding the artifact resolves, an existing code path that breaks without it, three current concrete uses, a measured incident or workload, an applicable regulation. Recommendations that fail the evidence test are deferred as YAGNI candidates with a named reopening trigger (first real incident class observed, measured throughput crossing a threshold, third concurrent use of the helper, etc.). +The agent enforces a **Premature Operability Machinery** rule at the code level.

A single audit is slower and more expensive than a typical lookup agent, which is intentional. The task is multi-dimensional synthesis: the source code, the anti-pattern vocabulary, the named failure-mode catalog, the production-impact reasoning, the tone-anti-pattern sweep on the agent's own findings, and the sequenced remediation.

An outcome stated in one or two plain-language sentences collapses whole classes of open questions during Protocol 1. If the outcome is unclear, the agent will tell you. That is itself useful signal. -- **Name the specialists who should be in the room.** If you already know the plan touches UX, security, and DevOps, say so. The agent runs a round-robin against the specialists it knows about. Missing specialist context produces missing specialist participation records. -- **Point it at the standards library.** CLAUDE.md, ADRs, coding standards, and any project-discovery reference sharpen the inconsistency and standards-conflict check. When those are missing, the agent flags the missing library as a finding. Useful signal on its own. -- **Treat open questions as work.** Open questions are not rhetorical. Each one is something the team must answer (from a specialist, from evidence-gathering, from a stakeholder) before the plan can be fully trusted. The agent will not close an open question by inventing a plausible answer. -- **Use facilitation before synthesis.** Synthesis is only as strong as the facilitation inputs. If the discussion has not had round-robin facilitation, the synthesis will have gaps. Run facilitation mode first, then synthesis mode with the facilitation summary as input. -- **Dispatch the named specialists.** The PM's job is to coordinate, not to replace. When the facilitation summary names specialists to bring in (for example, *"devops-engineer to confirm rollout plan"*), dispatch those specialists before returning to synthesis. -- **Honor the "not needed" calls.** When the PM explicitly says a specialist is not needed on a plan, that is also a decision worth honoring. It frees the specialist's attention for work where their domain is touched. -- **Pair with a reviewer agent.** The PM generates the plan. It does not evaluate its own output. If you want adversarial validation of the synthesized plan, follow it with `adversarial-validator` or a `junior-developer` stress-test. See [multi-agent-economics.md](../../../han-plugin-builder/skills/guidance/references/agent-building-guidelines/multi-agent-economics.md) for why self-evaluation is a bad default. -- **Re-run after changes.** As specialists report back, open questions become answered questions, and the synthesis improves.

The agent is designed to be re-dispatched once new evidence has landed. ## Cost and latency -The agent runs on `opus`. A single facilitation or synthesis pass is slower and more expensive than a typical lookup agent, which is intentional. The task is multi-dimensional synthesis across specialist inputs, claim ledgers, RAID tracking, and standards libraries, plus the judgment call of *which* questions would change the decision and *which* specialists must be heard before the plan can commit. Avoid dispatching it in parallel for the same discussion or in tight loops over every planning conversation. Scope tightly and it pays off. +The agent runs on `opus`.

Scope tightly and it pays off. ## YAGNI -The agent applies the **YAGNI Evidence Gate** protocol during facilitation and synthesis. A discussion can commit many kinds of proposals: a plan step, abstraction, infrastructure addition, configuration knob, ADR, coding standard, test, or build phase. Each one must cite at least one piece of acceptable evidence that it is needed *now*. Uncited proposals are challenged in the discussion. If no evidence surfaces, they move to a `## Deferred (YAGNI)` section in the synthesized output with a named *reopen-when* trigger. The agent never silently drops a deferral. You always see the deferred item and the trigger that would justify reopening it, so the choice to keep or release the item stays conscious. +The agent applies the **YAGNI Evidence Gate** protocol during facilitation and synthesis.

The agent's round-robin protocol is taken directly from this practice. So is its insistence on hearing every relevant voice before decision, and its posture of driving ownership of a decision to the level where accountability sits. +The Project Management Institute publishes guidance on facilitative project management.

A single audit is slower and more expensive than a typical lookup agent, which is intentional. The task is multi-dimensional synthesis and judgment. Avoid dispatching it in parallel for the same surface or in tight loops over every file in a codebase. Scope tightly and it pays off. +The agent runs on `opus`.

The agent walks all 10 as a protocol and uses their names as the citable principle on findings (*"visibility of system status," "recognition rather than recall," "error prevention"*).

The agent uses this framework in its affordance audit and relies on it to push back on "flat" designs that strip signifiers for aesthetic reasons. The `Skeuomorphism Nostalgia` anti-pattern in the agent is directly derived from Norman's work and prevents arguing for physical-imitation ornament without affordance analysis. +Don Norman's distinction between affordances (action possibilities) and signifiers (perceptible cues that announce those +actions) explains why digital interfaces are harder to make usable than physical tools.

It decomposes that moment into four parts: trigger, rules, feedback, and loops/modes. The agent uses this framework inside its affordance protocol. Every meaningful interaction in the focus area can be audited for whether each of the four parts is present and discoverable. The `Microinteraction Silence` anti-pattern is derived directly from this framework and catches actions that mutate state without perceptible feedback. +Dan Saffer's _Microinteractions_ defines the unit of interaction design as a single contained moment (a toggle, a save, +a react, an undo).

The agent uses Cooper's framing to keep the Critical Inquiry protocol focused on goals and to reject findings that critique a feature without naming the goal it serves. This complements Jobs-to-Be-Done by adding a posture toward designing the interaction backward from the goal, not forward from available controls. +Alan Cooper's _About Face_ established goal-directed design: the practice of grounding interaction decisions in a user's +end goal rather than feature lists or technical capabilities.

The agent uses it to detect choice overload in menus, multi-action layouts, and modal *"what next?"* dialogs, and pairs it with progressive disclosure as a remediation pattern. This turns "cognitive load" into an evidence-based finding rather than a vague complaint. +The Hick–Hyman law states that decision time grows logarithmically with the number of choices.

The agent requires every audit to enumerate the persona spectrum it is scoping to (one-handed, low-bandwidth, second-language reading, assistive-tech use, cognitive fatigue). It flags `Persona of One` as an explicit anti-pattern when findings collapse the spectrum into a single ideal user. +Microsoft's toolkit reframes disability as a mismatch between a person and their environment and maps abilities across +permanent, temporary, and situational constraints.

A 2022 European Commission report found 97% of popular EU-facing sites used at least one. The agent scans consent, subscription, cancellation, delete, and permission flows for named classes (confirmshaming, roach motel, sneak into basket, misdirection, forced continuity, trick questions, privacy zuckering, nagging).

The rest of this page explains the plugins, the one dependency that surprises people, and how to pick. ## The plugins -Han ships as a family of plugins in one marketplace. `han-communication`, `han-core`, `han-planning`, `han-coding`, `han-github`, `han-reporting`, `han-feedback`, `han-atlassian`, `han-linear`, and `han-plugin-builder` carry components; `han` is a convenience wrapper that bundles `han-communication`, `han-core`, `han-planning`, `han-coding`, `han-github`, and `han-reporting`. - -- **`han-communication`.** The foundational plugin beneath every other. It owns the single canonical readability standard and writing-voice profile, the inline `readability-guidance` skill that surfaces them, the `edit-for-readability` skill, and the `readability-editor` agent. It depends on nothing; every plugin that produces prose output depends on it, so it comes along whenever you install one of them. -- **`han-core`.** The heart of the suite. It carries the research, analysis, and documentation skills, plus every agent the skills dispatch except the readability-editor (which lives in `han-communication`). If you install only this, you have the full set of specialists, but not the planning or coding skills. The planning skills (`/plan-a-feature`, `/plan-implementation`, `/plan-a-phased-build`, `/plan-work-items`, `/iterative-plan-review`) ship in `han-planning`, and the coding skills (`/code-review`, `/architectural-analysis`, `/investigate`, `/test-planning`, `/coding-standard`) ship in `han-coding`. See the [Skills Index](./skills/README.md) for the complete list. -- **`han-planning`.** The planning layer: the skills you reach for before implementation. It adds [`plan-a-feature`](./skills/han-planning/plan-a-feature.md), which builds a feature specification from scratch through an evidence-based interview; [`plan-implementation`](./skills/han-planning/plan-implementation.md), which turns a specification into an implementation plan through a project-manager-led team conversation; [`plan-a-phased-build`](./skills/han-planning/plan-a-phased-build.md), which splits a body of context into a sequence of independently demoable vertical-slice phases; [`plan-work-items`](./skills/han-planning/plan-work-items.md), which breaks a trusted plan into independently-grabbable, atomic work items; and [`iterative-plan-review`](./skills/han-planning/iterative-plan-review.md), which stress-tests an existing plan through codebase-grounded review passes. This plugin depends on `han-core` and is bundled by the `han` meta-plugin, so the bundled suite includes it; a core-only install does not. -- **`han-coding`.** The coding layer: the skills you reach for while working in code. It adds [`tdd`](./skills/han-coding/tdd.md), which drives a feature or behavior through a BDD-framed red-green-refactor loop and writes the tests and production code into your tree; [`refactor`](./skills/han-coding/refactor.md), which restructures existing code without changing its behavior through a test-gated refactoring loop; [`code-review`](./skills/han-coding/code-review.md), which runs a comprehensive review of the current branch or specified files; [`architectural-analysis`](./skills/han-coding/architectural-analysis.md), which assesses a module's coupling, data flow, concurrency, risk, and SOLID alignment; [`test-planning`](./skills/han-coding/test-planning.md), which produces a prioritized test plan; [`investigate`](./skills/han-coding/investigate.md), which runs an evidence-based root-cause investigation with adversarial validation of the fix; and [`coding-standard`](./skills/han-coding/coding-standard.md), which creates and updates coding standards. This plugin depends on `han-core` and `han-communication` and is bundled by the `han` meta-plugin, so the bundled suite includes it; a core-only install does not. -- **`han-github`.** The GitHub layer. It adds the skills that talk to GitHub through the `gh` CLI: [`post-code-review-to-pr`](./skills/han-github/post-code-review-to-pr.md), which posts a code review as comments on a pull request; [`update-pr-description`](./skills/han-github/update-pr-description.md), which writes a PR description from the branch's changes; and [`work-items-to-issues`](./skills/han-github/work-items-to-issues.md), which publishes a work-items file as GitHub issues. This plugin depends on `han-core` and `han-communication`. -- **`han-reporting`.** The reporting layer. It adds [`stakeholder-summary`](./skills/han-reporting/stakeholder-summary.md), which turns a feature specification into a plain-language stakeholder summary (also called an executive or business summary) with diagrams, for sharing with non-technical stakeholders before implementation kicks off; and [`html-summary`](./skills/han-reporting/html-summary.md), which converts that summary into a single self-contained HTML executive report. This plugin depends on `han-core` and `han-communication`. -- **`han-feedback`.** The feedback layer. It adds [`han-feedback`](./skills/han-feedback/han-feedback.md), which captures structured post-session feedback on the Han skills you ran and optionally posts it as a GitHub issue to testdouble/han. This plugin depends on `han-core`, but it is **opt-in**: the `han` meta-plugin does not pull it in, so you install it on its own. -- **`han-atlassian`.** The Atlassian layer. It adds [`markdown-to-confluence`](./skills/han-atlassian/markdown-to-confluence.md), which publishes a local Markdown file to a Confluence location you specify; [`project-documentation-to-confluence`](./skills/han-atlassian/project-documentation-to-confluence.md), which runs the core documentation skill and then publishes the result there; [`investigate-to-confluence`](./skills/han-atlassian/investigate-to-confluence.md), which runs the core investigate skill and then publishes the resulting investigation report there as a single page; [`code-overview-to-confluence`](./skills/han-atlassian/code-overview-to-confluence.md), which runs the core code-overview skill and then publishes the resulting overview there as a single page; [`plan-a-feature-to-confluence`](./skills/han-atlassian/plan-a-feature-to-confluence.md), which runs the `plan-a-feature` planning skill and then publishes the spec and its companion artifacts there as a page tree; and [`work-items-to-jira`](./skills/han-atlassian/work-items-to-jira.md), which creates one Jira ticket per slice from a work-items file. All work through the Atlassian MCP server. This plugin depends on `han-core`, `han-planning`, `han-coding`, and `han-communication`, because its wrapper skills run the core documentation skill, the `plan-a-feature` planning skill, and the `investigate` and `code-overview` coding skills respectively, and those prose-producing skills source the shared readability standard. It is **opt-in**: the `han` meta-plugin does not pull it in, so you install it on its own. It also requires a configured Atlassian MCP server. -- **`han-linear`.** The Linear layer. It adds [`work-items-to-linear`](./skills/han-linear/work-items-to-linear.md), which creates one Linear issue per slice from a work-items file in a single target team, resolving the team's real states, labels, Projects, and members before creating anything and linking within-file dependencies as native Linear "blocked by" relations. It works through the Linear MCP server. This plugin depends on `han-core`, but it is **opt-in**: the `han` meta-plugin does not pull it in, so you install it on its own. It also requires a configured Linear MCP server. -- **`han-plugin-builder`.** The plugin-building layer. It carries three skills: [`guidance`](./skills/han-plugin-builder/guidance.md), the authoring guidance for building Claude Code skills, agents, and plugins, which you can ask directly, or with `/guidance init` vendor into a repo along with the two builders (renamed with a `plugin-` prefix so they never collide with this plugin's own commands) plus a path-scoped rule set; [`skill-builder`](./skills/han-plugin-builder/skill-builder.md), which builds a new skill from scratch through an interview and a guidance-conformance review; and [`agent-builder`](./skills/han-plugin-builder/agent-builder.md), which does the same for a new agent. It is for people building plugins rather than shipping product features, so it is **opt-in** and depends on nothing: the `han` meta-plugin does not pull it in, and it does not bring `han-core` along. -- **`han`.** A meta-plugin with no components of its own. It exists to pull in `han-core`, `han-planning`, `han-coding`, `han-github`, and `han-reporting`. Installing it is how you ask for the bundled suite in one command. It does not bundle `han-feedback`, `han-atlassian`, `han-linear`, or `han-plugin-builder`. +Han ships as a family of plugins in one marketplace. `han-communication`, `han-core`, `han-planning`, `han-coding`, +`han-github`, `han-reporting`, `han-feedback`, `han-atlassian`, `han-linear`, and `han-plugin-builder` carry components; +`han` is a convenience wrapper that bundles `han-communication`, `han-core`, `han-planning`, `han-coding`, `han-github`, +and `han-reporting`. + +- **`han-communication`.** The foundational plugin beneath every other. It owns the single canonical readability + standard and writing-voice profile, the inline `readability-guidance` skill that surfaces them, the + `edit-for-readability` skill, and the `readability-editor` agent. It depends on nothing; every plugin that produces + prose output depends on it, so it comes along whenever you install one of them. +- **`han-core`.** The heart of the suite. It carries the research, analysis, and documentation skills, plus every agent + the skills dispatch except the readability-editor (which lives in `han-communication`). If you install only this, you + have the full set of specialists, but not the planning or coding skills. The planning skills (`/plan-a-feature`, + `/plan-implementation`, `/plan-a-phased-build`, `/plan-work-items`, `/iterative-plan-review`) ship in `han-planning`, + and the coding skills (`/code-review`, `/architectural-analysis`, `/investigate`, `/test-planning`, + `/coding-standard`) ship in `han-coding`. See the [Skills Index](./skills/README.md) for the complete list. +- **`han-planning`.** The planning layer: the skills you reach for before implementation. It adds + [`plan-a-feature`](./skills/han-planning/plan-a-feature.md), which builds a feature specification from scratch through + an evidence-based interview; [`plan-implementation`](./skills/han-planning/plan-implementation.md), which turns a + specification into an implementation plan through a project-manager-led team conversation; + [`plan-a-phased-build`](./skills/han-planning/plan-a-phased-build.md), which splits a body of context into a sequence + of independently demoable vertical-slice phases; [`plan-work-items`](./skills/han-planning/plan-work-items.md), which + breaks a trusted plan into independently-grabbable, atomic work items; and + [`iterative-plan-review`](./skills/han-planning/iterative-plan-review.md), which stress-tests an existing plan through + codebase-grounded review passes. This plugin depends on `han-core` and is bundled by the `han` meta-plugin, so the + bundled suite includes it; a core-only install does not. +- **`han-coding`.** The coding layer: the skills you reach for while working in code. It adds + [`tdd`](./skills/han-coding/tdd.md), which drives a feature or behavior through a BDD-framed red-green-refactor loop + and writes the tests and production code into your tree; [`refactor`](./skills/han-coding/refactor.md), which + restructures existing code without changing its behavior through a test-gated refactoring loop; + [`code-review`](./skills/han-coding/code-review.md), which runs a comprehensive review of the current branch or + specified files; [`architectural-analysis`](./skills/han-coding/architectural-analysis.md), which assesses a module's + coupling, data flow, concurrency, risk, and SOLID alignment; [`test-planning`](./skills/han-coding/test-planning.md), + which produces a prioritized test plan; [`investigate`](./skills/han-coding/investigate.md), which runs an + evidence-based root-cause investigation with adversarial validation of the fix; and + [`coding-standard`](./skills/han-coding/coding-standard.md), which creates and updates coding standards. This plugin + depends on `han-core` and `han-communication` and is bundled by the `han` meta-plugin, so the bundled suite includes + it; a core-only install does not. +- **`han-github`.** The GitHub layer. It adds the skills that talk to GitHub through the `gh` CLI: + [`post-code-review-to-pr`](./skills/han-github/post-code-review-to-pr.md), which posts a code review as comments on a + pull request; [`update-pr-description`](./skills/han-github/update-pr-description.md), which writes a PR description + from the branch's changes; and [`work-items-to-issues`](./skills/han-github/work-items-to-issues.md), which publishes + a work-items file as GitHub issues. This plugin depends on `han-core` and `han-communication`. +- **`han-reporting`.** The reporting layer. It adds + [`stakeholder-summary`](./skills/han-reporting/stakeholder-summary.md), which turns a feature specification into a + plain-language stakeholder summary (also called an executive or business summary) with diagrams, for sharing with + non-technical stakeholders before implementation kicks off; and + [`html-summary`](./skills/han-reporting/html-summary.md), which converts that summary into a single self-contained + HTML executive report. This plugin depends on `han-core` and `han-communication`. +- **`han-feedback`.** The feedback layer. It adds [`han-feedback`](./skills/han-feedback/han-feedback.md), which + captures structured post-session feedback on the Han skills you ran and optionally posts it as a GitHub issue to + testdouble/han. This plugin depends on `han-core`, but it is **opt-in**: the `han` meta-plugin does not pull it in, so + you install it on its own. +- **`han-atlassian`.** The Atlassian layer. It adds + [`markdown-to-confluence`](./skills/han-atlassian/markdown-to-confluence.md), which publishes a local Markdown file to + a Confluence location you specify; + [`project-documentation-to-confluence`](./skills/han-atlassian/project-documentation-to-confluence.md), which runs the + core documentation skill and then publishes the result there; + [`investigate-to-confluence`](./skills/han-atlassian/investigate-to-confluence.md), which runs the core investigate + skill and then publishes the resulting investigation report there as a single page; + [`code-overview-to-confluence`](./skills/han-atlassian/code-overview-to-confluence.md), which runs the core + code-overview skill and then publishes the resulting overview there as a single page; + [`plan-a-feature-to-confluence`](./skills/han-atlassian/plan-a-feature-to-confluence.md), which runs the + `plan-a-feature` planning skill and then publishes the spec and its companion artifacts there as a page tree; and + [`work-items-to-jira`](./skills/han-atlassian/work-items-to-jira.md), which creates one Jira ticket per slice from a + work-items file. All work through the Atlassian MCP server. This plugin depends on `han-core`, `han-planning`, + `han-coding`, and `han-communication`, because its wrapper skills run the core documentation skill, the + `plan-a-feature` planning skill, and the `investigate` and `code-overview` coding skills respectively, and those + prose-producing skills source the shared readability standard. It is **opt-in**: the `han` meta-plugin does not pull + it in, so you install it on its own. It also requires a configured Atlassian MCP server. +- **`han-linear`.** The Linear layer. It adds [`work-items-to-linear`](./skills/han-linear/work-items-to-linear.md), + which creates one Linear issue per slice from a work-items file in a single target team, resolving the team's real + states, labels, Projects, and members before creating anything and linking within-file dependencies as native Linear + "blocked by" relations.

Without an explicit posture on what counts as evidence and how confident to be in +it: -- Skills accept whatever the fastest-to-collect source said and treat the conclusion as settled, including conclusions that a second source would have contradicted. -- Agents conflate "the documentation says X" with "X is true," when the documentation may have drifted from what the system does today. -- Investigations rest on a single web search result and a plausible-sounding LLM rephrasing of it, with neither the search result nor the rephrasing held to a corroboration standard. -- Skills treat the absence of evidence as identical to the weakest tier of evidence and proceed anyway, when the honest move is to defer. +- Skills accept whatever the fastest-to-collect source said and treat the conclusion as settled, including conclusions + that a second source would have contradicted. +- Agents conflate "the documentation says X" with "X is true," when the documentation may have drifted from what the + system does today. +- Investigations rest on a single web search result and a plausible-sounding LLM rephrasing of it, with neither the + search result nor the rephrasing held to a corroboration standard. +- Skills treat the absence of evidence as identical to the weakest tier of evidence and proceed anyway, when the honest + move is to defer. -Evidence-based reasoning is not the same as scientific rigor.

That is the bar this page +sets. ## The three principles ### Principle 1: Proximity to origin -Evidence drawn from closer to the originating event or data carries more weight than evidence at greater remove. A reproducible failure observed in production carries more weight than a Stack Overflow answer that describes the same symptom. The current source code carries more weight than an architecture diagram from a year ago. A passing test that exercises the code path carries more weight than a docstring claiming the path works. +Evidence drawn from closer to the originating event or data carries more weight than evidence at greater remove. A +reproducible failure observed in production carries more weight than a Stack Overflow answer that describes the same +symptom. The current source code carries more weight than an architecture diagram from a year ago. A passing test that +exercises the code path carries more weight than a docstring claiming the path works. -Apply this as a heuristic, not as a ranked ladder. A numbered list of source types ("production observation > tests > codebase > commits > docs > blogs > LLM output") looks operational but breaks immediately at the first tier boundary. A passing test that does not exercise the failing input is not stronger evidence than a clearly-documented contract that says the input should work. The principle is real; the strict ordering it appears to imply is not. +Apply this as a heuristic, not as a ranked ladder.

A +passing test that does not exercise the failing input is not stronger evidence than a clearly-documented contract that +says the input should work. The principle is real; the strict ordering it appears to imply is not. Specifically, the proximity ordering inverts in three contexts: -- **Formal-methods or specification-compliance contexts.** When the specification is the authoritative artifact (an API contract, a state-machine definition, a regulatory schema), running code that diverges from the specification is a bug in the code, not new evidence about the system. The specification wins. -- **Regulatory or legal-compliance contexts.** When a regulation or contract names a required behavior, observed behavior that violates the requirement does not become the new requirement. The regulation wins. -- **Pre-incident observation of intended behavior.** A test that fails proves a bug exists. A test that passes proves the tested inputs behaved correctly for the tested code paths, and nothing more. Passing and failing tests are not symmetric evidence. +- **Formal-methods or specification-compliance contexts.** When the specification is the authoritative artifact (an API + contract, a state-machine definition, a regulatory schema), running code that diverges from the specification is a bug + in the code, not new evidence about the system.

Do not present "running code beats docs" as a rule that closes a discussion. Present it as the question that opens one. +When you cite this principle in a skill or an agent's output, name the source's distance from the origin and the +conditions you considered. Do not present "running code beats docs" as a rule that closes a discussion. Present it as +the question that opens one. ### Principle 2: Independent corroboration -A claim corroborated by two or more independent sources carries more weight than a claim resting on one source. This applies most sharply to web sources, which sit outside Han's trust boundary and have no built-in verification mechanism. A single Stack Overflow answer, a single blog post, a single arXiv pre-print, or a single LLM-generated explanation that drives a recommendation must be marked single-source. It cannot be the sole basis for the recommendation. +A claim corroborated by two or more independent sources carries more weight than a claim resting on one source.

It cannot be the sole basis for the recommendation. -The corroboration gate as written applies to web sources that bear on a recommendation. It does not apply to codebase evidence. A single file path at a specific line number is not weakened by being a single citation. The current source code is the current state of the system. Demanding a second independent code path to confirm a root cause would either be vacuously satisfied (the file path is the second source) or would reject valid single-file findings. +The corroboration gate as written applies to web sources that bear on a recommendation.

Record both, name the disagreement, and let the reader judge. Silently picking the source you agree with is the failure mode the gate is meant to prevent. +When sources contradict each other, surface the conflict.

Defer the dependent decision. Name the concrete trigger that would justify revisiting. +When a claim has no evidence at any tier, label it. Defer the dependent decision. Name the concrete trigger that would +justify revisiting. -The wrong response is to treat "no evidence" as identical to "very weak evidence" and proceed anyway. That collapses two distinct states into one and loses signal. A claim with very weak evidence still gives you something to test against. A claim with no evidence gives you nothing. Proceeding as if you had something is how cargo-culting takes root. +The wrong response is to treat "no evidence" as identical to "very weak evidence" and proceed anyway.

Record the claim, record why no evidence exists yet, record the concrete trigger that would justify revisiting, and move on to the next item that has evidence to work with. Real triggers are a measured metric, an incident that fires, a customer commitment, a regulation taking effect, or a dependency landing. Aspirational triggers ("when we have time to investigate") are not triggers. +The response Han uses is the same defer-with-trigger pattern [YAGNI](./yagni.md#the-deferred-yagni-section-format) uses. +Record the claim, record why no evidence exists yet, record the concrete trigger that would justify revisiting, and move +on to the next item that has evidence to work with.

The vocabulary lives at three levels: -- **Codebase** is the trusted current-state anchor. The current source code, the current tests, the current configuration, the current build output. When codebase evidence contradicts other evidence, surface the conflict explicitly and treat the codebase as authoritative on what the system does today. -- **Web** sits outside the trust boundary. Documentation pages, blog posts, Stack Overflow, GitHub issues, RFCs, vendor whitepapers, LLM-generated content. Web sources can be wrong, stale, adversarially shaped, or contextually misapplied.

The steps are grouped into named phases of three to four items each (occasionally up to six when a phase is a natural unit). Each phase is a natural pause point where you can stop and look at what you have. Decision points inside a step are written inline as "if X, do Y; otherwise, do Z" rather than as separate tracks. Each guide documents the **happy path** first and groups variations (different starting points, optional follow-ons) under a final **Variations** section.

Reach for the first to understand now and the second to remember later.

That grounding exists so you can verify, which the research says is the step that turns reading into understanding. Open the files the artifacts name. -- **Once a doc is referenced from `CLAUDE.md`, Claude reads it on its own.** The reference `/project-documentation` adds is not decoration. In later sessions, when Claude explores the codebase, it reads that doc as project context. So the understanding you captured flows into every future planning, review, and overview pass without you doing anything else. -- **Sizing is read from the target, not the prompt length.** `/code-overview` and `/architectural-analysis` classify the target and scale their agent rosters, defaulting to small and escalating only on a clear signal. Pass `small`, `medium`, or `large` as the first argument when you already know the target is bigger than the default.

Do not reopen the spec for something that is really an implementation detail, and do not patch a work item when the behavior underneath it actually moved. +The rule of thumb: change the document closest to the work item that still gets the change right.

Name the file you want to update and describe the change, and the skill revises the document rather than producing an unrelated one. For a behavioral change, that is `/plan-a-feature`; for an implementation change, `/plan-implementation`.

Answer the prompt, and note the filename if a new one was created so you point the next step at the right file. +2. **Expect to be asked how to apply the change.** The skills do not blindly clobber your existing work. + `/plan-implementation` asks whether to overwrite the existing plan or append iteration notes before it proceeds. + `/plan-work-items` (which you will reach in Phase 3) writes a date-suffixed file next to the original instead of + overwriting it, and tells you which file it wrote.

Phase 3 will help you catch + those across documents. ### Phase 3: Re-review and propagate the change -1. **Review the updated document for internal consistency.** A change in one place tends to leave a contradiction somewhere else: a step that now references a flow you removed, an assumption that no longer holds. Run [`/iterative-plan-review`](../skills/han-planning/iterative-plan-review.md) over the document you touched.

Without the discovery reference, the skill still tries, + but it is guessing at where your rules live. + +3. **Keep the rules current, and keep them relevant.** If the change lands a decision worth recording, capture it with + [`/architectural-decision-record`](../skills/han-core/architectural-decision-record.md). If it establishes a + convention the team will apply again, write it down with + [`/coding-standard`](../skills/han-coding/coding-standard.md). Both then feed every later review automatically. One + caution that the evidence is clear on: more context is not strictly better. The lever is the _right_ context, not all + of it. The single ticket that governs this change and the standards that govern the changed module help. Bulk-dumping + every loosely related doc into the prompt measurably hurts, because the model loses the relevant material in the + noise. Give the review the rules that apply to what changed, not your whole wiki. ### Phase 2: Run the review as a scoped job, not a generic one -Generic, un-scoped review is the noisy kind everyone complains about. It defaults to nit-picking because "review this" reads to the model as "produce comments", and absent a specific job, the comments it produces are low-value. The fix is specificity: tell the reviewer what to look for, against what rubric, and what to ignore. Han's review is built around this, so the happy path is short. - -1. **Run [`/code-review`](../skills/han-coding/code-review.md).** With no arguments, the skill classifies the change as small, medium, or large (defaulting to small) and dispatches a roster of specialist agents proportional to that size. Two always run: `junior-developer` for clarity and standards, `adversarial-security-analyst` for exploit-path security. The rest (`test-engineer`, `edge-case-explorer`, `structural-analyst`, `behavioral-analyst`, `concurrency-analyst`, `data-engineer`, `devops-engineer`, `on-call-engineer`) join only when the changed files touch their domain. Each one arrives with a narrow, scoped brief and a calibration directive. That directive tells it to raise only what the change introduced or worsened, plus anything critical regardless of who introduced it. That scoping is the whole reason the output is not a generic nit list. It is not the agent's persona label doing the work; naked "you are a senior engineer" framing does not reliably help and can hurt. It is the specific job each agent is given. - -2. **Add a focus hint when the change touches a load-bearing surface.** Auth, billing, a data migration, a public API contract. Name it in the prompt: - - > `/code-review` *"Focus on the security implications of the new auth endpoints."* - - The hint biases the manual file-by-file pass toward the area you named, while the parallel specialists still cover the full scope. A focused review of the surface that matters beats an evenly spread pass that gives the migration the same attention as a typo fix. - -3. **Override the size only when you know better than the auto-classification.** Pass `small`, `medium`, or `large` as the first positional argument: `/code-review large "focus on the new auth endpoints"`. A larger size raises the upper bound on the roster and widens the severity bands in scope; a smaller size prefers fewer agents producing higher-signal findings. Most of the time the default is right. Reach for the override when you know a three-file diff carries more risk than its size suggests, or when a large diff is mechanical and you want it kept quiet.

AI review catches real bugs a human pass misses. And AI review cannot replace the human; the human owns the output. The skill does a first pass of filtering for you so the noise is lower before you ever read it. Then it hands you a result to judge, not a verdict to rubber-stamp. - -1. **Read the Review Summary table and the Review Recommendation first.** These two sections are always present. The table indexes every corrective finding and every security finding by severity; the recommendation tells you whether the skill thinks the branch is mergeable as-is. Start there, then read the finding blocks the table points you to. By the time you see them, the findings have already passed through four filters: - - 1. A reachability gate that demotes findings whose own rationale leans on words like *theoretical* or *hypothetical*. - 2. The security agent's standard, which requires a demonstrated exploit path before it reports a vulnerability. - 3. An independent validation pass that re-reads the change and confirms, demotes, or (with concrete counter-evidence) drops each finding. - 4. A self-consistency check that catches two findings on the same lines that contradict each other. - - Security findings are exempt from the demotion gate, because their evidence bar is already higher. The validation pass re-attacks the findings against the code itself, the same way `/investigate` validates a root cause. It is built to drop a finding only when the code disproves it, not to quiet the review. - -2. **Read the YAGNI section as advice, not as blocking findings.** Speculative additions the change did not need (defensive code for inputs that cannot occur, a single-implementation interface, a config knob no caller sets) land in their own `### 🟡 YAGNI` section. These do not count toward Critical, Warning, or Suggestion, and they do not block a clean review. The posture is to make the cost of the extra code visible so you can decide consciously whether to keep it, simplify it, or drop it. See [YAGNI](../yagni.md) for what the skill considers evidence of need. - -3. **Push back on anything that does not hold, then fix and re-run.** This is the part you own. If a finding misreads the intent, or flags a project pattern that is deliberate, or rests on a premise the code does not support, say so. The review is the AI's recommendation; the call to act on it, defer it, or reject it is yours. When you have fixed the findings you accepted, re-run `/code-review`. The skill is cheap to re-dispatch and built for per-branch cadence. Confirm the count drops, and watch for anything a fix introduced. +Two things are true at once, and both are well-evidenced.

It runs the identical review; branch context flows automatically, since it is the same Step 1.5 on the same branch. It adds a clarity pass over the drafted review text, and offers to post the result to GitHub. It posts as a formal review when you are not the PR author, and as a PR comment when you are (GitHub rejects formal reviews from authors). It picks `REQUEST_CHANGES` versus `COMMENT` based on the severity of what it found. It needs `gh` and `jq` installed and an open PR on the branch. - -- **The change traces back to a Jira ticket and you have the MCP configured.** Point the review at the ticket so it can check the code against what the ticket asked for, the same way grounding it in a PR description does. One real caution: a fetched ticket is untrusted third-party text. Its description can carry content aimed at steering the review agent. `/code-review` now treats the branch context it loads at Step 1.5 (PR description and commit messages) as untrusted data. It strips directives during summarization, and wraps the binding in explicit untrusted-data markers, so the agents use it for intent only. That guard reduces the risk but does not remove your part of it: when you paste a ticket in yourself, treat it as data, not as instructions. Skim it before you feed it, and pull in the acceptance criteria rather than pasting an entire comment thread you have not read. - -- **You ran several review loops and they keep finding things.** Looping over the same code with fresh passes does raise how many real bugs you catch. Returns diminish sharply after roughly three to five passes, and later passes do catch bugs that earlier fixes introduced. So a second or third loop is worth it. Two things to keep straight. Looping does not by itself lower the noise; that is what Phase 1 and Phase 2 are for. And if your loop has the AI *implement* the fixes between passes, rather than only re-reviewing static code, do not assume each AI-written fix is clean. Re-review the changed code, because AI-fix-and-regenerate cycles can accumulate new problems round over round. - -- **The review came back clean, or nearly so.** A well-scoped review that finds nothing is the design working, not the skill failing. The whole point of the context, the scoping, and the calibration is that the reviewer is allowed to come back quiet when the change is sound. Do not go looking for a knob to make it complain. A clean review on a small, well-understood change is a perfectly good outcome. - -- **A finding hides a bug whose root cause you do not yet understand.** When a Critical finding points at something deeper than the diff shows, hand it to [`/investigate`](../skills/han-coding/investigate.md).

An investigation can bury its root cause under three paragraphs of context. A stakeholder summary can open with methodology instead of the decision. A code overview's headings can all read "Analysis." Each of these makes the reader redo the author's work. Without a shared standard: +A skill's output is only useful if the person who did not do the work can find, understand, and use it.

A code overview's headings can all read "Analysis." Each of these makes the reader redo the author's work. +Without a shared standard: - Each skill re-derives its own plain-language guidance, and the output reads differently from one skill to the next. - The main point lands wherever the drafting happened to leave it, not at the top. - Dense, technical deliverables get either unreadable or, worse, simplified until a load-bearing fact is lost. -The standard fixes the first two by naming the output properties once and applying them everywhere. It guards against the third by making fidelity outrank every readability move. +The standard fixes the first two by naming the output properties once and applying them everywhere.

The self-check flags any sentence past about thirty words as a candidate to split.

For example, a renamed plugin might reset to **v1.0.0** as the start of its new identity. The reset carries the effective weight of a major change, so subsequent changes on the same branch (new skills, bug fixes, removals) do not bump further; no change can escalate higher than the reset. +If a branch renames a plugin, splits one plugin into two, or otherwise resets a plugin's version baseline to a new +value, the reset **is** the branch's one bump.

Three rules govern how a release versions the suite: -1. **The parent always bumps on every release.** Every release is a release of the suite, so the parent `han` version increments even when only a single child changed. The parent's bump level matches the highest level across the whole release. If any bundled child has a major change, or a bundled child was removed from the parent's `dependencies`, the parent is major. If a bundled child has a minor change, or a brand-new bundled child plugin is introduced, the parent is at least minor. Otherwise, when only child patches or repo-level doc and config fixes occurred, the parent is patch. A change reaches the parent because anyone who installed the meta-plugin receives that child. An opt-in child the parent does not depend on, such as `han-feedback`, does not by itself force a parent minor or major bump, because installing `han` never delivers it. Its own changes still bump its own version line, and the release that introduces it still bumps the parent at least patch like any other release. - -2. **A child bumps only when its own directory changed.** Apply the major/minor/patch rules above to the changes inside that child's own directory (`han-core/`, `han-github/`, and so on). A child with no changes in a release keeps its version. Children version independently of each other: `han-github` going to `2.0.0` says nothing about `han-core`, which stays wherever its own changes put it. - -3. **A brand-new plugin is not bumped by the release that introduces it.** When a new `han-*` plugin first appears, the version in its `plugin.json` is its established baseline (normally `1.0.0`). It does not increment as part of the release that adds it. The introduction itself is the baseline, the same way a rename or reset (above) is its own branch's one bump. This is the general rule for every future extension, so the numbering for each new plugin starts consistently. - -Repo-root changes that do not live inside any plugin directory (`docs/`, `README.md`, `CONTRIBUTING.md`) are suite-level: they count toward the parent's bump level (normally patch) and never bump a child. +1. **The parent always bumps on every release.** Every release is a release of the suite, so the parent `han` version + increments even when only a single child changed.

The changelog records each changed plugin under its own sub-heading +with its new version. ### A note on per-plugin tags and version constraints -Claude Code resolves a *version-constrained* dependency (a `dependencies` entry that pins a semver range, like `{ "name": "han-core", "version": "~2.1.0" }`) using per-plugin git tags. These tags are named `{plugin-name}--v{version}`, for example `han-core--v2.1.0`. The `claude plugin tag --push` command creates these. Han does **not** need them today. Every dependency in `han`'s and `han-feedback`'s `plugin.json` is a bare string with no version range, so dependencies float to whatever the marketplace serves. The single suite tag `vX.Y.Z` is sufficient. If a future `han-*` plugin ever pins a dependency to a version range, the matching `{plugin-name}--v{version}` tags become required for resolution.

Each band caps the team or swarm size and the iteration depth. -- **Default is small.** Every sizing-aware skill starts the classification at **small** and only escalates to medium or large when concrete signals clearly require it. When a signal is borderline, the skill stays at the smaller band. -- **Auto-classified.** When you do not pass `$size`, the skill reads concrete signals: file count, subsystems touched, security/data/infra surface, and cross-cutting concerns. It announces the chosen size with a one-line justification before dispatching agents. -- **Always overridable.** Pass the size as the first positional argument when invoking the skill (`/code-review medium`, `/plan-a-feature small "describe the feature"`, and so on). The skill honors the override and still scales the team and round caps to the chosen size. -- **Conservative by design.** Fewer agents producing higher-signal findings is the goal; quantity is not the metric. The skill prefers under-dispatching that you can re-run at a larger size to over-dispatching that drowns you in low-signal findings. +- **Default is small.** Every sizing-aware skill starts the classification at **small** and only escalates to medium or + large when concrete signals clearly require it.

principles -- **Sizing is transparent.** The skill always announces the chosen band before dispatching agents. You can override, and the skill states the override explicitly. -- **Sizing is conservative.** Borderline signals drop to the smaller band. Over-dispatching is more expensive than under-dispatching when you can re-run a skill at a larger size. -- **Sizing is signal-driven.** The bands are defined by what the work touches, not by who asked for the review. The auto-classification is the same for everyone. -- **Sizing scales the team and the brief.** A larger size dispatches more agents *and* tells each agent that more severity bands are in scope and more findings are acceptable. A smaller size narrows both the roster and what each agent escalates. -- **Sizing is overridable, not configurable.** There is no project-level "always run as medium" setting. You opt in to the override on each invocation, when the auto-classification is wrong. +- **Sizing is transparent.** The skill always announces the chosen band before dispatching agents.

This file is the source content for Confluence and the thing you review before publishing. It lives in a scratch file, not your repo, so it does not get committed unless you move it there yourself. No code is changed. -- **The Confluence page.** A page created at, or updated in place at, the location you named, either as an unpublished draft (the default) or live, per your choice.

If you keep it local only at the confirmation step, you still keep the scratch-file draft; nothing is published. ## How to get the most out of it -- **Have the destination ready.** The fastest run is the one where you paste the page URL or name the space and parent up front, so the skill never has to stop and ask. -- **Use update mode for a living orientation page.** Point the skill at an existing page URL to keep a Confluence onboarding or architecture overview in sync as the code evolves, rather than creating a new page each pass. -- **Review the scratch-file draft before you publish.** The skill stops and shows you the file path on purpose.

The skill does not resolve the page tree here; it only confirms a location exists. -2. **Produce the overview to a scratch file.** Invoke `/code-overview` with all your context forwarded verbatim (the target, any size you gave, and the conversation context). `/code-overview` already writes to a scratch file and changes no code, so no extra instructions are needed.

This wrapper instructs it to stop at the report and change no code, because + the point is to publish the diagnosis, not to apply it. +- **The Atlassian MCP server is required.** The skill checks the server is connected before it runs any investigation, + so a missing server fails fast. If the server is missing or not authenticated, the skill stops and points you at + `/investigate` for a local-only run. It never silently falls back to local. +- **The report lands in `/tmp/` first.** Unlike `/investigate` on its own, this skill instructs the investigation run to + write to a `/tmp/` file rather than into your repo. That keeps the working report out of the repo until you decide to + publish it. +- **You review before publishing.** The skill shows you the `/tmp/` file path so you can open and read the report, then + asks how to publish. Nothing is posted until you choose. +- **You must provide the location.** The skill does not search Confluence for the right page. A real Confluence instance + is large and full of duplicate and similarly-named pages, so guessing the destination is unreliable. You name the + place; `/markdown-to-confluence` publishes there. +- **Confirmed publish, with a draft default.** Publishing puts the content where other people can see it, so the skill + waits for your choice before posting. You get three options: save it as a Confluence draft to edit and publish + yourself (the recommended default), publish it live immediately, or keep it local only. ## When to use it **Invoke when:** -- A bug or production incident has been investigated and the root-cause writeup needs to live in Confluence, where your team reads it, not only in the repo. +- A bug or production incident has been investigated and the root-cause writeup needs to live in Confluence, where your + team reads it, not only in the repo. - You want a diagnosis shared with stakeholders or on-call for review before anyone fixes the underlying problem. -- You already know the exact Confluence space or page where the report belongs and want it investigated and published in one pass. +- You already know the exact Confluence space or page where the report belongs and want it investigated and published in + one pass. **Do not invoke for:** -- **Local-only investigation.** Use [`/investigate`](../han-coding/investigate.md).

The publishing, the location resolution, and the create-or-update calls all belong to [`/markdown-to-confluence`](./markdown-to-confluence.md). This skill only validates its inputs, runs the planning skill to a temporary folder, lets you review the files, takes your publish choice, and hands each file to the publisher. -- **A plan is a set of files, so Confluence gets a page tree.** `/plan-a-feature` produces a primary `feature-specification.md` plus companion artifacts under `artifacts/` (the decision log, the team findings, and a lazily-created technical-notes file). This skill publishes the spec as a parent page and each companion artifact that exists as a child page beneath it. -- **It publishes in a single pass using title-based links.** The files link to each other with relative paths that break once each is a separate page. Because the skill decides every page's title up front, it rewrites those cross-file links into Confluence title-based page-link macros (``) before creating any page. Those macros resolve by title at view time, so no page URL has to exist first, and each page is created exactly once with no separate update pass. It drops the `#heading` fragment in the rewrite (see the limitation under "What you get back"). -- **The Atlassian MCP server is required.** The skill checks the server is connected before it produces any plan, so a missing server fails fast. If the server is missing or not authenticated, the skill stops and points you at `/plan-a-feature` for a local-only run. It never silently falls back to local. -- **The plan lands in `/tmp/` first.** Unlike `/plan-a-feature` on its own, this skill instructs the planning run to write its folder under `/tmp/` rather than into your repo's docs directory. That keeps the working plan out of the repo until you decide to publish it. Move it into the repo yourself if you want to keep it locally too. -- **You review before publishing.** The skill shows you the `/tmp/` file paths so you can open and read the spec and its artifacts, then asks how to publish. Nothing is posted until you choose. -- **You must provide the location.** The skill does not search Confluence for the right page. A real Confluence instance is large and full of duplicate and similarly-named pages, so guessing the destination is unreliable. You name the place for the spec; the artifacts become its children. -- **Confirmed publish, with a draft default.** Publishing puts the content where other people can see it, so the skill waits for your choice before posting. You get three options: save the pages as Confluence drafts to edit and publish yourself (the recommended default), publish them live immediately, or keep them local only.

These files are the source content for Confluence and the thing you review before publishing. They live in `/tmp/`, not your repo, so they do not get committed unless you move them there yourself. -- **The Confluence page tree.** The spec is posted as a parent page at the location you named.

Two things to know about how the content lands: -- **Cross-page links resolve by title, to the page, not the heading.** The spec's inline links to its artifacts (for example `([D4](artifacts/decision-log.md#...))`) are relative file paths that would not resolve once each file is its own Confluence page. The skill rewrites those links into title-based page-link macros that point at the correct Confluence child page by its title. It cannot preserve the `#heading` anchor, because Confluence Cloud generates its own heading anchors with a scheme that does not match the markdown slugs. As a result, a rewritten link lands you at the top of the right page rather than at the exact decision or note. Because the links resolve by title, renaming a published page in Confluence later may break the inbound cross-page links that point at it. Your local `/tmp/` originals keep their working relative links untouched. -- **Mermaid posts as source.** As [`/markdown-to-confluence`](./markdown-to-confluence.md) reports, Mermaid diagrams publish as fenced code blocks, not rendered diagrams, unless your space has a Mermaid macro. +- **Cross-page links resolve by title, to the page, not the heading.** The spec's inline links to its artifacts (for + example `([D4](artifacts/decision-log.md#...))`) are relative file paths that would not resolve once each file is its + own Confluence page.

If you keep it local only at the confirmation step, you still keep the `/tmp/` plan folder; nothing is published. ## If a publish fails partway -The tree is published in a single create pass. If one create call fails after others have already succeeded, the skill reports which file failed and its error, and names the pages it already created. Those already-created pages carry title-based links that point at the pages that did not get created, so those links dangle until the missing pages exist under their intended titles. Do not simply re-run the whole skill to recover: a re-run would re-create the pages that already succeeded, producing duplicate-title pages that break title resolution for the whole tree. Instead, create the missing page or pages by hand under their intended titles, or delete the partial tree in Confluence and publish again from clean. Your `/tmp/` originals are untouched either way. +The tree is published in a single create pass.

Your `/tmp/` originals are untouched either way. ## How to get the most out of it -- **Have the destination ready.** The fastest run is the one where you paste the page URL or name the space and parent up front, so the skill never has to stop and ask. -- **Review the `/tmp/` plan before you publish.** The skill stops and shows you the file paths on purpose. Open the spec and its artifacts, read them, and only then pick draft, live, or local-only. If they need changes, edit the `/tmp/` files (or re-run) before publishing. -- **Decide whether you want the plan in the repo too.** The plan lives in `/tmp/` by design. If you want a local copy under version control, move the folder into your repo's docs tree yourself, or run `/plan-a-feature` directly for a repo-resident plan and publish later with `/markdown-to-confluence`. -- **Know how diagrams and cross-links land.** Cross-file links are rewritten into title-based macros that resolve to the right Confluence pages, but land at the top of the target page rather than the exact decision or note. Mermaid diagrams post as source unless your space has a macro. Read the spec page knowing a decision link takes you to the Decision Log page, not straight to that decision's heading. Because the links resolve by title, avoid renaming the published pages if you want the cross-links to keep working. -- **Pair with `/plan-implementation` next.** Once the spec is settled, turn it into an implementation plan.

The plan it publishes is built by [`/plan-a-feature`](../han-planning/plan-a-feature.md), which applies the evidence-based [YAGNI](../../yagni.md) rule to every behavior, alternate flow, edge case, coordination, and open item before committing it to the spec. It records deferrals in the spec's `## Deferred (YAGNI)` section. Whatever YAGNI discipline shows up in the published spec comes from that run; this skill neither adds nor relaxes it. +This skill produces no artifact of its own, so it adds no YAGNI posture.

Its cost is whatever [`/plan-a-feature`](../han-planning/plan-a-feature.md) costs: its interview plus a review team of two to five `sonnet` sub-agents scaled by size, and a `project-manager` synthesis pass. On top of that, it costs the handful of fast Atlassian MCP calls [`/markdown-to-confluence`](./markdown-to-confluence.md) makes per page to resolve the location and publish. Because the cross-page links are rewritten into title macros before anything is created, each page is published with a single create call and no follow-up update. A spec with three artifacts is four create steps at the end. For a medium feature, expect the same shape and run time as `/plan-a-feature`, with the publish steps appended. +The skill itself dispatches no agents.

For a medium feature, expect +the same shape and run time as `/plan-a-feature`, with the publish steps appended. ## In more detail The skill walks a short, deterministic six-step process: -1. **Validate inputs.** Confirm the Atlassian MCP server is reachable (calling `getAccessibleAtlassianResources`), that the request names a feature to plan, and that a Confluence destination was provided. If the server is unavailable, stop before producing anything. If no destination was given, ask for one. The skill does not resolve the page tree here; it only confirms a location exists. -2. **Produce the plan to a temporary folder.** Invoke `/plan-a-feature` with all your context forwarded verbatim, plus one added instruction: write the output folder under `/tmp/` rather than the repo docs directory, and do not prompt for an output location. Capture the paths of every file written, including whether the lazily-created technical-notes file exists. -3. **Show the files for review.** Tell you the exact `/tmp/` paths so you can open and read the spec and its artifacts before deciding anything. -4. **Confirm the publish choice.** Ask how to publish the page tree: save as drafts (the recommended default), publish live, or keep them local only. If you keep them local only, the skill stops and reports the `/tmp/` folder. -5. **Rewrite cross-links to title macros, then publish the tree.** Decide every page's final title up front. Then rewrite each file's cross-file links into title-based page-link macros that point at the target page by its title, dropping the `#heading` fragment, and write the rewritten copies beside the untouched `/tmp/` originals. Then publish in a single create pass. Hand the spec to `/markdown-to-confluence` first, at the destination you named, and capture its page URL. Then publish each existing companion artifact as a child page under it, in the same mode. Each page is created exactly once. Report every page URL, that links resolve by title and land at the top of the target page, the rename caveat, and the Mermaid note. -6. **Verification.** Confirm inputs were validated and the plan was produced to `/tmp/`. Confirm the paths were shown for review and an explicit publish choice was obtained. Confirm the titles were decided up front and the cross-file links were rewritten into title macros. Confirm the tree was published in a single create pass with the originals left intact, and that everything was reported (or, if you declined, that only the `/tmp/` files exist). +1. **Validate inputs.** Confirm the Atlassian MCP server is reachable (calling `getAccessibleAtlassianResources`), that + the request names a feature to plan, and that a Confluence destination was provided.

This file is the source content for Confluence and the thing you review before publishing. It lives in `/tmp/`, not your repo, so it does not get committed unless you move it there yourself. -- **The Confluence page.** A page created at, or updated in place at, the location you named, either as an unpublished draft (the default) or live, per your choice. The skill reports the page URL on success and tells you which mode it used; for a draft, you still review and publish it yourself in Confluence.

Mermaid diagrams publish as Mermaid source + in code blocks (see below). If you keep it local only at the confirmation step, you still keep the `/tmp/` draft; nothing is published. ## How to get the most out of it -- **Have the destination ready.** The fastest run is the one where you paste the page URL or name the space and parent up front, so the skill never has to stop and ask. -- **Use update mode for living docs.** Point the skill at an existing page URL to keep a Confluence doc in sync with the code over time, rather than creating a new page each pass. -- **Review the `/tmp/` draft before you publish.** The skill stops and shows you the file path on purpose. Open it, read it, and only then pick draft, live, or local-only. If it needs changes, edit the `/tmp/` file (or re-run) before publishing. -- **Know how diagrams land.** `/project-documentation` writes diagrams as Mermaid in fenced code blocks. Confluence does not render Mermaid without a macro, so the blocks post as source. If your space has a Mermaid macro, they may render; otherwise they read as code. `/markdown-to-confluence` leaves them intact and tells you they posted as source. -- **Run `/project-discovery` first.** As with `/project-documentation`, the discovery reference helps the skill find the docs directory and align code-fence languages with the project's stack. +- **Have the destination ready.** The fastest run is the one where you paste the page URL or name the space and parent + up front, so the skill never has to stop and ask. +- **Use update mode for living docs.** Point the skill at an existing page URL to keep a Confluence doc in sync with the + code over time, rather than creating a new page each pass. +- **Review the `/tmp/` draft before you publish.** The skill stops and shows you the file path on purpose.

Its cost is whatever [`/project-documentation`](../han-core/project-documentation.md) costs: two to three `codebase-explorer` agents in parallel, one `content-auditor` in update mode, and one `information-architect` before verification, all on their default models. On top of that, it costs the handful of fast Atlassian MCP calls [`/markdown-to-confluence`](./markdown-to-confluence.md) makes to resolve the location and publish the page. For a medium feature, expect a few minutes total, the same shape as `/project-documentation`, with a short publish step at the end. +The skill itself dispatches no agents.

If the server is unavailable, stop before generating anything. If no destination was given, ask for one. The skill does not resolve the page tree here; it only confirms a location exists. -2. **Produce the documentation to a temporary file.** Invoke `/project-documentation` with all your context forwarded verbatim, plus one added instruction: write the result to a `/tmp/` file rather than the repo docs directory. Capture that path. -3. **Show the file for review.** Tell you the exact `/tmp/` path so you can open and read the draft before deciding anything. -4. **Confirm the publish choice.** Ask how to publish: save as a draft (the recommended default), publish live, or keep it local only. If you keep it local only, the skill stops and reports the `/tmp/` path. -5. **Publish with `/markdown-to-confluence`.** Hand the `/tmp/` file path, the Confluence destination, and your chosen publish mode to [`/markdown-to-confluence`](./markdown-to-confluence.md), which resolves the location, posts the page, and reports its URL. +1. **Validate inputs.** Confirm the Atlassian MCP server is reachable (calling `getAccessibleAtlassianResources`), that + the request names something to document, and that a Confluence destination was provided.

Unlike the GitHub sibling, this skill does not split work across repos. If the source file spans several code repos, the repo prose is informational only; it never changes which project a ticket lands in. -- **The Atlassian MCP server is required.** The skill checks the server is connected before it does any work. If the server is missing or not authenticated, the skill stops. It drives Jira entirely through the MCP server; there is no `gh`-style CLI and no shell-script pipeline. -- **Sensible Jira defaults, all overridable.** Each ticket is created as a **Story**, **unassigned**, in the project's **Backlog**, with the **reporter** taken from the authenticated Atlassian MCP identity. You can override the issue type, set an assignee, name a target column, and parent every ticket under an epic or a story. -- **Parenting is optional, and the parent decides the child type.** Pass `--parent ` to parent every created ticket. Name an **epic** and each item is a standard issue (Story by default) under the epic. Name a **story** (any standard issue) and each item is a **subtask** under the story, defaulting to the project's subtask issue type. You cannot parent under a subtask. Leave `--parent` out and tickets sit at the project's top level. `--epic ` is a deprecated alias for `--parent`. If a company-managed Jira project rejects parenting an item under an epic, the skill surfaces the project's legacy "Epic Link" field requirement rather than dropping the parent silently. -- **Within-file dependencies.** Every SYM named in a `Depends on` line must resolve to another slice in the same file. After all tickets exist, the skill records each dependency in the dependent ticket by rewriting its `Depends on` line to the blockers' Jira keys. It also creates a native "is blocked by" link when the configured MCP exposes an issue-link capability. -- **Reference artifacts, not process artifacts.** Every ticket description carries the artifacts an implementer needs: API and event contracts, design references, schema docs, ADRs, coding standards. It never carries the process artifacts that only record how the plan was reached, such as iteration histories, decision logs, or review findings. The full include and exclude lists live in [the reference artifact inventory](../../../han-atlassian/skills/work-items-to-jira/references/reference-artifact-inventory.md). -- **No screenshot embedding.** The GitHub sibling copies PNGs into the target code repo and embeds same-repo URLs. That mechanism is GitHub-specific and is not part of this skill. Design references are carried as links in the ticket; add image attachments in Jira by hand if a ticket needs them. -- **Evidence-based repair.** When a format check fails, the skill proposes a fix backed by a concrete source (a file path with line number, a plan section, an ADR ID) and lets you continue with the fills, correct them, or stop. -- **Idempotent resume.** After a ticket is created, its slice heading in the source file is annotated with the Jira key. A re-run skips already-annotated slices, so a partial run resumes cleanly. +- **One project, not a repo map.** Every work item becomes a ticket in the single Jira project you name.

The work-items file is an already-committed decomposition, and this skill publishes it without adding new behavioral commitments or speculative infrastructure. The closest thing to a gate here is the reference-artifact rule: ticket descriptions carry the contracts, designs, and standards an implementer needs and leave out the process artifacts that only record how the plan was reached. That is content hygiene, not YAGNI. +YAGNI does not gate this skill's output.

Its work runs in the conversation context: a handful of Atlassian MCP calls to preflight and resolve the target, the format validation with evidence-based repair, one `createJiraIssue` call per item, an `editJiraIssue` (and optional native link) per dependency, and an optional transition per ticket when a column is named. The most time-consuming runs are large work-items files, because ticket creation is one call per item. The skill is built for a once-per-breakdown cadence, and the heading annotations mean a re-run after an interruption only creates the tickets that remain. +The skill dispatches no agents.

A small run is the spine of four agents (`structural-analyst` and `behavioral-analyst` in parallel, then `risk-analyst`, then `software-architect`), plus `concurrency-analyst` when concurrency is present. A large run can reach nine agents. The discovery wave runs in parallel; `risk-analyst` runs next consuming the `S`/`B`/`C` findings; `software-architect` (and `system-architect` when on the roster) run last consuming all upstream output. `software-architect` and `system-architect` run on Opus; the discovery and risk analysts run on Sonnet. After synthesis, one `han-communication:readability-editor` rewrites the report's synthesized prose (the Executive Summary, the "How to Read" frame, and the section prefaces) against the readability standard, leaving each analysis section's verbatim agent output unchanged. For a medium-size module (a few thousand lines), expect a few minutes for the parallel pass plus sequential time for risk and synthesis. The skill is built for infrequent high-signal runs (refactoring decisions, architectural check-ins, pre-rewrite baselines), not for tight-loop iteration. It is a single fan-out / fan-in pass with no iteration round. If a band proves too small, re-run at a larger size. +The skill dispatches a variable roster.

Confirm the focus area resolves to real files and identify its boundary. Read CLAUDE.md / project-discovery.md for conventions. Note git availability. If the focus area does not resolve, stop and ask you to clarify. -2. **Detect signals and classify size.** Grep and Glob the focus area for concurrency, security, data, DevOps, and system-seam signals. Default to small and escalate only on clear higher-band signals. A passed `$size` overrides the classification but not the signal-based specialist selection. -3. **Build the roster and announce it.** Assemble the spine plus the signalled specialists within the band cap, and state the size, roster, and per-specialist justification in one line before dispatching. The analysis is read-only, so there is no blocking gate. -4. **Dispatch the discovery wave in parallel.** `structural-analyst`, `behavioral-analyst`, and any signalled discovery specialists run concurrently. Each receives a brief carrying the focus area, the driving concern, project conventions, git availability, and a size-scoped calibration directive. -5. **Compile the discovery findings.** Collect verbatim output from every discovery agent, preserving every numbered item and prefix. A "no concurrency patterns found" result is kept verbatim. -6. **Dispatch the risk analyst.** Pass `risk-analyst` the verbatim `S`/`B`/`C` findings (its documented input contract). It produces `R#` items cross-referencing the upstream findings. -7. **Dispatch the synthesis architects.** `software-architect` always runs, consuming all discovery output plus the `R#` items. `system-architect` runs only when it is on the roster, consuming the same plus the DevOps and data findings as its documented optional inputs. -8. **Render and present the report.** Read the template, fill it, and drop the sections whose agent was not dispatched.

Everything else (what it does, how it works, where to start) flows out of that, so you can get up to speed before working on or reviewing it. -- **When to use it.** You have landed in code you do not know, or a PR you are about to review, and you want a fast orientation before you start. -- **What you get back.** A scratch overview file (written outside the repository) with a purpose statement, Mermaid flow charts, the directly-related context, and where to start, all at minimal technical depth. -- **Size-aware.** The skill classifies the target as small / medium / large, defaults to small, and scales how many `codebase-explorer` agents it dispatches.

Pass the size as the first positional argument to override + (`/code-overview medium`). See [Sizing](../../sizing.md). ## Key concepts -- **Why first.** The overview is built to answer one question before any other: *why does this code exist?* The answer is the real problem it solves or the goal it accomplishes for the business or a user, not the technical mechanics. What it does, how it flows, and where to start are not dropped; they flow out of the why and exist to give you the context to understand it. A confidently stated why that the code's intent does not support is the one thing the skill guards hardest against. -- **Two modes.** *Code mode* explains a file, directory, or symbol as it is now: why it exists, then what it does. *PR mode* explains a set of changes: why they exist, grouped by the intent each group serves, and how to look at the PR before reviewing it. The skill picks the mode from the target. -- **Understand now, not document for later.** The overview is an ephemeral orientation aid written to a scratch file, never committed into the repository's documentation tree. That is the line against `/project-documentation`. -- **No findings.** The overview raises no quality findings, severities, or recommended changes. Even the PR-mode "what to watch" section is navigational: it names where the change is hardest to follow, not whether it is any good. That is the line against `/code-review`. -- **Accurate, not only readable.** Before you see it, an `adversarial-validator` pass re-reads the code and challenges every claim the draft makes, so the flow charts, entry points, and change groupings reflect what the code does. The validation guards truth (the description matches the code); it never crosses into judging the code's quality, which stays `/code-review`'s job. -- **Progressive disclosure, anchored on the why.** The most important understanding comes first: *why the code exists*, the problem it solves or goal it serves. Then comes the flow chart, then context, then where to start, each flowing from and serving that why. A reader who stops early still knows why the target exists and what need it meets. -- **Minimal technical detail, scoped per section.** The why, flow, and context stay high-level: the why is told as a problem solved or goal met, not technical mechanics. The where-to-start section is the exception, and names concrete entry points so you can open the right file. +- **Why first.** The overview is built to answer one question before any other: _why does this code exist?_ The answer + is the real problem it solves or the goal it accomplishes for the business or a user, not the technical mechanics. + What it does, how it flows, and where to start are not dropped; they flow out of the why and exist to give you the + context to understand it.

It classifies the target and scales the exploration roster: -| Size | Typical target | Explorers dispatched | -|---|---|---| -| **Small** *(default)* | A single file, a single symbol, or a small change set | 1 | -| **Medium** | A directory or module, or a moderate change set across one or two subsystems | 2–3 | -| **Large** | Multiple subsystems, or a large change set | 3–5 | +| Size | Typical target | Explorers dispatched | +| --------------------- | ---------------------------------------------------------------------------- | -------------------- | +| **Small** _(default)_ | A single file, a single symbol, or a small change set | 1 | +| **Medium** | A directory or module, or a moderate change set across one or two subsystems | 2–3 | +| **Large** | Multiple subsystems, or a large change set | 3–5 | -Classification defaults to small and escalates only on a clear signal; a borderline target stays at the smaller band. Pass `small`, `medium`, or `large` as the first positional argument to override. The roster is intentionally lean, `codebase-explorer` agents only, because this is read-only orientation, not the multi-specialist audit that `/code-review` and `/architectural-analysis` run.

The skill applies the accuracy corrections and the rewrite. The most expensive single step is the parallel exploration wave at large size. It is built for quick, on-demand orientation, so it is cheap at small size and safe to run often; it is read-only and re-runnable, so there is no approval gate before it works. +The skill runs on the default model tier and dispatches a lean roster: one to five `han-core:codebase-explorer` agents +in parallel, scaled to size, then a synthesis pass the skill performs itself, then two review passes in order: +`adversarial-validator` (accuracy, re-reading the code) first, then `han-communication:readability-editor` (a +readability rewrite of the corrected draft, preserving every fact).

Pass the size as the first positional argument to override (`/code-review medium`). See + [Sizing](../../sizing.md) for the full model. ## Key concepts -- **Three severity levels.** CRIT (must fix before merge: security, data corruption, breaking API), WARN (should fix: bugs, missing error handling, missing tests), SUGG (consider: style, refactoring, docs). Severity calibration is governed by Step 3.3 in the skill body, the authoritative home for size-based demotion. Manual findings (Steps 4 to 6) and agent findings (Step 7) follow the same rules: small changes escalate only Critical and prefer the lower severity on uncertainty; medium escalates Critical and Warning; large prefers the higher severity when in doubt. -- **Three review modes.** Mode A uses the full git branch diff. Mode B reviews uncommitted work when no branch diff exists. Mode C reviews specified files when git is absent. **In Mode B and Mode C the YAGNI checklist is skipped unless explicitly requested**, because no diff exists to distinguish introduced code from pre-existing code. -- **Size-aware agent dispatch.** Two agents always run on every review (`junior-developer` for clarity and standards, `adversarial-security-analyst` for exploit-path security). The rest of the roster (`test-engineer`, `edge-case-explorer`, `structural-analyst`, `behavioral-analyst`, `concurrency-analyst`, `data-engineer`, `devops-engineer`, `on-call-engineer`) is dispatched conditionally based on what the changed files touch. Larger sizes raise the upper bound on the roster; smaller sizes prefer fewer agents producing higher-signal findings. See the [Sizing](#sizing) section below. -- **Calibration directive.** Every dispatched agent receives a calibration directive that requires findings to be either introduced or worsened by the change, or critical irrespective of who introduced it. Theoretical concerns, pre-existing best-practice gaps, and benign-outcome scaling worries are excluded. Severity scales with size: small change → only Critical findings escalate; medium → Critical and Warning; large → all severities. -- **Per-agent dispatcher tailoring.** When `/code-review` dispatches `structural-analyst` and `behavioral-analyst`, it appends a default-SUGG directive so those agents start at the lowest severity and escalate only when the change introduces or worsens the issue. When it dispatches `junior-developer` and `edge-case-explorer`, it appends a file-list scoping directive so findings concern code on the scoped file list (with a narrower wording for `edge-case-explorer` that preserves its caller-read protocol while keeping the failure-mode target on the file list). These directives are `/code-review`'s tailoring; the agents' default behavior in other skills is unchanged. -- **Reachability phrase-match gate (Step 7.2).** When an agent's own rationale contains phrases like *theoretical*, *hypothetical*, *defense-in-depth*, *effectively impossible*, *in case the upstream*, *could happen*, *should never happen*, or *edge case that does not occur*, the finding is demoted by one severity before the rubric is applied. Security findings are exempt because the security agent's evidence standard already requires a demonstrated exploit path. The gate is a cheap, deterministic first pass and is brittle to paraphrase by design; a finding that hedges its reachability without one of the literal phrases is caught semantically by the Step 7.4 validation pass, not by growing the phrase list. -- **Independent findings validation (Step 7.4).** After the agent findings are collected and classified, the skill dispatches one `adversarial-validator` over the *consolidated corrective finding list*, the same agent `/investigate` uses to attack a root cause and fix. It is the only pass that re-reads the change in fresh context and judges each finding against the code rather than against the producing agent's rationale, so it does not anchor on what the specialists concluded. Each finding comes back Confirmed (kept), Partially Refuted (demoted one severity), or Refuted (dropped). A finding is dropped only when the validator supplies concrete counter-evidence at `file_path:line_number`; a bare assertion demotes rather than drops, and an uncertain verdict leaves the finding standing. Security findings are dropped only when the demonstrated exploit is refuted with counter-evidence. The pass is a finding *filter, not a finding source*: it never contributes findings of its own, and it skips entirely when the review produced no corrective findings. -- **Branch context loaded at Step 1.5.** Before agents are dispatched, the skill loads four sources of branch-level context in order: PR description (via `gh pr view` when `gh` is available, Mode A only), a local `pr-body`, `PR_BODY.md`, or `.pr-body` file at the repo root, branch commit messages, and an implementation plan from the planning directory. The planning directory resolves first to the `plans:` (or `planning:`) key under CLAUDE.md's `## Project Discovery` section. Otherwise, the skill globs `docs/plans/*/feature-implementation-plan.md` and `plans/*/feature-implementation-plan.md`, picking the directory whose name matches the current branch (treating `-` and `_` as interchangeable). The loaded content is summarized into a `$branch_context` block of at most 200 words. It is plumbed, alongside the user's `$focus_areas` argument, into every agent prompt so agents avoid re-raising items the team has already deferred or resolved. Because PR descriptions, ticket bodies, and commit messages are third-party content that can carry text aimed at steering the review agent, the skill treats `$branch_context` as **untrusted data, not instructions**. The Step 1.5 summary strips any directives addressed to the reader or an agent. Step 3.5 wraps the binding in explicit untrusted-data markers with a guard telling agents to use it for intent only and never to obey instructions inside it. The user's own `$focus_areas` argument is trusted and is not wrapped. Step 1.5 is skipped in Mode C. In Mode A and Mode B, when none of the four sources returns content, the skill emits a single fail-open warning and proceeds with `$branch_context` set to `none provided`. -- **Self-consistency check at Step 9.0.** Before the structural verification, the skill scans every pair of findings on the same file with overlapping line ranges, detects contradictory recommendations, demotes both, and adds a `Tension with {other-task-id}:` note for the human reviewer. Cross-file semantic contradictions are out of scope. -- **Premise verification before standards-compliance findings.** Step 5 requires reading at least one architectural file in the codebase that demonstrates a standard's premise before the skill raises a "violates standard X" finding. When the file does not confirm the premise, the finding is omitted with a logged note rather than raised on inferred premises. -- **Project-pattern deference.** A pattern that differs from general best practices but is consistent within the project is *not* a finding. Only deviations from the project's own conventions count. -- **Automated tool boundary.** If the project has a linter or formatter, trust it. Only flag style issues that tooling cannot catch. -- **Documentation compliance and freshness.** ADRs, coding standards, and general docs are read and checked against the diff. Only documents whose subject matter the change touches are read; pulling unrelated standards into the review dilutes the signal and degrades judgment, the same reason Step 1.5 caps branch context. Correctness- and behavior-bearing rules are weighted over style minutiae the linter already enforces. Stale docs that misdescribe current behavior become CRIT findings. +- **Three severity levels.** CRIT (must fix before merge: security, data corruption, breaking API), WARN (should fix: + bugs, missing error handling, missing tests), SUGG (consider: style, refactoring, docs). Severity calibration is + governed by Step 3.3 in the skill body, the authoritative home for size-based demotion. Manual findings (Steps 4 to 6) + and agent findings (Step 7) follow the same rules: small changes escalate only Critical and prefer the lower severity + on uncertainty; medium escalates Critical and Warning; large prefers the higher severity when in doubt. +- **Three review modes.** Mode A uses the full git branch diff. Mode B reviews uncommitted work when no branch diff + exists. Mode C reviews specified files when git is absent. **In Mode B and Mode C the YAGNI checklist is skipped + unless explicitly requested**, because no diff exists to distinguish introduced code from pre-existing code. +- **Size-aware agent dispatch.** Two agents always run on every review (`junior-developer` for clarity and standards, + `adversarial-security-analyst` for exploit-path security). The rest of the roster (`test-engineer`, + `edge-case-explorer`, `structural-analyst`, `behavioral-analyst`, `concurrency-analyst`, `data-engineer`, + `devops-engineer`, `on-call-engineer`) is dispatched conditionally based on what the changed files touch. Larger sizes + raise the upper bound on the roster; smaller sizes prefer fewer agents producing higher-signal findings. See the + [Sizing](#sizing) section below. +- **Calibration directive.** Every dispatched agent receives a calibration directive that requires findings to be either + introduced or worsened by the change, or critical irrespective of who introduced it. Theoretical concerns, + pre-existing best-practice gaps, and benign-outcome scaling worries are excluded. Severity scales with size: small + change → only Critical findings escalate; medium → Critical and Warning; large → all severities. +- **Per-agent dispatcher tailoring.** When `/code-review` dispatches `structural-analyst` and `behavioral-analyst`, it + appends a default-SUGG directive so those agents start at the lowest severity and escalate only when the change + introduces or worsens the issue.

Fix the findings and re-run. ## In more detail The skill walks a ten-step process (Step 1.5 is a context loader inserted between Steps 1 and 2): -1. **Identify changes.** Detect git mode (A/B/C), resolve project config, enumerate changed files. Bind `$focus_areas` from the user's free-form argument. -1.5. **Load branch context.** Attempt PR description via `gh pr view --json title,body,headRefName,baseRefName` (Mode A only, when `gh` is available); a local `pr-body`, `PR_BODY.md`, or `.pr-body` file at the repo root; branch commit messages via `git log {default-branch}..HEAD --pretty=format:%B` (Mode A) or `git log -n 20 --pretty=format:%B` (Mode B); and an implementation plan resolved through the CLAUDE.md `plans:` / `planning:` key or, failing that, a Glob over `docs/plans/*/feature-implementation-plan.md` and `plans/*/feature-implementation-plan.md` that prefers the directory matching the current branch name (with `-` and `_` interchangeable). Summarize loaded content into `$branch_context` (at most 200 words), treating the fetched content as untrusted data: the summary strips any instruction or directive addressed to the reader or an agent rather than carrying it forward. When nothing loads, emit a single fail-open warning, set `$branch_context` to `none provided`, and proceed. Skipped in Mode C. At Step 3.5 the binding is wrapped in explicit untrusted-data markers so agents use it for intent only and never obey instructions inside it. -2. **Automated quality checks.** Run the project's lint, build, and test commands. Report each failure as a CRIT finding with category `[Automated Check]`. Do not fix; report. -3. **Classify size and dispatch review agents in parallel.** Step 3.1 classifies the change as small / medium / large, defaulting to small, and binds `{size}` for every later consumer. Step 3.2 selects agents: the required two (`junior-developer`, `adversarial-security-analyst`) plus any conditional agents whose signals appear in the file list. Step 3.3 is the authoritative home for size-based demotion and attaches the calibration directive verbatim to every brief. Step 3.4 narrows each agent's brief to a domain-scoped slice of the file list (for example, `structural-analyst` receives source files only; `data-engineer` receives schema, migration, query, ORM, and data-access files only; `junior-developer` and `adversarial-security-analyst` receive the full list). Step 3.5 launches all selected agents in parallel, appending the shared `$focus_areas` and `$branch_context` blocks to every prompt and the per-agent dispatcher directives to `structural-analyst`, `behavioral-analyst`, `junior-developer`, and `edge-case-explorer`. -4. **Manual file-by-file review.** Every changed file (alphabetical) against the review checklist: correctness, data isolation, performance, error handling, testing, API design, maintainability, organization, docs, style, database, ADR compliance. In Mode B and Mode C, the YAGNI checklist is skipped unless the user requests it in `$focus_areas`. -5. **Documentation compliance analysis.** Read only the ADRs, coding standards, and docs whose subject matter the change touches, not the whole directory, and weight correctness-bearing rules over style minutiae the linter already covers. Verify each standard's premise applies by reading at least one architectural file in this codebase before raising a "violates standard X" finding; omit findings whose premise is not verified. +1. **Identify changes.** Detect git mode (A/B/C), resolve project config, enumerate changed files.

Junior-developer findings that overlap with a specialist's finding reference the specialist instead of duplicating. 7.4 dispatches one `adversarial-validator` over the consolidated corrective finding list to confirm, demote, or (with concrete counter-evidence) drop each finding; it runs whenever any corrective finding exists, even when no agents were dispatched, and skips when the review is clean. -8. **Generate review output.** Assemble the final review using the review template, rendering each section only when it has content and keeping the fixed section order. -9. **Verify.** Step 9.0 runs the self-consistency check (extract `{task-id, file-path, line-range, recommended-action-summary}` tuples, then compare overlapping pairs and demote contradictory recommendations with a `Tension with {other-task-id}:` note). Step 9.1 then verifies task IDs are sequential, `file_path:line_number` references are valid, exploit fields are populated for security findings, the summary table indexes every corrective and security finding (with security tiers shown inline) and matches the sections present, no section is rendered empty, security findings carry no Critical cross-reference while the recommendation still reflects their severity, and the YAGNI section's verbatim opening is preserved. +7. **Collect, classify, and validate findings in four sub-steps.** 7.1 reads each dispatched agent's output file. 7.2 + applies the reachability phrase-match demotion gate (CRIT → WARN → SUGG → omitted) when a finding's rationale + contains a documented reachability phrase; security findings are exempt. 7.3 classifies the surviving findings using + the size-aware rubric in `agent-finding-classification.md`, governed by Step 3.3's size rules.

When evidence is present, do not flag. **Pass 2, anti-pattern check:** only items that fail Pass 1 are matched against the named anti-patterns; matches become `YAGNI-###` findings whose body names the failing evidence type, the matched anti-pattern, and the simpler form considered. +YAGNI in `/code-review` is **advisory-only** and runs as a two-pass procedure. **Pass 1, evidence test:** for every +speculative addition (defensive code, single-implementation interfaces, configuration knobs no caller sets, +instrumentation for non-flowing telemetry), check whether the diff contains evidence of need from one of the acceptable +evidence types in [`yagni-rule.md`](../../../han-coding/references/yagni-rule.md).

A small index points to it.** The actual standard is a single readable document under your project's coding-standards directory (usually `docs/coding-standards/`). That is the only copy. The files under `.claude/rules/coding-standards/` are small index files, one per file type (for example, `typescript.md`, `ruby.md`, `svelte.md`), each carrying a `paths:` glob, a short load-on-demand instruction, and a list of bullet entries that link back to the canonical standards. The canonical standard itself is never copied; only its title, link, and a short description appear in the index. - -**Why not store the standards directly inside `.claude/rules/`?** Because `.claude/` is a directory most teams treat as tool configuration, not human-readable documentation. Standards are documents people open in pull request reviews, link from onboarding pages, and read on GitHub. They belong in `docs/`. The index files let Claude Code find them through its rules surface without dragging the source-of-truth out of the docs tree. - -**Why a per-file-type index instead of one rule file per standard?** The prior layout, one symlink under `.claude/rules/coding-standards/` per standard, each pointing to a full standards file with its own `paths:` frontmatter, meant every standard whose globs matched the current file was loaded into context the moment Claude opened that file. On a project with dozens of standards, a single `Read` on a `.ts` file could pull tens of thousands of tokens of standards material into context, all at once, with no chance for Claude to evaluate relevance first. After auto-compact, the same files would re-load on the next `Read` and the cycle would repeat. - -The per-file-type index files invert that. Each index file is small: a `paths:` block, a brief load-on-demand instruction, and a list of entries with 1-3 sentence descriptions. When Claude opens a file that matches the index, only the small index loads. Claude then reads the descriptions, decides which (if any) standards are relevant to the work at hand, and uses the `Read` tool to open only those. Standards that do not apply stay on disk. - -**Why not enumerate standards in `CLAUDE.md`?** Claude Code's path-scoped rules (see [Claude Code memory](https://code.claude.com/docs/en/memory)) load a rule only when a file matching its `paths:` glob is read. A `typescript.md` index will not load when you are editing a Ruby file, so file types unrelated to the current work do not bloat session startup.

They challenge evidence, challenge the fix, and challenge assumptions. Counter-evidence becomes `V#` findings that reshape the plan. -5. **Summary and user review.** The skill writes the Summary section at the top of the report. It then dispatches `readability-editor` to rewrite the write-up for the engineer who will implement the fix, preserving every fact and `file:line` reference.

The cost is the loop itself: a multi-turn, tight iteration where each behavior is three phases (red, green, refactor) and each phase runs your test command. The most expensive single factor is the number of test list items multiplied by your suite's runtime, since the full suite runs at green and after every refactor. This is a tight-loop skill built to run while you build, not an infrequent high-signal report. Keeping the test list scoped (the skill flags lists past ~10 items) is the main lever on total cost. +`/tdd` runs on the main agent.

Classic TDD says green should "commit whatever sins are necessary" and clean up in refactor. Taken literally, that would mean ignoring coding standards while going green. The skill splits the difference. Standards that govern *correctness and architectural placement* (which boundary code must go through, where it is allowed to live, which contract it honors) are obeyed in green. Violating an ADR boundary is not a temporary sin you tidy later; it is the wrong code. Stylistic and structural standards, the kind you genuinely can defer, are the refactor hat.

The skill does not recommend tests that reach into private methods, internal state, or implementation structure: if two implementations would produce the same observable behavior, the test must pass for both.

Technical fidelity is quarantined to Section 3 and is only added when you explicitly opt in. -- **Purpose-conditioned "Where to start."** If you say *why* you are running the comparison (for example, "before a redesign pass"), the report opens Section 1 with a short, explicitly-labeled "Where to start" view: up to five gaps that most block that purpose, one reason each. This is the skill's own prioritization judgment layered on top of the analyzer's neutral, unprioritized gap list, never replacing it, and omitted entirely when no purpose is given. The `gap-analyzer` itself stays neutral and does no prioritization. -- **Whole-report caveats surface once.** A provenance concern that applies to the whole comparison surfaces once, as an "Analysis caveats" note in Section 4. The most common case: the desired-state artifact is a provided, uncommitted, same-session source. This caveat is not repeated as a finding on every gap, and it is not folded into any gap's confidence. The evidence rule's scrutiny for `provided` sources is preserved; only the per-gap noise is removed. -- **Stable `G-NNN` gap IDs.** Every gap gets a citable ID assigned in discovery order. Tickets, threads, and follow-up reports reference the IDs. Sections 3 and 4 cross-reference them without restating the plain-language explanation. -- **The swarm runs by default.** A minimum viable team ships at every size and you opt out with `no swarm` if you want the lightweight pass. The swarm's job is to corroborate, contradict, and enrich what `gap-analyzer` produced, and to surface gaps the analyzer missed because it only thought about one actor type. -- **Actor-perspective sweep is built in.** `junior-developer` is a required swarm member. It runs an explicit actor sweep across every gap: enumerate every actor the desired state addresses or implies (human users and sub-roles, API callers, AI agents, integration partners, batch processes, internal services), check whether the gap holds for each actor, and raise `proposed_new_gap` whenever the analyzer's gap is correct for one actor but a *different* gap exists for another. The sweep no longer depends on you naming the actors in your prompt. `gap-analyzer` reports the actors and modes it observed in the desired state, and the skill seeds the sweep with that list as a floor that `junior-developer` then expands. -- **Four sections, progressively disclosed.** Executive Summary → Indexed Gaps → optional Technical Details → Swarm Findings (default-on). Reading stops anywhere; what came before stands on its own. Optional sections are physically omitted when not requested, not collapsed. -- **IA-designed template.** The report template was designed by `information-architect` against Rosenfeld & Morville's four IA systems, DITA topic typing, LATCH, Mark Baker's "Every Page is Page One", John Carroll's minimalism, JoAnn Hackos's audience-task mapping, and Dan Brown's 8 Principles of IA.

The stakeholder-readable artifact. Four sections, progressively disclosed: - - **Section 1: Executive Summary.** Plain-language verdict on overall alignment, a magnitude-at-a-glance table broken down by category (Missing / Partial / Divergent / Implicit), 3-5 bullets describing the *shape* of the gap thematically, a *"what this means for the work ahead"* paragraph, and a pointer to subsequent sections. When you stated a purpose for the comparison, the section also opens with a labeled "Where to start" view: up to five gaps that most block that purpose, one reason each. - - **Section 2: Indexed Gaps.** A scan-view index table mapping gap IDs to plain-language titles and categories, followed by one self-contained entry per gap. Each entry has plain-language `Expected` and `Current` descriptions, a `Why it matters` paragraph, and a `Confidence` field (High / Medium / Low) with a one-sentence reason. - - **Section 3: Technical Details** *(included only when requested).* Per-gap technical fidelity: `Locations` (file paths, anchors), `Relevant identifiers` (function, class, module names), `Specifics of the divergence`, `Remediation direction`, `Effort signal` (Trivial / Small / Medium / Large / Unknown), `Risks / dependencies`. Cross-references to Section 2 by `G-NNN` ID. - - **Section 4: Swarm Findings** *(included only when a swarm ran).* Confirmations, Contradictions, and Augmentations from the swarm, grouped by signal type and cross-referenced by `G-NNN` ID.

Adding +Section 3 augments the report. It never changes the meaning of Sections 1 and 2. ## How to get the most out of it -- **Be explicit about which is current and which is desired.** The default direction is current → desired (what's missing from the implementation relative to the spec). Reversing the direction yields a different finding shape: scope creep, undocumented capabilities, drift in the desired-state artifact. Name the direction up front when it matters. -- **Let the default swarm run unless you have a reason not to.** The default modes (swarm runs at the recommended size, plain language only) produce a stakeholder-readable report with `High` / `Medium` / `Low` confidence on each gap and explicit actor-perspective coverage from `junior-developer`. Drop to the lightweight pass (`no swarm`) when you're doing rapid first-pass scoping and don't need confidence signals yet. -- **Use `lightweight` when you want some validation but not full coverage.** The `lightweight` mode keeps the two required roles (`adversarial-validator` and `junior-developer`) and drops everything else. You get adversarial counter-evidence and an actor sweep without paying for domain specialists when the gaps don't warrant them. -- **Match swarm size to the analysis, not the calendar.** The skill recommends small (2–3 agents, no PM), medium (4–6 agents with PM), or large (6–8 agents with PM) based on gap count, distribution across categories, and the domains the gaps touch. Override the recommendation only when you have a specific reason (for example, the analysis touches auth even though only two gaps were found: promote to medium and include `adversarial-security-analyst`). -- **Name specialists you know you want.** If gaps cluster in a single domain (auth, data, UX, deployment, resilience, architecture), naming the matching specialist (`adversarial-security-analyst`, `data-engineer`, `user-experience-designer`, `devops-engineer`, `on-call-engineer`, `software-architect`, `system-architect`) ensures they are included regardless of what the heuristic would have picked. The three required swarm roles (`adversarial-validator`, `junior-developer`, plus `evidence-based-investigator` when the current state is concrete) are always there. -- **Expect a second round when the swarm finds the analyzer missed an actor type.** When the first-round swarm surfaces ≥ 3 `proposed_new_gap` entries or contradictions on ≥ 20% of gaps, the skill runs one additional pass with `gap-analyzer` to re-scan with the new actor context. That round is scoped to find *additional* gaps in the under-covered actor or behavior class, plus recategorizations and withdrawals; it does not re-confirm gaps the swarm already corroborated. It is bounded to one extra round, never iterative beyond that. -- **State your purpose to get a "Where to start" shortcut.** On a long report, the fastest way to cut through it is to tell the skill why you are comparing (*"before a redesign pass," "to scope the next sprint"*). The report then opens with a short, labeled list of the gaps that most block that goal. Without a purpose, you get the full unprioritized list and no shortcut. That is the right default when there is no single goal to prioritize against. -- **Pair with `/plan-implementation` downstream.** Once a gap analysis identifies the gaps, `/plan-implementation` produces a committable plan to close them. The pairing is natural: the gap report's Section 2 IDs become work items in the implementation plan; Section 3 (when present) feeds the technical detail straight into the plan's Implementation Approach section. -- **Pair with `/plan-a-phased-build` when remediation spans phases.** When the gap report shows gaps that cannot all be closed in one deliverable slice, run `/plan-a-phased-build` with the gap report as the source. The `G-NNN` IDs become source citations on the phase entries that close them, and the phased plan flows into `/plan-implementation` per phase. -- **Pair with `/iterative-plan-review` upstream.** When the desired-state artifact is itself a plan you don't yet trust, run `/iterative-plan-review` on it first. A gap analysis against a flawed desired-state produces flawed gaps. Hardening the desired-state before comparing pays for itself. -- **Re-run after the spec or implementation changes.** A gap analysis is a point-in-time artifact. It does not auto-refresh. After the implementation closes gaps (or after the spec changes), re-run the skill. The new report's `G-NNN` IDs are independent of the prior run's. The prior report stays valid as a snapshot. -- **Use bidirectional mode when the desired-state artifact is itself drifting.** Bidirectional analysis catches the *current state has capabilities the desired state never specified* failure mode: scope creep, undocumented behavior, capabilities that were shipped without an explicit spec. The default unidirectional pass misses this entirely. -- **Read Section 1 even if you wrote it.** The IA-designed template is structured so a stakeholder reading only Section 1 has a complete (low-resolution) understanding of the gap. Use it as a sanity check on your own framing. If Section 1 doesn't read well to a non-technical audience, the executive-summary translation step in the skill needs adjusting and you should re-run with a sharper prompt. +- **Be explicit about which is current and which is desired.** The default direction is current → desired (what's + missing from the implementation relative to the spec).

It is bounded to one extra round, never iterative beyond that. +- **State your purpose to get a "Where to start" shortcut.** On a long report, the fastest way to cut through it is to + tell the skill why you are comparing (_"before a redesign pass," "to scope the next sprint"_). The report then opens + with a short, labeled list of the gaps that most block that goal. Without a purpose, you get the full unprioritized + list and no shortcut. That is the right default when there is no single goal to prioritize against. +- **Pair with `/plan-implementation` downstream.** Once a gap analysis identifies the gaps, `/plan-implementation` + produces a committable plan to close them. The pairing is natural: the gap report's Section 2 IDs become work items in + the implementation plan; Section 3 (when present) feeds the technical detail straight into the plan's Implementation + Approach section. +- **Pair with `/plan-a-phased-build` when remediation spans phases.** When the gap report shows gaps that cannot all be + closed in one deliverable slice, run `/plan-a-phased-build` with the gap report as the source. The `G-NNN` IDs become + source citations on the phase entries that close them, and the phased plan flows into `/plan-implementation` per + phase. +- **Pair with `/iterative-plan-review` upstream.** When the desired-state artifact is itself a plan you don't yet trust, + run `/iterative-plan-review` on it first. A gap analysis against a flawed desired-state produces flawed gaps. + Hardening the desired-state before comparing pays for itself. +- **Re-run after the spec or implementation changes.** A gap analysis is a point-in-time artifact. It does not + auto-refresh. After the implementation closes gaps (or after the spec changes), re-run the skill. The new report's + `G-NNN` IDs are independent of the prior run's. The prior report stays valid as a snapshot. +- **Use bidirectional mode when the desired-state artifact is itself drifting.** Bidirectional analysis catches the + _current state has capabilities the desired state never specified_ failure mode: scope creep, undocumented behavior, + capabilities that were shipped without an explicit spec. The default unidirectional pass misses this entirely. +- **Read Section 1 even if you wrote it.** The IA-designed template is structured so a stakeholder reading only Section + 1 has a complete (low-resolution) understanding of the gap. Use it as a sanity check on your own framing. If Section 1 + doesn't read well to a non-technical audience, the executive-summary translation step in the skill needs adjusting and + you should re-run with a sharper prompt. ## Sizing -Size determines the swarm composition.

The judgment-heavy work (identifying comparison areas, mapping correspondences, classifying gaps into the Missing / Partial / Divergent / Implicit taxonomy, gathering evidence pairs from both inputs) happens inside the `gap-analyzer` agent. The skill orchestrates that agent, runs a validator-and-augmenter swarm by default, then translates the analyzer's structured output into the IA-designed template. +The skill's input is two artifacts and its output is a stakeholder-readable report.

The skill orchestrates that agent, +runs a validator-and-augmenter swarm by default, then translates the analyzer's structured output into the IA-designed +template. **Default-on swarm posture.** The swarm runs by default for three reasons. -First, `gap-analyzer` is generalist by design: it identifies feature-and-behavior correspondences across two artifacts. It reports the actor types and modes it observed in the desired state, and the skill seeds `junior-developer` with that list, but the analyzer does not itself reason about whether each gap holds per actor. `junior-developer`'s actor sweep catches the failure mode where a gap is correct for human users but a *different* gap exists for API callers or AI agents that the analyzer never considered, expanding past the observed-actor floor. - -Second, the swarm produces per-gap confidence signals (High / Medium / Low) that change how stakeholders prioritize. Stakeholder-readable reports benefit from confidence even when the gap list is small. - -Third, contradictions surfaced by `adversarial-validator` are decision-bearing: they need adjudication before remediation. Waiting for a stakeholder to opt in to discover them would be the wrong default. - -The lightweight (`no swarm`) path remains available for rapid first-pass scoping where confidence is not yet a decision input. - -**Required swarm roles.** At every size, the swarm includes `adversarial-validator` (attacks gap-analyzer's findings with counter-evidence) and `junior-developer` (runs the actor-perspective sweep across human users, API callers, AI agents, integration partners, batch processes, and internal services). `evidence-based-investigator` is required when the current state is concrete enough to verify against, effectively always at medium and large. `project-manager` is required at medium and large to consolidate Section 4 content from the four-or-more specialist outputs; at small (two or three agents) the skill consolidates deterministically without PM. - -**Sizing rule.** Small analyses (0-3 gaps, single domain, no security / data / cross-service signals) ship the minimum viable swarm (2–3 agents, no PM). Medium analyses (4-10 gaps, two or three adjacent domains, may touch one cross-cutting concern) ship a 4–6 agent swarm with PM. Large analyses (11+ gaps, multi-domain cross-cutting concerns, security or data implications, or explicit user request) ship a 6–8 agent swarm with PM. Augmenters are drawn from the standard han specialist roster based on what the gaps touch. - -**Conditional second round.** Single-round parallel fan-out captures most of the value. The one failure mode it can miss is the analyzer systematically excluding an actor type. For example, comparing a spec written for human users against an implementation that also serves API callers, where every gap-shaped finding has a parallel API-caller-shaped finding the analyzer never considered. When the first-round swarm surfaces ≥ 3 `proposed_new_gap` entries (Trigger A) or contradictions on ≥ 20% of gaps (Trigger B), the skill re-dispatches `gap-analyzer` once with the new actor context and merges the delta into the source file. A fired trigger is a proxy for an under-covered actor or behavior class; the proposed gaps are a symptom of it. So the round re-scans that class for *additional* gaps and surfaces recategorizations and withdrawals, and is explicitly told not to spend the pass re-confirming gaps the swarm already corroborated. Bounded to one extra round. - -**Plain-language translation.** The `gap-analyzer` agent produces structured output rich in technical detail: file paths, line numbers, document anchors, code identifiers. The skill's render step translates each gap's `Expected`, `Current`, and `Why it matters` content into plain language for Sections 1 and 2. It strips every code or document-mechanic reference and replaces it with a capability-or-behavior description. Technical fidelity is preserved in `gap-analysis-source.md` and, when you opt in, surfaces in Section 3 with full evidence pairs intact. - -**Append-only `G-NNN` IDs.** Gap IDs are assigned in the order the analyzer surfaced the gaps, including any `proposed_new_gap` entries the swarm added. IDs are stable for the life of the report and not renumbered if a re-run produces a different gap set. Re-running creates a new report, with its own ID space, rather than editing the prior report in place. - -**Optional sections are physically omitted.** When Section 3 or Section 4 is not requested or generated, the skill removes the section from the rendered output entirely (and removes the corresponding `sections_included` entry from the front matter). The "How to Read This Report" frame at the top of the template is rewritten to reflect what was included so a reader is never promised a section that does not exist. +First, `gap-analyzer` is generalist by design: it identifies feature-and-behavior correspondences across two artifacts. +It reports the actor types and modes it observed in the desired state, and the skill seeds `junior-developer` with that +list, but the analyzer does not itself reason about whether each gap holds per actor. `junior-developer`'s actor sweep +catches the failure mode where a gap is correct for human users but a _different_ gap exists for API callers or AI +agents that the analyzer never considered, expanding past the observed-actor floor. + +Second, the swarm produces per-gap confidence signals (High / Medium / Low) that change how stakeholders prioritize. +Stakeholder-readable reports benefit from confidence even when the gap list is small. + +Third, contradictions surfaced by `adversarial-validator` are decision-bearing: they need adjudication before +remediation.

Then +rerun the skill in validate mode the next time someone executes the procedure, to refresh `Last validated`. ## In more detail The skill walks an eight-step process: 1. **Determine mode.** Creating new, Updating existing, or Validating existing. -2. **YAGNI preflight.** Gate the work on real evidence: alert that has fired, incident, recurring task, live failure mode, customer commitment. Recommend deferral when no trigger exists; the user can override and the override is recorded. -3. **Discover project structure.** Resolve the runbooks directory from CLAUDE.md's Project Discovery section, then `project-discovery.md`, then defaults (`docs/runbooks/`, `runbooks/`). Detect whether the project organizes runbooks flat, per-service, or alert-keyed. -4. **Gather context.** Title, severity, triggers, reversibility, origin, owner, prerequisites, symptoms, the procedure with exact commands and expected output, verification, escalation conditions and channels, rollback. -5. **Write the runbook.** Copy the template, fill the metadata, fill each required section, fill applicable optional sections, delete the headings for optional sections that do not apply, delete the author guidance block. -6. **Integration.** CLAUDE.md or AGENTS.md entry if the project lists runbooks; back-reference from incident reports or post-mortems; comment in alert-definition files that point to the runbook. -7. **Verification.** Re-read the file and confirm no placeholders remain. Confirm Origin contains real evidence (or an explicit override), Symptoms is concrete, and every step shows command and expected output. Confirm Verify is distinct from per-step output, Escalate leads with conditions, and Rollback is filled or explicitly marked not applicable. Confirm empty optional sections are deleted and the change-history creation entry exists. -8. **Readability self-check.** Run the standardized readability self-check over the runbook's prose regions, confirm each criterion, and fix any failure before presenting. The skill runs no rewrite pass, so this self-check is the output's fidelity guard. - -The template is reviewed by [`information-architect`](../../agents/han-core/information-architect.md) and [`junior-developer`](../../agents/han-core/junior-developer.md) inputs that landed during its design pass.

The agent authors the description with a fresh-reviewer perspective, anticipating what a teammate without full project context needs to see. Once the draft exists, a `readability-editor` agent rewrites it against the shared readability standard for the reviewer who will read the code, preserving every fact and reference identifier.

The skill builds the map from the cross-repo work-order prose at the top of the file, corroborated by the file paths inside each item. It shows you the map for confirmation before it writes or creates anything. -- **Within-repo blockers only.** A native `blocked_by` link is always within a single repo. Cross-repo coordination (deploy ordering, merge gates) lives in prose at the top of the file, never as a native blocker link. A cross-repo `Depends on` is a format error the skill surfaces for repair. -- **Per-repo work-items file.** For each target repo, the skill writes a `<repo-name>.work-items.md` next to the source. It is a filtered view of the source carrying only that repo's items, and it is the file the publish scripts read. The source file is never modified by publishing. -- **Reference artifacts, not process artifacts.** Every issue body links the artifacts an implementer needs: API and event contracts, design frames, schema docs, ADRs, coding standards. It never links the process artifacts that record how the plan was reached: iteration histories, decision logs, review findings. The full include and exclude lists live in [the reference artifact inventory](../../../han-github/skills/work-items-to-issues/references/reference-artifact-inventory.md). -- **Screenshots copied into the target repo.** When the plan folder has a `ui-designs/` subfolder, UI items embed their screenshots inline. The skill copies each PNG into the target repo first, then embeds a same-repo raw URL. It does this because the automated implementation tooling cannot resolve a URL that points into a different repository. See [the screenshot embed rules](../../../han-github/skills/work-items-to-issues/references/screenshot-embed-rules.md). -- **Evidence-based repair.** When a format check fails, the skill proposes a fix backed by a concrete source: a file path with line number, a plan section, or an ADR ID. You can continue with the fills, correct them, or stop. Fills without evidence are surfaced as gaps, not applied silently. -- **Idempotent publish.** The publish pipeline resumes cleanly after a partial failure. Items already annotated with their issue number are skipped, and screenshot uploads overwrite in place. -- **No label, no assignee by default.** Issues are created unlabeled and unassigned.

The work-items file is an already-committed decomposition, and this skill publishes it without adding new behavioral commitments or speculative infrastructure. The closest thing to a gate here is the reference-artifact rule: issue bodies carry the contracts, designs, and standards an implementer needs. They leave out the process artifacts that only record how the plan was reached. That is content hygiene, not YAGNI. +YAGNI does not gate this skill's output.

All of its work runs in-process: reading the file, building and confirming the item-to-repo map, validating the format with evidence-based repair, writing the per-repo files, and running the publish pipeline. The cost is the GitHub API traffic the publish scripts generate (one issue creation per item, one screenshot upload per embed, one dependency link per blocker). The most time-consuming step is publishing a large multi-repo file. The skill is built for a once-per-breakdown cadence, and its idempotent pipeline means a re-run after an interruption only does the work that remains. +The skill dispatches no agents.

Note any target repo, label, or assignee you named. -2. **Build the item-to-repo map.** Read the cross-repo work-order prose for the primary mapping, then corroborate it against the file paths inside each item. When the two disagree for an item, the skill surfaces the conflict before proceeding. -3. **Validate the format with evidence-based repair.** Check the file against the format invariants the publish scripts depend on (heading shape, `Depends on` syntax, within-repo blockers, screenshot URL scheme, references present, no process artifacts). When a check fails, propose a fix backed by a concrete source and give you three actions: continue with the fills, correct them, or stop. -4. **Show the item-to-repo map for confirmation.** Present the table and wait. Nothing is written or created until you confirm. -5. **Write the per-repo work-items files.** For each target repo, write a filtered `<repo-name>.work-items.md` next to the source. This is the file the publish scripts read. -6. **Publish each per-repo file.** Run the publish pipeline, which runs three idempotent scripts in order.

Unlike the GitHub sibling, this skill does not split work across repos. If the source file spans several code repos, the repo prose is informational only. It never changes which team an issue lands in. -- **The Linear MCP server is required.** The skill checks the server is connected before it does any work. If the server is missing or not authenticated, the skill stops. It drives Linear entirely through the MCP server. There is no CLI and no shell-script pipeline. -- **Discovery over assumed defaults.** Linear teams each define their own workflow states, labels, and Projects, so the skill reads the target team's real configuration and resolves every option against it before creating anything. It does not assume a label or a state exists. When you have not said how to categorize the work, it presents the team's real labels and lets you pick one, several, or none. -- **No issue types.** Linear has no issue-type concept, so the skill never asks for or sets one. Categorization is done with the team's real labels, chosen by you. -- **Grouping the Linear way.** You can group the created issues under a Linear **Project** and nest them as **sub-issues** under a **parent issue**. Both are optional and independent. A Project is resolved at workspace scope and confirmed against the team; a parent issue is resolved within the team. -- **Native dependency relations.** Every SYM named in a `Depends on` line must resolve to another slice in the same file. After all issues exist, the skill creates a native Linear "blocked by" relation from each dependent issue to its blockers. Relations are append-only and de-duplicated, so a re-run never doubles them. -- **Reference artifacts, not process artifacts.** Every issue description carries the artifacts an implementer needs: API and event contracts, design references, schema docs, ADRs, coding standards. It never carries the process artifacts that record how the plan was reached: iteration histories, decision logs, review findings. The full include and exclude lists live in [the reference artifact inventory](../../../han-linear/skills/work-items-to-linear/references/reference-artifact-inventory.md). -- **No image embedding.** Design references are carried as links in the issue. Add image attachments in Linear by hand if an issue needs them. -- **Evidence-based repair.** When a format check fails, the skill proposes a fix backed by a concrete source: a file path with line number, a plan section, or an ADR ID. You can continue with the fills, correct them, or stop. -- **Idempotent resume.** After an issue is created, its slice heading in the source file is annotated with the Linear identifier.

The work-items file is an already-committed decomposition, and this skill publishes it without adding new behavioral commitments or speculative infrastructure. The closest thing to a gate here is the reference-artifact rule: issue descriptions carry the contracts, designs, and standards an implementer needs. They leave out the process artifacts that only record how the plan was reached. That is content hygiene, not YAGNI. +YAGNI does not gate this skill's output.

Its work runs in the conversation context. A few Linear MCP reads preflight the server and resolve the target against the live team. Then format validation runs with evidence-based repair, one create call fires per item, a relation call fires per dependency, and a small batch of reads checks existing identifiers on a resume. The most time-consuming runs are large work-items files, because issue creation is one call per item. The skill is built for a once-per-breakdown cadence, and the heading annotations mean a re-run after an interruption only creates the issues that remain. +The skill dispatches no agents.

Give it: -1. **The plan file, strongly preferred.** A concrete path to the plan (for example, `docs/features/bulk-export/feature-implementation-plan.md` or `~/.claude/plans/my-plan.md`) is the preferred input. Without a path, the skill searches `~/.claude/plans/` for the most recently modified plan. -2. **Review mode override, optional.** The skill evaluates complexity and chooses lightweight or team mode automatically, and states the choice with justification before proceeding.

If you want to correct the composition or the mode, say so and the skill adjusts. ## What you get back -The plan file edited in place, two companion files in `artifacts/` next to it (a third in spec-aware mode), and an in-channel summary: - -- The **plan file on disk, edited in place.** The skill does not produce a separate review document or a side-by-side diff file. It rewrites the plan so the committed version reflects every accepted change. Inline `(F#)` markers are not added to plan sentences; forward traceability lives in each finding's `Changed in plan:` field in `artifacts/review-findings.md`. (In spec-aware mode, load-bearing mechanic-driven spec sentences carry an inline `([T#](artifacts/feature-technical-notes.md#...))` link, but those are mechanic tags, not finding markers.) -- A **`## Review History` section appended to the plan**, pointing to the two companion files. This section is the only standardized structural change the skill makes to the plan itself. It records the review mode (lightweight or team), the iterations or rounds completed, and the team composition with a one-line justification per specialist (team mode only). It also records a one-line summary of assumptions challenged, consolidations made, and ambiguities resolved, plus the open items remaining and whether each blocks implementation. All pointing into the companion files for full detail. If a prior review already populated this section, the skill appends new counts rather than overwriting. -- An **`artifacts/review-findings.md`** companion file. One `F#` entry per refuted assumption, overlap finding, ambiguity, or unhandled edge case raised across the review. Each entry records the agent that raised it (`self-review` in lightweight mode, or the specialist name in team mode), the category, the finding text, and the evidence considered. It also records the resolution, what resolved it (`Resolved by:` evidence / user input / deferred), the `R#` round it was raised in (`Raised in round:`), and the plan sections that changed in response (`Changed in plan:`). This is where the review's full record lives. The plan file references entries by ID rather than inlining them. -- An **`artifacts/review-iteration-history.md`** companion file. One `R#` entry per iteration (lightweight) or round (team). Each entry records the mode, the specialists engaged, the `F#` findings raised that pass (`Findings raised:`), and the plan sections changed that pass (`Changed in plan:`). It also records the stability assessment made each iteration or round, and the next-step recommendation. This captures how the review progressed without bloating the plan. -- An **`artifacts/feature-technical-notes.md`** companion file, in spec-aware mode only and created lazily. When you refine a `feature-specification.md` and the review surfaces a load-bearing mechanic (one that affects observable behavior), the skill extracts it to a `T#` entry in this file rather than leaking the mechanic into the spec. It then links the spec sentence to that entry. The file is written only once at least one such `T#` exists; its absence means the review captured no load-bearing mechanics, not that the spec is incomplete. -- **Lightweight-mode details inside the findings.** Assumption verdicts (Verified / Refuted / Uncertain / Invalidated), the primary/secondary classification (when a primary is refuted, dependent secondaries collapse), overlap findings distinguishing internal overlap (redundant steps within the plan) from external overlap (steps that duplicate existing codebase patterns or utilities; consolidation proposed when overlap exceeds 80%), and ambiguity resolutions. -- **Team-mode details inside the findings.** Every specialist's output recorded as `F#` entries: assumptions refuted with counter-evidence, overlap with existing code or utilities, ambiguities needing resolution, and unhandled edge cases or failure modes. Round 2+ feeds prior findings back into agent prompts so the team does not re-raise resolved issues. -- **Contextual ambiguity questions** surfaced to you when a decision genuinely needs your judgment. Each with the impact, tradeoffs, and room for nuanced follow-up rather than binary choice. Answers flow back onto the matching `F#` entry's `Resolution:` / `Resolved by: user input` fields. -- **A final user review summary** in-channel. The plan file path, the two companion file paths, the review mode, the team composition (if applicable), the number of iterations or rounds, the findings resolved by evidence vs. user input vs. deferred, and any remaining open items. Followed by an explicit question asking whether you want further revisions on specific sections or consider the plan ready. - -The three files interlock through shared IDs. Every `F#` lists the `R#` round that raised it and the plan sections that changed. Every `R#` lists the `F#` findings it produced and the sections changed. Plan sentences carry no inline `(F#)` markers; each finding's `Changed in plan:` field is the forward link instead (spec-aware mode adds inline `([T#](...))` mechanic tags, which are not finding markers). The skill maintains these invariants as it writes, so cross-references stay consistent even across multiple review sessions on the same plan. - -For plan folders produced before the `artifacts/` layout was introduced, the companion files may sit at the plan folder's root instead of under `artifacts/`. The skill detects the legacy layout, continues appending to the existing files rather than migrating, and uses the legacy paths in the `## Review History` section and inline markers to keep cross-references stable. - -Every change written to the plan is traceable to a specific trigger: a `self-review` finding in lightweight mode, or a specialist agent finding and its evidence in team mode. The skill does not make silent edits. +The plan file edited in place, two companion files in `artifacts/` next to it (a third in spec-aware mode), and an +in-channel summary: + +- The **plan file on disk, edited in place.** The skill does not produce a separate review document or a side-by-side + diff file.

The plan file references entries by ID rather than inlining them. +- An **`artifacts/review-iteration-history.md`** companion file. One `R#` entry per iteration (lightweight) or round + (team). Each entry records the mode, the specialists engaged, the `F#` findings raised that pass (`Findings raised:`), + and the plan sections changed that pass (`Changed in plan:`). It also records the stability assessment made each + iteration or round, and the next-step recommendation. This captures how the review progressed without bloating the + plan. +- An **`artifacts/feature-technical-notes.md`** companion file, in spec-aware mode only and created lazily. When you + refine a `feature-specification.md` and the review surfaces a load-bearing mechanic (one that affects observable + behavior), the skill extracts it to a `T#` entry in this file rather than leaking the mechanic into the spec. It then + links the spec sentence to that entry. The file is written only once at least one such `T#` exists; its absence means + the review captured no load-bearing mechanics, not that the spec is incomplete. +- **Lightweight-mode details inside the findings.** Assumption verdicts (Verified / Refuted / Uncertain / Invalidated), + the primary/secondary classification (when a primary is refuted, dependent secondaries collapse), overlap findings + distinguishing internal overlap (redundant steps within the plan) from external overlap (steps that duplicate existing + codebase patterns or utilities; consolidation proposed when overlap exceeds 80%), and ambiguity resolutions. +- **Team-mode details inside the findings.** Every specialist's output recorded as `F#` entries: assumptions refuted + with counter-evidence, overlap with existing code or utilities, ambiguities needing resolution, and unhandled edge + cases or failure modes. Round 2+ feeds prior findings back into agent prompts so the team does not re-raise resolved + issues. +- **Contextual ambiguity questions** surfaced to you when a decision genuinely needs your judgment. Each with the + impact, tradeoffs, and room for nuanced follow-up rather than binary choice. Answers flow back onto the matching `F#` + entry's `Resolution:` / `Resolved by: user input` fields. +- **A final user review summary** in-channel. The plan file path, the two companion file paths, the review mode, the + team composition (if applicable), the number of iterations or rounds, the findings resolved by evidence vs. user input + vs. deferred, and any remaining open items. Followed by an explicit question asking whether you want further revisions + on specific sections or consider the plan ready. + +The three files interlock through shared IDs. Every `F#` lists the `R#` round that raised it and the plan sections that +changed. Every `R#` lists the `F#` findings it produced and the sections changed. Plan sentences carry no inline `(F#)` +markers; each finding's `Changed in plan:` field is the forward link instead (spec-aware mode adds inline `([T#](...))` +mechanic tags, which are not finding markers). The skill maintains these invariants as it writes, so cross-references +stay consistent even across multiple review sessions on the same plan. + +For plan folders produced before the `artifacts/` layout was introduced, the companion files may sit at the plan +folder's root instead of under `artifacts/`. The skill detects the legacy layout, continues appending to the existing +files rather than migrating, and uses the legacy paths in the `## Review History` section and inline markers to keep +cross-references stable. + +Every change written to the plan is traceable to a specific trigger: a `self-review` finding in lightweight mode, or a +specialist agent finding and its evidence in team mode. The skill does not make silent edits. ## How to get the most out of it -- **Pair with `/plan-implementation` upstream.** `/plan-implementation` produces the committable implementation plan; this skill stress-tests it. Running the two in sequence is the intended flow when you want a thoroughly hardened plan before implementation. The iteration count on this skill is usually small (1–2 rounds) when the upstream plan is already high-quality. -- **Point it at a path.** A concrete path is faster than letting the skill search `~/.claude/plans/`. It also eliminates ambiguity about which plan is being iterated when multiple are on disk. -- **Trust the mode selection.** The skill evaluates complexity and chooses lightweight or team mode with a justification. Override only when the apparent complexity understates the real risk (for example, a three-file plan that happens to touch auth or data migration). Running team mode on a simple plan burns tokens; running lightweight mode on a complex plan misses the cross-cutting review the team provides. -- **Name the specialists you know you want.** If the plan touches security, data, or operations, naming `adversarial-security-analyst`, `data-engineer`, or `devops-engineer` explicitly ensures they are included regardless of what the skill's heuristic selection would have picked. `junior-developer` and `adversarial-validator` are always there, and `evidence-based-investigator` joins whenever the plan contains codebase claims to verify. -- **Fewer additional specialists is usually better.** The team always has `junior-developer` and `adversarial-validator`, plus `evidence-based-investigator` when the plan has codebase claims to verify. Adding three more on top of those is usually enough. Going to five additional specialists is appropriate for cross-cutting plans but produces more findings to reconcile per round. -- **Let the iteration stop early.** The skill's stability assessment is designed to stop iterating when additional passes would only produce cosmetic changes. Trust the stop. If the plan isn't converging within the size-based cap (1 iteration for small, 2 for medium, 3 for large), the real problem is scope or decomposition, not iteration count. -- **Answer surfaced ambiguities succinctly.** The skill surfaces ambiguity as contextual questions with impact, tradeoffs, and room for nuanced follow-up. Accept or amend the implied recommendation. Do not re-litigate from scratch. The skill will not re-surface resolved questions in later rounds (team mode feeds prior-round findings back in so agents don't re-raise them). -- **Re-run after major plan rewrites.** If the plan is substantially rewritten between iterations (for example, the scope changes, a new section is added, a fundamental decision reverses), re-run the skill. The companion `artifacts/review-findings.md` and `artifacts/review-iteration-history.md` files capture the prior review sessions. The new run reads them, continues `F#` / `R#` numbering from the highest existing ID, and avoids re-raising resolved issues. -- **Use *"verify this will work"* framing when that's the intent.** The skill explicitly handles verification and feasibility-check requests (*"is this sound," "can you validate this," "check for correctness"*). Phrasing the request that way (rather than *"review this plan"*) ensures the skill treats the goal as critical evaluation rather than drafting, and surfaces open items as first-class output. +- **Pair with `/plan-implementation` upstream.** `/plan-implementation` produces the committable implementation plan; + this skill stress-tests it.

No sub-agents are dispatched. Cost is roughly equivalent to a focused in-model loop plus codebase reads per iteration.

The skill detects that layout and continues appending to the existing files rather than migrating. ## YAGNI -YAGNI is a first-class review pillar alongside correctness, completeness, risk, and feasibility. Every committed item in the plan under review (every step, abstraction, infrastructure addition, observability hook, configuration knob, test, ADR, or coding standard) must cite acceptable evidence that it is needed *now*. Items without evidence raise a `Category: YAGNI candidate` finding. Resolution paths are: cite the missing evidence (finding closes), replace with a strictly simpler version (the larger version moves to deferred), or move to `## Deferred (YAGNI)` with a named *reopen-when* trigger. Anti-patterns from the named list (single-implementation interfaces, runbooks for alerts that have never fired, indexes for queries that don't run, and so on) force a finding regardless of severity rules. - -See [YAGNI](../../yagni.md) for the two gates, the acceptable-evidence list, the named anti-patterns, and the deferral format. - -Evidence quality is a first-class review pillar alongside YAGNI. The companion [evidence rule](../../evidence.md) characterizes how strong the evidence is once YAGNI has gated inclusion. It names the trust class of each citation a plan item rests on (codebase, web, provided). It applies the corroboration gate to web-source claims that drive a recommendation (single-source web claims get marked and cannot stand alone). And it labels claims with no evidence at any tier as a distinct state rather than treating them as weak evidence.

It draws on the broader iterative-and-incremental tradition documented by Craig Larman and Victor Basili and embedded in every modern Agile framework. Iteration gives review input the chance to influence later review input (a finding from `adversarial-validator` in round 1 may sharpen what `evidence-based-investigator` looks for in round 2). The cap prevents runaway cycles when review has plateaued. The stability-assessment gate stops iteration early when further passes would only produce cosmetic change. +The skill's loop is rounds of review plus facilitated edits until convergence, capped by plan size at one to three +passes.

The skill's iteration checklist classifies assumptions as primary (stand on their own) or secondary (depend on primaries), and requires primaries to be evaluated first. When a primary is refuted, dependent secondaries collapse without independent evaluation. This is the Five Whys applied to plan assumptions: a refutation at the root propagates through the tree. Cosmetic debate about a dependent assumption does not paper over the real problem at the parent. +Root-cause analysis via repeated "why" questioning, popularized at Toyota and adopted widely in software and design +practice, underpins the skill's assumption-evaluation step.

The practice traces to military red-teaming, Roman Catholic *Advocatus Diaboli* practice, and modern decision-analysis literature (for example, Klein's pre-mortem). The skill enforces this through team mode's required roster: `adversarial-validator` assumes the plan will fail and searches for counter-evidence, and `junior-developer` reframes the plan in plain language to surface assumptions a specialist might miss. The required specialists `junior-developer` and `adversarial-validator` (joined by `evidence-based-investigator` when the plan has codebase claims to verify) are the red team.

The skill's overlap check and assumption evaluation reflect this discipline. Assumption verdicts must cite code, docs, or existing patterns. Overlap findings must reference specific utilities or prior work in the codebase. And vague claims (*"this assumes the API returns JSON"*) are not actionable until grounded in a concrete file and line (*"the API handler at `src/api/handler.go:47` returns XML, not JSON"*). +Adzic's _Specification by Example_ formalizes the practice of grounding specifications and plans in concrete, testable +examples and evidence drawn from real scenarios rather than abstract claims.

When the specialist findings get technical and the trade-offs get entangled, `junior-developer` reframes the question in plain terms a generalist would ask. That frequently exposes an unstated assumption or a simpler question the team can answer without escalating to you. The rubber duck applied to plan review is the resolution step that turns "escalate to user" into "resolve inside the team." +Andy Hunt and Dave Thomas's "rubber duck" practice (explaining a problem out loud in plain language to surface the gaps +in your own reasoning) informs the skill's `junior-developer` role in team mode.

The skill's stability assessment encodes this discipline: iteration continues only if the next pass has at least an 80% chance of producing a *meaningful structural* improvement. Cosmetic changes (rewording, reformatting) explicitly do not count. The skill stops when the plan meets its implicit definition of done: evidence-grounded assumptions, documented overlap, resolved ambiguities, and no further structural improvement available. +Acceptance criteria and Definition of Done are the standard project-management artifacts for making "done" testable +rather than subjective.

A future reader can reopen it cleanly if evidence changes. The skill's iteration summary section encodes these directly into the plan: assumptions challenged with evidence, consolidations made, ambiguities resolved and how, and open items remaining with block/non-block classification. Every edit records the trigger (checklist section in lightweight, agent finding in team mode), so the plan carries its own review history forward. +The RAID log (Risks, Assumptions, Issues, Decisions) and the Agile-era decision log are the standard project-management +artifacts for recording the _what_ and the _why_ of a decision.

When a read-only tool that authoritatively answers a question is already available to the session (for example, a connected schema or data-source tool), it queries that too. Your judgment is reserved for decisions that genuinely need it. -- **Behavioral specification.** The spec describes outcomes, flows, states, and coordinations. Not libraries, file paths, or data shapes. Technical detail is admissible only as evidence for a behavioral decision. -- **Decision tree walking.** Foundational decisions (what, who, outcome, trigger) settle before behavioral ones (flows, states); behavioral before boundary (edge cases); boundary before interaction (UI/API surface). -- **Specialist review round.** Three to five sub-agents stress-test the draft in parallel. `junior-developer` is always in the mix. `project-manager` reconciles their findings. -- **Cross-referenced artifacts.** Every non-obvious behavior in the spec carries an inline `([D#](...))` marker linking to the decision that drove it. Every `F#` finding links to the `D#` it touched and the spec section it changed. +- **Explore before asking.** The skill reads the codebase, ADRs, and coding standards before surfacing a question.

The primary behavioral spec, structured as: Outcome, Actors and Triggers, Primary Flow, Alternate Flows and States, Edge Cases and Failure Modes, User Interactions, Coordinations, Out of Scope, a `Deferred (YAGNI)` section (written only when at least one item was deferred), Open Items, and a Summary with counts. Non-obvious behaviors carry inline parenthetical markers (for example, `([D4](artifacts/decision-log.md#d4-invite-expiration-window))`) linking to the decision that drove them. Technical details (libraries, data shapes, specific file paths) do not appear here. They appear only as *Evidence* under the corresponding decision in the decision log, or as a `T#` technical note when the mechanic is load-bearing for the spec. -- An **`artifacts/decision-log.md`** file at `{folder}/artifacts/decision-log.md`. One `D#` entry per decision the interview settled, with the question, the behavioral decision, the rationale, and the evidence or user input that settled it. Each entry also records the rejected alternatives with reasons, the dependent decisions that rested on it (`Dependent decisions:`), the review findings that reshaped it (`Driven by findings:`), and the spec sections that cite it (`Referenced in spec:`). Future readers can trace *why* the spec says what it says, and reopen a decision cleanly if the evidence changes. -- An **`artifacts/team-findings.md`** file at `{folder}/artifacts/team-findings.md`. One `F#` entry per finding the review team raised. Each entry records which specialist raised it (`Agent:`), the finding text, the evidence considered, and the resolution with what resolved it (`Resolved by:` evidence / user input / project-manager). It also records the decisions it touched (`Affected decisions:`) and the spec sections it changed (`Changed in spec:`). -- An optional **`artifacts/feature-technical-notes.md`** file at `{folder}/artifacts/feature-technical-notes.md`. **Lazily created**, written only when at least one load-bearing mechanic surfaces during the interview or review that the spec needs in order to describe a behavior correctly. Each entry is a `T#` note linked from the spec via `([T#](artifacts/feature-technical-notes.md#t#-slug))` and back to the decisions it supports (`Supports decisions:`) and the findings that drove it (`Driven by findings:`). If no `T#` qualifies, the file is never created and the spec contains no `T#` links. -- An **open items list** inside the spec. Questions or concerns the project-manager flagged that could not be resolved during specification, each with what would resolve it and whether it blocks implementation. -- A **summary** returned in-channel.

Every +rejected alternative is recorded with the reason it was rejected. The spec is not "done" while a blocking open item +remains. The skill surfaces it rather than inventing an answer. ## How to get the most out of it -- **State the feature and the outcome up front.** The single biggest lever. One to two sentences on what the feature does and what successful use produces collapses whole classes of early-interview questions. -- **Let the skill explore before asking.** The skill is designed to read the codebase, ADRs, coding standards, and existing specs before surfacing a question. If you start answering questions before the skill has explored, the spec fills up with user judgment where codebase evidence could have settled the decision instead. -- **Point it at upstream product context.** A PRD, product brief, linked issue, meeting transcript, or previous spec sharpens every decision in the tree. The skill doesn't invent product intent. It needs something to ground it. -- **Let the decision tree descend.** The skill walks foundational decisions first (what, who, outcome, trigger, done), then behavioral (flows, states, coordinations), then boundary (edge cases, failure, out of scope), then interaction (UI / API surface). Jumping ahead (*"but what about error state X?"*) before the parent decision is settled usually produces an answer that has to be rewritten later. -- **Use the recommendations.** Every question surfaced to you comes with a recommended answer grounded in evidence. Accepting or redirecting a recommendation is much faster than answering from a blank page. -- **Treat the decision log as a durable artifact.** `artifacts/decision-log.md` exists so future readers (and future planning sessions) can trace why the spec says what it says. When a decision is later reopened (because evidence changed), the log tells you exactly what the original rationale was, which findings reshaped it, and which spec sections depend on it. Do not edit the spec's inline `([D#](...))` markers without updating the matching entry in the decision log. -- **Expect a review round.** Once the draft is written, three to five sub-agents review it in parallel. The skill does not present their raw findings to you. It first tries evidence-based resolution, and only escalates the findings that genuinely need user judgment, organized by the decision they affect. Trust that loop rather than asking for the raw agent output. -- **Pair with `/plan-implementation` next.** This skill produces *what*. The `/plan-implementation` skill turns that into *how*: decomposition, sequencing, RAID log, testing strategy, operational readiness, rollback. Running the two in sequence is the intended flow. For the full end-to-end planning workflow from rough idea to individual work items, see [How to plan a feature, end to end](../../how-to/plan-a-feature.md). -- **Re-run when the spec must change.** If the outcome materially shifts (new constraint, new stakeholder, new evidence from production), re-run the skill with the new context and let it walk the tree again. The existing spec, decision log, and team findings all become inputs to the new run. Prior `D#` / `F#` IDs carry forward so cross-references remain stable. +- **State the feature and the outcome up front.** The single biggest lever.

For the cross-skill sizing model and design principles, see [Sizing](../../sizing.md). ## Cost and latency -The skill orchestrates a multi-step interview plus a parallel sub-agent review round plus a project-manager synthesis pass. The skill passes no model override. Each dispatched sub-agent runs on its own frontmatter tier (so `project-manager`, `junior-developer`, and the other synthesis-heavy agents run on `opus`, while the structured-protocol specialists run on `sonnet`). The interview itself is inexpensive (a model loop with codebase reads). But the sub-agent review round fans out to three to five agents in parallel, each doing its own protocol-driven pass over the draft spec. The synthesis pass on `project-manager` is the most expensive single step. For a medium-complexity feature, expect one interview loop, one parallel review round, and one synthesis pass: roughly equivalent to dispatching five to six sub-agents plus the interview loop itself. The skill is designed for new-feature planning cadence (daily to weekly), not for tight-loop iteration over the same spec. Use `/iterative-plan-review` for that. +The skill orchestrates a multi-step interview plus a parallel sub-agent review round plus a project-manager synthesis +pass.

Use `/iterative-plan-review` for that. ## In more detail -The skill's default posture is to *explore before asking*. If a question can be answered by reading the codebase, project docs, coding standards, ADRs, or existing feature specs, the skill resolves it without troubling you. That source set extends to a read-only tool already available to the session (for example, a connected schema or data-source tool), when one is permitted to the skill. It queries that source the same way it reads the filesystem ones, strictly read-only. The path is gated on the tool actually being available: if none is, the skill falls back to asking you, exactly as before. When a question genuinely requires user judgment, the skill surfaces it with a recommended answer, rationale grounded in evidence, and alternatives considered. You accept, amend, or redirect. - -The specification the skill produces is deliberately behavioral: outcomes, actors, triggers, flows, states, coordinations, edge cases, and user interactions. Technical artifacts (file paths, libraries, data shapes) are admissible only as **evidence** for behavioral decisions, never as the decision itself. - -Once a draft is in place, the skill dispatches three to five specialist sub-agents in parallel to stress-test the spec, always including `junior-developer` as generalist stress-tester. It then runs `project-manager` in synthesis mode to reconcile their input and apply corrections. The output is three cross-referenced files: `feature-specification.md` at the folder root (the canonical behavioral artifact that `/plan-implementation` turns into an implementation plan), plus `artifacts/decision-log.md` and `artifacts/team-findings.md` in a sibling `artifacts/` subfolder. This keeps the primary spec focused on behavior, while decision history and review findings sit alongside it, cross-referenced by `D#` / `F#` ID. +The skill's default posture is to _explore before asking_.

Acceptable evidence includes a user-described need in the source artifact, a named direct dependency, an existing production code path that breaks without it, a regulatory rule that applies today, or a documented incident or measured metric. Behaviors that are interesting but unjustified land in a `## Deferred (YAGNI)` section in the spec with a named *reopen-when* trigger. They are recorded, not silently dropped. The `junior-developer` and `project-manager` agents both apply YAGNI protocols (Evidence Sweep and Evidence Gate, respectively) during the review round, so uncited behaviors that survived the interview get challenged before the spec hardens. +Every behavior, edge case, alternate flow, and coordination committed to the spec must cite at least one piece of +acceptable evidence.

Specifications must reference actors, subsystems, and coordinations *by name*, not by file path or class name. When the spec says *"the invitation service notifies the workspace owner,"* the skill expects the team to have agreed that those names describe meaningful domain concepts. That holds independent of whether the current implementation happens to live in `InvitationService.ts`. +The DDD practice of building a ubiquitous language (the team's shared vocabulary for the domain) informs the skill's +requirement.

It maps a chronological flow of domain events, commands, and actors on a wall full of sticky notes (*what happens, who triggers it, what produces it*). The skill's Design Tree protocol walks a similar shape: foundational decisions (actor, outcome, trigger), then behavioral (flows, states, coordinations), then boundary (edge cases, out of scope).

The skill's interview loop applies a softer version. For every candidate answer, the skill checks the evidence (codebase, docs, ADR) and asks whether the answer resolves the question or masks a deeper one that needs to be surfaced. Questions that survive only because they were repeated, rather than proven, go into Open Items rather than into the spec body. +Root-cause analysis via repeated "why" questioning, popularized at Toyota and adopted widely in software and design +practice.

The skill encodes this as a rule: technical details are admissible in the spec only as evidence for behavioral decisions, never as the decision itself. A spec that says *"use Redis for this"* has overshot into implementation. A spec that says *"the system remembers the last N requests from each actor for five minutes"* has stated a behavior, and Redis becomes one implementation option among several. +Farley's _Continuous Delivery_ and follow-on work on modern software engineering draw a sharp line between specifying +_behavior_ (observable, testable, stable across rewrites) and specifying _implementation_ (ephemeral, refactor-friendly, +subject to change).

The skill's Step 3 (Build the Design Tree) and Step 4 (Interview Loop, One Branch at a Time) enforce this sequencing. The interview does not ask about edge-case error messages before the primary flow is agreed.

Every layer of the system involved for one narrow scenario. A phase does not deliver "all the database work" or "all the API surface." If a phase is not demoable to a real person, it is either too small (merge it forward) or too horizontal (re-think it as a thinner end-to-end strip). -- **Plain language by default.** The outline never names file paths, function or class names, library mechanics, language primitives, or internal flag names. Brand names generalize one level up: *"PostgreSQL"* → *"the database"*, *"NATS"* → *"the events processing system."* A non-technical stakeholder must be able to read the document end-to-end. The only exception is the per-phase "Source citations" line, which may name source-artifact section headings by their actual heading text. -- **Each phase builds on the prior.** As phases ship, the system becomes progressively more capable. Earlier phases stay valid. Later phases enrich what earlier ones delivered. No phase ever invalidates an earlier deliverable. -- **Foundational phases first, only when truly required.** If the demoable feature literally cannot run until a setting, permission model, schema, or configuration foundation exists, the foundation comes first. And even then it must be demoable on its own. *"An admin can edit the new setting and see it persist"* qualifies as a foundation phase. *"We added a database table"* does not. Fold it forward into the first feature slice that uses it. -- **Stable `Phase N` and `OQ-N` IDs.** Phase numbers and open-question IDs are stable for the life of the document. Tickets, threads, and Slack messages cite `Phase 5` or `OQ-3`. The template uses explicit `{#phase-N}` and `{#oq-N}` heading anchors so deep links survive phase renames. -- **IA-reviewed template.** The output template was reviewed by `information-architect` against Rosenfeld & Morville's four IA systems, Mark Baker's "Every Page is Page One," Dan Brown's 8 Principles of IA, LATCH, and Carroll's minimalism. The skill dispatches the same agent at runtime to review each rendered outline before presenting it to you. +- **Vertical slices, not horizontal layers.** A phase delivers a thin end-to-end strip of behavior. Every layer of the + system involved for one narrow scenario. A phase does not deliver "all the database work" or "all the API surface." If + a phase is not demoable to a real person, it is either too small (merge it forward) or too horizontal (re-think it as + a thinner end-to-end strip). +- **Plain language by default.** The outline never names file paths, function or class names, library mechanics, + language primitives, or internal flag names. Brand names generalize one level up: _"PostgreSQL"_ → _"the database"_, + _"NATS"_ → _"the events processing system."_ A non-technical stakeholder must be able to read the document end-to-end. + The only exception is the per-phase "Source citations" line, which may name source-artifact section headings by their + actual heading text. +- **Each phase builds on the prior.** As phases ship, the system becomes progressively more capable. Earlier phases stay + valid. Later phases enrich what earlier ones delivered. No phase ever invalidates an earlier deliverable. +- **Foundational phases first, only when truly required.** If the demoable feature literally cannot run until a setting, + permission model, schema, or configuration foundation exists, the foundation comes first. And even then it must be + demoable on its own. _"An admin can edit the new setting and see it persist"_ qualifies as a foundation phase. _"We + added a database table"_ does not. Fold it forward into the first feature slice that uses it. +- **Stable `Phase N` and `OQ-N` IDs.** Phase numbers and open-question IDs are stable for the life of the document. + Tickets, threads, and Slack messages cite `Phase 5` or `OQ-3`.

The shaping context tells it what should *change* and what should be *deferred*. The skill produces sharper, more decision-ready phase ordering when both are provided. A gap analysis alone produces phases that close every gap in source order. A gap analysis plus *"we need to add role-based authorization that v1 didn't have, and we're deferring URL shortening"* produces phases sequenced for the new product reality. -- **Name divergences from the source up front.** Departures are surfaced once in the executive summary and referenced by name from individual phase entries. If you don't name the divergences, the skill produces an outline that mirrors the source. That is rarely what you want when the source is a *prior* state and the build is a *new* one. -- **Answer the interview questions with the recommendation in front of you.** The skill surfaces each question with a recommended answer grounded in evidence. If the recommendation is right, accept it. That is the cheapest path through the interview. If it's wrong, redirect with the specific reason. The skill folds the reason into the per-phase rationale so future readers see why the build sequenced the way it did. -- **Treat phase 1 as a sanity check.** The first phase is the hardest to get right. If phase 1 is not demoable on its own, the rest of the outline is suspect. The skill probably let a horizontal layer sneak in. Read the phase 1 entry first. If you can't put it in front of a real person and watch something happen, push back and ask the skill to merge it forward into the next demoable slice. -- **Read the executive summary even if you wrote it.** The IA-reviewed template is structured so a stakeholder reading only the executive summary walks away with the shape of the build. Use it as a sanity check on your own framing. If the summary doesn't read well to a non-technical audience, the plain-language-translation step needs adjusting and you should re-run with a sharper audience cue. -- **Pair with `/gap-analysis` upstream.** When the source is a comparison between current and desired state, run `/gap-analysis` first to produce the gap report, then point this skill at the report. The pairing is natural: `G-NNN` gap IDs in the report become source citations on the phase entries that close those gaps. That way the team can always answer *"where did this phase come from."* -- **Pair with `/plan-implementation` downstream.** Once a phase is greenlit, `/plan-implementation` produces a committable implementation plan for that phase alone. The pairing is natural: the phase entry's *"What we build"* and *"Outcome to demonstrate"* become the implementation plan's behavioral spec; *"Preconditions to verify"* become Open Items in the implementation plan. -- **Re-run after the source changes.** A build-phase outline is a point-in-time artifact. It does not auto-refresh. After the source artifact changes (the spec gained sections; the gap analysis ran again with new gaps), re-run the skill. The new outline's `Phase N` IDs are independent of the prior run's. The prior outline stays valid as a snapshot. -- **Use deferrals deliberately.** Anything you defer lands at the bottom of the index with a clear *"(deferred)"* marker and a `Why this is deferred` paragraph. Deferrals are first-class output. They signal *"we considered this and chose not to build it now,"* which is a decision worth recording. Don't list everything that wasn't built. List only what the team explicitly considered and chose to slot for later. +- **Bring shaping context, not just a source artifact.** The source artifact tells the skill what _was_.

Most of the cost lives in the user interview and the IA review of the rendered outline. - -- **The interview.** The skill walks the design tree decision-by-decision, surfacing only the questions that genuinely require your judgment. Most renderings produce three to seven user-facing questions. Each question is presented with a recommendation, so accepting most of them runs cheaply. Redirecting any of them adds one more interview turn. There are no sub-agent dispatches during the interview. It is the skill and you. -- **The IA review.** A single dispatch of the `information-architect` agent against the rendered outline, on its own frontmatter tier (`opus`) since the skill passes no model override. The agent reads the outline once, runs its protocols, and returns findings. Cost is proportional to the outline length. A five-phase outline is cheap; a fifteen-phase outline costs more by token count, not by dispatch count. -- **Apply-findings pass.** The skill applies IA findings in-process. No additional sub-agent dispatch. Plain-language leak findings are required edits. Structural findings are evaluated and applied if they preserve the document's contract. - -For a typical mid-size build (six to ten phases, two to four open questions, a handful of named departures), expect a few minutes of interview-driven question-and-answer with you. Then expect a single IA-agent dispatch and a final summary. The skill is built for periodic, decision-point planning runs: before greenlighting a multi-week build, before a steering-committee briefing, or after a gap analysis surfaces a new picture. It is not built for tight-loop iteration on the same source within a single session. Re-running the skill is appropriate after the source artifact has materially changed. Running it repeatedly against the same inputs in the same session does not produce new insight. +The skill is structured for one decision-point planning run, not for tight-loop iteration on the same source.

Its output is a stakeholder-readable build-phase outline.

Everything after that is rendering and review. +The skill's input is a body of context plus your shaping intent. Its output is a stakeholder-readable build-phase +outline.

Any decision the source already +settles is taken from the source rather than re-asked. -**Interview discipline.** The skill does not batch every question up front. It walks the design tree decision-by-decision: surfacing one or a small batch of questions, capturing the answer, then descending into dependent decisions that the answer enables. It only surfaces the next question when its parent is settled. Every question carries a recommended answer grounded in evidence (source artifact, project context, stated goals) plus one or two alternatives. Accepting the recommendation is the cheapest path; redirecting works fine when needed. +**Interview discipline.** The skill does not batch every question up front.

The skill walks the source section by section and asks, for each cluster of capability: could this be demoed on its own? what does it depend on? is it a foundation that nothing depends on yet, but later phases will? is it a deferral you named? Output of this step is an in-memory list: phase candidates with `kind`, `demonstrability`, and `depends-on` tags. The list is kept in conversation memory, not yet written to file. +**Candidate-phase enumeration.** A candidate phase is a thin end-to-end slice of the system that produces a demoable +outcome.

The list is kept in conversation memory, not yet written to file. **Sequencing rules.** Candidates are ordered by these rules in priority: 1. Dependencies are honored. A phase never appears before any phase it depends on. -2. Earliest demoable feature value is preferred. Among candidates whose dependencies are satisfied, pick the one that delivers the most user-recognizable value first. Foundations come first only when their absence blocks every demoable feature. -3. Foundational phases must themselves be demoable. Re-check each foundation: if the demonstrability statement is *"we added a thing the system uses internally,"* merge it forward into the first feature slice that uses it. -4. Polish-tier work lands later. Branding, expiration controls, audit/log views, view counts, accessibility refinements, internationalization. These enrich a working core rather than make it work, so they sequence after the substantive phases. -5. Deferrals always land at the end of the index with a clear *"(deferred)"* marker. - -The proposed sequence is surfaced to you in one short message (phase number, name, demoable outcome) for confirmation or reordering before any file content is written. - -**Incremental writing.** The skill writes the outline file as soon as the executive summary and phase index are drafted, then updates the file every time a phase is fleshed out. Buffering the entire document in conversation memory and writing at the end is explicitly disallowed. If something interrupts the run, the work-in-progress is preserved on disk. - -**IA review at runtime.** After the outline is fully drafted, the skill dispatches `information-architect` to review the rendered document. The agent applies its full protocol set (Rosenfeld/Morville, EPPO, LATCH, Carroll, Brown) against the rendering. The skill then applies findings. Plain-language leak findings are required edits: technical detail that snuck into the body gets rewritten behaviorally. Structural findings are evaluated and applied if they preserve the document's contract. Polish findings are applied if they tighten the document. Findings you must judge (for example, *"the audience seems mixed; should this be split into two documents?"*) are escalated with a recommendation before finalizing. - -**Anchor stability is part of the contract.** Every phase heading carries an explicit `{#phase-N}` anchor. Every open-question heading carries an explicit `{#oq-N}` anchor. Renaming a phase or question never breaks inbound deep links from tickets, Slack threads, or other documents. If the project's markdown renderer does not support `{#anchor}` heading attributes, the skill falls back to an `<a id="phase-N"></a>` line immediately above the heading. +2.

That evidence can be a behavior you described, a dependency another phase requires, or an existing contract that breaks without it.

The primary plan. Non-obvious claims carry inline markers (for example, `([D-3](artifacts/implementation-decision-log.md#d-3-rollout-strategy))`) linking back to the decision that drove them. Sections include: - - A **Source Specification** section. A markdown link back to the `feature-specification.md`, plus links to the spec's `artifacts/decision-log.md`, `artifacts/team-findings.md`, and `artifacts/feature-technical-notes.md` if those exist. Legacy spec folders may have these files at the folder root instead; the project-manager records whichever path is correct. The `feature-technical-notes.md` entry appears only when the file exists; its absence is not a gap. If the plan was built from conversational context only, the section states that explicitly and summarizes what context was used. - - A **team composition and participation record.** Every specialist the skill engaged, whether they contributed actively or stood down with "no concerns," and a one-line summary of each specialist's input with citation. - - An **implementation approach** section covering architecture and integration points, data model and persistence, runtime behavior, and external interfaces. Technical details are welcome here (this is the *how* document), all grounded in evidence from the codebase, ADRs, and coding standards. - - A **decomposition and sequencing** table. The plan broken into work units sized to ship, each with what it delivers, what it depends on, and how it is verified. - - A **RAID log**, when there is anything to track. Risks (with likelihood, severity, blast radius, reversibility, owner, mitigation), Assumptions (with what-changes-if-wrong), Issues (with owner and next step), and Dependencies (with owner and status). Only the sub-tables with entries appear, and a small plan with no risks, assumptions, issues, or dependencies omits the section rather than rendering empty tables. - - A **testing strategy** grounded in the `test-engineer`'s observable-behavior recommendations (and `edge-case-explorer`'s findings if engaged). Covers test levels, test-doubles posture, and the edge cases requiring coverage. - - A **security posture** section (when `adversarial-security-analyst` contributed) with the concrete threat vectors addressed and the mitigations the plan commits to. Omitted entirely when the feature has no threat surface, rather than rendering a "no security concerns" stub. - - An **operational readiness** section (when `devops-engineer` contributed) covering observability signals, SLO touchpoints, feature-flag strategy, rollout and rollback steps, cost posture, and compliance controls. Omitted entirely when the change introduces no operational surface. - - An **on-call resilience posture** section (when `on-call-engineer` contributed) covering application-source resilience commitments: timeouts and deadlines, retry strategy, idempotency, bulkheads, backpressure, kill switches, graceful degradation, failure-path observability, data integrity, and migration safety.

For each question it records the resolution source (`evidence` found in the loop / `junior-developer reframing` / `user input` / `PM synthesis (Step 8 evidence)` when the PM settled it by re-reading the spec during synthesis rather than in the loop) and the project-manager's next-step recommendation. It also records the decisions the round produced (`Decisions produced:`, backfilled during synthesis) and the plan sections the round changed (`Changed in plan:`, also backfilled). This captures how the plan evolved across rounds without bloating the primary plan file. -- A **summary** returned in-channel. All three file paths, team composition, number of iterations the loop ran before convergence, decisions settled by evidence vs. junior-developer reframing vs. user input, remaining open items and whether they block implementation, and the project-manager's recommendation (ship as planned, hold for specialist handoff, or blocked pending open item). - -The three files interlock through shared IDs.

A specification produced by `/plan-a-feature` comes with a companion `artifacts/decision-log.md` and `artifacts/team-findings.md`, plus Open Items inside the spec. Legacy layouts may have the decision log and team findings at the spec folder root instead; the skill detects and handles both. The specification may also include `artifacts/feature-technical-notes.md`, when `/plan-a-feature` recorded load-bearing mechanics; its absence means none were captured, not that the spec is incomplete. All of that feeds the implementation-planning team's grounding and dramatically reduces the iteration count. -- **Point the skill at a path.** A concrete path to `feature-specification.md` is faster than letting the skill search and confirm. Use the path form in the command: `/plan-implementation docs/features/{name}/feature-specification.md`. -- **Name the team if you know it.** If you already know the feature touches UX, security, and data, say so. The skill always includes `project-manager` and `junior-developer`. Saying *"include these specialists"* lets the skill scope the round-robin tightly from the first iteration. -- **Provide the driving constraint.** Why now: deadline, incident, customer commitment, compliance window? The skill's facilitation is sharper when the project-manager can ground the "driving constraint" section in something concrete rather than inferring from code alone. -- **Trust the loop.** The skill caps iteration by size (1 round small, 2 medium, 3 large) to prevent runaway cycles. Each round is a full facilitation pass: specialists re-engaged as needed, project-manager reconciling, junior-developer reframing open questions. Let the loop run rather than jumping in mid-flight to answer questions that evidence or reframing would have resolved. -- **Answer the escalations succinctly.** When the skill escalates a question, it does so with the specialist(s) who raised it, the evidence considered, junior-developer's reframing, a recommended answer, and the alternatives. Accept or amend the recommendation. Don't re-litigate from scratch. Batched focused escalations are the intended interaction. Not a firehose of raw specialist output. -- **Treat open items as work.** Any item remaining at the end of the loop is either a user-judgment call still awaiting an answer or a genuine blocker the team needs to resolve before implementation. The plan records what would resolve each, so follow-up is concrete. -- **Use the specialist-handoffs-for-implementation list.** The plan names exactly which sibling agents should be re-engaged during implementation, when, and with what input. This is the reader's guide for who gets pulled back in at each stage. Use it instead of re-deriving the specialist fan-out during implementation. -- **Pair with `/iterative-plan-review` if the plan needs further stress-testing.** This skill produces the committable plan. It does not iterate on its own output three times. If you want multi-pass refinement after the plan lands, chain `/iterative-plan-review` next. -- **Re-run after the spec changes.** If the feature specification is updated (new decision, new constraint, new stakeholder), re-run the skill with the updated spec.

For the cross-skill sizing model and design principles, see [Sizing](../../sizing.md). ## Cost and latency -The skill orchestrates a multi-round team conversation. Each round fans out to three to seven specialist sub-agents (plus `junior-developer` and `project-manager`) in parallel and collects their verbatim output. It then runs `project-manager` in facilitation mode to reconcile that input and decide whether to loop again. The skill passes no model override; each sub-agent it dispatches in the iteration loop runs on its own frontmatter tier (synthesis-heavy agents on `opus`, structured-protocol specialists on `sonnet`). The final synthesis pass runs `project-manager` on its default model (`opus`). This is the most expensive single step, but also the step that produces the authoritative plan. For a medium-complexity feature, expect two iterations before the project-manager declares the plan ready, which means roughly ten to twenty sub-agent dispatches plus the `opus` synthesis. The size-based round cap (1 for small, 2 for medium, 3 for large) prevents runaway cycles. The skill is designed for new-feature planning cadence (once per feature, occasionally re-run after spec changes), not for tight-loop iteration. Use `/iterative-plan-review` for that. +The skill orchestrates a multi-round team conversation.

Use `/iterative-plan-review` for that. ## In more detail -The skill's input is the ground truth for *what* the feature does: a `feature-specification.md` produced by `/plan-a-feature`, or an equivalent PRD, design doc, or product brief. Its output is three cross-referenced files, covering *how* to build it, written to the same folder. The skill's defining behavior is the loop. It assembles a team of specialist sub-agents sized to what the feature touches, always including `project-manager` as coordinator and `junior-developer` as generalist stress-tester. It runs rounds of facilitated discussion until the project-manager confirms the plan is ready to commit, or until only user input remains. - -When a decision lacks strong evidence, the skill does not immediately escalate to you. It first asks `junior-developer` to reframe the issue in plain language, because that reframing frequently exposes an unstated assumption or a simpler question the specialists can answer among themselves. Only when evidence and reframing both fail does the skill surface the question to you, with the evidence considered, the reframing, a recommended answer, and the alternatives. - -The `project-manager` owns the final synthesis pass and writes the authoritative plan. The primary artifact (`feature-implementation-plan.md` at the folder root) covers decomposition, sequencing, RAID log, testing strategy, security posture, operational readiness, definition of done, specialist handoffs, and open items. It also links back to the upstream *what* document in a Source Specification section. Decision history and round-by-round iteration history live alongside it, in `artifacts/implementation-decision-log.md` and `artifacts/implementation-iteration-history.md`, cross-referenced by `D-N` / `R#` ID. This keeps the primary plan focused on the implementation narrative, while rationale, rejected alternatives, and discussion history stay one hop away. +The skill's input is the ground truth for _what_ the feature does: a `feature-specification.md` produced by +`/plan-a-feature`, or an equivalent PRD, design doc, or product brief.

Only when evidence and reframing both fail does the skill surface +the question to you, with the evidence considered, the reframing, a recommended answer, and the alternatives. + +The `project-manager` owns the final synthesis pass and writes the authoritative plan. The primary artifact +(`feature-implementation-plan.md` at the folder root) covers decomposition, sequencing, RAID log, testing strategy, +security posture, operational readiness, definition of done, specialist handoffs, and open items. It also links back to +the upstream _what_ document in a Source Specification section. Decision history and round-by-round iteration history +live alongside it, in `artifacts/implementation-decision-log.md` and `artifacts/implementation-iteration-history.md`, +cross-referenced by `D-N` / `R#` ID. This keeps the primary plan focused on the implementation narrative, while +rationale, rejected alternatives, and discussion history stay one hop away. ## YAGNI -A YAGNI sweep runs before the implementation plan is committed. Every plan step, abstraction, infrastructure addition, observability hook, configuration knob, and rollout step must cite acceptable evidence that it is needed *now*. Speculative work moves to a `## Deferred (YAGNI)` section in the plan with a named *reopen-when* trigger. The team agents that participate in the iterative discussion (`project-manager`, `junior-developer`, `software-architect`, `system-architect`, `data-engineer`, `devops-engineer`, `test-engineer`, `edge-case-explorer`) each enforce their own slice of the rule. Between them, that covers premature operational machinery, speculative data machinery, single-implementation interfaces, defensive code at trusted internal boundaries, observability for telemetry that isn't reaching the destination yet, and so on. +A YAGNI sweep runs before the implementation plan is committed.

The skill's Step 4 (Round 1: Parallel Specialist Review) implements round-robin across the specialist sibling agents. Every specialist is asked the specific question their domain answers, in parallel, before facilitation reconciles their input. *"No concerns from my side"* is captured as a valid, recorded answer so participation is never silently assumed. +Round-robin is a facilitation technique in which every relevant participant speaks in turn, deliberately, so quieter +voices are heard before the loudest voice takes the room.

When a decision lacks strong evidence, the skill asks `junior-developer` to restate the issue in plain language before escalating to you. The reframing often exposes the unstated assumption or the simpler question the specialists can answer among themselves. The rubber duck applied to multi-agent specialist facilitation is the resolution step that turns "escalate to user" into "resolve inside the team." +Andy Hunt and Dave Thomas's "rubber duck" practice explains a problem out loud in plain language to surface the gaps in +your own reasoning.

Teammates may disagree with a decision, but once the evidence has been weighed and every relevant voice has been heard, the team commits to executing it. And the dissent, with its cited evidence, is recorded so the decision can be revisited later if evidence changes. The skill's synthesis output records dissent under disagree-and-commit so the plan can reopen cleanly if evidence changes. +Jeff Bezos's _"Have Backbone; Disagree and Commit"_ is the canonical articulation of a principle about disagreement. +Teammates may disagree with a decision, but once the evidence has been weighed and every relevant voice has been heard, +the team commits to executing it.

The skill's output plan requires a testable definition of done, unambiguous acceptance criteria, and a rollback plan. Vague done-criteria are flagged as open items that block synthesis. The project-manager will not declare the plan ready if "done" is still subjective. +Acceptance criteria and Definition of Done are the standard project-management artifacts for making "done" testable +rather than subjective.

They recommend it whenever the feature touches data migration or interface change. The skill's output plan encodes this into the Decomposition and Sequencing table when applicable, because big-bang changes co-deployed with dependent code violate every rollback constraint. +The expand-and-contract pattern (expand the schema / interface / contract, migrate consumers, backfill, flip, contract) +is the default recommendation the skill's `devops-engineer` and `data-engineer` sub-agents produce.

Its output is a single decomposition file. The judgment-heavy work happens in one place: the work item breakdown (Step 5), dispatched to `project-manager`. Everything around it is coordination: locating the plan, resolving where the file goes, inventorying the artifacts an implementer needs, printing the breakdown for visibility, and writing the file incrementally. The skill runs unattended from invocation to the finished file; it stops for you only when there is no plan or context to work from at all. - -**Locating the source.** The skill takes the plan from an explicit path, a feature name resolved to `docs/features/<name>/feature-implementation-plan.md`, or the most recently updated plan when several exist. When there is no plan file at all, it uses inline context instead. It reads the plan plus anything the plan links (a feature specification, a contract file, an ADR). The plan content is the union of those sources. It never fetches a plan from a URL or an external issue tracker. - -**Resolving the output location.** The skill writes exactly one `work-items.md`. It goes in the user-specified folder, the plan file's folder, or next to the source context. When none of those exist, it goes in a best-guess folder of two to four kebab-case words under an existing documentation root. It states which folder it chose and proceeds without waiting for confirmation. If a `work-items.md` already exists in the chosen folder, the skill does not overwrite it and does not stop to ask. It writes to a timestamp-suffixed name instead, and states which file it wrote. The existing file is always preserved. - -**The breakdown.** `project-manager` receives the full plan content, the reference artifact inventory, and the skill's Rules verbatim. Its directive is to draft vertical slices: each work item a narrow but complete path through the appropriate layers, demoable or verifiable on its own, classified HITL or AFK. It prefers AFK, and prefers many thin work items over few thick ones. It returns a numbered list and writes no files. The skill returns that list verbatim, assigns `W-N` IDs, prints the breakdown for visibility, and writes the file without waiting for approval. - -**Incremental writing.** The skill writes the title and intro first, then appends each work item as it is finalized.

On request, it also vendors the three plugin-building skills (`guidance`, `skill-builder`, `agent-builder`) into the current repository under a `plugin-` prefix, plus a path-scoped rule index so the guidance surfaces automatically while you edit skill and agent files. -- **When to use it.** When you need the rules or best practices for a skill, agent, hook, or plugin.

In + Initialization or Update Mode, the three skills vendored into `.claude/skills/` and a rule index at + `.claude/rules/plugin-building-guidance.md`, left staged for you to review. ## Key concepts -- **Three modes, chosen by argument.** `/guidance` with no argument runs **Guidance Mode** (serve the relevant doc). `/guidance init` (or `initialize`) runs **Initialization Mode** (vendor the three skills). `/guidance update` (or `refresh`) runs **Update Mode** (refresh an already-vendored copy). -- **Serve, do not dump.** Guidance Mode reads only the one or two documents that apply to what you are building, then applies them and cites the file. It deliberately does not read every guidance document; that would defeat the progressive-disclosure model the guidance itself teaches. -- **Vendors three runnable skills, under a `plugin-` prefix.** Initialization copies `guidance`, `skill-builder`, and `agent-builder` into `.claude/skills/`, renamed to `plugin-guidance`, `plugin-skill-builder`, and `plugin-agent-builder` so they never collide with this plugin's own slash commands if it is also installed. The repo's users run them as `/plugin-guidance`, `/plugin-skill-builder`, and `/plugin-agent-builder`. The vendored `plugin-guidance` skill is guidance-only (no `init`/`update` modes, since vendoring is a plugin-to-repo operation). Its `references/` directory is the single in-repo copy of the guidance documents, and the two builders are rewritten to point at it. -- **Path-scoped rule index.** Initialization also writes a small index at `.claude/rules/plugin-building-guidance.md` whose `paths:` globs bind it to this repo's skill and agent files. Claude Code loads the index when a matching file is touched. The index points to the vendored guidance documents, so only the guidance the current file needs is loaded, not all of it. -- **No dependency after vendoring.** Once `init` has run, the three skills and their guidance live in the repo. Anyone using the repo can run them and get the right guidance surfaced even if the `han-plugin-builder` plugin is never installed. -- **Standalone and opt-in.** The plugin depends on nothing and is not bundled by the `han` meta-plugin.

Then it runs the interview loop one branch at a time; writes the skill files; runs the full guidance-conformance review; and presents the result with tests.

It is read only when that decision is on the table.

Vendor-neutral, infrastructure-owned by the org. -- **PR-layer review.** AI integrates at the version control workflow rather than the editor, providing cross-repo consistency and pattern enforcement at the merge gate. +Enterprise AI tooling in 2025 and 2026 is built around several distinct kinds of org-level lift.

The research report is the canonical source for these; each example here carries the same evidence framing the research applies. - -**GitHub Copilot Enterprise organization custom instructions.** As of April 2026, generally available. An org admin writes behavioral instructions once in the GitHub admin panel. Every Copilot Chat conversation on github.com, every Copilot code review, and every Copilot cloud agent run inherits them automatically. As of GA the instructions cover github.com surfaces only (Copilot Chat on github.com, Copilot code review), not Copilot in editors like VS Code. The shape of the lift is one admin writing once, with the result propagating to all developers in the org without any developer action. - -**Anthropic Claude Enterprise governance and compliance.** Per Anthropic's own product pages, Claude Enterprise bundles Claude Code and Claude Cowork under a single agreement with workforce-wide deployment, SSO and identity-provider integration, and configurable data retention. That agreement also includes audit infrastructure and policy enforcement covering tool permissions and MCP server configurations across all Claude Code users. It also includes a Compliance API providing programmatic access to conversation content and activity event logs. The shape of the lift is IT and security having a control plane over AI usage that is visible, auditable, and policy-bounded across the org. - -**Org-hosted MCP context servers.** An organization can stand up a Model Context Protocol server exposing internal documentation, code search, runbooks, and ticketing. Any MCP-compatible AI client (Claude Code, Cursor, GitHub Copilot, and others) consumes it. This is the only category that is vendor-neutral: an org's investment is not stranded if the AI tooling changes. It is also the category most directly relevant to Han's audience, because MCP is a first-class deployment primitive in the Claude Code plugin system Han runs on. The shape of the lift is the org owning the index, the access controls, and the update cadence rather than delegating those to a vendor. - -The research report covers three more categories (prompt registries beyond Copilot, org retrieval, model customization, PR-layer review) with named products for each.

Escalate only when a band's signal is clearly present; when a signal is borderline, stay at the smaller band. - -- **Small** *(default)* — a single module or directory, contained surface, no cross-cutting concerns: no security signal, no data signal, no DevOps signal, no system-seam signal. The concurrency signal may be present or absent. -- **Medium** — two or three adjacent subsystems, OR exactly one cross-cutting concern present (one of: security, data, or DevOps signal — a single auth surface, a single data-contract, a single operational surface). -- **Large** — more than roughly a dozen files across multiple subsystems, OR two or more cross-cutting concerns present together, OR a system-seam signal is present, OR `$size` is `large`. - -**Apply the size override.** If `$size` is not `none provided`, use it as the band and skip the signal-based classification above — but still select specialists by signal (a `large` override does not dispatch agents whose domain the code never touches).

Wait for the synthesis layer to return. ## Step 8: Render the Report -Read [references/architectural-analysis-report-template.md](./references/architectural-analysis-report-template.md). Render it into the report draft; you present it after the readability pass in Step 11. Render rules: - -1. **Fill the front matter and "How to Read" frame.** Set the focus area, the chosen size with its one-line justification, the dispatched roster, and git availability. -2. **Carry agent output verbatim.** Each analysis section is the corresponding agent's full output, unedited. The skill writes only the Executive Summary and the section prefaces. -3. **Remove sections for agents that were not dispatched.** Drop the section, remove its line from `sections_included` in the front matter, and replace its promise in the "How to Read" frame with a single line stating it was not part of this run (the same way `gap-analysis` handles optional sections). A small run with no concurrency signal has no Concurrency section; a run with no security signal has no Security section. -4. **Handle the concurrency negative result.** If `han-core:concurrency-analyst` ran but found nothing, keep the section and carry its "no concurrency patterns found" statement — this is a reported result, not an omission. -5. **Resolve system-altitude content.** If `han-core:system-architect` was dispatched, render its `SA#` recommendations in the System-Architecture Recommendations section. If it was not, omit that section and instead render `han-core:software-architect`'s deferred boundary-crossing findings under "System-level concerns deferred", with the one-line note that the user can dispatch `han-core:system-architect` separately for recommendations at that altitude. -6. **Write the Executive Summary last**, after every other section is filled: the focus area and size, the 3–5 most critical findings across all dispatched dimensions, the highest-impact recommendations, and an explicit note on any dimension that was clean or any signalled domain omitted by the band cap. - -**Readability.** Invoke `han-communication:readability-guidance` to surface the shared readability standard into your context. As you write the report's synthesized prose — the Executive Summary, the "How to Read" frame, and the section prefaces — apply that standard: main point first, descriptive headings, one idea per paragraph with the first sentence carrying it, numbered lists for steps and bullets for non-sequential items, and progressive disclosure.

Pass it the draft report text and the named audience: the engineer weighing the module's design and deciding whether to change it; the editor reads han-communication's own canonical rule, so pass no rule path. It preserves every fact and edits **prose regions only** — never inside code fences, pseudocode sketches, Mermaid or other diagram bodies, or finding-ID and `file:line` citation identifiers. Scope its rewrite to the report's synthesized prose (the Executive Summary, the "How to Read" frame, and the section prefaces); leave every analysis section's verbatim agent output unchanged. Apply its rewrite. This pass does not touch the discovery, risk, or architect agent spine (Steps 4–7). +Dispatch `han-communication:readability-editor` with one `Agent` call to audit and rewrite the report draft against the +shared readability standard.

Why it exists, why it works the way it does, why it is the current solution to a real need: that is the spine of the whole document. Everything else the overview carries — what it does, how it flows, where it connects, where to start — flows out of the why and exists to give the reader the context to understand it. "What", "how", "where", and "when" are not dropped or diminished; they are framed by and subordinated to the "why" they serve. BECAUSE a reader who knows what code does but not why it exists cannot make sound decisions about it — the why is the load-bearing understanding, and the rest is scaffolding around it. State the why as a solution to a need, and never invent a business rationale the evidence does not support; when the why can only be inferred, mark it as inferred. -- **The skill orchestrates and synthesizes; the agents discover, validate, then refine.** The skill resolves the target, classifies size, dispatches exploration, and writes the overview. `han-core:codebase-explorer` agents gather the surrounding code and context the synthesis draws on — they do not write the overview. After the draft is written, `han-core:adversarial-validator` re-reads the code to challenge the draft's claims for accuracy, and `han-communication:readability-editor` rewrites the corrected draft against the shared readability standard, preserving every fact; the skill applies the validator's corrections and the editor's rewrite. The skill itself produces the grouping, the charts, the orientation, and the final rewrite. -- **The overview applies the shared readability standard.** As it writes and refines the overview, the skill sources the standard by invoking `han-communication:readability-guidance` (Step 5) and applies it, holding the default audience frame: a capable reader who did not do this work and lacks the author's context. The standard governs how the overview reads (main point first, descriptive headings, one idea per paragraph, progressive disclosure), never whether a required fact about the code appears. Its dedicated `han-communication:readability-editor` pass (Step 7) replaces the older information-architect / junior-developer readability review; the accuracy validator is a separate pass and stays. -- **Read-only, always.** The skill explains; it never edits the target. It writes only its own scratch overview file. BECAUSE the job is understanding, not modification — this keeps the skill safe to point at unfamiliar code. -- **Accurate to the code, always.** Every claim the overview makes — the why it states (grounded in commit and PR/issue intent, comments, and what the code visibly does toward a goal), what the code does, each flow step, each named entry point, each change grouped by intent — must be grounded in the actual code and its intent, never inferred past the evidence or invented.

Fold anything worth keeping into the intro sentence. - -**Lead with the why, and let everything else flow from it.** The first section after the intro answers *why this code (or this change) exists* — the real problem it solves or the goal it accomplishes for the business or a user, then why it works the way it does and why it is the current solution to that need. Tell the why as a solution to a need, not as technical mechanics. Then frame every section that follows as serving that why: the flow shows how the code delivers on it, the context shows what it depends on to meet the need, the handoff shows where to start working on it. When the why is not recoverable from the code and its intent (commit messages, PR/issue text, comments, naming, tests), state what the code demonstrably does toward a goal and mark the inferred why as inferred — never invent a business rationale the evidence does not support. - -**Code mode** renders, in order: the title and intro paragraph; a coverage note **only if** coverage was partial; **Why it exists** (the problem the code solves or goal it serves, then briefly what it is and why it works the way it does — all flowing from the why); **Main flow** (a Mermaid chart with a one-line scope label, read as how the code delivers on the why); **Context and uses** (context and uses kept distinguishable, framed as what it depends on to meet the need and where that need is served from); **Where to start** (the concrete entry points the reader opens first). - -**PR mode** renders, in order: the same title and intro paragraph; the same conditional coverage note; **Why this change exists** (the problem the change solves or goal it advances, then briefly the bottom line of what it does); **Changes by intent** (grouped by the reader-visible outcome each group delivers — the why each group serves — not by file, layer, or author motivation; a single logical change is one narrative with no grouping header); **How the change flows** (a Mermaid chart with a scope label, placed after the grouped changes BECAUSE the reviewer must know what changed before that chart is meaningful); **What to watch when reviewing** (navigational only — where the change is hardest to follow and why; never a quality or risk judgment). - -**Place any captured screenshots inline next to the text they illustrate** — embedded as `![caption](url)` directly under the Changes-by-intent item or the flow step they depict, BECAUSE a visual next to its description spares the reader a trip back to the PR.

The next step reviews and rewrites this file in place. ## Step 7: Validate Accuracy, then Rewrite for Readability -This step runs two distinct passes, in order: the accuracy validator first, then the readability rewrite. Accuracy is settled before readability so the editor never polishes a claim that is about to be cut. - -**Pass 1 — accuracy.** Dispatch `han-core:adversarial-validator` over the draft overview. Pass it the scratch-file path and the resolved target (and, in PR mode, the changed-file set) so it knows what to re-read. - -- **`han-core:adversarial-validator`** — assume every claim the overview makes about the code is WRONG until the code and its intent prove it right. Re-read the target (and the diff, in PR mode) and challenge each material claim, starting with the one the document leads on: is the stated **why** — the problem the code solves or the goal it serves — grounded in real evidence (commit messages, PR/issue intent, code comments, what the code visibly does toward that goal), or is it an invented business rationale, and where the why is inferred rather than stated, is it marked as inferred; does the code actually do what *Why it exists* / *Why this change exists* says; does the **Main flow** / **How the change flows** chart match the real control flow, in the right order, with no invented or missing steps; do the named **Where to start** entry points exist and are they the right ones; does each **Changes by intent** grouping describe what that change actually does and the why it claims to serve. Surface every claim that is unsupported, overstated, contradicted by the code, or hallucinated — the why most of all, since it is the load-bearing claim — citing the file, line, or commit that disproves it. **Validate the accuracy of the description only — do not assess the code's quality and do not raise findings about the code itself.** Return a list of inaccurate or unsupported claims, each with the corrected fact or a note that the claim should be cut. - -Apply the validator's corrections to the scratch file first: fix or cut every claim it disproved. A sentence that reads beautifully but describes a flow the code does not follow must still be corrected or removed. If validation removed so much that coverage is now meaningfully partial, add or update the coverage note. - -**Pass 2 — readability rewrite.** Dispatch `han-communication:readability-editor` over the corrected draft. This dedicated pass replaces the older information-architect / junior-developer readability review; the deliverable gets one readability rewrite, not two overlapping reviews. - -- **`han-communication:readability-editor`** — rewrite the overview against the shared readability standard for the default reader (a capable reader who did not do this work and lacks the author's context), preserving every fact. Pass it the scratch-file path; the editor reads han-communication's own canonical rule, so pass no rule path. It operates on **prose regions only**: it does not touch the Mermaid chart bodies, code fences, or the embedded screenshot markup, and it leaves every named file, symbol, and entry point exact. It applies the rewrite to the scratch file in place and returns a rubric verdict and a fact-preservation ledger. Tell it: **rewrite the overview document for readability only — do not review the underlying code, and do not raise findings about it.** This skill makes no quality judgment about the code; the validator guards truth, the editor guards clarity, and neither crosses into evaluating the work itself. - -Keep the spec-content discipline through both passes: the result is still an orientation aid with no quality findings, led by the why with everything flowing from it, minimal technical detail in the why/flow/context sections, and concrete entry points in the handoff section. - -**Readability self-check.** After the rewrite, run the standardized readability self-check (the shared standard is in your context from `han-communication:readability-guidance`) over the overview's prose regions only — never inside the Mermaid chart bodies, code fences, screenshot markup, or file/symbol references.

Exhaust inference before asking; this is a hard dependency, not a discretionary checkpoint. ## Step 2: Build the BDD Test List -Turn the requested feature or behavior into a test list (Kent Beck's "test -list" pattern). Each item is one observable behavior, phrased as a behavior -sentence, not as an implementation note. "Returns the unrounded fee for a -sub-dollar charge" is a list item; "use a BigDecimal" is not. Follow -[references/bdd-framing.md](./references/bdd-framing.md) for how to phrase and -name behaviors, and which test-naming convention to adopt (the project's -existing convention and any discovered coding standard win over a literal -"should" default). - -**Fixing existing broken behavior is a regression test, not a bug-asserting -test.** When the work fixes broken behavior, the list item names the *desired -correct* behavior, not the current broken one: "returns the rounded total for a -refund" (red now because the bug is present, green once the fix lands), never -"raises ArgumentError on a refund" — a test that asserts the error the bug -produces passes while the bug is present and breaks when you fix it, locking the -bug in. The regression test asserts what the code *should* do. The boundary: -asserting that the code raises is the *correct* test when raising is the -specified desired behavior (raise on invalid input); it is wrong only when the -raised error *is the bug being fixed*. - -Order the list outside-in by user value: the next item is the most important -thing the system does not yet do. When one behavior expands into several -candidate tests (the empty case, the single case, the many case, the -boundaries), order those tests simplest-first — Zero → One → Many — so each -test forces the smallest generalization of the code. The ranking behind that -order is in [references/test-selection.md](./references/test-selection.md); -pull it when the order is not obvious. For an item that is **user-observable -behavior at a system boundary**, write the outer acceptance test for it *first* -(it will be red until its inner behaviors exist) and record it as the outer -loop for that item. For internal or utility behavior with no meaningful system -boundary, the outer acceptance test is optional; the inner loop alone is -correct. - -Apply YAGNI to the list itself. A scenario earns a place only with evidence it -is needed now (a user-described need, a named dependency, an existing code path -that breaks, a regulation, a real incident). Scenarios that fail the evidence -test go to a deferred list with the trigger that would reopen them. Do not pad -the list for symmetry or completeness. - -Report the test list to the user.

Detection: "framework handles this" without a version or documentation reference. -- **Priority Inflation**: Explorer rates many edge cases as Critical without distinguishing likelihood. Detection: Critical count exceeds High count, and Critical findings include scenarios requiring exotic inputs. -- **Untraceable Scenario**: Explorer describes an edge case scenario without citing the specific code path that would be affected. Detection: finding has no file path or line number for the affected code. -- **Speculative Edge Case (YAGNI)**: Explorer raises an edge case for input shapes the code doesn't actually receive, code paths that don't exist yet, hypothetical adversaries the code does not face, or boundary conditions that no realistic caller produces. Per [`han-core/references/yagni-rule.md`](../references/yagni-rule.md), an edge case is worth exploring only when (a) a real caller could realistically produce the input, (b) the failure mode has plausible production trigger, or (c) the edge case is critical-path correctness regardless of caller (data integrity, security, isolation). Detection: edge case is justified only by "what if a caller…" without identifying a real caller, the input shape requires construction no real upstream produces, the failure mode has no plausible production trigger, or the edge case is symmetry-driven ("we covered the lower bound, so we should cover the upper bound" when only one bound is reachable). Remediation: cite a real caller that produces the input, demote to Dropped Edge Cases with the trigger that would justify revisiting (a real customer hits it, a new caller is added that produces the shape), or replace many speculative low-bound/high-bound items with one durable boundary test that catches the realistic failure modes. +- **Dimension Checklist Padding**: Explorer lists an edge case dimension as "not applicable" without checking whether + the code actually touches that dimension.

When you see one, name it. - -- **Missing or incomplete timeout.** Any outbound call (HTTP client, RPC, database query, queue read, cache read, lock acquisition, file I/O) without a finite timeout, or with a timeout that does not cover DNS resolution or TLS handshake. Detection: client construction with default timeouts, no explicit timeout parameter, infinite or very large default. Failure mode: Blocked Threads → Cascading Failure → thread pool exhaustion. -- **Retry without exponential backoff and jitter.** A retry loop with linear or no backoff, or backoff with no randomization. Detection: a loop with `sleep(constant)` or `sleep(base * 2^n)` on retry without `jitter`/`random`. Failure mode: Retry Storm → self-inflicted DDoS on a recovering dependency. -- **Cascading retries.** Multiple layers of retry stacked along a call chain (client retries × middleware retries × handler retries) without coordination. Detection: retry logic at more than one layer of the same call path. Failure mode: 243× amplification per Brooker; retry storm. -- **Non-idempotent operation in a retry path.** A handler with side effects (mutation, charge, notification, write) invoked through any system that retries on failure (message queue, webhook, scheduled job, RPC client with retry) without an idempotency key check. Detection: a write/mutation without a deduplication guard in a path that is provably retryable. Failure mode: duplicate side effects discovered in postmortem. -- **Catch-and-swallow / empty handler / debug-only logging in catch.** A catch block that is empty, only logs at a level that does not fire in production, or returns a default without surfacing the error. Detection: `catch (Exception e) {}`, `catch { log.debug(...) }`, catch returning `null` or `[]` with no telemetry. Failure mode: Gray Failure — application returns wrong answers, monitoring shows green. -- **Unbounded queue, buffer, or result set.** Any in-memory queue or buffer with no size limit; any database query with no `LIMIT` that returns small sets in staging but unbounded sets in production. Detection: queue/channel/buffer construction without max size; query without `LIMIT` against a growable table. Failure mode: Queue Runaway, OOM-kill, slow memory leak. -- **Missing backpressure / open-loop consumer.** A consumer that accepts work faster than it can process with no signal upstream to slow down. Detection: no rate limiting on inbound producer; memory growth proportional to producer throughput; no queue-depth or consumer-lag observation. Failure mode: bistable system per Brooker; queue runaway. -- **Blocking I/O in async execution context.** Synchronous blocking operation (`time.Sleep`, `.Result`, `.GetAwaiter().GetResult()`, synchronous DB call, `requests.get` inside `asyncio`, `fs.readFileSync` in Node.js event loop) inside an async or event-loop context. Detection: blocking call inside a function marked `async`, `goroutine`, or a thread-pool task. Failure mode: Thread Pool Starvation — low CPU, no exceptions, latency climbs to minutes at moderate concurrency. -- **Missing bulkhead / undifferentiated concurrency limit.** Shared thread pool, shared connection pool, or shared semaphore across all dependencies, so that one degraded dependency starves all the others. Detection: single global `http.Client`, single global database pool serving all dependencies, no per-dependency concurrency cap. Failure mode: Cascading Failure; a single slow dependency takes the whole service. -- **Hardcoded environment assumption.** Hostnames, ports, credentials, paths, timeouts, or sizing values hardcoded for one environment. Detection: literal hostnames, ports, or URLs in source files; hardcoded credential strings; `if (NODE_ENV === "production")` branches that gate business behavior. Failure mode: configuration error — the largest single category in postmortem databases. -- **Schema migration co-deployed with dependent code.** A `DROP COLUMN`, rename, or type change in the same deploy as the code that stops using the dropped field. Detection: a migration file in the diff that removes a column or changes its type, plus application code in the same diff that no longer references it. Failure mode: rolling-deploy outage — old pods query the dropped column for the window of the rollout. -- **Missing correlation ID propagation.** A handler that receives an inbound trace context but does not propagate it to outbound calls and log events. Detection: log statements with no correlation field; outbound clients constructed without the inbound context; new log writer with no trace-id binding. Failure mode: incident MTTR multiplied because operators cannot correlate across services. -- **Assuming a dependency is always available.** Code that calls a dependency (cache, auth service, feature-flag service, external API) with no fallback, no circuit breaker, no degraded-mode response. Detection: no error branch for the dependency call other than "throw"; no `if dependency.down: …` path. Failure mode: Integration Points anti-pattern — when the dependency degrades, the calling service hangs or throws an unhandled exception per request. -- **Missing rate limiting on outbound fan-out.** A handler that fans out to N downstream calls per request with no limit on N or on outbound concurrent connections. Detection: a loop over an input set making one call per item without `Semaphore` / `errgroup` size limit / equivalent. Failure mode: fan-out amplification; connection pool exhaustion. -- **Eventual-consistency violation.** Code that assumes read-your-own-writes or monotonic-read semantics on a store that does not guarantee them. Detection: a write immediately followed by a read of the same key from a replica or cache; assumption that a recently written value is visible. Failure mode: phantom failures that confuse on-call investigation. -- **Data integrity bug.** Silent data truncation (database column shorter than the value), integer overflow on stored values (32-bit ID approaching exhaustion), floating-point rounding in financial paths (cumulative loss), character encoding corruption (mojibake on round-trip), partial-write corruption (unfinished write read as committed). Detection: short column types with no explicit length validation; arithmetic on monetary values in float; encoding boundaries with no explicit conversion; write paths that do not use the storage layer's atomic write primitive. Failure mode: data corruption — invisible until downstream inconsistency surfaces; among the worst 3am pages because rollback may not be sufficient to recover. -- **Kill switch absent on a risky new code path.** A new feature, a new dependency call, or a new code path with no operationally-flippable disable mechanism. Detection: a new branch or new external call wired in unconditionally with no feature flag, ops flag, or kill-switch check. Failure mode: when the new path fails in production, the only mitigation is a redeploy or rollback — minutes-long MTTR instead of seconds-long. -- **ODD gate failure (Majors).** A change for which the answer to "how will I know when this isn't working?" is not present in the diff. Detection: a new code path with no log statement, no metric increment, no SLI contribution, no alert, no observable surface beyond exceptions. Failure mode: the next incident on this path is a gray failure — users see the problem, the team finds out from a support ticket. +Each anti-pattern below is a code-level smell with a named detection signal and a named production failure mode.

Is it derived from the downstream p99/p99.9? -- **Deadline propagation.** Is the inbound deadline / context forwarded to this call, or does the call use its own deadline disconnected from the caller's? -- **Retry coverage.** If the call retries (in the client SDK, in middleware, or in the calling code), what is the retry policy?

Emit a metric? Re-raise or wrap?

When a finding shows a module with multiple responsibilities, recommend splitting along responsibility boundaries. -- **Open/Closed Principle (OCP)** — Modules should be open for extension but closed for modification. When a finding shows code that must be modified to add new behavior, recommend extension points. -- **Liskov Substitution Principle (LSP)** — Subtypes must be substitutable for their base types. When a finding shows type hierarchies where substitution breaks callers, recommend interface redesign. -- **Interface Segregation Principle (ISP)** — Clients should not be forced to depend on interfaces they don't use. When a finding shows fat interfaces, recommend splitting into focused interfaces. -- **Dependency Inversion Principle (DIP)** — High-level modules should not depend on low-level modules; both should depend on abstractions. When a finding shows business logic depending on infrastructure, recommend abstraction boundaries. -- **High Cohesion** — Related functionality should be grouped together. When findings show scattered related code, recommend consolidation. -- **Loose Coupling** — Modules should minimize dependencies on each other. When findings show tight coupling, recommend dependency reduction through interfaces, events, or architectural boundaries — *within the codebase*. -- **Hexagonal / Ports & Adapters** — Business logic at the center; I/O, framework, and infrastructure at the edge, connected through ports.

Detection: + the recommendation cites no upstream finding requiring this specific topology today, the proposed split has no + measured cross-context friction, the integration is justified by "for future flexibility" / "best practice" / "when we + scale" rather than a real ownership conflict or failure mode the team is actually experiencing, or a strictly simpler + topology (keep it in-process, single bounded context, sync call with idempotency on the existing endpoint, etc.) would + satisfy the same upstream finding. Splitting a healthy monolith into a distributed monolith is the canonical example. + Remediation: cite the in-scope evidence forcing the topology change now, recommend the strictly simpler topology + instead, or defer the recommendation under YAGNI with the trigger that would justify revisiting. ## Design Principles Ground every recommendation in one or more of these principles. Name the principle explicitly. -- **Bounded-Context Integrity** — each bounded context owns its model and ubiquitous language; concepts that mean different things in different contexts are not shared as a single model. When a finding shows one model carrying multiple meanings, recommend splitting along the context seam. -- **Context-Map Relationships** — every integration between contexts is an explicit relationship (partnership, customer-supplier, conformist, ACL, shared kernel, OHS, published language, separate ways). The choice is driven by the teams' power and collaboration dynamics, not convenience. When an integration is ambiguous, recommend the relationship that matches the real dynamics. -- **Anti-Corruption Layer at the Seam** — a context that must integrate with a legacy or externally-owned model protects its ubiquitous language by translating through an ACL. When a finding shows a context conforming to a foreign model it does not want, recommend introducing an ACL. -- **Sync-vs-Async Placement** — synchronous request/reply is the right choice only when the caller cannot proceed without the answer and the latency is acceptable. Everything else benefits from asynchronous integration (domain events, integration events, event-carried state transfer, sagas). When a finding shows synchronous coupling where eventual consistency is acceptable, recommend async. -- **Data Ownership** — each concept has exactly one system of record. Other contexts may hold replicas or projections but do not write. When a finding shows multiple writers to the same concept, recommend consolidating ownership and shifting other contexts to readers or requesters. -- **Idempotency and Delivery Semantics** — at-least-once delivery is the default; exactly-once is almost never achievable end-to-end. When a finding shows a consumer that cannot tolerate duplicate delivery or a producer with no idempotency key, recommend idempotent consumers and idempotency keys on the wire. -- **Failure Domain Containment** — a failure in one service must not cascade across the whole system. Timeouts, retries, circuit breakers, bulkheads, backpressure, and dead-letter queues place the blast radius intentionally. When a finding shows unbounded coupling to a failure, recommend a containment mechanism. -- **Trust Boundary Placement** — authentication, authorization, and input validation live at the edges of a trust domain, not re-implemented at every hop. When a finding shows authz logic duplicated or missing at an edge, recommend a trust-boundary adjustment. -- **Organizational Fit (Conway's Law)** — a system's integration shape reflects the team shape. When a finding shows an integration that does not match the owning teams (e.g., conformist where a partnership is needed, or shared kernel between teams with diverging priorities), recommend either the relationship change or the team-shape change. +- **Bounded-Context Integrity** — each bounded context owns its model and ubiquitous language; concepts that mean + different things in different contexts are not shared as a single model.

Produce no research report. -- **Hybrid.** If the request contains an answerable open-ended research question *and* asks for a sibling's output ("research caching options and write the standard for the one I pick"), run the research portion to a full report, then name the sibling for the rest.

If nothing research-shaped remains once the sibling request is set aside, treat it as out of scope and redirect entirely. -- **Compound.** If the question bundles more than one independent research thread (threads that would each produce their own report), name the threads you found, ask the user which to run first, and defer the rest. Do not merge independent threads into one report. +- **Out of scope.** If the request is a bug to diagnose, a feature to specify, a coding standard to set, two concrete + artifacts to compare, or an existing module's architecture to assess, name the correct sibling skill (`investigate`, + `plan-a-feature`, `coding-standard`, `gap-analysis`, `architectural-analysis`), explain in one sentence why it fits + better, and stop.

Three signals drive the band: -- **Options signal:** how many distinct viable approaches are genuinely in play. A "how does X work" question has none; "should I use A or B" has two; "what are all my options for Z" may have many. -- **Domain signal:** how many separate technical domains the question spans (one focused topic vs. several interacting concerns). -- **Reach signal:** how wide the evidence reach must be — provided material or a single source only, vs. codebase plus the open web plus provided material. +- **Options signal:** how many distinct viable approaches are genuinely in play.

Escalate only when a band's signal is clearly present; borderline signals stay +smaller. -- **Small** *(default)* — one domain, few or no competing options, narrow reach (a focused "how does X work" or "is A or B better for this one thing"). +- **Small** _(default)_ — one domain, few or no competing options, narrow reach (a focused "how does X work" or "is A or + B better for this one thing"). - **Medium** — two to three domains, several competing options, or codebase-plus-web reach. - **Large** — many options across multiple domains, or an explicit request for full breadth, or `$size` is `large`. -**Apply the size override.** If `$size` is not `none provided`, use it as the band and skip the signal-based classification — but still pick angles by signal (a `large` override does not run a codebase angle when there is no codebase, or an option-comparison angle when there are no options). A conversational override ("research this broadly") is equivalent to `$size`. +**Apply the size override.** If `$size` is not `none provided`, use it as the band and skip the signal-based +classification — but still pick angles by signal (a `large` override does not run a codebase angle when there is no +codebase, or an option-comparison angle when there are no options).

Emits `A#` artifacts, plain-language results, indexed `O#` options when applicable, and a recommendation. -- `han-core:adversarial-validator` — challenges the evidence, the options framing, the recommendation, and the integrity of the evidence-gathering.

Wait for the entire wave to return before proceeding. ## Step 6: Compile the Sources Registry -Collect the full verbatim output from every agent. Consolidate every information source used that is relevant to the results into a single indexed Sources registry (`A1, A2, …`), merging duplicates. Each entry carries: a link or repository location the reader can independently check (a source URL for web, `repo/path:line` for codebase, a precise reference for provided material); a retrieval date for web sources; the trust class (codebase, web, or provided) per the canonical evidence rule in [`../../references/evidence-rule.md`](../../references/evidence-rule.md); a plain-language summary of what the source says that is relevant (a one-line cell by default; a full prose summary for the sources the recommendation rests on); and an evidence status. - -Apply the evidence rule defined in [`../../references/evidence-rule.md`](../../references/evidence-rule.md) for the trust-class vocabulary, the web-source corroboration gate, conflict surfacing between sources, the codebase-as-current-state-anchor rule, and the no-evidence labeling pattern. In exploratory mode an unevidenced reasoning step may inform the recommendation but is recorded as its own labeled entry, never disguised as a sourced artifact. Every entry gets an ID that Research Results, Options, and the Recommendation cross-reference inline, so every conclusion traces to its sources — every `A#` cited inline must resolve to a registry entry. Render the registry as a compact table by default (ID, title/source, link or location, retrieval date for web, trust class, evidence status), reserving a full prose summary for the sources the recommendation rests on. The Sources registry is always produced, even for a minimal run; what scales with the band is each entry's depth, not whether the section appears. +Collect the full verbatim output from every agent.

Upload is adaptive: by default each PNG is written directly to the default branch via the GitHub Contents API, but if that branch is protected and rejects the direct write (HTTP 409), the script falls back to committing the PNGs to an assets branch, opening a pull request, and printing the PR URL. The embedded image URLs always name the default branch, so on the PR path the inline designs render once that assets PR merges — the issues are still created immediately. Overwrites existing files cleanly and, on re-run, reuses the assets branch and open PR — but only a branch it created for this feature (one already carrying the feature's `issue-assets/<feature-slug>/` tree); a same-named branch it does not own is refused rather than committed onto. -2. **`scripts/create-issues.sh`** — creates one GitHub issue per `## <SYM-N>` slice in file order (blocker-first), unassigned and unlabeled by default.

Keep each node as a behavioral question with a candidate +answer. ## Step 4: Interview Loop — One Branch at a Time For each decision in dependency order: -1. **Try to resolve it from evidence.** Re-check the codebase, docs, standards, ADRs, and already-settled decisions. If a read-only tool that authoritatively answers the question is available to this session (a connected schema, data-source, or similar read-only tool) and permitted to this skill, query it before surfacing the question — the same answerable-from-a-source discipline already applied to static sources, extended to connected ones. Gate it on availability, not judgment: if such a tool is available, use it; if none is available (including because it is not permitted to this skill), ask the user as today. Keep it read-only — no writes, no state changes. If the answer is clear from evidence, record it in the spec with the evidence citation and move on — do not ask. -2. **If evidence is insufficient, draft a recommended answer.** Ground the recommendation in whatever evidence is available (prior decisions, conventions, stated goals, user's framing). State the recommendation, the rationale, and the alternatives considered. -3. **Apply the YAGNI evidence test before surfacing.** A decision that exists only for "completeness", "for future flexibility", "we might want to", "best practice", or symmetry with another feature is a YAGNI candidate per [../../references/yagni-rule.md](../../references/yagni-rule.md). When no accepted evidence (user-described need, named direct dependency, existing code path, applicable regulation, documented incident/metric) supports the decision, the recommended answer is "defer this to the spec's `## Deferred (YAGNI)` section with the reopening trigger named" — surfaced to the user with rationale like any other recommendation. When evidence does support the decision, apply the simpler-version test: is there a strictly simpler behavior that satisfies the same evidence? If yes, recommend the simpler behavior. -4. **Surface to the user only if the decision genuinely needs their judgment.** Present the recommendation, rationale, and alternatives. Allow the user to accept, amend, or redirect. Capture their answer verbatim in the spec. -5. **Descend.** Once a decision is settled, evaluate whether any dependent decisions are now resolvable from evidence (they often are).

Do not batch every question upfront; ask +as the tree unfolds, because later answers often resolve earlier uncertainties. ### Routing implementation-level details -When settling a decision surfaces an implementation mechanic (a specific library, language primitive, data shape, protocol detail, concurrency choice, or file-level pattern), classify the mechanic BEFORE writing the spec sentence and route it to the correct home: - -1. **Does the mechanic change what the user or system observably experiences** — ordering, durability, delivery guarantees, consistency, visibility timing, error-visibility? If yes, settle the behavioral consequence in the spec and capture the enabling mechanic as a `T#` candidate (see capture discipline below). The spec sentence must state the behavioral consequence on its own; the `T#` link only supplies the mechanic.

Also read the lightweight project context: -- CLAUDE.md and any `project-discovery.md` if they exist — they may surface conventions for where this kind of document lives, what tone the team uses, or what other planning docs already exist. -- Existing planning/phasing/roadmap documents in the chosen output folder or its parent (use Glob) — the team's prior format precedent informs the reading-experience choices in Step 6. -Record what was found and what was not.

It still must be demoable on its own (the operating principle holds — "I can edit the new setting and see it persist" qualifies; "we added a database table" does not).

Candidates that exist only for "completeness", "for future flexibility", "best practice", or symmetry with another effort go straight to the deferred-phases list with the reopening trigger named.

Full: has rejected alternatives, evidence beyond the user's framing or the source spec's commitments, was changed across rounds, has dependent decisions, or has recorded dissent. Trivial: settled directly by the user, the source spec, or an obvious convention. Full decisions go under `## Full decisions` with the structured fields (rationale, evidence, rejected alternatives, specialist owner, revisit criterion, dissent, `Driven by rounds:`, `Dependent decisions:`, `Referenced in plan:`). Trivial decisions go under `## Trivial decisions` as a one-line bullet (`D-N: {title} — {outcome}. — Referenced in plan: {sections}.`). The D-N counter is shared across both sections, and every plan inline link still resolves to a D-N whether full or trivial. -2. **Write `feature-implementation-plan.md`** — the primary plan covering Source Specification, Outcome, Context, Team Composition, Implementation Approach, Decomposition and Sequencing, RAID Log, Testing Strategy, Security Posture, Operational Readiness, On-Call Resilience Posture, Definition of Done, Specialist Handoffs, Deferred (YAGNI), Open Items, and Summary. Several sections are **lazily created** — write each only when it has real content and omit it entirely otherwise, never rendering an empty stub: `RAID Log` (include only the sub-tables that have entries; omit the section when all four are empty), `Security Posture` (only when there is a threat surface or `han-core:adversarial-security-analyst` contributed), `Operational Readiness` (only when there is an operational surface or `han-core:devops-engineer` contributed), `On-Call Resilience Posture` (only when there is a resilience surface or `han-core:on-call-engineer` contributed), and `Deferred (YAGNI)` (only if at least one item was deferred under the YAGNI rule, per Step 7.5's ledger and PM's own application of the rule during synthesis). Omitting a lazy section records the judgment that the surface is genuinely absent, not a skipped concern — confirm before omitting. This keeps a small plan proportionate: sizing already caps the team and rounds, and lazy sections stop a small plan from carrying empty operational scaffolding. For each deferred item, record: the item, why deferred (which gate failed), the reopening trigger, and the source (specialist or round that proposed it).

Additionally, focused context outperforms accumulated context: performance peaks at roughly 15-40% context +window utilization — enough grounding to prevent hallucination, not so much that relevant tokens get buried in noise. +These effects are the mechanism behind the recency bias rule in workflow-patterns.md and the "don't bury critical +instructions" rule in writing-effective-instructions.md. ## The Rules ### Rule: Every token must earn its place -Before adding content to a SKILL.md, its frontmatter, or its references, ask: does this token improve the skill's output? Content that doesn't improve output — filler prose, redundant explanations, restated context that the model already has — doesn't just take up space.

Emits structured output with `git-available`, `branch`, `default-branch`, and either a `changed-files-start`/`changed-files-end` block or `changed-files: none`.

The calling skill does almost no work of its own. Han ships two live examples, and they run reliably: -- `han-atlassian:plan-a-feature-to-confluence` validates its inputs, runs - `han-planning:plan-a-feature` to a temporary folder, gets the user's review and - publish choice, then hands every file to `han-atlassian:markdown-to-confluence` - to publish. -- `han-atlassian:project-documentation-to-confluence` does the same shape with - `han-core:project-documentation` feeding `han-atlassian:markdown-to-confluence`. +- `han-atlassian:plan-a-feature-to-confluence` validates its inputs, runs `han-planning:plan-a-feature` to a temporary + folder, gets the user's review and publish choice, then hands every file to `han-atlassian:markdown-to-confluence` to + publish. +- `han-atlassian:project-documentation-to-confluence` does the same shape with `han-core:project-documentation` feeding + `han-atlassian:markdown-to-confluence`. -These work because they follow a disciplined shape.

Do not -summarize, trim, or reinterpret it. The goal is that the sub-skill runs exactly as -it would if the user had invoked it directly. `plan-a-feature-to-confluence` is -explicit about this: it forwards "all provided context verbatim" so the planning -skill's interview, review team, and synthesis all run normally. +When you invoke the sub-skill, pass the user's request, the `size` argument, known constraints, and the relevant +conversation context through unchanged.

The Confluence orchestrators tell `plan-a-feature` to -write under `/tmp/` rather than into the repo, and not to prompt the user to -choose an output location, because the orchestrator owns that decision.

Counter it directly: end -the step with an explicit instruction to proceed to the next step. Never rely on -implicit continuation.

Use context injection to detect config files (CLAUDE.md, project-discovery.md). 2. Read the file directly and extract the values you need in your own step logic. 3. Fall back to conventional defaults when a value is not found. -This eliminates the forked sub-skill entirely, and with it the `api_retry` -interaction and the early-exit risk.

The motivating case is a guidance skill that reads one canonical +copy of a writing or review standard and surfaces it into whichever skill is about to produce output, so the standard lives in one place instead of being vendored into every plugin that needs it. Three properties separate this from the data-fetch pattern you should avoid: -1. **It is inline, never `context: fork`.** The documented early-exit failure is - fork-specific: a forked sub-skill returns a value, an `api_retry` fires, and - the caller anchors on that value as its final answer. An inline sub-skill - renders into the shared context and never returns a value to anchor on. A - dedicated spike ran a heavy consumer skill through an inline guidance skill - many times, including a worst-case run with every continuation guardrail - removed and a deliberately final-sounding closing line, and the caller resumed - and finished every time with no early exit. The forked variant of the same - skill was disqualified for a separate reason: the fork isolated the guidance - so its content never reached the caller. -2. **It surfaces a whole standard, not a few values.** Retrieving a docs - directory or a test command is still data-fetch; do that inline (above).

Keep an explicit "proceed to the next step" instruction after the invocation as cheap insurance, even though the spike completed without it. -One honest limit on that evidence: the spike could not induce a real `api_retry`, -which is the specific trigger of the forked failure. The worst-case run removed -the mitigation `api_retry` is said to defeat and still held, so treat this -exception as reliable under adversarial same-context testing, not as proof the -failure can never occur.

Derive the feature name from the source spec's title or H1. -2. **What problem are we solving?** One or two short paragraphs from the customer's point of view, followed by a short bulleted list of the capabilities the feature introduces (each as a bold name plus one sentence in the customer's voice). -3. **What does this open up?** Four to six bullets naming the outcomes the feature enables — customer confidence, data trust, downstream features unblocked, etc. Each bullet leads with a bold phrase and adds one sentence of why it matters. -4. **What will the user experience look like?** One short paragraph framing the experience, followed by a Mermaid `flowchart TD` showing the user-facing decision and its branches. Keep nodes short and customer-readable. It is acceptable to omit if the change truly has no user interface impact, but this will be rare. -5. **How does the data flow today vs. after this change?** Mermaid `flowchart LR` diagrams. **The number of diagrams in each subsection — both "today" and "after this change" — matches the number of meaningfully distinct paths the spec actually describes.

If there is only one current path worth showing (the common case), produce a single "Today" diagram with a one-sentence lead-in above it and no prose block below — the lead-in is enough.

Every "after this change" diagram is followed by a 3 to 5 sentence prose description placed immediately below the diagram, walking the reader through the flow the diagram shows. When there are two or more "after this change" paths, each prose block must additionally name the trigger or condition that sends the customer down this path rather than the others, and the outcome that differs between paths — a stakeholder reading the prose blocks back-to-back should be able to articulate when each path applies.

If the editor reports it could not preserve a fact while satisfying a criterion, keep the fact. ## Step 6: Self-Check Before Presenting -Run three passes before reporting the summary as done. Each pass has a single focus, and **each pass begins with a fresh Read of the output file from disk** — do not check against working memory or the draft you held while writing. The Read tool call is required, not optional. Working memory drifts from what actually landed on disk; only the file contents matter. +Run three passes before reporting the summary as done.

The Read +tool call is required, not optional. Working memory drifts from what actually landed on disk; only the file contents +matter. ### Pass A: Internal-consistency / contradiction check -**First, use the Read tool to load the output file from disk.** Then list every load-bearing claim the document makes — capability included, capability deferred, behavior described in a diagram, prose narrative below a diagram, item under "What is intentionally not in this slice", trade-off or framing call in "What we are asking stakeholders". For every pair of claims, ask: does claim X assert something that claim Y denies or implies the opposite of? Pay special attention to: - -- **Diagram vs. exclusion.** A capability shown in any data-flow diagram (or its prose block below) that "What is intentionally not in this slice" says is deferred, and vice versa. This is the most common form of contradiction: a diagram walks the customer through a step that uses a capability the exclusion section says is not in the slice. The fix is almost always to disambiguate the wording on one side — clarifying that the diagram is showing a narrower capability than the exclusion appears to forbid, or vice versa. -- **UX vs. data flow.** A behavior in the user-experience flowchart that contradicts a behavior in any data-flow diagram, or vice versa. -- **Outcomes vs. exclusion.** A capability named in "What does this open up?" that "What is intentionally not in this slice" says is deferred. -- **Diagram vs. diagram.** An assumption in the prose under one diagram that conflicts with an assumption in the prose under another diagram. -- **Vocabulary collisions.** The same term used to mean two different things in different sections (for example, "share" used both for *sending a URL another user can open* and for *publishing a view to your whole organization*), or different terms used for the same thing in different sections. +**First, use the Read tool to load the output file from disk.** Then list every load-bearing claim the document makes — +capability included, capability deferred, behavior described in a diagram, prose narrative below a diagram, item under +"What is intentionally not in this slice", trade-off or framing call in "What we are asking stakeholders".

For every contradiction found, take an evidence-based approach to resolving it: -1. **Re-read the source specification** identified in Step 1. The spec is the authoritative source for what the feature does and does not do. Most contradictions in the summary are translation errors — the spec is internally consistent and the summary mistranslated one side. -2. **If the spec resolves the contradiction:** edit the summary so both sides match the spec. If the apparent contradiction is actually a terminology collision (the same word covering two distinct concepts), disambiguate the wording — typically by renaming one usage to a more specific term that the source spec, its CLAUDE.md, or its project-discovery vocabulary already supports. Record in working memory which contradiction was resolved and how, so the same disambiguation can be applied uniformly across every section. -3. **If the spec does not resolve the contradiction** — because the spec is silent on the point, the spec itself is internally inconsistent, or the resolution depends on a judgment call only the user can make — **stop and ask the user.** Do not guess. Use `AskUserQuestion` to surface a structured ask containing: - - **A plain-language description of the contradiction**, naming both sides explicitly ("Section X says A; Section Y says B; these conflict because…"). Quote the actual phrasing from each section. - - **Two to four resolution options.** Typical patterns: keep A and rewrite B; keep B and rewrite A; reconcile by disambiguating terminology and using the disambiguated terms in both sections; move the contradicting capability into "What is intentionally not in this slice" and remove it from elsewhere. - - **Your recommended option, marked clearly,** with a one-sentence reason grounded in the source spec, the project's conventions, or the stakeholder framing the user provided in Step 1. The recommendation must be a concrete option from the list above, not a fresh suggestion. - - **A direct request that the user pick which resolution to apply.** - -After applying any contradiction-driven edits, Read the file from disk again before continuing.

Each heading names its content and is not a generic label. 3. Each paragraph carries one idea and leads with it. 4. No sentence runs past the soft length flag (about thirty words) without reason. -5. No blocklisted word is present. The shared writing-voice blocklist ("Avoided words and phrases" and "AI slop to avoid") is authoritative; layered on top of it, this skill's own domain-specific list for a non-technical stakeholder: - - **No engineering artifacts.** No file paths, function names, class names, database tables or columns, API endpoints, HTTP verbs, library or framework names, environment variables, queue or topic names, or language primitives. - - **No engineering hedges.** No "eventually consistent", "idempotent", "race condition", "backfill", "migration", "schema", "payload", "request/response", "stateless", "async", "webhook", "polling vs. push", or similar. If a concept like this is load-bearing, restate it as a user-visible behavior or omit it. - - **No leftover scaffolding.** Template placeholders, TODOs, "TBD", or example text from the template that was not replaced with real content. - - **Closing questions are stakeholder-answerable.** A non-technical reader can give a real answer without asking an engineer what the question means. -6. Every fact is preserved — every capability, exclusion, quantity, named entity, and stated condition or qualifier from the source spec survives with its precision intact. +5.

The +Pass C read-through must run against the post-fix contents, not your memory of what you intended to fix. ### Pass C: Reading-order and progressive-disclosure check -**First, use the Read tool to load the output file from disk again** — even if Pass B required no edits. This re-load is what makes Pass C an actual third pass rather than a continuation of Pass B's attention. Then read the document straight through, top to bottom, as someone arriving cold. Verify the document builds on itself rather than assuming context from a later section: - -- **The opening establishes the customer problem before naming any capability.** A reader should know *who is hurting and why* before they see *what we are building*. -- **Each section uses only vocabulary the reader has already encountered.** A noun that appears in the data-flow diagram should have been introduced in the problem or capabilities sections — not first defined inside the diagram. Acronyms and product-internal names appear only if a stakeholder would already know them; otherwise generalize one level up ("the telematics provider", "the customer list"). -- **Diagrams are readable on their own.** Node labels and edge labels tell the story without requiring the surrounding prose. A reader who only skims the diagrams should still get the shape of the change. -- **Diagram counts match the spec, not the template.** Both "today" and "after this change" subsections have one diagram per meaningfully distinct path in the spec — no padding to two, no collapsing distinct paths into one. A spec with one current path and three new paths should produce 1 today diagram + 3 after-this-change diagrams. A spec with two current paths and one new path should produce 2 today diagrams + 1 after-this-change diagram. -- **Every "after this change" diagram has a 3-5 sentence prose block immediately below it.** The block walks through the flow. When two or more "after this change" paths exist, each block also names what triggers this path and what outcome differs from the others, so a stakeholder reading the blocks back-to-back can articulate when each path applies. When only one "after this change" path exists, the block walks the flow without manufacturing a contrast against absent siblings. -- **The "Today" subsection scales the same way.** A single today diagram needs only its one-sentence lead-in — no prose block below. Two or more today diagrams each get a 3-5 sentence prose block below that walks the flow, names the pain point, and names what makes this current path distinct from the other current paths. -- **The "today vs. after this change" pairing is obvious.** The before-and-after diagrams sit close enough together that the contrast is visible without scrolling back and forth. -- **The "intentionally not in this slice" list comes after the reader understands what *is* in the slice.** Out-of-scope only makes sense once in-scope is concrete. -- **The closing questions follow from the body.** Each question should connect to a specific section above it — not introduce a new topic the document never mentioned. -- **No question in "What we are asking" restates an item from "What is intentionally not in this slice".** For each closing question, find the exclusion item it would map to. If the question is essentially *"is this exclusion OK?"* with no new trade-off or alternative attached, remove it — the closing one-liner at the bottom of "What is intentionally not in this slice" already collects that confirmation. Every remaining question in "What we are asking" must present a named alternative, an unresolved framing call, or an open question the spec itself names. - -If any check in any pass fails, fix it with Edit and Read the file again before re-running the affected pass. If a Pass A edit changes content that Pass B or Pass C already cleared, re-run those passes against the new content — contradiction fixes can re-introduce language or reading-order issues that the earlier passes caught.

Acronyms + and product-internal names appear only if a stakeholder would already know them; otherwise generalize one level up + ("the telematics provider", "the customer list"). +- **Diagrams are readable on their own.** Node labels and edge labels tell the story without requiring the surrounding + prose. A reader who only skims the diagrams should still get the shape of the change. +- **Diagram counts match the spec, not the template.** Both "today" and "after this change" subsections have one diagram + per meaningfully distinct path in the spec — no padding to two, no collapsing distinct paths into one. A spec with one + current path and three new paths should produce 1 today diagram + 3 after-this-change diagrams. A spec with two + current paths and one new path should produce 2 today diagrams + 1 after-this-change diagram. +- **Every "after this change" diagram has a 3-5 sentence prose block immediately below it.** The block walks through the + flow. When two or more "after this change" paths exist, each block also names what triggers this path and what outcome + differs from the others, so a stakeholder reading the blocks back-to-back can articulate when each path applies. When + only one "after this change" path exists, the block walks the flow without manufacturing a contrast against absent + siblings. +- **The "Today" subsection scales the same way.** A single today diagram needs only its one-sentence lead-in — no prose + block below. Two or more today diagrams each get a 3-5 sentence prose block below that walks the flow, names the pain + point, and names what makes this current path distinct from the other current paths. +- **The "today vs. after this change" pairing is obvious.** The before-and-after diagrams sit close enough together that + the contrast is visible without scrolling back and forth. +- **The "intentionally not in this slice" list comes after the reader understands what _is_ in the slice.** Out-of-scope + only makes sense once in-scope is concrete. +- **The closing questions follow from the body.** Each question should connect to a specific section above it — not + introduce a new topic the document never mentioned. +- **No question in "What we are asking" restates an item from "What is intentionally not in this slice".** For each + closing question, find the exclusion item it would map to. If the question is essentially _"is this exclusion OK?"_ + with no new trade-off or alternative attached, remove it — the closing one-liner at the bottom of "What is + intentionally not in this slice" already collects that confirmation. Every remaining question in "What we are asking" + must present a named alternative, an unresolved framing call, or an open question the spec itself names. + +If any check in any pass fails, fix it with Edit and Read the file again before re-running the affected pass. If a Pass +A edit changes content that Pass B or Pass C already cleared, re-run those passes against the new content — +contradiction fixes can re-introduce language or reading-order issues that the earlier passes caught.
