The failure modes are identical regardless of stack: + +**Claude fabricates codebase facts.** I asked about a dependency. Claude confidently told me it was a local path dependency. I checked the package manifest — it was installed from a registry. Claude never read the file. It guessed, and it guessed wrong. → **READ forces the agent to look at the code before talking about it.** + +**Claude can't tell questions from instructions.** I asked "did you also improve the Claude Code setup in this project?" Claude answered "No" — then a validation hook rejected the response for "asking permission instead of implementing." Nobody asked it to implement anything. → **CLASSIFY makes the agent declare its mode before acting. Questions get answers, not implementations.** + +**Claude declares victory early.** Tests pass, but the old function name still appears in three files because nobody grepped for it after the rename. → **VERIFY runs checks after every meaningful change, and the Definition of Done has six explicit gates — not just "tests green."** + +**Claude drifts between modes silently.** You ask it to explain something. Halfway through, it starts editing files. You ask it to plan. It reads four files, reads four more, reads four more — planning loop, zero output. → **ACT defines what each mode means and requires explicit state transitions.** + +None of these are model failures. They're workflow failures. Claude is capable of doing all of this correctly — it just needs structure that makes the right behaviour the default behaviour. + +--- + +## The Five-Step Loop + +**READ** forces the agent to look at the code before talking about it. For multi-layer apps, read both sides of a boundary before changing either. For libraries, read tests alongside implementation. Never fabricate — if you haven't read it, say so. + +**CLASSIFY** makes the agent declare what mode it's in (Plan, Implement, Explain, Debug, Review) and what complexity level it's dealing with — before it touches anything. Mode transitions must be explicit: "Switching to Implement mode because the plan is approved." Silent drift is the #1 source of planning loops and premature fixes. + +**ACT** defines what each mode actually means. Implement = write code within 2-3 turns. Explain = no code changes unless asked. Debug = diagnosis with file:line evidence first, fixes only after human reviews findings. If you catch the agent reading a 4th file without writing anything in Implement mode, something's wrong. + +**VERIFY** runs tests after every meaningful change, not just at the end. Two-level stop-the-line escalation: isolated failures get noted and continued past; cross-boundary or security failures get a full stop with diagnosis. Two corrections on the same approach = cut your losses and rewind. + +**LOG** captures what went wrong in two complementary files: `docs/lessons.md` for behavioural mistakes ("assumed API contract without reading frontend") and `docs/footguns.md` for architectural landmines ("auth nonce spans 4 components; breaking any one silently breaks login"). These are loaded contextually, not every session. + +The footguns file seeds itself during setup. The implementation prompt tells Claude Code to read the actual codebase and find real cross-domain coupling — not invent hypothetical ones. On the PHP library, it found six: normalization pipeline order dependencies, binary dictionary cache version coupling, regex error suppression in the XSS scorer, and three more — all with file:line evidence. On the medical scribe, it found eight — despite the project being at milestone 1. Multi-stack projects create coupling early; most of the scribe's footguns came from unvalidated cross-layer contracts and in-memory state management, not feature complexity. These aren't boilerplate warnings. They're the sharp edges a new contributor would hit on day two. + +The footguns file also feeds a second mechanism: **local CLAUDE.md files.** A file at `src/auth/CLAUDE.md` is automatically loaded whenever Claude works in that directory — no explicit loading required. When a footgun maps to a specific directory, a one-line summary is propagated to that directory's local CLAUDE.md. Put the guardrail where the danger is, not in a file the agent might skip. + +One limitation: not every footgun maps cleanly to a directory. The medical scribe had a WebSocket URL mismatch spanning `.env`, `docker-compose.yml`, and a Twig template — three root-level files across three layers. No single subdirectory qualifies for a local CLAUDE.md. Some footguns are cross-cutting configuration, not module-specific. The central footguns.md catches these; the propagation rule doesn't. + +--- + +## Where It Lives + +The loop sits in a layered system where only the first layer loads every session: + +``` +Layer 1 — Runtime (CLAUDE.md, ~100-120 lines) ← loads every session +Layer 2 — Local Context (directory-level CLAUDE.md) ← auto-loads per directory +Layer 3 — Skills (3-5 focused slash commands) ← loads on demand +Layer 4 — Playbooks (planning workflows) ← loads on demand +Layer 5 — Evaluation (agent evals, CI validation) ← loads on demand +``` + +100-120 lines. That's the entire always-loaded instruction set. Everything else loads when needed. This matters because auto-generated context files reduce success rates by ~3% while increasing inference cost by over 20%. The system prompt consumes ~50 of the model's ~150-200 instruction budget — so CLAUDE.md gets roughly 100-150 effective instructions. Spend them wisely. + +### The Guidelines Split + +Most projects accumulate two instruction files: a project-specific CLAUDE.md and a shared coding standards file (often `.github/instructions/ai-agent-guidelines.instructions.md`). These MUST NOT overlap. I learned this the hard way — my Tauri app had a Definition of Done in CLAUDE.md _and_ in the guidelines file, with subtly different gates. The agent followed whichever it read last. + +The clean split: **CLAUDE.md owns workflow** (the execution loop, autonomy tiers, DoD, log files, router table). **The guidelines file owns engineering practices** (coding patterns, communication style, testing strategy, error handling templates). If a rule would be identical across every project, it belongs in guidelines. If it changes per project, it belongs in CLAUDE.md. + +``` +❌ Overlap — agent follows whichever it reads last: + CLAUDE.md DoD: "tests green, preflight passes, logs updated" + Guidelines DoD: "tests pass, rollback strategy exists, verification story" + +✅ Clean split: + CLAUDE.md DoD: 6 project-specific gates (tests, preflight, Ask First, logs, notes, grep) + Guidelines: testing *strategy* (unit for logic, integration for boundaries) — not DoD gates +``` + +The reduction varies by how much overlap existed. The PHP library's guidelines went from 47 to 39 lines — a modest 17% trim where only the DoD section overlapped. The medical scribe's guidelines went from 95 to 51 lines — a 46% reduction — because the file had a full architecture section, a 7-point cross-layer checklist, stop-the-line rules, and core workflow rules that all belonged in CLAUDE.md. The bigger your existing guidelines file, the more overlap you'll find. + +### Conditional Loading + +Claude Code supports `.github/instructions/` files with `applyTo` frontmatter that controls when they load. A file with `applyTo: "**/*.ts"` only loads when Claude touches TypeScript files. Rust conventions only load for `.rs` files. In practice this means a multi-stack project doesn't burn instruction budget on irrelevant language rules: + +```yaml +# .github/instructions/rust.instructions.md +--- +applyTo: "**/*.rs" +--- +# Rust conventions for this project +- Use parking_lot for mutexes, tokio for async +- Never .unwrap() in Tauri commands — propagate errors with context +``` + +That file is invisible when you're working on TypeScript. Free context savings. + +--- + +## The Hook Saga (or: How I Wasted a Day on Prompt Engineering) + +The most interesting failure in this system was the anti-rationalisation hook. The idea was simple: after every Claude response, send it to Haiku for independent assessment. Does the response actually complete the work, or is it rationalising — calling things "pre-existing," deferring to follow-ups nobody asked for, listing problems without fixing them? + +Six versions. One day. + +| Version | What I Tried | What Broke | +| ------- | --------------------------------- | -------------------------------------------------------------- | +| v0.1 | Single paragraph, no intent check | False positives on every question | +| v0.2 | Hook infrastructure | Exit codes, infinite loop guard — no prompt iteration | +| v0.3 | Keyword matching for user intent | Haiku can't see the user message — it only gets the response | +| v0.4 | Response-pattern detection | Haiku returned prose instead of JSON | +| v0.5 | Two-step flow with JSON preamble | Claude's own "Want me to fix?" offer triggered false match | +| v0.6 | Pasted content detection | Best version, but JSON schema fragile across reimplementations | + +The fundamental problem: **prompt-type Stop hooks only see the assistant's response.** They can't read the conversation. They can't see what the user asked. Intent detection is always inferred, never observed. + +The moment that killed it: I asked "did you also improve the Claude Code setup in this project?" Claude correctly answered "No — want me to?" The hook rejected this as "asking permission instead of implementing." The terminal showed the same wrong rejection three times — once as the hook output, once as a framework echo, once in the summary wrapper. One false positive, displayed as emphatic consensus. + +The conclusion: **deterministic command hooks for mechanical enforcement, CLAUDE.md rules for behavioural guidance.** A `deny-dangerous.sh` PreToolUse hook that blocks `rm -rf`, force pushes, and pipe-to-shell patterns works 100% of the time. A prompt hook trying to judge whether work is complete works maybe 70% of the time — and the 30% failure rate erodes trust faster than the 70% success rate builds it. + +This is worth knowing because if you're building agent workflows, you will be tempted to build this exact hook. Save yourself the day. + +--- + +## What You Get + +The system breaks down into three adoption tiers: + +| Tier | What | When | +| ------------ | -------------------------------------------------------- | ---------------------------------------- | +| **Minimal** | CLAUDE.md + deny-dangerous hook | Getting started, solo project | +| **Standard** | + 3-5 skills + stop/format hooks + local CLAUDE.md files | Active development, team project | +| **Full** | + agent evals + CI validation + permission profiles + ADRs | Long-lived project with incident history | + +The key pieces: + +**Autonomy tiers** — not everything needs permission, not everything is free. Tests and linting? Always run. Public API changes, database migrations, dependency additions? Stop and ask first, with a micro-checklist (which boundary, did you read the related code, what's the rollback command). Delete test files to make builds pass? Never. + +Note: the autonomy tiers in CLAUDE.md are behavioural guidance. The actual tool-level permissions live in `.claude/settings.local.json` — you'll build this allowlist over time as you approve commands repeatedly. Start empty, grow organically. + +**Definition of Done** — six explicit gates. Tests green, preflight passes, no unapproved boundary changes, logs updated if you tripped, working notes current, old patterns grepped after renames. The agent can't say "task complete" until all six are true. + +**Stack-adaptive hooks** — define your stack once, hooks adapt. The build verification hook checks `git diff` for modified file types and only runs relevant checks. A Rust change runs `cargo fmt --check`. A PHP change runs `php -l`. A TypeScript change runs `tsc --noEmit`. No changes, no checks. + +**Project-specific deny rules** — beyond the universal blocks (rm -rf, force push), add blocks for files that must be modified through tooling. A PHP library with binary-encoded dictionaries? Block direct edits to `.bin` files — the encoder script is the only safe path. Generated code? Block direct edits — the generator is the source of truth. GPU model files too large for direct edit? Block `.nemo` files. Infrastructure changes without a plan? Block `terraform apply` without a preceding `terraform plan`. The categories expand with the project. + +--- + +## Adapting to Your Project + +The system adapts to project shape. I've run it on three projects: a multi-stack Tauri desktop app (TypeScript + Rust), a zero-dependency PHP library, and a four-layer medical scribe (PHP + Python + NeMo GPU + Mercure + Terraform). Same plan, same prompts, different outputs. + +The adaptation is real, not cosmetic. The PHP library's Ask First boundaries name specific classes (`SusFormDetector`, `SusAssessment`, `SusFactor`), specific data files (`profanity_words.bin`, `safe_names.json`), and the binary encoding pipeline. The Tauri app's boundaries name auth, routing, deployment, and cross-layer changes. The medical scribe's boundaries name eight items including PHP↔Python API contracts, the NeMo GPU singleton, Mercure topics, and Strands agent model provider switching. The structure is identical; every detail is project-specific. + +The deny-dangerous hook adapts too. All three projects block the universal patterns (rm -rf, force push, pipe-to-shell). The PHP library adds blocks for binary dictionary files. The Tauri app adds blocks for .env modifications. The medical scribe adds blocks for `.nemo` model files and `terraform apply` without a plan — a different category of project-specific protection than the other two. + +Getting CLAUDE.md under the line target depends on the starting point. The PHP library (Prompt A — new file) took 127 lines on first pass and required two compression passes. The medical scribe (Prompt B — existing CLAUDE.md migration) landed at 114 lines on first pass, well under the 120 target. The difference: Prompt B migrates domain content to `docs/domain-reference.md` first, which clears the canvas. The entire line budget goes to the execution loop instead of fighting existing content for space. If your project has a content-heavy CLAUDE.md, Prompt B may be the easier path. + +| Aspect | App (Tauri) | Library (PHP) | App (Medical Scribe) | +| ----------------------- | --------------------------------------------- | ------------------------------------------- | ----------------------------------------------------------------- | +| CLAUDE.md | 121 lines | 99 lines | 118 lines | +| Skills | 6 (core + /research, /code-review, /review) | 3 (core only) | 5 (2 updated, 3 new) | +| Footguns seeded | 14 | 6 | 8 | +| Agent evals | 5 (from real incidents) | 5 (from git history) | 5 (3 real incidents, 2 common modes) | +| Ask First boundaries | Auth, routing, deployment, API contracts, DB | Public API, dependencies, data/config files | 8 (PHP↔Python contracts, NeMo, Mercure, Docker, env, Terraform) | +| Local CLAUDE.md files | Planned (14 footguns suggest qualifying dirs) | None needed (flat structure) | 2 (strands_agents/, infra/) | +| Permission profiles | 3 (frontend/backend/infra) | None (single language) | 3 (php-backend/python-agent/infrastructure) | +| Guidelines file | 258 lines (ownership split pending) | 47 → 39 lines (17% reduction) | 95 → 51 lines (46% reduction) | +| Prompt path | N/A (pre-dates prompts) | A (new file) | B (existing migration) | +| Original CLAUDE.md | N/A | N/A | 145 lines → 85 lines in domain-reference.md | +| Compression struggle | Yes | Yes (127 → 99) | No (114 first pass) | +| Implementation sessions | Built over weeks | 2 sessions (generate + fix) | 1 session (all phases) | + +For libraries, skip `/research` (the default READ step handles single-domain codebases) and `/code-review` (the default Review mode is sufficient). Don't create skills that won't earn their place — the skill justification test in the plan requires each skill to have a distinct artefact, a hard workflow gate, a special failure mode, or a repeatable structured output. + +The medical scribe revealed a gap in the prompts: it already had three skills and two hooks before implementation. Phase 1b was update-and-extend rather than create-from-scratch. Phase 1c replaced inline hook commands with external scripts. Prompt B handles CLAUDE.md migration, but the prompts don't explicitly address pre-existing skills and hooks. If your project has partial tooling already, expect Phase 1b/1c to adapt rather than create. + +Another finding from the scribe: even at milestone 1 with only 11 commits, three of five agent evals came from real git history — an EventSource ordering bug, a Docker volume mount mismatch, and an audio format assumption. The plan expected new projects to lean on common failure modes for seeding evals. Multi-stack projects generate qualifying incidents early because the cross-layer boundaries create failure opportunities before the features do. + +--- + +## How to Set It Up + +Two files do all the work. Give them to Claude Code and it builds the system for your project. + +### Step 1: Audit your existing files + +If you have an `ai-agent-guidelines.instructions.md` or similar shared standards file, remove any execution loop, DoD, stop-the-line, or working memory content. Those now live in CLAUDE.md. Keep engineering practices, communication style, and templates. + +### Step 2: Add the plan files + +Copy these two files into your project: + +- `ai-workflow-improvement-plan-prime.md` — the full system design +- `ai-workflow-implement-prompts-prime.md` — the implementation prompts + +Both files are available in the [ai-planning-playbook](https://github.com/blundergoat/ai-planning-playbook) repo. + +### Step 3: Choose your starting point + +**New project (no existing CLAUDE.md):** Open the implementation prompts file. Copy the Phase 0 prompt. Edit the stack definition. Run it. You'll get a CLAUDE.md, a deny-dangerous hook, and a settings.json — the Minimal tier. + +**Existing project:** Skip Phase 0. The prompts have two variants for Phase 1a — one for new files, one that migrates existing CLAUDE.md domain content to a reference doc before building the workflow system on top. Note: the migration may be incomplete on the first pass. On the PHP library, Code Style and PHP Requirements sections were silently dropped because they partially overlapped with content in the guidelines file. Audit the migration output against the original before continuing. + +### Step 4: Iterate + +Run Phase 1a, 1b, 1c in order. Each creates a focused set of files. Don't run them all at once — the whole point of splitting them was to stay within the instruction budget. Budget a second pass after Phase 1a to verify nothing was dropped during compression — though Prompt B projects may not need it if the domain content migration frees up enough budget. + +Run Phase 2 for the Full tier: agent eval regression tests, RFC 2119 priority markers, CI validation. You can run it immediately after Phase 1 — the medical scribe ran all phases in a single session — though waiting gives you more real incidents to seed evals from. On the PHP library, Phase 2 found five agent evals from real git history — safe-name false positives, evasion patterns, threshold calibration drift. Even a library with no "production incidents" has a git history worth mining. + +--- + +## What's Deliberately Left Out + +**Prompt hooks for semantic judgement.** I tried. Six versions. It doesn't work. See the hook saga above. + +**Rigid enforcement of every rule.** The plan uses RFC 2119 language (MUST/SHOULD/MAY) to make priority visible. The execution loop, autonomy tiers, and definition of done are MUST. Log hygiene is SHOULD. The structural debt trigger is MAY. Not everything is equally important. + +**Global git config changes.** The plan recommends gitleaks for pre-commit secret scanning, but installing it requires `git config --global core.hooksPath` which affects every repo on your machine. That's a manual step documented in a setup guide, not something an AI agent should do. + +**My project's specific examples.** The plan's examples are illustrative. Replace them with incidents from your own codebase. The principles are universal; the examples are mine. + +--- + +## The Quarterly Shrink + +The system is designed to get smaller over time, not larger. The plan includes a quarterly audit: re-count CLAUDE.md lines, check for stale rules, ask "if I removed this, would the model still do the right thing?" Rules that once helped become constraints as models improve. + +The learning loop files (lessons.md, footguns.md) have their own hygiene: max 15 active lessons, pattern promotion when 3+ share a theme, entries archived after 30 days untriggered. The goal is a system that teaches itself out of needing individual entries. + +--- + +## TL;DR + +Build a five-step loop, enforce it with deterministic hooks, keep it under 120 lines. + +--- + +_Written with AI-assisted cognitive framework ([GOAT System](https://blundergoat.com)).

Same codebase, same execution loop concept, different agent mechanics. The comparison is direct. + +### What Maps Cleanly + +The core system transfers without modification: the five-step loop, autonomy tiers, Definition of Done, footguns file, lessons file, router table, essential commands, and the eval concept. These aren't Claude Code features — they're workflow patterns that work on any agent that reads a root instruction file. + +Both agents produced similar footgun counts from the same codebase (8 from Claude Code, 7 from Codex) with overlapping findings: the Mercure silent publish failure, the three independent session state buckets, the NeMo GPU singleton, the DynamoDB provisioned-but-unused gap. The convergence suggests the footgun-seeding approach works regardless of which agent does the reading. + +### What Had No Equivalent + +| Claude Code feature | Codex replacement | Trade-off | +|---|---|---| +| PreToolUse hooks (deny-dangerous) | `scripts/deny-dangerous.sh` as policy documentation | Claude Code blocks `rm -rf` before it executes. Codex documents the policy for review and CI but cannot prevent the command from running. | +| Stop hooks (lint after every turn) | Preflight script, run manually or in CI | Claude Code catches formatting issues continuously. Codex catches them at checkpoints. | +| PostToolUse hooks (auto-format) | Nothing — manual or preflight | No auto-formatting on edit. | +| Local CLAUDE.md (directory auto-load) | Centralised footguns.md + router references | Claude Code loads warnings automatically when entering a directory. Codex requires the agent to check the router table. | +| Slash commands (/preflight, /debug) | Playbook files in `docs/codex-playbooks/` | Same content, different loading mechanism. | +| Permission profiles (.claude/profiles/) | Behavioural guidance in AGENTS.md only | No tool-level scoping. | +| /compact, /insights | No equivalent | Codex context is per-task, not per-session. No session management needed — but no session learning either. | + +The hooks gap is the fundamental difference. Claude Code has three layers of enforcement: behavioural guidance in CLAUDE.md, deterministic hooks that block commands before execution, and stop hooks that run checks after every turn. Codex has one layer: behavioural guidance in AGENTS.md. The deny-dangerous script exists, but it's a policy document — inspectable, auditable, referenced from preflight and CI — not a runtime interceptor. + +### What's Better Without Hooks + +No hooks isn't purely a loss. Five things work better in the Codex version: + +**No false positives.** The hook saga documented six versions of a prompt-based stop hook, all of which produced false positives that eroded trust. Codex sidesteps this entirely — there's no mechanism to produce false positives because there's no semantic enforcement mechanism. + +**Inspectable policy.** `deny-dangerous.sh` is a plain shell script committed to the repo. Anyone can read it, diff it, argue about it. Claude Code's deny hook is the same, but the stop and format hooks involve JSON configuration in `.claude/settings.json` that's less transparent. + +**Reused existing infrastructure.** Codex extended the project's existing `preflight-checks.sh` rather than creating parallel hook machinery. The deny policy became step 3 of the existing preflight script. Claude Code's hooks exist alongside preflight, creating two enforcement paths. + +**Deterministic validation.** `scripts/context-validate.sh` checks that AGENTS.md references exist, playbooks have required sections, and footguns have evidence. Claude Code's CI workflow does similar checks, but Codex's version is a local script you can run anytime — no CI pipeline required. + +**Committed overlap report.** When Codex applied the guidelines ownership split, it created a persistent `guidelines-ownership-split.md` documenting what was removed and why. Claude Code's split happens in a chat session and the reasoning evaporates when the session ends. + +### What's Worse Without Hooks + +The enforcement gap is real and shows up in six places: + +**No runtime blocking.** If Codex decides to run `rm -rf /`, nothing stops it. AGENTS.md says "Never do this." The deny-dangerous script documents the policy. But neither intercepts the command. Claude Code's PreToolUse hook blocks it before execution — 100% of the time, mechanically, regardless of whether the agent read the rules. + +**No automatic stop-the-line.** Claude Code's stop hook runs `php -l` or `cargo fmt --check` after every turn. If there's a syntax error, the agent sees it immediately. Codex only catches these at preflight checkpoints — meaning errors can accumulate between checks. + +**Ask First is behavioural only.** In Claude Code, the Ask First micro-checklist is reinforced by the stop-the-line hook — if a cross-boundary change breaks something, the hook catches it. In Codex, Ask First relies entirely on the agent choosing to follow the rule. + +**No directory-level warnings.** Claude Code auto-loads a local CLAUDE.md when entering `strands_agents/` or `infra/`. Codex has no confirmed equivalent — the footguns are centralised, not positioned where the danger is. + +**No permission lanes.** Claude Code's permission profiles restrict which files a frontend session can edit. Codex has no tool-level scoping — every session has access to everything. + +**No session compaction.** Claude Code's `/compact` and context management tools help with long sessions. Codex's per-task context model avoids this problem differently — each task starts fresh — but loses continuity between tasks. + +### The Honest Summary + +The system's core — the execution loop, autonomy tiers, definition of done, learning loop — is agent-agnostic. It works on both. The enforcement layer is where they diverge. Claude Code enforces mechanically (hooks block commands, format files, check syntax). Codex enforces culturally (AGENTS.md rules, policy scripts, preflight checks, CI). + +For solo developers who trust their agent and verify with preflight, the Codex model is sufficient. For teams, long-lived projects, or codebases where a single bad command has high blast radius, Claude Code's hooks provide a safety net that behavioural guidance alone can't match. + +The workflow system is portable.

Projects accumulate rules, playbooks, skills, and docs — if everything loads at once, the model gets worse at following _all_ of it. + +**Key evidence:** + +- Auto-generated context files reduce success rates by ~3% while increasing inference cost by 20%+ (HumanLayer) +- Frontier models follow ~150-200 instructions reliably; Claude Code's system prompt consumes ~50, leaving ~100-150 for CLAUDE.md (Philipp Schmid, HumanLayer) +- Tools mentioned in AGENTS.md are used 160x more often than unmentioned ones — the router table is the highest-signal section (GitHub 2,500-repo) + +**Design decision:** Only Layer 1 (CLAUDE.md, ~100-120 lines) loads every session. Everything else loads on demand via the router table, slash commands, or automatic directory-level loading. This keeps the always-loaded budget small while making everything else discoverable. + +**Why 5 layers, not 3 or 7:** Each layer has a distinct loading trigger — always (L1), automatic per-directory (L2), on-demand by user (L3/L4), or CI/regression (L5). Fewer layers would combine different loading semantics. More would create layers with no meaningful distinction. + +--- + +## Guidelines Ownership Split + +**Problem it solves:** Projects with both CLAUDE.md and a shared guidelines file (e.g., `ai-agent-guidelines.instructions.md`) end up with overlapping rules — two different Definitions of Done, two different testing strategies. The agent follows whichever it reads last, creating inconsistent behaviour. + +**Source:** Direct experience on a Tauri app where CLAUDE.md had a DoD ("tests green, preflight passes, logs updated") and the guidelines file had a different DoD ("tests pass, rollback strategy exists, verification story"). The agent alternated between them unpredictably. + +**Design decision:** Clean ownership boundary. CLAUDE.md owns workflow (execution loop, autonomy tiers, DoD, logs, router). Guidelines owns engineering practices (coding patterns, communication style, testing strategy, error handling). Test: if a rule would be identical across every project, it belongs in guidelines. If it changes per project, it belongs in CLAUDE.md. + +**Evidence it works:** Applying the split to a PHP library shrunk the guidelines file from 47 to 39 lines — the DoD section ("Before Marking Done") was the overlap. What survived was the right shape for a shared file. + +--- + +## Layer 2: Local CLAUDE.md Files + +**Problem it solves:** `docs/footguns.md` is a central index the agent must explicitly load. If it doesn't load the file, it doesn't see the warnings. A local CLAUDE.md at `src/auth/CLAUDE.md` is read automatically whenever Claude works in that directory — no explicit loading required. + +**Source:** Claude Code's automatic CLAUDE.md loading behaviour (reads CLAUDE.md in the working directory plus all ancestor directories up to the project root). + +**Design decision:** Footgun entries that map to a specific directory are propagated (not moved) as one-line summaries to that directory's local CLAUDE.md. The central footguns.md remains the source of truth; local files are read-time copies for automatic loading. Put the guardrail where the danger is, not in a file the agent might skip. + +**Guard against over-creation:** Only create local files when a directory has 2+ footgun entries, is an Ask First boundary, or has conventions differing from the project default. Most directories don't qualify. A flat-structure library rarely needs any. + +--- + +## Project Shape: App vs Library + +**Problem it solves:** A one-size-fits-all plan wastes instruction budget on irrelevant content. A PHP library doesn't need `/research` (single-domain, the READ step suffices), permission profiles (single language), or `confusion-log.md` (single-domain confusion is rare). An app with 14 footguns across TypeScript and Rust needs all of these. + +**Source:** Cross-referencing two real implementations — a Tauri app (121-line CLAUDE.md, 6 skills, 14 footguns) and a PHP library (99-line CLAUDE.md, 3 skills, 6 footguns). Same plan, same prompts, meaningfully different outputs. (BlunderGOAT Scanner, BlunderGOAT CC) + +**Design decision:** Every section in the plan that differs by project shape includes explicit app vs library guidance. The adaptation table in the plan makes this visible in one place. + +--- + +## Skill Justification Test + +**Problem it solves:** Skill proliferation. Early versions of the plan had 8+ skills. Each skill consumes instruction budget when loaded and creates maintenance burden. Most didn't earn their place — they were templates, not workflows. + +**Source:** Direct experience. Four skills were downgraded during the v0.8 revision after failing the justification test. + +**Design decision:** A skill must have at least one of: a distinct artefact, a hard workflow gate, a special failure mode, or a repeatable structured output. The plan documents which skills passed and which were downgraded to sections within other files. This prevents future skill sprawl. + +| Former Skill | Why it failed | Where it went | +| ------------------- | ------------------------------------------------------ | ----------------------------------- | +| `/annotation-cycle` | No distinct artefact — it's a planning refinement step | Section in mob elaboration playbook | +| `/sbao-synthesis` | Template, not a workflow with gates | Section in SBAO planning playbook | +| `/review-triage` | Normal review behaviour, not a distinct mode | Review branch of the ACT step | +| `/revert-rescope` | Tactic (2 sentences), not a workflow | Paragraph in VERIFY/stop-the-line | + +--- + +## Instruction Budget Constraint + +**Problem it solves:** More instructions doesn't mean better compliance. It means worse compliance across the board. Degradation is uniform, not sequential — the model doesn't just ignore rules at the bottom; it gets worse at following all of them equally. + +**Sources:** HumanLayer (auto-generated context data), Philipp Schmid (instruction following limits), GitHub 2,500-repo analysis (tool mention uplift) + +**Design decision:** Hard line target (100 for libraries, 120 for apps, never over 150). Cut priority list for when you go over. "Never cut" list for the three things that matter most: execution loop, autonomy tiers, definition of done. Code examples beat prose — one snippet communicates more per token than three paragraphs. + +**Why these specific targets:** The PHP library's first pass produced 127 lines (27 over the 100-line target). Compression got it to 99. The Tauri app stabilised at 121. Both are well under the 150 hard ceiling, leaving headroom for the system prompt's ~50 instruction overhead. + +--- + +## Section 1.1: Default Execution Loop + +Each step exists because a specific failure mode is common enough to warrant structural prevention. + +### READ + +**Problem:** Claude fabricates codebase facts. It guesses file contents, dependency versions, API contracts, and configuration values without reading the actual files. The guesses are confident and often plausible, making them hard to catch. + +**Source:** Direct experience — asked about a dependency, Claude said it was a local path dependency, it was actually installed from a package registry. It never read the manifest. (BlunderGOAT CC) + +**Design decision:** READ is the first step, not optional. For multi-layer apps, read both sides of a boundary before changing either. For libraries, read tests alongside implementation. The "never fabricate" rule is reinforced with a concrete example showing what fabrication looks like vs what reading-first looks like. + +### CLASSIFY + +**Problem:** Two distinct failures. (1) Claude can't distinguish questions from directives — "did you also improve X?" gets treated as "improve X." (2) Claude drifts between modes silently — you ask it to explain something, halfway through it starts editing files. + +**Source:** The question/directive confusion was exposed by the anti-rationalisation hook (see Appendix A in the plan). A correct "No — want me to?" answer was rejected as "asking permission instead of implementing." The mode drift was observed repeatedly across both app and library work. (BlunderGOAT CC, Oruç) + +**Design decision:** CLASSIFY forces two declarations before any action: complexity level (Hotfix / Standard / System / Infra) and mode (Plan / Implement / Explain / Debug / Review). Mode transitions must be explicit. The question vs directive disambiguation rule exists specifically because this confusion was the trigger for a full day of wasted hook engineering. + +### ACT + +**Problem:** Planning loops and premature fixes. In Plan mode, Claude reads file after file without producing an artefact. In Debug mode, Claude starts fixing before understanding the bug. In Explain mode, Claude edits code nobody asked it to edit. + +**Source:** Direct observation across multiple sessions. The "4th file read without writing = stop exploring" heuristic was calibrated from repeated planning loops where Claude read 8-12 files, produced nothing, and ran out of context. (Oruç, Microsoft AutoDev) + +**Design decision:** Each mode has explicit behaviour constraints in a table. State declaration is mandatory ("State: [MODE] | Goal: [one line] | Exit: [condition]"). Switching modes requires an explicit statement with a reason. The anti-BDUF guard prevents premature abstraction (creating interfaces with one implementation, building configurability nobody asked for). + +### VERIFY + +**Problem:** Claude declares victory early. Tests pass, but the old function name still appears in three files because nobody grepped after the rename. Or tests pass but behaviour subtly shifted in a way the tests don't cover. + +**Source:** Direct experience — post-rename grep finding stale references was the specific incident that led to DoD gate #6. The stop-the-line escalation levels come from incident response patterns. (awslabs/aidlc, Microsoft AutoDev) + +**Design decision:** Tests after every meaningful change, not just at the end. Two-level escalation: Level 1 (isolated, note and continue) vs Level 2 (cross-boundary or security, full stop). The "two corrections on same issue = cut losses" rule prevents infinite fix loops — if the approach keeps changing direction, rewind rather than iterate. + +### LOG + +**Problem:** The agent repeats the same mistakes across sessions. Without a learning loop, every conversation starts from zero — same fabrications, same mode drift, same early victory declarations. + +**Source:** Direct experience building two projects over weeks. The same lesson was learned 3-4 times before being written down. The two-file split (lessons.md for agent behaviour, footguns.md for architectural landmines) emerged because they serve different purposes and load at different times. (BlunderGOAT CC) + +**Design decision:** Two complementary files with distinct scopes. lessons.md captures agent behavioural mistakes. footguns.md captures cross-domain architectural traps. confusion-log.md (apps only) captures structural navigation difficulty. Context-based loading rules prevent wasting budget on irrelevant log content. Max 15 active lessons with pattern promotion prevents unbounded growth. + +--- + +## Section 1.2: Autonomy Tiers + +**Problem it solves:** All-or-nothing permission models. Either the agent can do everything (dangerous) or must ask for everything (slow). Most actions are safe and reversible; a few are dangerous and irreversible. The tiers match the permission level to the risk. + +**Source:** Trail of Bits claude-code-config (deny patterns for dangerous commands), awslabs/aidlc (structured agent lifecycle with approval gates) + +**Design decision:** Three tiers — Always (tests, lint, read, write within scope), Ask First (boundary-crossing changes with micro-checklist), Never (delete tests, modify secrets, push main). The micro-checklist for Ask First items forces the agent to prove it has read the related code, checked for footguns, and knows the rollback command before proceeding. + +**Why a micro-checklist, not just "ask first":** Asking "can I change the auth middleware?" without context forces the human to investigate. The checklist front-loads the investigation to the agent, making the human's approval decision informed rather than a rubber stamp. + +--- + +## Section 1.3: Definition of Done + +**Problem it solves:** "Done" means different things in different contexts. Without explicit gates, the agent says "task complete" after tests pass — even if old patterns remain after a rename, logs weren't updated, or a boundary was crossed without approval. + +**Source:** Repeated incidents where "tests green" was treated as done. The six gates were accumulated from real failures: gate #6 (grep after rename) came from a specific incident where three files still referenced an old function name. (BlunderGOAT CC) + +**Design decision:** Six gates, all must be true. No shortcuts. The agent cannot say "task complete" until it can confirm all six. This is a MUST-level rule that is never cut during compression. + +--- + +## Section 1.4: Working Memory and Handoffs + +**Problem it solves:** Context window fills up during multi-turn tasks. The agent loses track of what it's done, what's left, and what decisions were made. When a session ends mid-task, the next session starts from scratch. + +**Source:** Boris Tane's Claude Code workflow (handoff protocols), direct experience with context exhaustion on 10+ turn tasks. + +**Design decision:** Working Notes in tasks/todo.md for 5+ turn tasks. Context escalation ladder (/compact → split → /clear). Handoff template with five sections (Status, Current State, Key Decisions, Known Risks, Next Step). The escalation ladder prevents the common failure of running out of context without a recovery plan. + +--- + +## Phase 1 Skills + +### /preflight + +**Problem:** Shipping broken builds. The agent finishes work and says "done" without running the full check suite. Individual checks (just tests, just lint) miss issues that the full pipeline catches. + +**Design decision:** Mechanical, repeatable structured output with RFC 2119 priorities. MUST items (type-check, lint, compile) cannot be skipped. SHOULD items (full test suite, formatter) can be skipped with reason. The skill produces a structured pass/fail report, not prose. + +### /debug-investigate + +**Problem:** Agents guess fixes before understanding the bug. The instinct is to "just try something" — swap a value, add a null check, toggle a flag. This works ~30% of the time and creates confusing diffs the other 70%. + +**Source:** Microsoft AutoDev paper (diagnosis before intervention), direct experience with premature fix attempts that obscured the root cause. + +**Design decision:** Hard gate — diagnosis with file:line evidence first, fixes only after human reviews findings. The explicit "If you want to 'just try something' before tracing the code path, STOP" instruction exists because this failure mode is nearly universal. + +### /audit + +**Problem:** Fabricated findings. Audits are high-stakes — false positives erode trust, false negatives create risk. LLMs are reliably bad at distinguishing real findings from plausible-sounding ones they invented. + +**Design decision:** Four-pass structure with an explicit fabrication gate at pass 4. Discovery → Verification (re-read each finding) → Prioritisation → Self-Check ("did I fabricate this?"). MUST NOT propose fixes — the audit's job is to find issues, not solve them. + +### /research (apps only) + +**Problem:** Planning without understanding the codebase. The agent proposes an architecture or approach based on assumptions about how the code works, then discovers midway through implementation that the assumptions were wrong. + +**Design decision:** Hard gate — produce research.md with files involved, request flow, boundaries touched, and risks/gotchas (minimum 3 with file:line evidence). No planning until human reviews. Libraries skip this because the READ step is sufficient for single-domain codebases. + +### /code-review (apps only) + +**Problem:** Rubber-stamp reviews. Without structure, the agent says "looks good" or lists trivial style issues while missing architectural concerns. + +**Design decision:** Structured output with RFC 2119 constraints and autonomy tier awareness. The reviewer must identify which boundaries are touched and what the blast radius of the change is. + +--- + +## Phase 1 Hooks + +### deny-dangerous.sh (PreToolUse) + +**Problem:** CLAUDE.md "never" rules work ~70% of the time. A rule saying "never use rm -rf" is behavioural guidance — the model might follow it, might not. A PreToolUse hook that blocks `rm -rf` before it executes works 100% of the time. + +**Source:** Trail of Bits claude-code-config (deny patterns and exit code strategy) + +**Design decision:** Deterministic enforcement at the tool level. Exit 2 with an error message telling Claude what to do instead (not just "blocked"). Project-specific deny rules for files that must be modified through tooling (binary dictionaries, generated code, lock files). + +### stop-lint.sh (Stop hook) + +**Problem:** Formatting and lint issues accumulate during a session. Without continuous checking, the agent produces a batch of violations that are harder to fix after the fact. + +**Source:** Direct experience, BlunderGOAT CC + +**Design decision:** Stack-adaptive — check `git diff` for modified file types, run only relevant checks. MUST exit 0 even on errors (non-zero exit causes infinite fix loops — this was a hard-won lesson). Infinite loop guard. Exclude slow checks (>10s) — those go in /preflight. + +**Why exit 0 on errors:** Stop hooks run after every Claude turn. A non-zero exit tells Claude "something failed, fix it." Claude tries to fix it. The hook runs again. If the fix doesn't clear the error, Claude loops forever. Exit 0 with errors to stderr makes the feedback informational, not imperative. + +### format-file.sh (PostToolUse) + +**Problem:** Manual formatting after every edit is tedious and error-prone. The agent's edits don't match the project's formatting conventions, creating noisy diffs. + +**Design decision:** Automatic formatting on every Edit/Write. Format by file extension using the project's configured formatter. Silence failures — formatting is best-effort, not a gate. + +### Anti-rationalisation hook (removed) + +**Problem it tried to solve:** The agent declaring victory without completing work — calling issues "pre-existing," deferring to follow-ups nobody asked for, listing problems without fixing them. + +**Why it failed:** Prompt-type Stop hooks only see the assistant's response. They cannot read the conversation. Intent detection is always inferred, never observed. Six versions in one day, each failing in a different way. The false positive rate (~30%) eroded trust faster than the success rate (~70%) built it. + +**Source:** Direct experience — one full day of iteration. Documented in Appendix A of the plan and "The Hook Saga" section of the article. + +**Design decision:** Removed entirely. Deterministic command hooks for mechanical enforcement. CLAUDE.md rules for behavioural guidance. Prompt hooks for semantic judgement are structurally unsound with current hook architecture. + +--- + +## Phase 1 Security Hardening + +**Problem it solves:** AI agents can execute arbitrary shell commands. Without deny rules, a hallucinated or misinterpreted instruction could delete files, push to production, or expose secrets. + +**Source:** Trail of Bits claude-code-config (comprehensive deny pattern analysis) + +**Design decision:** Defence in depth. Layer 1: deny-dangerous PreToolUse hook (deterministic blocks). Layer 2: gitleaks pre-commit scanning (manual setup — documented, not executed, because it requires global git config changes). Layer 3: dependency audit in /preflight skill. The manual setup for gitleaks is deliberate — `git config --global core.hooksPath` affects every repo on the machine, which is not something an AI agent should change. + +--- + +## Phase 2: Agent Evals + +**Problem it solves:** CLAUDE.md changes can silently regress agent behaviour. Adding a new rule, removing an old one, or tweaking wording can cause previously-correct behaviour to break. Without regression testing, these regressions are discovered in production work — the worst possible time. + +**Source:** Direct experience — behavioural regressions after CLAUDE.md edits on the Tauri app. A rule change that improved one workflow broke another. (BlunderGOAT CC) + +**Design decision:** An `agent-evals/` directory with flat .md files, each containing a replay prompt from a real incident. When CLAUDE.md or skills change, replay the prompts and verify the agent still handles them correctly. Start with real incidents; for projects with no incident history, seed 1-2 from common stack failure modes and replace with real ones as they occur. + +**Why flat files, not folders:** The initial design used one folder per eval. In practice, each eval is a single .md file with no supporting assets. The folder structure added navigation friction with no benefit. + +--- + +## Phase 2: RFC 2119 Pass + +**Problem it solves:** All rules treated as equally important. The agent can't distinguish between "you MUST run tests" and "you MAY skip the formatter during debugging." Without priority markers, the model allocates equal attention to everything — and when budget is tight, it drops important rules as readily as optional ones. + +**Source:** RFC 2119 (standard for priority language in technical specifications), applied to AI agent instructions. + +**Design decision:** MUST for the execution loop, autonomy tiers, and definition of done. SHOULD for log hygiene, working memory, session handoffs, footgun propagation. MAY for structural debt trigger, communication when blocked. Applied in the same pass as prose compression — two birds, one edit. + +--- + +## Phase 2: Permission Profiles + +**Problem it solves:** Different team roles need different permission scopes. A frontend developer shouldn't be editing Rust backend files. An infrastructure engineer shouldn't be changing React components. Without profiles, the agent has full access regardless of who's using it. + +**Source:** Claude Code's native `--profile` flag support. + +**Design decision:** Apps only — libraries with a single language rarely need role-scoped permissions. Each profile restricts Edit and Bash permissions to relevant file patterns. Always allows Read everywhere — restricting reads prevents the agent from understanding context. + +--- + +## Adoption Tiers + +**Problem it solves:** The full system is too much for a new project or a solo developer. Trying to implement everything at once creates setup fatigue and maintenance burden for features that aren't needed yet. + +**Source:** Direct experience — the Tauri app built up the system over weeks. The PHP library implemented it in 2 sessions. Different starting points, different tier needs. + +**Design decision:** Three tiers with clear "when to use" guidance. Minimal (CLAUDE.md + deny-dangerous hook) for getting started. Standard (+ skills + hooks + local CLAUDE.md files) for active development. Full (+ agent evals + CI + profiles) for long-lived projects with incident history. Each tier is self-contained — you don't need to plan for the next tier while implementing the current one. + +--- + +## Quarterly Audit + +**Problem it solves:** The system accumulates rules that outlive their usefulness. A footgun that was critical six months ago may have been fixed in code. A lesson that was important when the agent was less capable may now be default behaviour. + +**Design decision:** Periodic re-count, stale rule check, and the question: "if I removed this, would the model still do the right thing?" Rules that once helped become constraints as models improve. The system is designed to get smaller over time, not larger. diff --git a/00-1-ai-workflow-human-instructions_v1.3.md b/00-1-ai-workflow-human-instructions_v1.3.md new file mode 100644 index 0000000..a98c242 --- /dev/null +++ b/00-1-ai-workflow-human-instructions_v1.3.md @@ -0,0 +1,145 @@ +# AI Workflow Improvement — Human Instructions + +**Version:** 1.1 | 2026-03-14 +**Companion to:** `ai-workflow-improvement-plan-prime.md` (plan) and `ai-workflow-implement-prompts-prime.md` (prompts) + +--- + +## Reading Order + +1. **This file** — how to start +2. **The article** (`ai-workflow-ARTICLE-prime.md`) — why this exists, real implementation data +3. **The prompts** (`ai-workflow-implement-prompts-prime.md`) — what you run +4. **The plan** (`ai-workflow-improvement-plan-prime.md`) — full reference for every design decision +5. **The rationale** (`ai-workflow-design-rationale-prime.md`) — deep dives on why each section exists + +## What This Is + +A system that gives Claude Code a 5-step execution loop (READ → CLASSIFY → ACT → VERIFY → LOG) instead of a wall of rules.

If a decision changes, write a new ADR that supersedes the old one. + +--- + +## Phase 1 Enforcement + +### Permissions Deny List (settings.json) + +The strongest enforcement layer. The `.claude/settings.json` permissions deny list blocks tool invocations at the Claude Code level — before the command runs, before hooks fire. Claude Code refuses the tool call entirely. + +```json +"permissions": { + "deny": [ + "Bash(*git commit*)", + "Bash(*git push*)" + ] +} +``` + +**Why both permissions deny AND hooks:** + +Permissions deny handles binary prohibitions — actions that should NEVER happen regardless of context. `git commit` and `git push` are always human actions, full stop. + +Hooks handle pattern prohibitions — actions that are dangerous in specific forms but legitimate in others. `rm` is fine; `rm -rf /` is not. The hook inspects the command to decide. + +CLAUDE.md rules handle judgement calls — everything that needs context-aware reasoning. + +**When to use permissions deny vs hooks:** + +- **Permissions deny:** actions that should NEVER happen regardless of context. The deny list uses glob patterns (`Bash(*git commit*)`), not regex. It matches the entire command invocation, including chained commands. +- **Hooks:** actions that are dangerous in specific forms. The hook script uses regex/pattern matching to inspect command content and distinguish safe from unsafe variants. + +**Project-specific additions:** add `Bash(terraform apply *)` for infrastructure projects, `Bash(docker push *)` for container projects, or any other command that should require human hands. + +### Hooks + +| Hook | Type | Trigger | Purpose | +| -------------------------- | ------- | --------------------- | ------------------------------------------------------------------------------------ | +| Stop: build verification | Command | Every Claude turn | Stack-adaptive: detect modified file types via git diff, run relevant checks only | +| PostToolUse: auto-format | Command | After each Edit/Write | Format edited files by extension using the project's configured formatter | +| PreToolUse: deny-dangerous | Command | Bash tool calls | Block dangerous patterns: rm -rf, force push, pipe-to-shell, .env edits, hook bypass | + +### Hook Design Patterns + +**Exit code strategy for Stop command hooks:** + +Stop command hooks MUST exit 0 even when they find errors.

Use `git rev-parse --show-toplevel` for paths — relative paths break when cwd changes. +2. Put each Stop hook in its own array entry — combining command and prompt hooks causes double-firing. +3. Verify hooks exist at the project root — stale working directories create hooks in subdirectories. +4. Check `git diff` before running expensive checks. + +--- + +## Phase 1 Security Hardening + +### Deny Rules (PreToolUse hooks) + +Block known-dangerous patterns at the tool level. An instruction in CLAUDE.md saying "never use rm -rf" works ~70% of the time. A PreToolUse hook that blocks it works 100%. + +The deny script should block (exit 2 with error message): + +- `rm -rf` without explicit path scoping +- Direct `git push` to main/master/production +- `git push --force` (suggest `--force-with-lease`) +- `chmod 777` or overly permissive file permissions +- Pipe-to-shell patterns (`curl | bash`, `wget | sh`) +- `.env` file modifications +- `git commit --no-verify` or `git commit -n` + +**Note:** `git commit` and `git push` are blocked entirely by the permissions deny list in settings.json. The deny-dangerous hook handles the pattern-level variants (force push, no-verify) for cases where permissions deny alone isn't granular enough. + +**Project-specific deny rules:** add blocks for files that must be modified through tooling, not direct edit. Examples: binary-encoded dictionaries (must use encoder script), generated files (must use generator), lock files (must use package manager). + +### Pre-Commit Secret Scanning (Manual Setup) + +Set up gitleaks as a pre-commit hook. **This is a manual step — do not ask an AI agent to modify global git config.** + +```bash +# Install gitleaks for your platform +# Create ~/.git-hooks/pre-commit that runs: gitleaks git --staged --no-banner +# Set: git config --global core.hooksPath ~/.git-hooks +``` + +Note: `git config --global core.hooksPath` affects ALL repositories on the machine.
