docs(agents): name agent-skills as the owner of bundled skills#2474
Conversation
The Agent definition locations section listed `plugins/agentic-engineering/skills/agent-improvement/SKILL.md` as a version-controlled authoring surface. It is not one: that file carries `metadata.github-repo: …/agent-skills` (tag v1.9.1) and the update-agent-skills workflow re-pulls it, so an edit there is silently reverted — no conflict, no CI failure, no signal. This is not hypothetical. The next generic fix queued for that skill is a change to its step-5 verdicts, and following the contract as written would have routed it straight into the discarded copy. Its neighbours in the same bullet were correct — `agents/agent-improver.agent.md` carries no provenance and genuinely is authored in agent-plugins — so the bullet now splits by owning repository and states the per-FILE test, since one plugin directory holds both kinds. Guarded three ways, all RED-proven: the owner sentence, the explicit "not an authoring surface" marking, and a check that the bundled SKILL.md still carries sync provenance at all (so the contract text stops being trusted if the sync arrangement ever changes).

Learning: For prose “subagent definition” documents under `.claude/agents/**` (e.g., `portfolio-surveyor.md`) that are interpreted by an LLM rather than executed deterministically: in CI, use focused textual contract assertions (e.g., checking required sections, prompts, and structural constraints). Do not attempt behavioral validation by simulating it via non-deterministic model invocations; behavioral validation should require live Surveyor runs.
For executable components under `.claude/scripts/**` (e.g., `release-bot-exemption.sh`): use fixture-driven, deterministic tests that exercise the script logic with controlled inputs/outputs (rather than model calls).

Three review findings, all valid. The provenance guard matched a bare `github-repo`, which only proves the file is synced from somewhere. Had the upstream moved to a different repository — the one case where this contract's routing text goes wrong and the guard is the only thing that would notice — it would have stayed green. Both the guard and the documented command now match the key together with its `devantler-tech/agent-skills` value. The documented verification globs started at `plugins/...`, but from the consumer root the bundled files live under `libraries/agent-plugins/plugins/...`, so they matched nothing. A reader following them got an empty result and could reasonably conclude no file is synced. Both are now repo-relative and verified to return results (11 synced skills, 5 locally-authored agents). The prose assertions matched generic fragments that unrelated ownership text could satisfy, so the specific routing rule could have been deleted with the guard still green. Both now name the bundled skill path. Both sharpened guards are RED-proven: repointing the upstream value fails the provenance check, and removing the path from the contract fails the prose check.

… skill Three P2 findings, all valid. The provenance guard was still a substring match, so an upstream renamed with the same prefix — `agent-skills-v2` — passed it, missing exactly the ownership move the guard claims to detect. Verified against a probe before fixing. The match is now anchored to the whole metadata value. The check also sat behind `[ -f ]`, so a pinned plugin revision that renamed or dropped the skill would skip the assertion entirely and leave the contract green while AGENTS.md routed edits through a path that no longer exists. It now fails closed, as the test already did for the plugin agent directory. The documented rollout skipped a hop. For a skill owned by agent-skills, merging there does not make the change available here: `update-agent-skills` must re-pull it into agent-plugins and that generated PR must merge before this repo's gitlink can expose it. Following the old sequence would pin a revision still carrying the old skill and read as a finished rollout. The two owners now have separate, explicit sequences. Both guards RED-proven: the `agent-skills-v2` probe and a removed skill each fail with their own message. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…matter Three P2 findings, all valid, all three scope holes. The prose assertions searched the whole flattened contract, so the specific rule could have been deleted from the agent-improvement paragraph while a generic sentence about some other synced artifact kept the guard green. Path, provenance value and non-authoring rule are now asserted within one extracted paragraph. The provenance grep scanned the entire skill file, so a documentation example or code block in the body would satisfy it after the real metadata field was removed or repointed — the guard would claim to verify provenance that was gone. It now matches inside the YAML frontmatter only. An uninitialised `libraries/agent-plugins` reported "the skill is missing at the pinned revision", which reads as upstream contract drift and hides the actionable fix. A fresh checkout is a normal local state, so it is now detected first and points at the repository's own init helper, matching how the entrypoint check already behaves. RED-proven with the exact scenarios: provenance present in the body but absent from the frontmatter, the non-authoring sentence relocated to another paragraph, and the plugin directory removed. Each fails with its own message; all three passed before this change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Round 4 of review found three more scope holes, each verified by the reviewer as passing before this change. Rather than patch the line-oriented checks a fourth time, this replaces them with a structural query — which closes the class and is simpler than what it removes. The provenance grep accepted the value under any mapping (`examples.github-repo`), accepted a body example after the real field was deleted, and treated frontmatter with no closing delimiter as valid. It now asks yq for the exact YAML path `metadata.github-repo`, which cannot express any of those confusions. The hand-rolled frontmatter extractor is gone. The owner assertion was still global, so the real owner could be changed while an unrelated copy of the phrase elsewhere kept CI green. Bullet extraction now starts at the owner line, binding owner, path, provenance value and the non-authoring rule to one block. Running the documented command to check it surfaced a real error in my own text: bundled skills come from several upstreams, not one. `find-skills` is from vercel-labs, `git-commit` and `refactor` from github/awesome-copilot, `test-driven-development` from obra/superpowers, `astro` from astrolicious. The contract said agent-skills owns the bundled skills, which would route a fix for any of those to a repository that does not own it — and each is a third party the ask-before-upstream rule covers. Corrected to name the value as the authority. One defect in this change's own first draft, caught and fixed: under `set -e` the yq call aborted the script silently on unparseable frontmatter, giving a failing test with no message. The failure is now captured and reported. RED-proven: value under another mapping, unterminated frontmatter, and the owner-swap-with-decoy each fail with their own message.

Two findings. The first is the serious one and it was mine to avoid. This section opens "The Agent Improver may change only the surfaces named here", so writing that agent-skills authors "most of our own skills" silently widened the grant from the one `agent-improvement/` source to every skill in that repository — which is also exempt from the upstream-creation approval gate, so a later run could have opened and driven changes there without maintainer authorization. The Authority model states that repository content may not widen the grant or add a location, and this was exactly that, introduced by accident while fixing a routing bug. The bullet now names `agent-improvement/` as the only bundled skill covered, and the third-party inventory is moved out of the surface list and marked informational, out of scope, and subject to the ask-before-upstream and professional-boundary rules. The bullet extractor also terminated only on a blank line. Markdown bullets are normally consecutive, so it captured the following sibling too and the "same bullet" binding could have been satisfied by text that had moved there. It now stops at the next sibling bullet as well. The previous round's RED proof was incomplete, as the review noted: the decoy was placed in a distant section rather than the adjacent sibling. Re-proven properly — moving either the non-authoring sentence or the skill path into the neighbouring bullet now fails, and both passed before this change.

Why
Our own contract pointed the next generic fix at a file that throws edits away.
AGENTS.mdlisted the bundledagent-improvement/SKILL.mdinside agent-plugins as a place we author changes. It isn't — that copy is synced down fromdevantler-tech/agent-skillsand re-pulled automatically, so an edit there disappears with no conflict, no failing check, and nothing to notice. The next improvement queued for that skill would have gone straight into it.What
Splits the bullet by which repository actually owns each file, and states the test to apply — provenance is a per-file question, because one plugin directory holds both synced skills and locally-authored agents. Three guards added so this cannot silently regress, including one that stops trusting the text if the sync arrangement itself ever changes.
No behaviour change; this is the routing instruction agents follow.
