Conciseness

A lean ~25-line body of two tight sections with zero concept explanation (it never explains what a CHANGELOG or release pipeline is) and no filler — every line is either a trigger or a rule. Matches anchor 5 ("every token earns its place"); anchor 4 is ruled out because there is nothing that could be trimmed.

Actionability

Rules like "Every breaking change ships with a CHANGELOG.md entry and a one-line migration note" are specific and checkable, but no example gh commands (e.g. gh api repos/{owner}/{repo}/traffic) or CHANGELOG entry template are provided — a real gap for a rule that mandates CLI evidence. Falls between anchor 3 ("missing key details") and 4 ("concrete code or commands with minor gaps"); since no commands exist at all, the gap is more than minor.

Workflow Clarity

A simple single-purpose reviewer skill with unambiguous activation triggers (exact paths including .github/workflows/build-release.yml) and individually clear rules; no multi-step process exists, so no validation checkpoints are needed. Scored below 5 because the arbitration path ("Final arbiter when... reviewers disagree") and the order of operations remain implicit.

Progressive Disclosure

Under 50 lines with well-organized sections and one external reference, [APM CEO persona](../../agents/apm-ceo.agent.md), but that path does not resolve (no agents/ directory exists at the referenced location). Good structure with a dangling navigation link is anchor 4 ("minor organization gaps"), not 5.

Specificity

The domain is named precisely ("project positioning, release communication, community-facing artifacts, or breaking-change decisions in microsoft/apm"), but the description states no actions the skill performs — no capability verbs at all. This matches anchor 2 ("Names the domain but actions are minimal or generic") rather than 3, which requires 1-2 concrete actions; it is above 1 because it is not entirely vague.

Completeness

The "when" is explicit ("Activate for changes to..." / "Triggers on..."), but the "what" is entirely absent — the description never says what the skill does once activated. This matches anchor 2 ("only 'when' is present without 'what'") exactly; anchor 3 is ruled out because it requires a clear "what".

Trigger Term Quality

"README, MANIFESTO, PRD, CHANGELOG, release workflows, and issue templates" plus "breaking-change" are concrete artifacts a maintainer would naturally mention. Missing file extensions (.md, .yml) and synonyms like "release notes" or "deprecation", so it falls short of anchor 5's comprehensive coverage but clearly exceeds anchor 3's "missing common variations".

Distinctiveness Conflict Risk

Scoped to "microsoft/apm" with repo-specific artifacts (MANIFESTO, PRD, issue templates, build-release.yml) giving it a clear niche. Minor overlap risk remains for common files like README.md and CHANGELOG.md that generic docs skills also target, keeping it below anchor 5.
