Conciseness

The body is terse bullet lists with no concept-padding (it never explains what a README, CHANGELOG, or incumbent is) and pointed phrasing like "No vibes-based assertions." Every token earns its place and it assumes Claude's competence. It is not level 2 because there is no unnecessary explanation or padding to trim.

Actionability

Rules give concrete, specific guidance: "Ground every claim in `gh` CLI evidence (stars, issues, PRs, releases, traffic, contributors)", "Every breaking change ships with a `CHANGELOG.md` entry and a one-line migration note", and exact file paths like `.github/workflows/build-release.yml`. Per the instruction-skill note, absence of code is not penalized when guidance is this actionable. It is not level 2 because key details (evidence categories, file targets, prioritization order) are present, not missing.

Workflow Clarity

This is a single-purpose review/arbiter skill under 50 lines with no destructive or batch operations, so the simple-skills allowance applies: the single action (apply the key rules when triggered, arbitrate disagreements) is unambiguous and the content is clearly organized into "When to activate" and "Key rules". It is not level 2 because no validation checkpoint is required for this non-destructive context, so the cap does not apply.

Progressive Disclosure

The body is a short overview split into two well-organized sections with one clearly-signaled, one-level-deep reference ([APM CEO persona](../../../.apm/agents/apm-ceo.agent.md)). There is no monolithic wall of text and no nested references. It is not level 2 because structure and signaling are already clean for a sub-50-line skill with no bundle files.

Specificity

The description names a concrete domain ("project positioning, release communication, community-facing artifacts, or breaking-change decisions") and specific artifacts (README, MANIFESTO, PRD, CHANGELOG, release workflows, issue templates), but "Activate for changes to..." is a trigger rather than a concrete capability — it never states what the skill actually does (review, enforce, arbitrate). It is above level 1 because the domain is specific rather than vague, but below level 3 because no concrete actions are listed.

Completeness

Both the scope (what: "changes to project positioning, release communication, community-facing artifacts, or breaking-change decisions in microsoft/apm") and the trigger guidance (when: "Triggers on README, MANIFESTO, PRD, CHANGELOG, release workflows, and issue templates") are explicitly stated. It is not level 2 because the "when" is explicit rather than implied, satisfying the explicit-trigger requirement.

Trigger Term Quality

"Triggers on README, MANIFESTO, PRD, CHANGELOG, release workflows, and issue templates" plus "breaking-change decisions" gives good coverage of natural, concrete terms a contributor would reference. It is not level 2 because the terms are specific named artifacts rather than generic categories with missing variations.

Distinctiveness Conflict Risk

Scoping to "microsoft/apm" and to a distinct set of strategic artifacts/concerns gives it a clear niche unlikely to conflict with other skills. It is not level 2 because the trigger set is repo-specific and tightly bounded rather than broadly overlapping.
