Conciseness

The body is lean and every sentence carries tool-specific knowledge Claude cannot already have ("APM coordinates work across AI assistants using planning documents, a file-based Message Bus and persistent work records"; the compact docs table; the metadata.json key list). There is no padding, no general-concept explanation, and no verbosity to trim, matching the 'lean and efficient; every token earns its place' anchor.

Actionability

Guidance is mostly executable: exact commands ("npm install -g agentic-pm", "apm --version", "apm status", "apm init -a agents claude"), a specific file with named keys (".apm/metadata.json for source, repository, releaseVersion..."), and concrete URLs to fetch. It is not 5 because some steps remain abstract ("Fetch the page relevant to the question", "verify behavior against the matching code or templates") without examples of how to do them.

Workflow Clarity

Sections 3 and 4 give clear numbered sequences with real checkpoints around destructive operations — "Obtain approval before modifying the installation", "verify preservation before cleanup", "check it with apm status" — matching 'clear sequence with most checkpoints present'. It is not 5 because there is no explicit validate-then-fix-then-retry feedback loop (e.g., what to do when apm status reports a problem after migration).

Progressive Disclosure

The skill is well organized into five clear sections with a compact, appropriately-inline documentation index acting as one-level-deep navigation, matching 'good structure; most content is appropriately placed'. It is not 5 because the body exceeds the under-50-line simple-skill threshold and the docs table plus role descriptions could plausibly live in a reference file if the skill grows.

Specificity

"Explain APM, answer documentation questions, inspect installations and help with setup or migration" lists several concrete actions (explain, answer doc questions, inspect installations, setup/migration), matching the 'several specific actions; minor gaps' anchor. It is not 5 because two actions are qualified by the generic "help with" and coverage is not comprehensive (no commands, file paths, or artifacts named).

Completeness

The 'what' is clear (four stated capabilities) but 'when' is entirely absent — there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because nothing in the description signals when to invoke the skill.

Trigger Term Quality

Keywords like "APM", "documentation", "installations", "setup", "migration" are relevant, but common variations users would naturally say are missing ("agentic project management", "agentic-pm", "upgrade", "APM CLI"), matching the 'some relevant keywords but missing common variations or synonyms' anchor. Not 4 because there is no 'Use when...' phrasing and synonym coverage is thin; not 2 because the terms are domain-relevant rather than purely generic.

Distinctiveness Conflict Risk

"APM" names a niche but collides with the far more common 'Application Performance Monitoring' expansion, and "answer documentation questions" / "help with setup or migration" overlap with generic documentation and setup skills, matching 'somewhat specific but could still overlap with similar skills'. Not 4 because the disambiguation is not strong enough to prevent mis-triggering.
