Conciseness

The body is lean and each section contributes skill-specific framing ('A test suite is only worth the failures it would catch', the two failure modes, consequence-oriented reporting). Minor over-explanation: the causes of flakiness (timing guesses, shared state, real clocks) restate what Claude already knows.

Actionability

For an instruction-only skill, the guidance is concrete and executable: start from the test's name, check 'whether removing the feature would make it fail', check error paths, and the weak-vs-strong report phrasing example ('an empty cart throws in checkout and nothing would catch it'). Not a 5 because no inline example of a weak vs. strong assertion is given — that detail is deferred entirely to references.

Workflow Clarity

The 'Inspecting' section does give a rough sequence (name → do assertions pin the behavior → would removal fail → error paths and boundaries), but it is prose rather than checkpointed steps, and the actual staged procedure (the 2-minute pass and deep pass) lives in references/inspection-checklist.md rather than the body. Sequence present but checkpoints implicit.

Progressive Disclosure

The body is a concise overview with a dedicated Reference section pointing to four real, existing files in references/ (inspection-checklist.md, red-flags.md, assertion-quality.md, example-report.md), each clearly signaled with a one-line description. References are one level deep and easy to navigate, matching the top anchor.

Specificity

Lists several concrete inspection targets — 'assertion strength', 'coverage gaps', 'tests that pass while the feature is broken' — which matches the anchor for several specific actions with minor gaps. Not a 5 because it omits other natural test-quality actions (flaky detection, suite triage); not a 3 because it names three distinct actions rather than 1-2.

Completeness

Has a clear 'what' (inspect test quality across assertion strength, coverage gaps, false-green tests) but no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines.

Trigger Term Quality

Includes relevant keywords like 'test quality' and 'coverage gaps', but misses the common variations and synonyms users would naturally say — most notably 'flaky tests', plus 'unit tests', 'test suite', and 'false positives'. Falls between anchors 3 and 4, closer to 3 because the most natural trigger phrase for half the skill's scope (flakiness) is absent.

Distinctiveness Conflict Risk

Occupies a fairly distinct niche (test-quality inspection) with specific triggers (assertions, coverage, passing-while-broken), so it is mostly distinct. Not a 5 because terms like 'coverage gaps' and 'test quality' could overlap with a general code-review or testing skill.
