Conciseness

The body is a tight, numbered procedural list with no padding or explanations of concepts Claude already knows; every line carries actionable instruction, matching the lean score-3 anchor.

Actionability

Although it is an instruction-only skill with no code, the guidance is concrete and specific: it enumerates exact inventory dimensions, evaluation criteria, and a required deliverable shape ('hypothesis, audience, format, owner, success measure, and evidence'). Per the code-vs-instruction note, absence of code is not penalized when guidance is actionable.

Workflow Clarity

A clear six-step sequence is given with quality guardrails (e.g. step 4 restricts fatigue diagnosis to time-series evidence, step 5 separates quality from performance). This is an analytical skill, not a destructive/batch operation, so the missing-validation cap does not apply.

Progressive Disclosure

The skill is well under 50 lines, single-purpose, and has no bundle files or external references, so per the simple-skills note a well-organized body scores 3. The numbered list plus closing guardrail paragraph is cleanly organized.

Specificity

Lists multiple concrete audit actions across modalities: 'paid-ad copy, images, video, hooks, concepts, format coverage, platform-native fit, message match, creative fatigue, accessibility, and policy', matching the score-3 anchor for several specific actions.

Completeness

Explicitly answers both 'what' (the enumerated audit targets) and 'when' via a clear 'Use for ...' trigger clause, satisfying the score-3 anchor for both.

Trigger Term Quality

The 'Use for creative audit, ad creative, creative fatigue, creative diversity, ad copy review, video review, image review, or production priorities' clause gives broad coverage of natural phrasings a user would actually say.

Distinctiveness Conflict Risk

The paid-ad creative-audit niche with platform-specific triggers is clearly distinguishable from other skills and unlikely to fire for the wrong one.
