Conciseness

The body never explains concepts Claude already knows, but the opaque-ref list ("creator_ref, brand_ref, page_ref, shipping_ref, contact_ref, brand_asset_ref, hashtag_ref, promo_code_ref...") and the exact-authorization/send-gate caveats are repeated nearly verbatim in Skill Contract, Handoff Summary, Instructions steps 1/2/4, and the Example — a clear tighten-to-anchor-3 case ("mostly efficient but... could be tightened"). Not 2 because there is no concept padding or fluff, and not 4 because the duplication is systematic rather than a few minor instances.

Actionability

Concrete, executable guidance for an instruction-only skill: quoted invocation patterns ("Generate a TikTok brief for micro-influencers promoting [product], 1 review video..."), a worked Example with the expected output behavior, and specific mechanics like "Mark unresolved wording [needs source]" and "operation: propose" — matching anchor 4's mostly-executable-with-minor-gaps. Not 5 because the actual drafting guidance (master template, key-message phrasing) is delegated to reference files and inline guidance leans toward process governance over brief-writing specifics.

Workflow Clarity

A clear 5-step sequence (gather → generate → vary → save/route → prepare delivery) with explicit checkpoints: a "Done when" checklist, unresolved-placeholder blocking, and the claims dependency tuple. Not 5 because several checkpoints defer to external machinery (outreach-manager's gate, registry proposals) rather than including an inline validate-and-recover loop, leaving minor validation gaps per anchor 4.

Progressive Disclosure

Good structure against the actual bundle: the 106-line overview defers the 467-line template/variation material to the real references/brief-templates.md (its "#brief-variations-by-content-type" anchor exists) and creator-voice-intake.md, both one level deep and well-annotated in Reference Materials. Not 5 because multiple referenced paths (../../../references/skill-contract.md, ../../../CONNECTORS.md, sibling SKILL.md links) do not resolve within this bundle, leaving navigation gaps.

Specificity

"produces a structured creator brief with deliverables, key messages, creative direction, timeline, disclosure rules, and compensation terms" names the domain and comprehensively enumerates the output's concrete components, but describes a single core action rather than several distinct actions, matching anchor 4 ("lists several specific actions; minor gaps") better than anchor 5's multiple distinct actions.

Completeness

Explicitly answers both questions: what ("produces a structured creator brief with deliverables, key messages, creative direction, timeline, disclosure rules, and compensation terms") and when ("Use when the user asks to 'create an influencer brief' or 'write a campaign brief'") with concrete trigger phrases, exactly matching the anchor-5 example pattern. A cap of 3 does not apply since the 'Use when...' clause is present and explicit.

Trigger Term Quality

Includes quoted natural phrases users would actually say — "create an influencer brief", "write a campaign brief" — plus the core nouns (influencer/campaign/creator brief) and bilingual synonyms ("达人合作简报/创作者BF"), giving comprehensive natural-term coverage with synonyms as in anchor 5. Not 4 because no common variation a user would plausibly say is missing.

Distinctiveness Conflict Risk

Clear niche (creator/campaign briefs) with distinct triggers and an explicit disambiguation boundary — "Not for choosing how to split spend across creators — use budget-optimizer" — keeping conflict risk minimal as in anchor 5. It is not anchor 4 because it does not merely reduce overlap; it actively routes the nearest competing use case elsewhere.
