Conciseness

The body is dense with harness-specific instruction and explains nothing Claude already knows, but contains minor trimmable material: the five-line agency narrative opener ("A good agency would not hand them a twenty-field form…"), maintainer-facing HTML comments about the shared block's copy/parity procedure, and the asking rule restated in "The one rule", Step 2, Decision Rules and Quality Checks. It is above the score-3 anchor (mostly efficient) but not every token instructs, so it falls short of the lean score-5 anchor.

Actionability

Guidance is fully executable for an instruction-only skill: a fact-sheet table with a worked example row, literal output text for each file (e.g. "stage: intake, ids none/[], updated_by: ad-management-intake"), a copy-paste labelling table with exact strings like "(assumed from <source> — not confirmed)", a complete example assumptions message, and full sample decisions.md entries. This matches the score-5 anchor — concrete templates covering the common cases — rather than score 4's 'minor gaps'.

Workflow Clarity

Steps 0–6 are explicitly sequenced (resume → gather → fact sheet → Section A → Section B → state assumptions → write and hand over), with a corrections sub-procedure, an end-of-run Quality Checks checklist (including "ads/ passes the contract validator"), and a Failure Modes table mapping symptom → cause → fix that serves as error-recovery feedback loops. The batch write operation is covered by validation checkpoints, matching the score-5 anchor and exceeding score 4's 'most checkpoints'.

Progressive Disclosure

SKILL.md is a well-organized overview that routes to three real, one-level-deep bundle files — [references/gooseworks-adapter.md], [references/local-adapter.md] chosen by mode, and references/business-types.md for per-type detail (all verified present, 45–95 lines each) — with appropriately split content and a section explaining that paths are relative to the skill's own folder. The external meta-ad-manager contract is clearly located rather than nested, so navigation matches the score-5 anchor instead of the score-4 'minor organization gaps'.

Specificity

The description lists multiple concrete actions — "Researches the brand first, states what it assumes, and asks only what it cannot infer", "at most four questions a turn", "Writes the brand's stable facts (ads/brand.md), the campaign brief, and a log of what was asked vs assumed" — with concrete file outputs, giving comprehensive coverage of the skill's capabilities. It clearly exceeds the score-4 anchor (only minor gaps) and matches the score-5 anchor for multiple specific concrete actions.

Completeness

It explicitly answers both parts: what it does ("Researches the brand first, states what it assumes, and asks only what it cannot infer… Writes the brand's stable facts… the campaign brief, and a log") and when to use it ("Use it when someone wants to run Meta ads and the brand's ad facts are not yet recorded"), matching the score-5 anchor for clear what-and-when with concrete triggers. Not score 4, since the 'when' clause is already fully explicit and conditional.

Trigger Term Quality

"Use it when someone wants to run Meta ads" plus "brand's ad facts are not yet recorded" gives a good natural trigger phrase, but coverage misses common synonyms users say — "Facebook ads", "Instagram ads", "advertising", "paid social". It sits above the score-3 anchor (relevant keywords present, some variations missing) but below score 5, which requires comprehensive synonyms.

Distinctiveness Conflict Risk

"The intake stage of a Meta ad harness" plus the condition "the brand's ad facts are not yet recorded" carves out a clear niche that disambiguates it from sibling ad skills (strategy, launch) covering the same 'run Meta ads' trigger. This matches the score-5 anchor (clear niche, distinct triggers, minimal conflict risk) rather than score 4's 'minor overlap risk with closely related skills'.
