Conciseness

Efficient overall — it never explains concepts Claude already knows — but rhetorical flourishes spend tokens on style: 'readers have learned to smell it', 'an opinion wearing a methodology costume', 'fabrication with extra steps', and the winding 'When NOT to use' sentence about how-to content. Not 5 because those passages could be tightened without losing guidance; not 3 because nothing is padded and every section delivers method rather than filler.

Actionability

For an instruction-only skill the guidance is fully concrete and executable: verification steps ('cross-check the spec against the manufacturer's current listing, note the date'), exact honesty language ('across roughly 1,400 owner reviews' vs 'owners say'; 'none claimed'), per-case schema rules ('ItemList for the picks, Article for the piece'), FTC placement specifics ('near the picks, in body-size text, before or beside the first affiliate link'), a 7-step workflow, and a fillable template with a worked example one level deep in references/methodology-block-template.md.

Workflow Clarity

Seven clearly sequenced steps with a sound ordering rationale ('Set the criteria first… so the criteria cannot quietly bend toward a favored pick') and a failure-patterns list that functions as a checklist. Not 5: validation exists as rules — the block-honesty rule ('A block that claims a tier the piece did not use is the same lie') and 'Match the markup to the claims' — but the workflow sequence lacks explicit verify-before-proceeding gates.

Progressive Disclosure

The body is a genuine overview with two well-signaled, one-level-deep references (references/evidence-tiers.md, references/methodology-block-template.md), both verified to exist and self-contained with no further nesting; tier depth and the fillable template are appropriately split out, and the 'Reference files' section lists both with descriptions for easy navigation.

Specificity

Lists multiple concrete actions — 'Produce honest product reviews and buying guides', 'set up a review methodology', 'add evidence disclosure to review content', 'align reviews with Google's reviews system or FTC affiliate disclosure expectations', 'decide when Review and Product schema are honest to use' — comprehensively covering every capability the skill body delivers. Not 4: there is no gap in action coverage; the verbs are specific and the domain is fully spanned.

Completeness

Explicitly answers both questions: what — 'Produce honest product reviews and buying guides without fabricated first-hand experience, using disclosed evidence tiers' — and when — 'Use this skill whenever the user wants to…' followed by a concrete 'Triggers on…' phrase list. This matches the 5 anchor (what AND when with concrete trigger phrases); not 4 because the when-clause is already maximally explicit.

Trigger Term Quality

'Triggers on product review, buying guide, best-of list, review methodology, evidence basis, hands-on testing, we tested, affiliate review site, review disclosure, methodology block, original research, reviews system' — twelve natural terms including synonyms (buying guide / best-of list; hands-on testing / we tested) plus behavioral triggers ('claims testing that did not happen'). Not 4: no natural phrasing a user would say in this domain is conspicuously absent.

Distinctiveness Conflict Risk

Clear niche — the evidence and disclosure layer of review content — with distinct triggers ('we tested', 'methodology block', 'best-of list', 'affiliate review site') unlikely to fire for general writing or SEO skills. Not 4: the description scopes itself to review evidence rather than content writing generally, keeping overlap risk minimal.
