Conciseness

Mostly efficient with no explanations of concepts Claude already knows, but the scope boundary ("checks only"; repair → `landing-optimizer`; RQS → `ad-account-auditor`) is restated three times — intro paragraph, the Instructions closing paragraph, and Next Best Skill — and the intro duplicates the frontmatter description nearly verbatim. Fits anchor 3 ("could be tightened"); not 4 because the repetition is recurring across sections, not a minor instance.

Actionability

Includes one fully executable command (`python3 "${CLAUDE_PLUGIN_ROOT}/scripts/connectors/firecrawl.py" scrape <landing-url> --mobile`) plus concrete per-check Pass/Partial/Fix criteria and explicit Measured/Estimated labeling rules. Fits anchor 4 (mostly executable, minor gaps); not 5 because the five checks are directive prose without per-check commands or examples beyond the single scraper invocation.

Workflow Clarity

Eight clearly sequenced steps, an input-confirmation step with an explicit NEEDS_INPUT stop path, a four-item "Quality bar before handoff" checklist, and a feedback loop ("If any item fails, fix it or report it in the handoff — do not ship silently"). Matches anchor 5 with explicit validation checkpoints and error-recovery guidance; not 4 because checkpoints are explicit rather than implied.

Progressive Disclosure

Well-organized sections (Quick Start, Skill Contract, Data Sources, Instructions, Save Results, Reference Materials, Next Best Skill) with clearly signaled, one-line-annotated references. Fits anchor 4; not 5 because every referenced file ([skill-contract.md](../../../references/skill-contract.md), [CONNECTORS.md](../../../CONNECTORS.md), [scripts/connectors/README.md](../../../scripts/connectors/README.md)) resolves outside the skill directory and no bundle files (references/, scripts/, assets/) exist to verify, so navigation rests on unverifiable cross-repo paths.

Specificity

Lists five concrete checks — "message-match gaps, above-the-fold check, page-speed read, form-friction count, mobile-render flags" — with a concrete output ("a pass/fix punch list"), matching the comprehensive-coverage anchor. Not 4: the skill's actions are fully enumerated with no coverage gaps.

Completeness

Explicitly answers both: what ("produces an ad↔page continuity report — ... as a pass/fix punch list") and when ("Use when the user asks to...") with concrete trigger phrases. Matches the anchor-5 example structure exactly; the 4-anchor's "'when' could be more explicit" does not apply.

Trigger Term Quality

Three quoted natural trigger phrases ("pre-launch check the landing page", "run a Quality-Score preflight", "verify ad-to-page message match before launch") plus domain synonyms (message match, form friction, mobile render). Not 4: natural-phrase coverage is comprehensive with synonyms rather than "a few natural terms missing".

Distinctiveness Conflict Risk

Clear niche (landing-page preflight against ads) with explicit negative triggers routing overlaps away: "Not for redesigning or rewriting the page — use landing-optimizer; not for scoring the account or the RQS — use ad-account-auditor". Minimal conflict risk; the 4-anchor's "minor overlap risk" is already disclaimed.
