Conciseness

Mostly efficient, but with noticeable redundancy: the intro paragraph and the "Explain" section repeat the same rich-results/CTR rationale almost verbatim, and "Check" items (1)-(4) restate the same validation criteria as the "Code Review" section. This is more than the minor trimmable instances of the anchor 4 example, matching the "could be tightened" anchor 3.

Actionability

The Fix section provides a complete, valid, copy-paste-ready FAQPage JSON-LD block, a concrete validation tool URL (Google's Rich Results Test), and unambiguous field-level requirements ("acceptedAnswer" with "@type": "Answer" and "text"). The Check/Code Review steps give specific executable criteria covering the common cases.

Workflow Clarity

A clear Check → Fix → Code Review sequence with an explicit validation checkpoint ("Validate the markup using Google's Rich Results Test" and cross-referencing schema against visible page content). It stops short of anchor 5 because there is no explicit error-recovery feedback loop (what to do when the Rich Results Test reports errors, beyond the general fix steps).

Progressive Disclosure

The ~50-line body is a well-organized overview (Quick Reference, Check, Fix, Explain, Code Review) with a clearly signaled one-level-deep pointer — "For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`" — and that file exists and is on-topic (verified: it contains the same rule with good/bad code examples). No buried or nested references.

Specificity

The description lists three concrete, distinct actions — "adding FAQ sections to landing pages or blog posts", "generating FAQPage JSON-LD from existing Q&A content", and "validating that structured data on pages with FAQ sections is syntactically and semantically correct" — which comprehensively covers the skill's scope. It matches the anchor for multiple specific concrete actions rather than the anchor 4 example with only minor gaps.

Completeness

Both what and when are explicitly answered: the "Use when..." clause gives explicit trigger guidance, and the three gerund actions state exactly what the skill does, with concrete trigger phrases. It is not the anchor 4 case where the 'when' is weakly specified — the triggers name specific situations (adding FAQ sections, generating JSON-LD, validating structured data).

Trigger Term Quality

Good keyword coverage: "FAQ sections", "FAQPage", "JSON-LD", "structured data", "Q&A content", "landing pages", "blog posts" — all phrases a user would naturally say. A few natural variants are missing (e.g., "FAQ schema", "rich results", "schema markup"), so it falls just short of the comprehensive-synonym anchor 5.

Distinctiveness Conflict Risk

The FAQPage/FAQ-section niche is clear and mostly distinct from other SEO or schema skills, but the trigger "adding FAQ sections to landing pages or blog posts" could also fire for plain FAQ copy-writing requests that this schema-markup skill does not actually cover — a minor overlap risk consistent with the "mostly distinct" anchor.
