Conciseness

The body is mostly efficient procedural instruction, but the one-topic-per-query rule is stated three times ("scoped to a single concept", "keep each query to a single concept", "One topic per query: Split multi-topic questions"), version preference appears twice (Step 2 and "Version awareness"), and the "When to Use This Skill" section duplicates the frontmatter description. This fits anchor 3 ('mostly efficient but could be tightened') rather than 2, since there is no conceptual padding or explanation of things Claude already knows.

Actionability

Concrete, executable guidance throughout: named tools ("Call `resolve-library-id` with", "Call `query-docs` with"), their exact parameters ("libraryName", "query", "libraryId"), and an example library ID ("/vercel/next.js"). It falls short of anchor 5 only in lacking a literal worked example of a call, e.g., resolving and querying Next.js proxy configuration end-to-end.

Workflow Clarity

A clear four-step sequence (resolve library ID → select best match → fetch docs → use docs) with explicit selection criteria in Step 2 (name match, benchmark scores, version preference). It misses anchor 5 because there are no error-recovery feedback loops for failure cases, such as what to do when resolution returns no match or ambiguous results.

Progressive Disclosure

This is a short, single-purpose skill with no external references needed, and the body is organized into clear, well-labeled sections (When to Use, How to Fetch Documentation with four sub-steps, Guidelines). Per the simple-skill guidance, well-organized sections alone warrant a 5 here.

Specificity

The description names its domains ("libraries, frameworks, API references, or needs code examples") but states no concrete actions the skill performs — what it actually does (fetch current documentation via Context7) never appears. It matches anchor 2 ('names the domain but actions are minimal or generic') rather than 3, which requires 1-2 concrete actions.

Completeness

The 'when' is explicit and detailed ("should be used when the user asks about libraries... Activates for setup questions"), but the 'what' is entirely absent — the description never says what the skill does. This matches anchor 2 ('only when is present without what') and cannot be 3, which requires a clear 'what'.

Trigger Term Quality

Good natural keyword coverage including "setup questions", "code generation", "code examples", and named frameworks ("React, Vue, Next.js, Prisma, Supabase"), but it omits central synonyms like "documentation" or "docs" that users would naturally say. Not 5 because coverage is not comprehensive, but clearly better than 3's 'missing common variations'.

Distinctiveness Conflict Risk

The library/framework documentation niche is somewhat specific, but broad triggers like "needs code examples" and "code generation involving libraries" would fire on many general coding requests, creating real overlap with generic coding skills. This is more than 'minor overlap risk' (anchor 4), so anchor 3 fits best.
