Conciseness

The body is lean and assumes Claude's competence — no library tutorials or background padding — with the one flaw that the multi-concept query guidance appears nearly verbatim in both Step 3 and the 'One topic per query' guideline, matching 'efficient; minor instances that could be trimmed'.

Actionability

Concrete, executable guidance throughout: named tool calls ('resolve-library-id', 'query-docs') with parameter lists, an example library ID ('/vercel/next.js'), and explicit selection criteria (benchmark scores, version-specific IDs), matching 'mostly executable guidance with minor gaps' — it stops short of a full worked example call with sample query strings.

Workflow Clarity

A clearly sequenced four-step workflow (resolve ID → select best match → query docs → use results) with per-step criteria; the operations are read-only so no validation checkpoint is required, placing it just below the explicit-validation anchor 5 at 'clear sequence with most checkpoints present'.

Progressive Disclosure

The skill is under 50 lines with no need for external references, and its content is well-organized into clearly labeled sections ('When to Use This Skill', 'How to Fetch Documentation', 'Guidelines'), which per the rubric's simple-skill note earns a 5; no bundle files exist to reference.

Specificity

Names the domain ('libraries, frameworks, API references') and concrete task types ('setup questions', 'code generation', 'code examples'), but never states what the skill actually does (fetch current documentation via Context7), so it falls at 'names domain and 1-2 concrete actions, but not comprehensive' rather than the level-4 'lists several specific actions'.

Completeness

The 'when' is explicit and detailed ('asks about libraries, frameworks, API references, or needs code examples'), but the 'what' — what the skill does when triggered — is only weakly implied and never stated, placing it between the 'only when without what' anchor (2) and a clear what/when pair (4).

Trigger Term Quality

Natural phrases users would say are present ('setup questions', 'code generation involving libraries', 'API references') plus concrete framework names (React, Vue, Next.js, Prisma, Supabase), matching 'good keyword coverage; a few natural terms missing' — it omits common variants like 'documentation', 'docs', or 'how do I use X'.

Distinctiveness Conflict Risk

The broad 'libraries, frameworks, code examples' domain overlaps with general coding and API skills, and the description never mentions Context7 or documentation fetching to carve out a niche; the specific framework mentions add some specificity, matching 'somewhat specific but could still overlap with similar skills'.
