Conciseness

The body is lean, assumes Claude's competence (no explanation of what libraries or documentation are), and every section carries operational content. Minor duplication keeps it from 5: the Core Concepts bullet definitions of 'resolve-library-id' and 'query-docs' restate information given again in Steps 1 and 3, and could be merged.

Actionability

Fully concrete, executable guidance: exact MCP tool names, exact parameter names and values ('libraryName: "Next.js"', 'libraryId: "/vercel/next.js"'), selection criteria, a hard 3-call limit, and three worked examples covering common cases (Next.js, Prisma, Supabase). This is copy-paste-ready instruction of the kind the score-5 anchor describes.

Workflow Clarity

A clear four-step sequence with an explicit gate ('Do not call query-docs without a valid library ID'), selection criteria as a checkpoint, and a fallback when the answer stays unclear after 3 calls. Not 5: there is no true feedback/recovery loop — e.g. what to do when resolve-library-id returns no usable match is unaddressed — and no explicit verification that fetched snippets actually answer the question.

Progressive Disclosure

The skill is a single self-contained SKILL.md with no references/, scripts/, or assets/ bundle, and nothing in it clearly belongs in a separate file; headers (Core Concepts, When to use, How it works, Examples, Best Practices) make navigation easy. Not 5: the body runs ~84 lines (above the under-50-line simple-skill exception), and Core Concepts/Examples sections could arguably be split out if the skill grows.

Specificity

The description names the domain ("library and framework docs") and one concrete action ("Use up-to-date... docs via Context7 MCP instead of training data") with a specific mechanism, but does not list multiple distinct actions like the score-4/5 anchors ('Extracts text, fills forms, converts pages'). Not score 2, because the action named is concrete and tool-specific rather than generic ('Processes PDF files').

Completeness

Explicitly answers both: what ("Use up-to-date library and framework docs via Context7 MCP instead of training data") and when ("Activates for setup questions, API references, code examples, or when the user names a framework"), matching the score-5 anchor's structure of concrete 'what' plus explicit trigger phrases.

Trigger Term Quality

Good natural keyword coverage: "setup questions, API references, code examples" plus concrete framework names ("React, Next.js, Prisma") that users would naturally say. Not 5, because common variations like 'documentation', 'latest docs', or '.docs' style phrasings and additional library names are missing; not 3, since several natural trigger phrases beyond the domain noun are present.

Distinctiveness Conflict Risk

The Context7 MCP niche is clear and the triggers are fairly distinct, but broad triggers like "code examples" and "API references" could overlap with general web-research or API-reference skills. Mostly distinct with minor overlap risk — the score-4 anchor; the score-5 anchor requires minimal conflict risk across the full trigger set.
