Conciseness

The body is mostly efficient but contains noticeable redundancy: 'Core Concepts' re-explains resolve-library-id and query-docs that Steps 1 and 3 then restate with their parameters, the three Examples each replay the identical 4-step flow, and 'Best Practices' repeats guidance already in Step 2 ('Version awareness', 'Be specific'). It fits the 'could be tightened' anchor rather than the 'minor instances of over-explanation' anchor because whole sections overlap, not just sentences. Nothing explains concepts Claude already knows, which keeps it above 2.

Actionability

For an instruction-only skill the guidance is fully concrete: exact tool names, exact parameters (libraryName, query, libraryId), the library-ID format ('/org/project'), selection criteria, a hard 3-call limit with an explicit fallback behavior, and three fully worked call sequences. This matches 'concrete, specific guidance' at the top anchor; there are no pseudocode or vague steps.

Workflow Clarity

The 4-step sequence (resolve → select → query → use) is clearly ordered with an explicit precondition ('You must obtain a Context7-compatible library ID before querying docs') and a termination guardrail (3-call limit with 'state the uncertainty'). It is not 5 because there is no error-recovery loop for the main failure mode — resolve-library-id returning no match or an ambiguous list — beyond the generic call limit.

Progressive Disclosure

No bundle files exist and none are needed; the single-file body is well organized into When to use / How it works / Examples / Best Practices with no monolithic inlined reference material. It is not 5 because the body (~82 lines) exceeds the simple-skill threshold and the redundant Examples section is content that could be consolidated or split, leaving minor organization gaps.

Specificity

The description names the domain and one composite concrete action — 'Use up-to-date library and framework docs via Context7 MCP instead of training data' — but does not enumerate the underlying capabilities (resolving library IDs, selecting matches, querying docs). This matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'; it is not a 4 because no additional distinct actions are listed, and not a 2 because the tool and action are concrete rather than generic.

Completeness

It explicitly answers both parts: 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'). The 'when' clause uses multiple concrete trigger phrases with examples, matching the top anchor exactly.

Trigger Term Quality

'Activates for setup questions, API references, code examples, or when the user names a framework (e.g. React, Next.js, Prisma)' gives good natural keyword coverage with named framework examples. It falls short of the 5 anchor because common variations such as 'documentation', 'docs', or 'up-to-date API behavior' as user-spoken phrases are only partially covered.

Distinctiveness Conflict Risk

Naming a specific tool (Context7 MCP) with framework-name triggers carves a clear niche with minimal conflict against unrelated skills. It is not a 5 because 'code examples' is a broad trigger that overlaps with any code-writing or documentation-fetching skill.
