Conciseness

The body is lean with no explanations of concepts Claude already knows — sections are pure operational guidance ("Use no more than three Context7 resolution or documentation calls per question", "Do not send API keys, passwords, credentials, or other secrets"). It is not a 5 because transport guidance is split between Step 1 ("Prefer the Context7 MCP tools...") and Step 5 ("Keep one transport for the question..."), a minor redundancy that could be trimmed.

Actionability

Guidance is fully executable: exact MCP tool names with arguments ("resolve-library-id", "query-docs") and copy-paste CLI commands ("npx ctx7@latest library <name> \"<user's question>\"", "npx ctx7@latest docs <libraryId> ..."), plus concrete failure handling ("npx ctx7@latest login or CONTEXT7_API_KEY"). This matches anchor 5's copy-paste-ready commands covering the common cases.

Workflow Clarity

Five clearly sequenced steps with a call budget, explicit error recovery for quota failures, and an uncertainty fallback ("state the uncertainty instead of guessing"). It falls short of anchor 5 because there is no feedback loop for a poor library match (e.g., re-resolving with a refined query) — checkpoints exist but the retry path is only implied by the call limit.

Progressive Disclosure

The skill is a compact single-purpose workflow (~56 lines) with well-organized sections (When to Use, Workflow steps) and no bundle files; nothing here warrants splitting into references. Per the simple-skill guidance, well-organized sections with no need for external references score 5.

Specificity

"Use current library and framework docs through Context7, preferring MCP tools with the CLI as a fallback" names the domain and one core action (fetch current docs via Context7) with transport detail, but does not list several distinct actions (e.g., resolving library IDs, querying docs). It matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than 4, which requires several listed actions.

Completeness

Both questions are answered explicitly: what ("Use current library and framework docs through Context7, preferring MCP tools with the CLI as a fallback") and when ("Activates for setup questions, API references, code examples, or named frameworks..."), with concrete trigger phrases. This matches the anchor 5 example structure of a clear what followed by an explicit 'Use when' clause.

Trigger Term Quality

Natural trigger phrases are present: "setup questions", "API references", "code examples", "named frameworks such as React, Next.js, or Prisma" — terms users would actually say. It falls short of anchor 5 because common variations like "documentation", "SDK", "CLI", or "how do I configure X" phrasings are not covered.

Distinctiveness Conflict Risk

The Context7 documentation-lookup niche is distinct with named triggers, so it sits between anchor 4 (minor overlap risk with closely related skills) and anchor 5. The broad trigger "code examples" could overlap with framework-specific or coding skills, keeping it below anchor 5's minimal-conflict bar.
