context7-mcp

When the user asks about libraries, frameworks, or needs code examples, use Context7 to fetch current documentation instead of relying on training data. ## When to Use This Skill Activate this skill when the user: - Asks setup or configuration questions ("How do I configure a Next.js proxy?") - Requests code involving libraries ("Write a Prisma query for...") - Needs API references ("What are the Supabase auth methods?") - Mentions specific frameworks (React, Vue, Svelte, Express, Tailwind, etc.) ## How to Fetch Documentation ### Step 1: Resolve the Library ID Call `resolve-library-id` with: - `libraryName`: The library name extracted from the user's question - `query`: What to look up in the library's documentation (improves relevance ranking) ### Step 2: Select the Best Match From the resolution results, choose based on: - Exact or closest name match to what the user asked for - Higher benchmark scores indicate better documentation quality - If the user mentioned a version (e.g., "React 19"), prefer version-specific IDs ### Step 3: Fetch the Documentation Call `query-docs` with: - `libraryId`: The selected Context7 library ID (e.g., `/vercel/next.js`) - `query`: What to look up in the library's documentation, scoped to a single concept If the user's question spans multiple distinct concepts (e.g. routing and auth and caching), make a separate `query-docs` call per concept with the same library ID, unless the question is about how the concepts interact. Combined queries dilute ranking and return shallow results for each topic. ### Step 4: Use the Documentation Incorporate the fetched documentation into your response: - Answer the user's question using current, accurate information - Include relevant code examples from the docs - Cite the library version when relevant ## Guidelines - **Be specific**: Describe what to look up in the library's documentation, but keep each query to a single concept - **One topic per query**: Split multi-topic questions into separate `query-docs` calls. Resolve the library ID once, then query per concept, unless the question is about how the concepts interact - **Version awareness**: When users mention versions ("Next.js 16", "React 19"), use version-specific library IDs if available from the resolution step - **Prefer official sources**: When multiple matches exist, prefer official/primary packages over community forks
