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 Next.js middleware?") - 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`: The user's full question (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`: The user's specific question **Decompose multi-topic questions.** Context7 ranks results against a single intent. If the user's question covers more than one distinct concept (e.g. routing *and* auth *and* caching), issue a separate `query-docs` call per concept rather than one combined query — combined queries dilute ranking and return shallow results for each topic. Reuse the same library ID; you only resolve once. ### 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**: Pass the user's full question as the query for better results — but one *intent* per query. A specific single-concept query beats a specific multi-concept one. - **Version awareness**: When users mention versions ("Next.js 15", "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
