This skill should be used when the user asks about libraries, frameworks, API references, or needs code examples. Activates for setup questions, code generation involving libraries, or mentions of specific frameworks like React, Vue, Next.js, Prisma, Supabase, etc.

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 : 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 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
