description: Use Context7 to fetch up-to-date library documentation. Activates when the user asks about libraries, frameworks, API references, or needs code examples — especially for setup questions, code generation, 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`: 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
### 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
- **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
