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 questionquery: 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

11Activate this skill when the user:
12
13- Asks setup or configuration questions ("How do I configure Next.js middleware?")
14- Requests code involving libraries ("Write a Prisma query for...")
15- Needs API references ("What are the Supabase auth methods?")

20### Step 1: Resolve the Library ID
21
22Call `resolve-library-id` with:
23
24- `libraryName`: The library name extracted from the user's question
25- `query`: What to look up in the library's documentation (improves relevance ranking)
26
27### Step 2: Select the Best Match
28
29From the resolution results, choose based on:
30
31- Exact or closest name match to what the user asked for
32- Higher benchmark scores indicate better documentation quality
33- If the user mentioned a version (e.g., "React 19"), prefer version-specific IDs
34
35### Step 3: Fetch the Documentation
36
37Call `query-docs` with:
38
39- `libraryId`: The selected Context7 library ID (e.g., `/vercel/next.js`)
40- `query`: What to look up in the library's documentation, scoped to a single concept
41
42If 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.

49- Include relevant code examples from the docs
50- Cite the library version when relevant
