What it does

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 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
