context7-docs - SKILL.md Agent Skill

name: context7-docs description: Fetch up-to-date, version-specific documentation and code examples for any library or framework. Use this skill when you need current documentation for a library, framework, or API that may have changed since your training data. Triggers on requests like "use context7", "get docs for [library]", "how do I use [library] with context7", or when you encounter potentially outdated API usage.

Context7 Documentation Retrieval Skill

This skill provides access to Context7, a service that delivers up-to-date, version-specific documentation and code examples directly into your context. Use this instead of relying on potentially outdated training data.

When to Use This Skill

When working with libraries/frameworks that update frequently (React, Next.js, Supabase, etc.)
When the user explicitly requests "use context7" or "get docs"
When you encounter code that might use deprecated APIs
When implementing features with libraries you haven't used recently
When the user asks about specific library versions

How to Use Context7

Method 1: Direct API Query (Recommended)

Use the Context7 API to fetch documentation:

# Resolve library ID first
curl -s "https://context7.com/api/v1/search?query=LIBRARY_NAME" | head -20

# Then fetch documentation with the resolved ID
curl -s "https://context7.com/api/v1/LIBRARY_ID/llms.txt?tokens=5000"

Method 2: Web Fetch

If bash is not available, use web fetch:

Fetch: https://context7.com/api/v1/search?query=LIBRARY_NAME
Then: https://context7.com/api/v1/LIBRARY_ID/llms.txt?tokens=5000

API Reference

Search for Libraries

GET https://context7.com/api/v1/search?query={library_name}

Returns a list of matching libraries with their IDs.

Get Documentation

GET https://context7.com/api/v1/{library_id}/llms.txt?tokens={max_tokens}

Parameters:

library_id: The resolved library identifier (e.g., "vercel/next.js", "supabase/supabase-js")
tokens: Maximum tokens to return (default: 5000, max: 15000)

Example Library IDs

Common libraries and their Context7 IDs:

Next.js: vercel/next.js
React: facebook/react
Supabase JS: supabase/supabase-js
Tailwind CSS: tailwindlabs/tailwindcss
Three.js: mrdoob/three.js
Framer Motion: framer/motion
Zustand: pmndrs/zustand

Workflow

Identify the library the user needs help with
Search for the library if you don't know its exact Context7 ID
Fetch documentation with an appropriate token limit
Use the retrieved docs to provide accurate, up-to-date answers

Token Limit Guidelines

Quick reference: 2000-3000 tokens
Standard usage: 5000 tokens (default)
Comprehensive docs: 10000-15000 tokens
Balance: Use smaller limits for simple questions, larger for complex implementations

Example Usage

When user asks: "How do I set up Supabase authentication in Next.js?"

Fetch Supabase docs:

curl -s "https://context7.com/api/v1/supabase/supabase-js/llms.txt?tokens=5000"

Fetch Next.js docs:

curl -s "https://context7.com/api/v1/vercel/next.js/llms.txt?tokens=5000"

Combine the retrieved documentation with your knowledge to provide an accurate answer.

Notes

Context7 provides documentation scraped from official sources
Documentation is kept up-to-date automatically
Free tier: 50 queries/day for personal use
Focus on code snippets and practical examples over theory
