Context7 API Documentation Fetcher

Retrieve up-to-date library documentation beyond Claude’s training cutoff.

Triggers

• Working with external libraries
• User asks about library APIs
• Implementing features with third-party packages
• Debugging library-specific issues
• “What’s the latest API for [library]?”
• “How does [library] handle [feature]?”

When to Use

PROACTIVELY use this skill when:

1. Working with ANY external library (React, Next.js, Supabase, etc.)
2. Users inquire about library APIs, patterns, or best practices
3. Implementing features dependent on third-party packages
4. Debugging library-specific issues
5. Information needed may exceed training data availability

DO NOT guess about library APIs – fetch current documentation instead.

API Endpoint

# Resolve library ID
curl -s "https://context7.com/api/v1/resolve?name=react" | jq

# Get library documentation
curl -s "https://context7.com/api/v1/context7/react?topic=hooks" | jq

# Search for specific patterns
curl -s "https://context7.com/api/v1/context7/nextjs?topic=server%20components" | jq

Common Libraries

Workflow

Step 1: Identify Library Need

When code involves external libraries, check if you have current knowledge.

Step 2: Fetch Documentation

# Get library context
curl -s "https://context7.com/api/v1/context7/[library]?topic=[topic]"

Step 3: Apply to Task

Use fetched documentation to provide accurate, current guidance.

Example Usage

User asks: “How do I use the new Next.js App Router?”

Response process:

1. Detect: Next.js App Router may have updated since training
2. Fetch: Context7 for nextjs/app-router documentation
3. Apply: Provide current, accurate implementation guidance

Integration with ClawdBot

Combine with:

• deep-research for comprehensive library comparisons
• code-reviewer to verify library usage patterns
• debugger to troubleshoot library issues

Fallback Behavior

If Context7 is unavailable:

1. Note limitation to user
2. Provide best-effort guidance from training
3. Recommend checking official docs
4. Suggest WebSearch for recent changes

Benefits

• Current: Documentation from recent releases
• Accurate: Direct from official sources
• Contextual: Focused on specific topics
• Efficient: No hallucinating deprecated APIs
