Context7 Skill

Purpose

Fetches live, version-specific documentation for external libraries and frameworks using the Context7 API. Ensures you always get current API patterns instead of potentially outdated training data.

Golden Rule: Always fetch live docs for external libraries—training data may be outdated.

Quick Start

Recommended: Use ExternalScout Subagent

The ExternalScout subagent is the recommended way to fetch external documentation. It handles:

• Library detection
• Query optimization
• Documentation filtering and sorting
• Formatted results with code examples

Invocation:

Use ExternalScout to fetch documentation for [Library Name]: [your specific question]

Example:

Use ExternalScout to fetch documentation for Drizzle ORM: How do I set up modular schemas with PostgreSQL?

Alternative: Direct Skill Usage

You can also invoke the Context7 skill directly via bash:

# Step 1: Search for library
curl -s "https://context7.com/api/v2/libs/search?libraryName=LIBRARY&query=TOPIC" | jq '.results[0]'

# Step 2: Fetch documentation
curl -s "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=OPTIMIZED_QUERY&type=txt"

See SKILL.md for detailed API documentation.

Adding New Libraries

To add a new library to the registry:

1. Edit library-registry.md
2. Add entry under appropriate category:

   #### Library Name
   - **Aliases**: `alias1`, `alias2`, `package-name`
   - **Docs**: https://example.com/docs
   - **Context7**: `use context7 for library-name`
   - **Common topics**: topic1, topic2, topic3
   

3. (Optional) Add query optimization patterns
4. ExternalScout will automatically detect the new library
