name: dig description: Look up documentation and source code for libraries and packages. Use when the user asks a question about a library, needs to understand a library's API, or when you need information about a library that you don't know about. Triggers on questions like "How do I use X library?", "What's the API for Y?", "Show me how Z library handles this", or when encountering unfamiliar library usage.

Dig

Look up library documentation by finding and exploring the library's source code repository.

Workflow

1. Check for Local Availability

First, check if the library source code already exists locally:

Copy# Check common locations
ls /tmp/cc-repos/{library-name} 2>/dev/null

If the library exists locally, skip to step 3.

2. Clone the Repository

If not available locally, find and clone the repository:

1. Search for the library's GitHub repository (most libraries are on GitHub)
2. Clone into the standard location:

Copymkdir -p /tmp/cc-repos
git clone https://github.com/{owner}/{repo}.git /tmp/cc-repos/{repo-name}

Common repository patterns:

• npm packages: Check package.json homepage or repository field, or search https://github.com/{package-name}
• Python packages: Check PyPI page for "Homepage" or "Source" links
• Go packages: The import path often is the repository URL
• Rust crates: Check crates.io for repository link

3. Research the Repository

Launch a Research agent (using the Task tool with subagent_type="Explore") to traverse the repository and answer the question.

Example prompt for the agent:

CopyExplore the repository at /tmp/cc-repos/{repo-name} to answer: {user's question}

Focus on:
- README and documentation files
- Source code structure
- API exports and public interfaces
- Examples and tests for usage patterns

4. Synthesize and Answer

Use the research findings to provide a clear, accurate answer to the user's question about the library.
