Docs Fetcher

Fetch current documentation for libraries to ensure accurate, up-to-date code generation.

Workflow

Trigger Detection

Activate this skill when:

• User explicitly requests: "use docs", "fetch docs for X", "check X documentation"
• User asks about specific API methods, parameters, or patterns for a supported library
• Generating code where version-specific accuracy is critical

Execution Steps

1. Identify the library from user request or code context
2. Look up documentation URLs in references/libraries.md
3. Fetch relevant pages using fetch_webpage tool with appropriate URLs
4. Use fetched content to inform code generation or answer

Fetching Strategy

For comprehensive coverage, fetch multiple pages:

fetch_webpage(urls: [
  "https://fastapi.tiangolo.com/tutorial/dependencies/",
  "https://fastapi.tiangolo.com/advanced/advanced-dependencies/"
])

For quick lookups, fetch the most relevant single page.

Adding Libraries

To add a new library, edit references/libraries.md:

1. Find the official documentation URL
2. Identify key pages: quickstart, API reference, common patterns
3. Add entry following the existing format

Limitations

• Fetches only explicitly listed URLs (no recursive crawling)
• Some documentation sites may block or limit fetches
• Very large pages may be truncated
• No version pinning — fetches current docs

When NOT to Use

• General programming questions not library-specific
• Libraries not in the mapping (inform user, suggest they provide URLs)
• Simple questions where training knowledge is sufficient
