Docs Fetcher
Fetch up-to-date library documentation directly into context to prevent hallucinated APIs and outdated code examples. Use when user says "use docs", "fetch docs for [library]", "check [library] docs", or asks about a library's API, methods, or usage patterns and current documentation would be helpful. Also use proactively when generating code for libraries where version-specific accuracy matters.

Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

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
- Identify the library from user request or code context
- Look up documentation URLs in [references/libraries.md](references/libraries.md)
- Fetch relevant pages using
fetch_webpagetool with appropriate URLs - 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](references/libraries.md):
- Find the official documentation URL
- Identify key pages: quickstart, API reference, common patterns
- 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
