Free web search via DuckDuckGo HTML (no API key, no per-query cost). Returns a list of {title, url, snippet}. Pass any URL to fetch_url for full content.

Fetch a single URL and return clean markdown. Handles HTML (via turndown+GFM), JSON (pretty-printed), and plain text. Cached locally. Optionally saves to docs/.md with YAML frontmatter (source URL, fetch date, content type).

Fetch README/docs for a library by name. Tries npm → PyPI → crates.io → Go → GitHub automatically. Accepts react, numpy, serde, owner/repo, etc. Optionally saves to docs/libraries/.md.

Language & API documentation search. Biases DuckDuckGo results to official docs sites (MDN, docs.python.org, pkg.go.dev, doc.rust-lang.org, etc.). Set fetch_top=true to retrieve the full markdown of the top hit instead of just the result list. LOCAL-FIRST: searches your docs/ folder first; only falls back to the web if no local match.

Browse and search the local docs/ folder. Three modes: (1) no args = list all saved docs, (2) { query } = keyword search across docs/, (3) { path } = read the full body of a specific doc by relative path or slug. Use this BEFORE going to the web — your project may already have the docs you need.
