# Web Fetch

Fetches web content with cascading fallback strategies to get the cleanest possible text.

## Strategies (in order)

1. **Markdown version** — Appends `.md` to the URL (works on GitHub, many docs sites)
2. **llms.txt discovery** — Checks `/llms.txt` at the root (sites that publish LLM-friendly content)
3. **Plain text request** — Sends `Accept: text/plain` header
4. **HTML strip** — Fetches HTML and strips tags, scripts, and styles

## Output

Returns the text content with a note indicating which strategy succeeded.
