### `clean_extract`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Extract a full page or selected sections from a public URL or raw HTML as clean Markdown, with navigation, scripts and page chrome removed. Use it instead of a raw fetch when a task needs the text of documentation, an article, an RFC or another reference page: in a five-site benchmark the Markdown was 62% fewer estimated tokens than the HTML. Call the free clean_extract_outline first on a long page, then pass only the section ids you need. A call is charged only when it returns usable content; the first 3 usable extraction calls are free, total, then USD 0.05. Uncharged failures name upstream_timeout, upstream_http_error, bot_challenge, js_shell, empty_extraction, or sections_not_found. Recoverable structured data names fallback_used. Every success reports extraction_quality and extraction_content_ratio_band.
```

### `clean_extract_outline`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Free outline with section ids, headings, byte sizes, and a fingerprint, without page body text or payment. It never uses the free extraction allowance. Use it first to see what a long page contains and which sections are worth reading. A later clean_extract call can select sections and is charged only when it returns usable content. Uncharged failures name upstream_timeout, upstream_http_error, bot_challenge, js_shell, empty_extraction, or sections_not_found. Recoverable structured data names fallback_used.
```
