# Browser Tool

Control the user's Chrome browser tabs through the Officer Browser Relay and Chrome DevTools Protocol.

## Available Actions

- **list_tabs**: List all connected tabs with their title, URL, and ID.
- **screenshot**: Capture a screenshot of a tab. Returns the image directly. Use this when asked about page content.
- **navigate**: Navigate a tab to a URL. Requires `url`.
- **evaluate**: Run JavaScript in a tab and return the result. Requires `expression`.
- **page_info**: Get the title and URL of a tab.
- **activate**: Bring a tab to the foreground (focus it).
- **close**: Close a tab.

## Tips

- When asked about what's on a page, take a screenshot first.
- Use `evaluate` for extracting structured data from pages (DOM queries, reading text content, etc.).
- If no `tab_id` is provided, the first connected tab is used.
- Tab IDs can be obtained from `list_tabs`.
