- `get_page_text()` — read visible text on the current page
- `click_element(selector)` — click an element by CSS selector
- `fill_input(selector, text)` — type into a form field
- `press_key(key)` — press a keyboard key (Enter, Tab, Escape, etc.)
- `execute_js(code)` — run JavaScript with access to Playwright's `page`, `context`, and `browser`

### Email (via Inkbox)

## Guidelines

- Use the browser to navigate, read, and interact with websites.
