Web Browser Skill

You can browse the web using the browse:* tools. A managed browser window handles navigation and interaction.

Available Tools

  • browse:navigate — Navigate to a URL. Returns the page text AND a snapshot of all interactive elements with their CSS selectors. Start here. Params: url (string).
  • browse:snapshot — Get the interactive element snapshot for the current page without navigating. Use after a click to see what changed. No required params.
  • browse:screenshot — Take a screenshot of the current page. Returns an actual image you can see. Use to visually verify state. No required params.
  • browse:click — Click an element using a CSS selector from the interactive snapshot. Returns the updated snapshot after clicking. Params: selector (string).
  • browse:fill — Fill a form field by setting its value. Works for standard <input> and <textarea> elements. Params: selector (string), value (string).
  • browse:type — Type text using simulated keyboard input. Unlike browse:fill, this sends real key-press events through Chromium, so it works with contentEditable fields, rich text editors, and sites like Twitter/X that ignore programmatic value changes. Click the target element first to focus it, or pass selector to auto-focus. Params: text (string, required), selector (string, optional), clearFirst (boolean, optional).
  • browse:evaluate — Execute JavaScript in the page context. Use as a last resort — prefer the other tools. Params: script (string).
  • browse:show — Show the browser window to the user so they can see or interact with the page. Displays a "Done" banner. Use to present results, let the user review content, or hand off for manual steps. Params: url (string, optional), message (string, optional).
  • browse:login — Show the browser window so the user can log in manually. Params: url (string, optional), message (string, optional).

Workflow

  1. Navigate to the target URL with browse:navigate — the response includes all interactive elements with selectors
  2. Click or fill using the selectors from the snapshot — no need to probe the DOM
  3. After a click, the response includes the updated snapshot so you can see what changed
  4. Use browse:screenshot if you need to visually verify the page state
  5. Use browse:snapshot to refresh the interactive element list without navigating

Best Practices

  • Never probe the DOM manually with browse:evaluate to find elements — the interactive snapshot gives you everything
  • Use the CSS selectors exactly as shown in the snapshot (e.g. [aria-label="Like"])
  • When a site requires authentication, use browse:login to let the user sign in
  • Use browse:fill for standard form inputs (<input>, <textarea>, <select>). Use browse:type for rich text editors, contentEditable fields, or any site where browse:fill doesn't work (Twitter/X, Notion, Google Docs, etc.)
  • A typical interaction should be 2-3 tool calls: navigate → click → done
