Skills
Manage Browsers
Creates, lists, gets and deletes cloud browser sessions, with headless, stealth, profile, proxy and viewport options.
Execute Playwright Code
Runs Playwright TypeScript code against a Kernel browser session to automate clicks, form fills and page reads.
Computer Action
Sends mouse, keyboard and screenshot controls to a browser session, for computer-use agents that act on pixels.
Manage Profiles
Saves and reuses browser profiles with cookies and logins, so agents stay signed in to sites across sessions.
Manage Replays
Starts, stops and lists video replay recordings of a browser session, for reviewing and debugging agent runs.
