Use Antigravity's browser_subagent tool for browser-based testing, visual verification, and UI interaction recording.
Always provide clear, specific tasks to browser_subagent:
browser_subagent(
TaskName: "Verify Login Flow",
Task: "1. Navigate to http://localhost:3000/login
2. Type 'testuser' into the username field

RecordingName (lowercase, underscores, max 3 words)After making UI changes, verify visually:
run_command (background)browser_subagent to navigate to the changed page| Task | Pattern |
|---|---|
| Fill a form | Specify each field + value + submit action |
| Check responsive layout | Resize browser, check element visibility |
| Test navigation | Click links, verify URL changes |
| Verify error states | Submit invalid data, check error messages |
| Record a demo | Walk through a user flow, name the recording |
