What This Skill Does

Runs adversarial UI tests in a real browser by analyzing git diffs or exploring an app freely. It checks functional correctness, accessibility, responsive layout, and UX heuristics, splitting work across parallel browser sessions when needed. Tests run locally or against deployed sites via Browserbase.

It plans and executes multi-angle test coverage, including adversarial and accessibility checks, in real browsers without writing test scripts or maintaining a test suite.

When to use it

  • Testing UI changes from a pull request before merging
  • Running accessibility audits with axe-core on localhost
  • Checking responsive layout across viewports after a redesign
  • Finding broken forms by submitting edge-case inputs like empty fields or special characters
  • Exploring a staging site to surface bugs before a release
