How to use it

This skill ships with Claude Code. Type it in any Claude Code session:

/run

Web App Testing: Tests a local web app with Playwright: checks behavior, screenshots and browser logs. Needs the app running and a browser.
Test Driven Development: Runs the red-green-refactor loop: write a failing test, make it pass with the minimum code, then clean up with tests still green.
Dogfood: Runs exploratory testing on a web app and writes a bug report with repro steps and screenshots or video. Needs agent-browser.
