Webapp testing skills for Codex and AI agents
A testing skill should make the agent behave like a practical QA engineer, not like a unit-test generator that never opens the product.

Browser checks matter
For web apps, a large class of bugs only appears in a real browser: broken buttons, hidden overflow, failed redirects, bad mobile layout, missing focus, and runtime console errors.
A webapp testing pack should push the agent to run or create browser checks, capture screenshots, and report exactly what was verified.
Use it before every visible release
Use webapp testing with Playwright tests, mobile UI QA, form validation QA, checkout QA, and bug reproduction before shipping user-facing changes.
Good final reports are specific
The final response should say which routes were opened, which viewport sizes were checked, what failed, what was fixed, and what risk remains.
