Webapp Testing
Webapp Testing is an Anthropic Agent Skill for checking local web apps with Playwright. Claude can start your dev server, drive the app in a browser, verify behaviour, debug the UI, take screenshots and read the browser logs.

- Ships

- Captures screenshots and browser console logs.
- Needs Python and Playwright for the scripts.
- The skill folder has SKILL.md, examples and scripts.
