Automates and validates local web applications using Playwright for end-to-end testing and UI debugging.
This skill provides a comprehensive toolkit for testing local web applications through Python-based Playwright scripts. It streamlines the testing lifecycle by automatically managing server processes, capturing browser screenshots for visual debugging, and implementing a robust Reconnaissance-Then-Action pattern to ensure DOM stability before interaction. Whether you are working with static HTML or dynamic multi-server architectures, this skill helps Claude reliably navigate, inspect, and verify frontend behavior while maintaining a clean context window by utilizing specialized helper scripts.
