Anthropic's skill for testing web applications that run on the user's own machine by writing Python Playwright scripts.
What the skill teaches
Anthropic's skill for testing web applications that run on the user's own machine by writing Python Playwright scripts. For a static HTML file the agent reads the markup to find selectors; for a dynamic app it starts the servers with a bundled helper if needed, waits for the page to finish loading, takes a screenshot or inspects the DOM to find selectors, and only then clicks, fills and checks. It drives headless Chromium and can capture screenshots and browser console output. Example scripts cover finding elements, automating local files and logging the console. The agent is told to call helper scripts with --help rather than reading their source.
