Automate browser tasks and website testing using Playwright: detect dev servers, run responsive checks, fill forms, take screenshots and validate flows.
A general-purpose Playwright automation skill that writes and runs browser test scripts (saved to /tmp) to validate pages, responsive design, forms, login flows, and links. It auto-detects local dev servers, parameterizes URLs, and executes visible browser sessions for easy debugging.
Use this skill when you need to test a site or app interactively: cross-viewport checks, login flow validation, automated screenshots, broken-link scanning, or any browser-driven automation where seeing the browser helps debug.
Likely to be used with Claude Code / Node-capable agent runtimes that can execute Node scripts and control Playwright (agents with Node/JS execution support).
Playwright browser automation skill with no bundled scripts — all automation code is agent-generated at runtime. SKILL.md is well-documented with clear workflow steps, code examples for common patterns (screenshots, login flows, responsive testing), and a dev server detection helper. No security concerns found; writes to /tmp appropriately, no remote code execution or credential leakage risks.
Well-structured skill with good progressive disclosure (API_REFERENCE.md). SKILL.md is somewhat long with many inline examples that could be moved to references/. No scripts to test — all code is dynamically generated by the agent at runtime.
