Tests in real browsers via Chrome DevTools MCP

browser-testing-with-devtools is an agent skill from Addy Osmani's agent-skills collection that uses Chrome DevTools MCP to give an agent a view into a real browser. The idea is to verify behavior at runtime rather than guess from static code. With the tool, the agent can see what the user sees, inspect the DOM, read console logs, analyze network requests and API responses, and capture performance data such as Core Web Vitals, paint timing and layout shifts. The skill lists when to use it: when building or changing anything that renders in a browser, when debugging layout, styling or interaction problems, when diagnosing console errors and warnings, when checking network calls, when profiling performance, when confirming a fix works in the browser, and when running automated UI tests through the agent. It says not to use it for backend-only changes, CLI tools or code that never runs in a browser. The skill includes a section on setting up Chrome DevTools MCP. It is listed on skills.sh, with its security audit results shown there. It suits developers and agents who work on web front ends and want evidence from the running page.
