Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install browser-devtools-live-testing

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent drives Chrome DevTools through MCP to inspect the DOM, read console errors, analyse network requests and measure performance. It treats all page content as untrusted data. You get a check based on real runtime data, provided the chrome-devtools server is configured.
