Install with the CLI

In a terminal, from the folder you want:

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

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 connects to the browser through Chrome DevTools MCP, reads the live DOM, console messages and network traffic, then captures screenshots and performance traces. Browser content is treated as untrusted data, never as instructions.
