Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-audit-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 first checks that the Chrome DevTools MCP tools are available. It records a performance trace, analyzes the Core Web Vitals, the network and an accessibility snapshot, then reviews the framework, the bundler and dead code. You get a diagnosis and optimization leads.
