Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-audit-3

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 records a performance trace, analyzes Core Web Vitals and network activity, checks accessibility, then looks for causes in the code and bundle. You get fixes ranked by measured impact.
