Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-ssr-css-js

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 reviews your site to improve its performance: server-side rendering first, lighter client JavaScript, efficient CSS and optimization of the LCP, FID and CLS Core Web Vitals. You get concrete recommendations for each layer.
