Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install core-web-vitals-performance-audit

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 analyzes Chrome DevTools performance traces to find the cause of poor LCP, INP or CLS scores, and the resources that block rendering. It proposes targeted fixes. The skill is published by Cloudflare.
