Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install core-web-vitals-fixes

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 measures the three metrics first, using CrUX data when available, then diagnoses the cause: LCP image, slow interaction or layout shift. It applies targeted fixes, with guidance per metric and for Next.js.
