Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install core-web-vitals-fixes-2

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 diagnoses the weakest of LCP, INP and CLS, then applies fixes specific to each metric: the LCP element, long tasks, layout shifts. It follows a checklist for each. You get a diagnosis per metric and the fixes to apply.
