Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install core-web-vitals-optimization-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 measures the three metrics, tackles the highest-impact fixes first (images, preloading the LCP resource, critical CSS, JavaScript splitting, reserved space), then verifies with Lighthouse CI and field data. You get a prioritized list of fixes and their expected effect.
