Install with the CLI

In a terminal, from the folder you want:

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

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 first finds failing pages from field data, then proposes fixes for loading, responsiveness and visual stability. You get a per-metric diagnosis and a ranked list of fixes.
