Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install web-performance-core-web-vitalsWith 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 loginThe agent measures current performance, identifies problems, ranks them by priority, applies fixes (images, JavaScript, CSS, caching) and then checks the gains. You get an optimization plan based on measurements.
