Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-optimization-workflow

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 starts by measuring with Lighthouse, browser developer tools or production measurement, then targets the bottlenecks it finds. It tracks Core Web Vitals targets and checks that each fix really improves the measurement. A reference checklist is not included in this copy.
