Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-audit-cwv

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 page with Lighthouse and web-vitals, finds bottlenecks, then ranks fixes into quick wins and longer projects. You get a report with the thresholds to reach and a performance budget.
