Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-optimization-4

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 from field data and a browser performance trace, then targets only the code tied to measured bottlenecks. You get focused changes and a re-run lab measurement to compare against.
