Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-performance-optimisation

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 measurements to find what slows a page or API down: LCP, INP, CLS, bundles, images and requests. It proposes fixes such as code splitting, a caching strategy and k6 load testing.
