Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install chrome-extension-mv3-performance

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 writes, reviews or refactors an MV3 Chrome extension against 67 rules covering the service worker, content scripts, messaging and storage. It flags redundant calls and poorly managed lifecycles. You get a faster and more stable extension.
