Install with the CLI

In a terminal, from the folder you want:

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

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 or fixes a Chrome extension following Manifest V3 rules: icons, service worker, content scripts and permissions. It also prepares the store listing and the pre-publish checklist for the Chrome Web Store.
