Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cross-browser-extension-development

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 works in the extension folder: content and background scripts, translations, Chrome, Firefox and Edge compatibility, and build and test commands. You get an extension that builds for each browser with up-to-date translations.
