Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install browser-extension-builder

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 follows the architecture, pitfall and validation references to build the extension, from popup to service worker. You get a structured extension, with permission and store-publishing checks.
