Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install browser-extension-manifest-v3

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 proposes an extension architecture, writes the Manifest V3 file, the content scripts and the communication between them, then covers the popup interface and publishing on the Chrome Web Store. You get a project structure and starter code templates.
