Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install winui-3-desktop-app-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 classifies the request (setup, bootstrap, design, review or troubleshooting), then follows the setup method before proposing structure, controls and navigation. You get a verified WinUI 3 foundation and targeted advice.
