## Install

```bash
npx skills add https://github.com/emilkowalski/skills --skill prototype
```

## In the author's words

Build multiple genuinely different versions of a UI piece you describe, rendered behind a visual picker so you can flip through them live and promote the one that feels right. Only runs when explicitly invoked; it does not trigger on its own.
