# Mode Maker: AI creating AI

Because every feature in Pneuma is abstracted behind the `ModeProtocol`, we built a Mode to create other Modes.

### 1. Fork & Scaffold

Start the `mode-maker` mode. Tell Claude you want a "Kanban Board Mode". It automatically forks a basic template and scaffolds your React files.

### 2. Play-test Instantly

Hit "Play". Pneuma spins up a nested server running your newly coded Viewer. You can test your Kanban layout side-by-side while Claude codes it.

### 3. Publish to Network

Once complete, run `pneuma mode publish`. Your mode is uploaded to the R2 registry, immediately available in the global Launcher Marketplace.
