Because every feature in Pneuma is abstracted behind the ModeProtocol, we built a Mode to create other
Modes.
Start the mode-maker mode. Tell Claude you want a "Kanban Board Mode". It automatically forks a
basic template and scaffolds your React files.
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.
Once complete, run pneuma mode publish. Your mode is uploaded to the R2 registry, immediately
available in the global Launcher Marketplace.
