How to use wintermolt Skill

Install or run

git clone https://github.com/lupin4/wintermolt.git
cd wintermolt
zig build -Doptimize=ReleaseSmall
./zig-out/bin/wintermolt

Client configuration

Built with AppKit `NSStatusBar` — no Electron, no web views. Communicates with the Zig backend via JSON lines over stdin/stdout, same battle-tested IPC pattern used by the chat and web bridges.

### Canvas / A2UI

The AI can render rich UI surfaces — tables, layouts, code blocks — directly in your terminal using box-drawing characters, or in the browser via the web bridge.
