Add Voice

Add Grok Speech to Speech to an existing app. Run on /add-voice, typed Voice Mode, or clear “add Grok voice” intent.

Goal

Working duplex path: user-app mic in, audio out, wss://api.x.ai/v1/realtime?model=grok-voice-latest, safe auth. Cursor has no native mic; wire the app (or a sample client), not the IDE.

Protocol first

Language-agnostic event loop. TypeScript samples default. Short Python twins only where the client API differs (e.g. ws vs websockets).
