KpopDemonCoders is a macOS-native multi-agent AI desktop companion where bugs are "demons" and fixing code is "exorcism."

Problem: Solo developers debug alone without feedback, increasing cognitive load and burnout. We turn silent debugging into dialogue — a pixel-art Grim Reaper watches your screen and speaks when it spots issues.

Architecture (Swift 6.2, zero deps, MARL-inspired):

• VisionAgent: Gemini 3 Flash analyzes active window every 5s via generateContent with responseSchema and thinkingConfig: minimal

• Mediator + AdaptiveScheduler: Gates speech and learns user patterns — ignore it, it talks less; engage, more

• GeminiLiveClient: Affective voice via Gemini 2.5 Flash Native Audio WebSocket with enableAffectiveDialog, sessionResumption, contextWindowCompression

• Google Search Grounding for real-time doc lookup
Not a chatbot — a proactive AI agent that sees, reasons, and speaks in real time.
