Initial System Design & LangGraph Schema

Design the overall architecture for the multi-agent AI slop detection system. Define the roles of at least three distinct agents (e.g., Content Ingester, AI Detector, Moderation Decision Maker). Outline their responsibilities, communication protocols, and the LangGraph schema (nodes, edges, state transitions) that orchestrates their collaboration. Specifically, describe how extended thinking will be initiated for complex cases and where MCP integration will occur.
