The AI is strictly programmed to follow rules for *Doppelgangers* (subtle lying) vs. Real Humans (truthful according to lore).\n5. **Strict JSON Delivery:** The system ensures responses are returned to the game client in pure JSON format, ready to be parsed by the gameplay scripts.\n\n### **Setup steps**\n1. **API Keys:** Enter your **Google Gemini API Key** in the credentials of the LLM and Embeddings nodes.\n2. **Knowledge Base:** Authenticate **Google Drive OAuth2** and ensure the lore PDF File ID is correct and accessible.\n3. **Webhook Setup:** Copy the n8n Webhook URL (Production/Test) and integrate it into the HTTP Request script in your game engine.\n4. **Data Ingestion:** Click \"Execute workflow\" on the Manual Trigger (bottom left) ONCE to download the PDF and load it into the Vector Store before starting to play.\n\n### **Requirements**\n- n8n instance (Local/Cloud).\n- Google Gemini API Key.\n- Google Drive API credentials (for RAG document ingestion)."

"content": "### **Section 2: Main Game API & Logic Core**\n\nThis central section acts as the primary API endpoint for the game. It handles all incoming requests, routes them to the correct AI agent, and returns structured data to the game engine.\n\n### **How it works**\n1. **Webhook & Switch:** The **Webhook** receives the JSON payload from the game. The **Switch** node then routes the flow based on the `action` parameter (`briefing`, `init`, or `chat`).\n2. **Specialized Agents:** \n - **DayClue creator:** Generates daily intel (weather, blocked routes, discounts) based on the player's morale stat.\n - **npc creator:** Uses RNG to spawn an NPC profile (Real Human or Doppelganger) and generates their opening dialogue.\n - **Chat Generator:** Handles the ongoing interrogation, following strict rules to either lie subtly (Doppelganger) or tell the exact truth (Human).\n3. **Context & LLM:** Powered by the **Google Gemini Chat Model**, utilizing **Simple Memory** to retain the interrogation context across multiple turns.\n4. **Respond to Webhook:** Ensures all AI outputs are cleanly formatted into pure JSON before being sent back to the game client."

The agents in Section 2 use this tool to fact-check locations, prices, and rules before answering player questions.\n2. **Standalone Chat Testing:** The **When chat message received** trigger allows developers to interact with the AI directly via a chat interface, bypassing the game engine.\n3. **AI Agent (Testing Bot):** A dedicated agent configured to test the functionality of the `Database_Bunker` tool. It validates whether the AI can successfully retrieve and format data from the ingested lore document.\n4. **Window Buffer Memory:** Keeps track of the chat history specifically for this standalone testing interface."
