Your function is to process the complete state of a small town and determine the next logical, simultaneous action for EVERY agent within it. You will receive the entire world state as a JSON object and must return a JSON object describing each agent's subsequent action.\n\n# Core Logic & Persona Adherence\n1. **Simultaneity:** You are calculating a single \"tick\" of the clock. All agent actions should be considered as happening at the same time.\n2. **Persona-Driven Actions:** An agent's action MUST be consistent with their defined 'persona'. A baker will think about bread, a librarian about books, a mysterious stranger about observing others.\n3. **Environmental Interaction:** Agents should react to their location, the objects within it, and other agents present. If two people are in the same location, they might interact. An agent in a library should perform library-appropriate actions.\n4. **Temporal Awareness:** Actions must be logical for the given 'time_of_day'. People work during the day, socialize in the evening, and sleep at night.\n5. **Memory & Continuity:** Agents' new actions should logically follow from their previous action and memories. Avoid jarring, out-of-character changes.\n\n# Input Format\nYou will be given a JSON object representing the current 'TownState':\n{\n \"time_of_day\": \"string\",\n \"locations\": [{\"name\": \"string\", \"description\": \"string\", \"objects\": [\"string\"]}],\n \"agents\": [{\"name\": \"string\", \"persona\": \"string\", \"location\": \"string\", \"action\": \"string\", \"memories\": [\"string\"]}]\n}\n\n# Output Specification\nThis is the most critical rule. Your entire response MUST be a single, minified JSON object.\n- The root key must be \"agent_updates\".\n- The value must be an array of objects, one for each agent.\n- Each object must contain:\n - \\`agent_name\\`: The name of the agent being updated.\n - \\`new_location\\`: The agent's new location (can be the same as the old one).\n - \\`new_action\\`: A concise, present-tense description of the agent's new action.\n\n## Example Output:\n{\n \"agent_updates\": [\n {\n \"agent_name\": \"Elara\",\n \"new_location\": \"Bakery\",\n \"new_action\": \"Kneading dough for the morning batch of sourdough bread.\"\n },\n {\n \"agent_name\": \"Liam\",\n \"new_location\": \"Town Square\",\n \"new_action\": \"Reading a worn-out book on a bench, occasionally glancing at passersby.\"\n }\n ]\n}\n`;\n\n// --- IN-MEMORY STATE ---\nlet townState: TownState | null = null;\n\nconst getInitialTownState = (): TownState => ({\n time_of_day: \"8:00 AM\",\n locations: [\n {\n name: \"Town Square\",\n description: \"A central plaza with a fountain and benches.\",\n objects: [\"fountain\", \"bench\", \"old oak tree\"],\n },\n {\n name: \"The Rolling Pin Bakery\",\n description: \"A cozy bakery filled with the scent of fresh bread.\",\n objects: [\"oven\", \"display case\", \"flour sacks\"],\n },\n {\n name: \"The Quiet Shelf Library\",\n description: \"A dusty library with towering shelves of old books.\",\n objects: [\"card catalog\", \"reading desk\", \"rare manuscripts section\"],\n },\n ],\n agents: [\n {\n name: \"Elara\",\n persona: \"The town's diligent and cheerful baker, always focused on her craft.\",\n location: \"The Rolling Pin Bakery\",\n action: \"Unlocking the front door of the bakery.\",\n memories: [\"Woke up early to prepare the ovens.\"],\n },\n {\n name: \"Liam\",\n persona: \"The town's reclusive librarian and historian, protective of his books.\",\n location: \"The Quiet Shelf Library\",\n action: \"Organizing returned books on a cart.\",\n memories: [\"Found a mis-shelved book on local myths yesterday.\"],\n },\n {\n name: \"Kael\",\n persona: \"A mysterious stranger who just arrived in town, keenly observing everything.\",\n location: \"Town Square\",\n action: \"Watching the town slowly come to life from the shade of the old oak tree.\",\n memories: [\"Arrived on the midnight coach with a single, heavy bag.\"],\n },\n ],\n});\n\n// --- HONO APPLICATION SETUP ---\nconst app = new Hono();\n\n// --- API ROUTES ---\n\n// Simple frontend to interact with the API\napp.get(\"/\", (c: Context) => {\n return c.html(`\n \n \n \n \n \n Town Simulator\n \n \n \n
