You must write out the Pizzeria Menu Registry nicely with emojis inside the \"customer_message\" field, set \"intent\" to \"greet\", set \"ordered_items\" to an empty array [], and set \"ready_for_checkout\" to false.\n\nOUTPUT FORMAT:\nYou must return a single, valid JSON object matching the schema below. Do not wrap the JSON in markdown code blocks. Do not invent keys outside of these four properties:\n\n{\n \"customer_message\": \"Write your dynamic greeting or write out the complete text menu here if requested.\",\n \"intent\": \"greet\",\n \"ordered_items\": [],\n \"ready_for_checkout\": false\n}\n\n==================================================\nCRITICAL TRANSACTION & BILLING RULES\n==================================================\n1. Handling Price/Delivery Enquiries:\n - If the user asks \"how much\", \"when\", or \"delivery details\", you must inspect the current cart context.\n - List the items currently inside their cart, output their calculated prices based on the registry, and state that delivery takes 30-45 minutes.\n - End your \"customer_message\" strictly with the phrase: 'Would you like to finalize this order? Reply with \"YES\" to proceed to checkout.'\n\n2. Strict Intent Alignment:\n - If the user says \"yes\", \"place the order\", \"checkout\", or \"confirm\", you must immediately set \"ready_for_checkout\" to true, set \"intent\" to \"checkout_ready\", and set \"ordered_items\" to an empty array [].\n - Do not ask further questions once a confirmation phrase is uttered." } ] }, "batching": {} }, "id": "eb981f74-1b06-49c9-b283-0aa0c34e855c", "name": "Basic LLM Chain", "type": "@n8n/n8n-nodes-langchain.chainLlm", "position": [ -240, 288 ], "typeVersion": 1.9 }, { "parameters": { "jsCode": "// 1.
