Your job is to manage the user's calendar by **booking**, **checking**, **updating**, and **canceling** appointments. You must follow the correct logic based on the `category` value in the request.\n\n---\n\n## \ud83d\udee0\ufe0f Available Tools\n\n* **Book Appointment**: Use **only** when the category is `new_booking` and the time is confirmed to be available.\n* **Get Appointments**: Use when the category is `check_availability`, or when checking availability before any other action.\n* **Cancel Appointment**: Use **only** when the category is `cancel_appointment` and after retrieving the appointment ID using **Get Appointments**.\n* **Update Appointment**: Use **only** when the category is `update_appointment` and after retrieving the appointment ID using **Get Appointments**.\n\n---\n\n## \u2705 Rules to Follow\n\n* Always turn the user's request into an actionable command.\n\n* Only act based on the `category` value:\n\n * If `category` is `check_availability`: **Use only Get Appointments. Do not book.**\n * If `category` is `new_booking`: **Use Get Appointments to check**, then proceed with **Book Appointment** only if time is available.\n * If `category` is `cancel_appointment`: **Use Get Appointments**, then use **Cancel Appointment** with the correct ID.\n * If `category` is `update_appointment`: **Use Get Appointments**, then use **Update Appointment** with the correct ID.\n\n* There can only be one appointment per one-hour time slot.\n\n* If the requested time is already booked, respond with: `\"Not Available\"` and suggest **only 2 alternative one-hour time slots** on the same day. Do not book until the client confirms.\n\n* Use the summary: `\"Consultation Appointment\"` for every booking.\n\n* Appointments always involve one participant.\n\n* If no duration is provided, assume the appointment lasts exactly **one hour**.\n\n* Never assume availability \u2014 always confirm it first using **Get Appointments**.\n\n---\n\n* Convert vague time frames like \"tomorrow at 4 PM\" into precise ISO 8601 timestamps using `{{ $now }}` as reference.\n\n---\n\n## \ud83d\udd01 Example Flow Summary\n\n1. Receive a request, e.g., *\"Book me an appointment tomorrow at 4 PM\"*\n2. Check the `category` field:\n\n * If `category` is `check_availability`: Use **Get Appointments** with the provided day and time. Do not proceed with booking.\n * If `category` is `new_booking`: Use **Get Appointments** to verify availability.\n\n * If the time is available: Proceed with **Book Appointment**.\n * If the time is not available: Respond with \"Not Available\" and suggest 2 alternative time slots.\n * Wait for confirmation before proceeding with the booking.\n * If `category` is `cancel_appointment`: Use **Get Appointments** to retrieve the appointment ID, then call **Cancel Appointment**.\n * If `category` is `update_appointment`: Use **Get Appointments** to retrieve the appointment ID, then call **Update Appointment** with the new time and date.\n\n---\n\n### \ud83e\ude9c Keep It Clean\n\n* Never guess or make assumptions.\n* Follow tool logic strictly by category.\n* Do not skip required steps or bypass availability checks.\n* Do not return any links or url\n\n---\n\n## \ud83d\udd52 Date & Time Context\n\n* Treat the following as the **current date and time: `{{ $now }}`**\n* One appointment per hour only.\n" } }, "type": "@n8n/n8n-nodes-langchain.agent", "typeVersion": 1.8, "position": [ -20, 100 ], "id": "0f6fe2b8-0fc1-4520-b94e-5092fa99b1d2", "name": "Calendar Agent" }, { "parameters": { "calendar": { "__rl": true, "value": "e65463fc466fd521dc1ecc1964b4d6dbac77710e2a00f0a73b597f41477d9def@group.calendar.google.com", "mode": "list", "cachedResultName": "AI Agent" }, "start": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Start', ``, 'string') }}", "end": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('End', ``, 'string') }}", "additionalFields": { "attendees": [ "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Attendees', ``, 'string') }}" ], "summary": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Summary', ``, 'string') }}" } }, "type": "n8n-nodes-base.googleCalendarTool", "typeVersion": 1.3, "position": [ 20, 320 ], "id": "da016177-45dd-4c95-98a4-4578a1e08b40", "name": "Book Appointment", "credentials": { "googleCalendarOAuth2Api": { "name": "" } } }, { "parameters": { "operation": "update", "calendar": { "__rl": true, "value": "e65463fc466fd521dc1ecc1964b4d6dbac77710e2a00f0a73b597f41477d9def@group.calendar.google.com", "mode": "list", "cachedResultName": "AI Agent" }, "eventId": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Event_ID', ``, 'string') }}", "updateFields": { "end": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('End', ``, 'string') }}", "start": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Start', ``, 'string') }}" } }, "type": "n8n-nodes-base.googleCalendarTool", "typeVersion": 1.3, "position": [ 200, 320 ], "id": "bd5549bf-c1ce-454a-9643-43d1af20e782", "name": "Update Appointment", "credentials": { "googleCalendarOAuth2Api": { "name": "" } } }, { "parameters": { "operation": "getAll", "calendar": { "__rl": true, "value": "e65463fc466fd521dc1ecc1964b4d6dbac77710e2a00f0a73b597f41477d9def@group.calendar.google.com", "mode": "list", "cachedResultName": "AI Agent" }, "returnAll": true, "timeMax": "={{ $now.plus({ week: 24 }) }}", "options": { "fields": "items(id,summary,start,end,attendees)" } }, "type": "n8n-nodes-base.googleCalendarTool", "typeVersion": 1.3, "position": [ -140, 320 ], "id": "3e1adcad-39ae-41da-b52b-f9a8e52715ee", "name": "Get Appointments", "credentials": { "googleCalendarOAuth2Api": { "name": "" } } }, { "parameters": { "operation": "delete", "calendar": { "__rl": true, "value": "e65463fc466fd521dc1ecc1964b4d6dbac77710e2a00f0a73b597f41477d9def@group.calendar.google.com", "mode": "list", "cachedResultName": "AI Agent" }, "eventId": "={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Event_ID', ``, 'string') }}", "options": {} }, "type": "n8n-nodes-base.googleCalendarTool", "typeVersion": 1.3, "position": [ 380, 320 ], "id": "3aaae3af-4c21-4775-94c4-59a2a5594b44", "name": "Cancel Appointment", "credentials": { "googleCalendarOAuth2Api": { "name": "" } } }, { "parameters": { "httpMethod": "POST", "path": "smartpulse-agency-receptionist", "responseMode": "responseNode", "options": {} }, "type": "n8n-nodes-base.webhook", "typeVersion": 2, "position": [ -700, 100 ], "id": "c22ac278-00cb-472b-9103-d658dd3b2754", "name": "Webhook" }, { "parameters": { "promptType": "define", "text": "=details: {{ JSON.stringify($json.body.message.toolCalls[0].function.arguments) }}", "options": { "systemMessage": "=You are a data-cleaning assistant for an AI scheduling agent.\n\nYour task is to process incoming JSON objects and return a cleaned version with the following:\n\n### \u2705 Requirements\n\n1. **Correct the email**:\n -
