n8n AI Agent Workflow: Multi-Agent HR Department with OpenAI & GPT-41 Mini

This n8n workflow demonstrates a foundational multi-agent system designed to simulate an HR department using AI agents. It leverages LangChain nodes within n8n to orchestrate communication and task execution between different AI personas.

What it does

This workflow sets up the core components for an AI-driven HR department, specifically:

Listens for Chat Messages: It acts as a trigger, initiating the workflow whenever a new chat message is received. This is the entry point for user interaction with the HR system.
Initializes an AI Agent: A primary AI agent is configured, likely acting as the central coordinator or a specific HR role (e.g., HR Assistant). This agent will interpret the incoming chat messages and decide on the next steps.
Defines a Chat Model: An OpenAI Chat Model is specified, which will be used by the AI agents for understanding natural language, generating responses, and performing reasoning.
Includes a "Think" Tool: A "Think" tool is provided, which allows the AI agent to perform internal reasoning, planning, or complex logical operations before performing an action or responding. This is crucial for multi-step tasks.
Integrates an AI Agent Tool: Another AI agent is included as a tool. This signifies the multi-agent aspect, where one agent can delegate tasks or consult with another specialized agent (e.g., an HR Assistant agent might use a "Recruitment Agent Tool" to handle hiring-related queries).

Prerequisites/Requirements

n8n Instance: A running instance of n8n.
OpenAI API Key: An API key for OpenAI, configured as a credential in n8n, to power the OpenAI Chat Model.

Setup/Usage

Import the workflow: Import the provided JSON into your n8n instance.
Configure OpenAI Credentials: Ensure you have an OpenAI credential set up in n8n. If not, create one and select it in the OpenAI Chat Model node.
Activate the Workflow: Toggle the workflow to "Active" to start listening for chat messages.
Interact: Send chat messages to the configured Chat Trigger (e.g., via a connected chat service like Slack or Telegram, if the trigger is further configured). The AI agent will process these messages and potentially use its tools to respond.

Note: This workflow provides the foundational structure. To create a "complete HR department" as suggested by the directory name, you would need to:

Further configure the AI Agent nodes with specific prompts, roles, and instructions.
Add more specialized AI Agent Tool nodes for different HR functions (e.g., "Payroll Agent Tool", "Onboarding Agent Tool").
Integrate external services (e.g., Google Sheets for employee data, email for sending notifications, HRIS systems via API) using n8n's vast array of nodes, which would then be callable by the AI agents as tools.

Track meal nutrition from meal photos with LINE, Google Gemini and Google Sheets

AI Meal Nutrition Tracker with LINE and Google Sheets Who's it for This workflow is designed for health-conscious individuals, fitness enthusiasts, and anyone who wants to track their daily food intake without manual calorie counting. It is best suited for users who want a simple, AI-powered meal logging system that analyzes food photos one at a time and provides instant nutritional feedback via LINE. What it does This workflow processes a single meal photo sent via LINE, analyzes it using Google Gemini AI to identify foods and estimate nutritional content, and stores the data in Google Sheets for tracking. The workflow focuses on simplicity and encouragement: it receives a meal image, performs AI-based food recognition, estimates calories and macronutrients, calculates a health score, provides personalized advice, and replies with a detailed nutritional breakdown on LINE. How it works A single meal photo is sent to the LINE bot. The workflow is triggered via a LINE webhook. The image file is downloaded and sent to Google Gemini AI for food analysis. The AI identifies foods and estimates nutritional values (calories, protein, carbs, fat, fiber). A health score (1-10) is calculated with personalized improvement tips. The data is appended to Google Sheets for meal history tracking. The image is uploaded to Google Drive for reference. A formatted nutritional report with advice is sent back as a LINE reply. This workflow is intentionally designed to handle one image per execution. Requirements To use this workflow, you will need: A LINE Messaging API account A Google Gemini API key A Google account with access to Google Sheets and Google Drive A Google Sheets document with the following column names: Date Time Meal Type Food Items Calories Protein (g) Carbs (g) Fat (g) Fiber (g) Health Score Advice Image URL Important limitations This workflow does not support multiple images sent in a single message. Sending images in quick succession may trigger multiple executions and lead to unexpected results. Only the first image in an event payload is processed. Nutritional values are AI estimates based on visual analysis and typical serving sizes. Accuracy depends on image quality, lighting, and food visibility. This tool should not replace professional dietary advice. These limitations are intentional to keep the workflow simple and easy to understand. How to set up Create a LINE Messaging API channel and obtain a Channel Access Token. Generate a Google Gemini API key. Update the Config node with your LINE token, Google Sheets ID, Google Drive folder ID, and daily calorie goal. Configure credentials for LINE, Google Gemini, Google Sheets, and Google Drive. Register the n8n webhook URL in your LINE channel settings. Activate the workflow in n8n and test it with a single meal photo. How to customize Modify the AI prompt in the "Analyze Meal with AI" node to support different languages or dietary frameworks (keto, vegan, etc.). Adjust the daily calorie goal in the Config node to match individual needs. Add additional nutritional fields such as sodium, sugar, or vitamins. Replace Google Sheets with a fitness app API or database. Integrate with other services to send daily/weekly nutrition summaries. --- Note: This workflow was tested using real meal photos sent individually via the LINE Messaging API. Nutritional estimates are approximations and may vary from actual values. For accurate dietary tracking, consult a registered dietitian.
