Imagine getting an email from a customer asking about your store hours. Instead of checking your inbox every minute, an AI steps in. It reads the message, pulls the answer from your files, and sends a quick reply—all on its own. That’s the magic of an AI agent. You’ve likely chatted with tools like ChatGPT, which spit out answers but stop there. An AI agent goes further. It links to your apps, like email or Slack, to handle real tasks.
Think of a standard chatbot as a helpful desk clerk who talks but doesn’t file papers. An AI agent, though, grabs the files, stamps them, and drops them in the right spot. It connects to tools such as email for replies, spreadsheets for updates, or Slack for alerts. This setup lets it act without you lifting a finger. The real edge comes from its ability to start tasks solo. Based on rules you set, it spots issues and jumps in, saving you hours on routine stuff.
Now, picture building this without coding. Enter Make, a simple drag-and-drop tool for linking apps. You sketch flows visually, and the agent thinks through the rest. No need for tech headaches. In this guide, we’ll walk through creating one for customer support at a pretend cookie shop. It handles easy questions alone and flags big ones for your team. By the end, you’ll know how to craft your own for any job.

Section 1: Initial Setup—Creating and Configuring Your AI Brain
Start by logging into Make. You’ll land on the main view. Click “AI Agents beta” under My Team, then hit “Create Agent.” This opens the setup screen.
Step 1: Establishing the AI Connection and Model Selection
First, set up the AI link. Click “Create a Connection” at the top. Pick a provider—Make’s own works best for quick starts, no extra fuss. Save it with the default name. Providers vary: some shine at deep thinking, others at speed or low cost. Choose based on your needs, like support chats that need smart replies.
Next, name your agent. Call it something clear, like “KCC Support Agent” for the cookie company. Pick a model from the list. Go with “large” for handling tricky customer talks—it thinks deeper than basic ones. This choice fits most support roles, where questions mix simple facts with nuance.
Step 2: Crafting the System Prompt and Guardrails
The system prompt shapes your agent’s job. It’s like giving it a job description. Type in what it should do: handle emails for the Kevin Cookie Company. For common questions, draft friendly replies. For tough ones—like bulk orders or refunds—send a summary to Slack with a suggested answer. Add rules at the end, such as “Never give refunds or discounts alone.” This keeps things safe.
Why does this matter? A strong prompt guides decisions. Without it, the agent might guess wrong. Test it early to tweak. Save everything in the bottom corner. Now you’re in the main view, ready to add smarts.
Step 3: Injecting Context with External Knowledge Bases (FAQs)
Agents need background to shine. Click “Add” under context on the left. Upload a file like your FAQ doc. For the cookie shop, it lists hours, nut info, delivery options—top questions customers ask.
Drag the file in and hit upload. It loads fast. Skip advanced bits like MCP for now; that’s for linking extra services later. Test by asking, “What are the store hours?” The agent pulls from the FAQ and replies nicely: “We’re open Monday to Friday, 9 AM to 5 PM.” Customers will eat this up—pun intended.
Save in the top corner. Your agent now knows key facts. This step turns a blank slate into a knowledgeable helper.
Section 2: Building the Core Workflow—Triggering the Agent Scenario
With the brain set, build the flow. Click “Scenarios” on the left. Hit “Create a new scenario” in the top right. Start blank—this is your automation chain.
Designing the Trigger: Automating Based on Incoming Data
A scenario runs steps in order, like a recipe. The trigger kicks it off. Click the big plus in the center. Search for your email app, say Outlook. Pick “Watch for new email messages” from the modules.
Connect your account if new. Set it to check the inbox only. Add filters if needed, like from certain senders. Save and set to start “from now on.” Now, every fresh email fires the workflow. No more manual checks— the agent wakes up automatically.
This setup scales easy. For other triggers, swap email for form submits or app alerts. It keeps things responsive.
Integrating the Agent Module into the Workflow
Add the next step with another plus. Search “Make AI Agents.” Choose “Run an agent.” Select your KCC one from the dropdown.
Skip tools for now—we’ll add them later. Scroll to messages at the bottom. These feed info to the agent. Click “Add Item” for the first message. Map email bits: ID, subject, body, sender. Use the left panel to pull data from the trigger.
Add a second message for instructions: “Format the reply in HTML.” Include simple tags for bold or lists. This ensures clean outputs. Save the module. Name the scenario “Respond to Customer Email” in the top left.
Mapping Input Data for Agent Comprehension
Why map carefully? The agent needs full context to decide right. Include the message ID to tie replies back. Body and subject give the meat. Sender helps personalize.
In practice, test mappings. If body misses attachments, add them. For HTML, keep tags basic—no fancy code. Set the scenario to “On Demand” so it runs per email, not on a timer. Activate it and save. Your workflow now thinks on incoming mail.
This bridge from trigger to agent is key. It turns raw data into smart action.
Section 3: Equipping the Agent with Actionable Skills (Tools)
Tools let your agent do more than chat. They’re like add-ons for real work. Each is a mini-scenario the agent calls as needed.
Understanding Tools: Giving the Agent Arms and Legs
On its own, the agent reads and writes text. Tools add power: send emails, update sheets, ping teams. Build them as separate scenarios. The agent picks when to use them based on prompts.
Start simple. We’ll make two: one for replies, one for Slack alerts. This extends the agent from thinker to doer. No code—just connect apps.
Building Tool 1: The Email Reply Functionality
Create a new scenario for the reply tool. Click the bottom icon for inputs. Add “email message ID” first. Then “email reply text” from the agent.
Save inputs. Hit plus and search Outlook. Pick “Reply to a message.” Map ID to the input variable. Map reply text to the body field.
Connect if needed. Save the module. Name it “Email Reply Tool.” Set to “On Demand,” activate, and save. Now the agent can hit reply with custom text, linked to the original.
Test it solo: feed sample data and watch it send. This tool closes the loop on easy queries.
Building Tool 2: Escalation and Team Notification via Slack
New scenario again. Add inputs: customer email, subject, body. Save them.
Plus icon, search Slack. Choose “Create a message.” Connect your workspace. Pick the channel—say, “Customer Escalations.”
Map inputs to the text: Start with sender, add subject, paste body. Use the variable picker. This posts full details for quick team review.
Name it “Post Escalation to Slack.” Set “On Demand,” activate, save. Your agent now flags big asks without inbox dives.
Section 4: Connecting Tools to the Agent’s Decision Matrix
Tools built? Link them back. Go to the main scenario and edit the agent module.
Linking Scenarios: Granting Agent Access to New Tools
Click “Add Tools” in the agent settings. Select “Email Reply Tool” from the list. Add a short description: “Sends a response back to the customer, tied to the original message, using the reply text generated by the agent.”
Hit add. Repeat for Slack: “Posts to Slack, shares customer email details in a Slack channel, so the team stays updated on new messages or escalations.” Add and save the module.
This wires the brain to the hands. The agent chooses tools based on email type—FAQ match? Reply. Bulk order? Slack it.
Describing Tool Functionality for Agent Utilization
Clear descriptions guide choices. Vague ones lead to wrong calls. Keep them action-focused: what it does, when to use. Tie to your prompt, like escalating complex issues.
Update if needed. Test: The agent should pick reply for hours questions, Slack for custom logos.
Final Activation and Testing the Autonomous Loop
Save the scenario. Run once on a test email: “What are your hours?” Check inbox—auto reply with FAQ info. Good.
Now a tough one: “Ship 1,000 cookies by Friday with logos.” Run it. Slack lights up with details. Team sees sender, subject, body—ready to jump in.
All scenarios active? You’re live. Simple mails get handled; hard ones get help. This loop runs 24/7.
Conclusion: Visualizing and Scaling Your AI Infrastructure
Jump to the Make Grid on the left. It maps your whole setup. See the email trigger flow to the agent, then split: reply path or Slack path. Arrows show links—clear as a flowchart.
Spot shared bits, like the agent in multiple flows. Add more, say for refunds or surveys, and it updates. No mess; everything connects.
You just built your first AI agent. It tackles routine support, flags the rest, all without code. Key wins: auto-replies save time, escalations keep teams sharp, visuals track it all. Next, try new triggers or tools—like sheet logs for orders. Grab a free Make Pro month to start. Build yours today and watch efficiency soar.
