How to Tell an AI Agent What to Do: Write a Playbook in Your Voice

August 26, 2026
Start here: spend one hour writing down your openers, your questions, and the words you'd never use

Let me tell you where folks go wrong with AI, because I went wrong there myself first. The agent is not the hard part. Setting up a tool that can send a text or make a call takes an afternoon now. The hard part, the part that actually decides whether this thing helps you or embarrasses you in front of a seller, is what you tell it to do. My thinking is that an AI agent is a brand-new hire who is fast, tireless, and completely literal. It will do exactly what you said, at three in the morning, ten thousand times in a row, whether what you said was smart or not.

So the whole game is the playbook. The instructions. And most people write those instructions the way they'd fire off a text to a buddy, three vague sentences, and then they're surprised when the agent sounds like a robot reading a brochure. I've written a lot of these now, for following up with seller leads and for a dozen other little jobs, and I want to walk you through how I actually do it. Not the theory. The steps. Because when you write the playbook right, the agent stops sounding like a machine and starts sounding like you, and that difference is worth real money.

Start by writing down what you already say

Before you type a single instruction into any AI tool, do something that feels almost too simple. Write down what you actually say when you do the job yourself.

Here's what I mean. If you want an agent to follow up with a seller who filled out your form, don't start by describing an AI. Start by remembering the last five times you made that call. What did you open with? I open warm. "Hey, this is Tim, you reached out about your place over off 1187 in Crowley, is now an okay time?" What questions do you always ask? What do you say when they tell you they're just looking for a number? What do you never say, because it makes people put their guard up? Write all of it down, in your own words, exactly the way it comes out of your mouth.

This step is the one everybody skips, and it's the one that matters most. The reason your agent sounds like a robot is that you handed it robot instructions. You wrote "follow up professionally and try to book an appointment," and it gave you back exactly that, a professional-sounding nothing. But if you hand it three real openers you actually use, the words you'd say to somebody nervous about losing their house, the little acknowledgment you make before you ever ask for anything, now it has your voice to copy. Ultimately the agent can only mirror what you give it. Give it a brochure, you get a brochure. Give it you, you get something close to you.

I keep this in a plain document. Not fancy. Just a running page of "here's what I say, here's what I ask, here's what I never say." My people are the folks who have to struggle to put this together, and I promise you this part costs nothing but an honest hour. It's the cheapest, highest-return hour you'll spend on any of this.

Turn what you say into a playbook the agent can follow

Once you've got your own words on paper, you shape them into instructions. I think about it in four plain pieces, and I write each one out for the agent the same way I'd brief a new team member on their first day.

First, the job. One or two sentences on what this agent is for and, just as important, what it is not for. "You follow up with sellers who asked for a cash offer. You are not the person who negotiates price. When price comes up, you set the appointment and hand it to me."

Second, the voice. This is where you paste in the real openers and phrases you wrote down in step one. I literally tell the agent, "talk like this," and give it examples. I tell it what to avoid too. No pressure words. No fake urgency. Acknowledge the person before you ask for anything.

Third, the steps. Walk the conversation in order, the way it really goes. Open, ask if now's a good time, listen, acknowledge what they said, ask the two or three questions you always ask, and aim for one thing, the next step. Different situations go different directions, so I write the branches out. If they're ready to talk, do this. If they're cold, do that. If they ask something you didn't plan for, don't guess.

Fourth, and this is the one I'd tattoo on the wall if I could, the escape hatch. Tell the agent exactly when to stop and get you. I call it the two-output rule. Every single interaction ends one of two ways. Either the agent handles it cleanly inside the lines you drew, or it hands the situation to a human, meaning me. There is no third option where it improvises on something it wasn't taught. "If you're not sure, if they're upset, if they ask about anything involving money or legal or the actual offer, you stop and you flag it for Tim." That one instruction is what lets you sleep at night. It's the seatbelt.

That's the whole shape of it. The job, the voice, the steps, and the escape hatch. You can write your first real playbook in an evening.

Test it small, fix what it gets wrong, then let it run

The playbook has four parts: the job, the voice, the steps, and the escape hatch

Now, here's where I have to be straight with you, because I've watched people do this part wrong and get hurt. Different tools behave differently, and none of them are perfect out of the gate, so you do not turn this loose on your live leads on day one. You test it small.

The way I do it is I run the agent against myself first. I pretend to be the seller. I give it the easy version, then I give it the cranky version, then I give it the curveball, the question I didn't write a branch for, just to see what it does. And I'm watching for one thing above all. When it hits something it wasn't taught, does it stop and flag me like I told it to, or does it start making things up? If it makes something up, I don't blame the agent. I go back to the playbook, because that's on me. I didn't draw the line clearly enough. So I add the missing branch, or I tighten the escape hatch, and I run it again.

You do this maybe a dozen times and something clicks. The agent starts sounding like the document you wrote, which is to say it starts sounding like you, and it starts flagging the right things instead of winging them. That's when I let it touch a small slice of real leads, watch it close for a week, read what it actually said to people, and keep tuning. One honest word of caution before you point any agent at real people: automated calls and texts to consumers are regulated, so make sure you've got the consent and you're following the telemarketing rules where you operate before you turn it loose. And don't rush the timing either, because knowing when you're ready to hand work to a machine matters as much as knowing how. At the end of the day this is not "set it and forget it." It's "set it, watch it, fix it, then trust it a little more each week." The trust is earned, same as it would be with a person.

And that's really the honest picture of how you tell an AI agent what to do. You write down your own words first. You shape them into a job, a voice, a set of steps, and an escape hatch. Then you test it against yourself until it sounds like you and stops guessing, and only then does it go anywhere near the people you're trying to serve. None of that requires you to be technical. It requires you to be clear about what you already know how to do, which you are, because you've been doing the job. The agent is just there to do it while you sleep. I don't know if that answers every question you've got about this, but it's the part that took me the longest to learn, so it's the part I most wanted to hand you.
