Have the final say on an AI agent: validate, then delegate

An AI agent prepares the work, you decide what goes out. You will learn how to review its first sends, what signs show an agent is ready to work alone, and which tasks deserve to keep your signature, no matter what.

Have the final say on an AI agent: validate, then delegate
Key takeaways
  • The agent proposes, you validate: that's the rule for first sends.
  • Three successful validations open the door to automation, without forcing it.
  • An agent is ready when you no longer correct anything important.
  • Commitments, amounts, and sensitive topics keep your signature.
  • Returning to manual validation is always a good decision.

An AI agent that sends an email on your behalf speaks in your name. If it gets the tone, client, or amount wrong, it's your company that answers. So the right question isn't "is the agent intelligent?" but "when can I let it act alone, and for what exactly?". This course gives you a simple method to answer that, task by task, without jargon.

IWhat does it mean to "keep control" over an AI agent?

We call it human in the loop in English: a human stays in the loop. Concretely, the agent does all the preparation work (reading, sorting, writing), then stops before the action that matters: sending, publishing, responding to the client. You see the draft, you correct if needed, you click to send. The agent doesn't replace you in the decision. It brings it to you ready-made.

Definition
Human validation

The moment when a person reviews and approves what an agent has prepared before it is sent.

It's the main safeguard of an AI agent. It protects against substantive errors, tone missteps and sends to the wrong recipient. It also serves to teach the agent, and you, what is expected.

Take a real estate agency that entrusts an agent with responses to viewing requests. Monday morning, the agent has prepared eight responses. The manager reviews them in ten minutes, corrects one where the agent had suggested a time slot already taken, and validates the other seven. The work is done, and nothing was sent without her approval.

IIThe process at ABYS: from trial to automatic

On ABYS, this control is not a hidden option in a menu. It's part of the journey, in this order.

From first trial to automatic validation
  1. 1
    Dry run test

    The agent executes its mission for the first time without sending anything. You see exactly what it would have done: the emails drafted, the recipients chosen, the documents used. This is the time to spot a misunderstanding about the mission before it costs anything.

  2. 2
    First sends validated

    The agent works at the pace of your plan, for example once a day, but each send waits for your approval. You read, you correct if needed, you approve. Nothing goes out until you've clicked.

  3. 3
    Three validations

    After three validations, you can switch the agent to automatic validation. It's a possibility, not an obligation. You can stay in manual validation as long as you wish.

  4. 4
    Risks written down

    If you choose automatic, the risks of that choice are then written in black and white. You decide with full knowledge, not by a careless click.

  5. 5
    Regular monitoring

    On automatic, the agent sends alone. You keep an eye on what it does on a fixed date, and you stay ready to take back control as soon as doubt appears.

Three validations are a minimum to have a choice, not proof that the agent is ready. For a simple and repetitive task, they can be enough. For a varied task, wait until you've seen the agent face several different cases.

IIIHow do you know if an AI agent is ready to work alone?

The right criterion is not the number of days elapsed, it is what you correct. If you still rework the substance, the agent is not ready. If you only change a comma out of personal taste, it probably is. Go through the following list before switching.

IVWhat should never be automated

Some actions must keep your signature, even with a reliable agent. The rule is simple: if sending commits you, involves money or a delicate human situation, the agent prepares and you validate. It's not a question of trust in the tool. A single error at that point costs more than all the minutes of review time saved.

Automate or keep validation?
Automatic mode is reasonableValidation remains essential
Confirm receipt of a quote request
Send the quote itself, with its prices and deadlines
Politely remind about an overdue invoice
Announce a formal notice or penalty
Send the week's menu to the family
Respond to a client who complains or threatens
Follow up with a prospect who has not responded
Accept a discount or special condition
Sort received emails by subject
Write about a health issue, a bereavement or a conflict
Prepare an appointment list
Modify a contract, order, or payment

For a restaurant, letting the agent automatically confirm a standard reservation is not a problem. However, a response to a customer reporting food poisoning must go through the owner, word for word.

VWhat risks do you take by switching to automatic?

The risks are known and it's better to look them in the face. The agent can misunderstand an unusual request and answer it wrong. It can rely on a document that has become false, for example an old price list. It can repeat the same error on several sends before you see it. And an email sent can't be caught: you can apologize, but you can't erase it from the recipient's inbox.

These risks don't condemn automatic. They just say where to reserve it: for tasks where an error is easily fixed.

VIKeeping control once the agent is autonomous

Switching to automatic does not mean no longer looking. I recommend a regular meeting, for example Friday late morning, to review what the agent has sent during the week. Fifteen minutes is often enough. Look for sends that surprise you, customer responses that seem puzzled, cases the agent was unable to handle.

At the slightest doubt, switch back to manual validation while you understand. This step back is not a failure. A craftsperson adding a new service to their catalog has every interest in revalidating a few sends while verifying that the agent presents the new offering correctly. Starting small, on a single task, remains the best way to move forward.

The agent of a landscaping company has just obtained their third manual validation. What does ABYS allow at this point?

After three validations, you can switch the agent to automatic validation, without obligation. The risks of this choice are then clearly spelled out.

?Questions we're asked

What is human in the loop in AI?

It's the principle that a human stays in the decision loop. The AI agent prepares the work, but a person reviews and approves before any important action, like sending an email. This limits errors, keeps responsibility where it belongs, and lets you verify that the agent understood what you expected.

Can you let an AI send emails all by itself?

Yes, for simple tasks where an error is easily fixed, like a receipt confirmation or a polite follow-up. Start by validating the first sends by hand, check that the agent handles difficult cases, then decide. Sends that commit you, that involve money or a sensitive subject must remain validated by you.

How long does it take to review an AI agent's work?

It depends on the volume and the task. At first, plan time to carefully read each draft, as that is where you spot misunderstandings. When corrections disappear, reviewing becomes quick. In automatic mode, a regular check on what has been sent, for example once a week, keeps you in control without taking much of your time.

What to do if an AI agent sent a bad message?

Write to the recipient yourself to correct it, simply and without delay. Then switch the agent back to manual validation, find the cause (unclear instruction, outdated document, unexpected case) and fix it. Only return to automatic after a few sends validated without correction on this type of case.

Describe a simple task, watch the agent prepare it in draft, then validate its first sends yourself before deciding what comes next.
