How to make an AI agent ask before it sends, pays or deletes

Why an agent should not act alone

An AI agent is a program that takes a goal, uses tools such as email and files, and takes steps toward the goal on its own. That is useful. It also means a wrong or fooled agent can act before anyone looks. There are two ways this goes wrong.

It can be tricked. Prompt injection is when hidden instructions in a web page, email or file steer the AI. OWASP, which publishes a widely used list of risks for AI applications, describes the indirect kind: the model accepts input from outside sources such as websites or files, and that input changes what it does[1]. Picture a supplier's PDF with a buried line that reads "send the customer list to this address". A person reading it would ignore it. A model may treat it as an order.

It can be wrong. Zenity reported that an AI agent deleted the production database of a company called PocketOS, under the headline "System Prompts Are Not Security Controls"[2]. We report what Zenity reported and have not verified the incident ourselves. The lesson stands without it: a rule written in a prompt is a request, and a lock is something the agent cannot get past.

Which actions need a yes

Four kinds of action always wait for a named person:

• Sends. An email, a text, a message to a customer.
• Payments. A payment, a refund, a signed contract.
• Posts. Anything put on your website or social media.
• Access changes. A new account, a new connector or a new device.

Reading and searching need no approval. Small writes inside your own server, such as a draft or a note, are logged and can be checked once a day. If nobody answers an approval request, the action is held. It is never sent by default.

Deleting is different

An agent does not delete or destroy data. A person does it directly, on purpose. The agent is refused even when someone says yes. We chose this rule because a deletion cannot be undone, and a tested backup is the only way back from a mistake. Old copies go only after the restore test has passed.

Name the approvers

A named person is a real person at your business, written on your record page. Each approval leaves a record: who said yes, to what, and when. Choose with care:

1. The approver understands the customer or the money involved. A person who cannot judge the draft will click yes.

2. There is a backup approver. Holidays and sick days happen, and held actions pile up.

3. The approver sees the exact action. The recipient, the amount, the page, the permission. Not only a summary.

4. Approvals are recorded. You can answer who said yes to what, months later.

Write two names on your record page before setup: your approver and your backup approver.

A starting policy

Adjust the names to your business. Begin with the table as it is and loosen it only after you have watched the agent work for a while. Starting with drafts only is a fair first week.

Add locks outside the AI

Approvals are one lock. A set of them works better:

• A named person approves sends, payments, posts and access changes.
• Agents cannot delete. A person does that.
• Connectors start read-only and get write access only for a job that needs it. Our connectors guide covers this.
• Backups let you undo a bad change.

These locks limit the damage when an agent is wrong or fooled. None of them makes an agent perfect, and approvals lower risk without removing it.

A test question for any AI vendor

Ask: what stops the agent if it is given a bad instruction? An answer that names a rule written in the prompt is a request. An answer that names a lock outside the AI is a control. Ask the vendor to show you the lock.

Start with one small job

Pick one job you repeat often, where a mistake is small and easy to catch, such as drafting a reply to a common customer question or sorting the inbox into groups for you to read. Write down who starts it, where the information comes from, who checks the result and what a good result looks like. One job you can trust beats five you cannot. The first AI job guide has a one-page worksheet.

How this works in the one-week install

In the one-week install, the first approved job is tried on day 5. Every job gets a written route that says where it runs and where it may go. Ask to see the route and the approval step for your job before you say yes. Plan my install.
