Which AI agent actions need a human OK?

“Human in the loop” means a person approves some of an AI (artificial intelligence) agent’s actions before they happen. The simplest way to decide which ones: if you cannot undo it in about a minute, the agent asks first. Reading, research, drafts, and notes can run on their own. Anything that sends, spends, publishes, signs, or deletes waits for your OK.

The one-minute undo test

Before you let an agent do something on its own, ask: if this goes wrong, can I undo it in about a minute, before anyone else sees it? A bad draft can be deleted. An email that reached a customer, a paid order, a public post, or a deleted file cannot be quietly taken back. That second group is where a person needs to say yes first.

Which actions run alone and which ask first

Action	Examples	Rule
Read	Open email, files, calendar, account balances	Run alone
Research	Search the web, compare prices, summarize	Run alone
Draft	Write a reply, post, invoice, or order and save it unsent	Run alone
Log	Keep notes, update its own task list or log	Run alone
Send	Email, text, chat message, form submission	Ask first
Spend	Purchase, subscription, free trial that turns paid, trade, transfer	Ask first
Publish	Social post, website change going live	Ask first
Sign	Contract, terms of service, legal or tax form	Ask first
Share or delete	Share a file, add a user, delete files, mail, or records	Ask first

Reading still deserves limits: give the agent access only to the accounts the job needs. See connect only what you need.

What a good approval request shows you

The exact action. The full text of the email, the item and price, or the file to delete, not a summary.
Who it goes to and what it costs. Recipient, store, amount, and account.
Why. One line tying it back to the task you gave.
One action per yes. A yes covers that one action, not similar ones later. A reminder or suggestion from the agent is not a yes either; see a proactive ping is not permission to spend.

How to set up the rule in 5 steps

Write the rule into the agent’s instructions. Paste a short rule into its instructions (the standing text it reads before every task), using the example on this page.
Turn on the platform’s own approval setting. Where your agent tool offers a setting that asks before an action runs, switch it on for sending, buying, and deleting, so the rule does not rely on the prompt alone.
Keep a short allowlist of services. An allowlist is a short list of the only providers and stores the agent may use. Anything not on it, including signing up for a new service, is an ask-first.
Log every action. Record the date, what the agent did, and who approved it, so you can check the rule is working.
Review the rule after the first week. One week in, read the log and adjust using the checklist below.

Example rule to paste into the agent’s instructions:

Before you send, spend, publish, sign, share, or delete anything, stop and ask me. Show exactly what you will do, to whom, and for how much, and wait for a clear yes for that one action. Use only the services on my allowlist. Reading, research, drafts, and notes are fine without asking. Log every action you take.

For the allowlist, keep it to what the job needs: one email provider, one capped payment card, and two or three stores. See whitelist merchants only and virtual cards for AI agents. For the log, see AI agent audit logs.

Review the rule after the first week

Read the log. Did the agent do anything you did not ask for? If so, cut that access before anything else.
Look at what it asked about. Asks that caught a wrong recipient, price, or file are the rule working. Keep them.
Loosen only the safe side. You can let it save drafts to a new folder without asking. Sending, spending, publishing, signing, and deleting stay ask-first.
Recheck after changes. A new model, new tool, or new instructions means a short test round. See how to test an AI agent.

Using an agent to place trades? The same rule applies to every order; see review before place.

Frequently asked questions

What does human in the loop mean for an AI agent?

It means a person approves certain actions before the agent carries them out. The agent does the work up to that point, then stops and waits for a yes.

What should an AI agent be allowed to do on its own?

Things you can undo in about a minute and that nobody else sees: reading, searching, summarizing, drafting, and keeping notes or logs.

Which AI agent actions need approval?

Anything that sends, spends, publishes, signs, shares, or deletes. Those reach other people or cost money, and you cannot quietly take them back.

Does asking for approval make the agent too slow?

Usually not. Most agent work is reading and drafting, so the approvals are a few short yes-or-no checks a day, each with the exact action in front of you.
