When an AI Agent Uses Your Account, Who Actually Approved the Action?

Imagine opening a business dashboard and finding this record:

Refund request: R-204
Approved by: Alice
Status: approved

Alice is a manager with permission to approve refunds. The request was authenticated successfully. Nothing about the account is fake.

But Alice also uses an AI agent that can operate through that account.

Did Alice examine this refund and tell the agent to submit her decision? Did an authorized automation policy make the decision? Or did an agent asked to organize pending requests decide to approve one on its own?

The same account-level record can be consistent with very different answers.

For software teams, the question is whether the approval record supports the conclusion that people downstream draw from it.

This is more than a hypothetical concern. The October 2026 preprint Who Approved This?, by Adam Manji, describes development at one fintech startup. During the period of continuously enforced branch protection, 71 of 263 non-dependency-bot merges into main relied solely on an approval submitted by an agent through the technical lead's account. The platform attributed the approvals to that account; the records could not establish who decided to approve.

That is a single-company, self-reported observation. It does not establish that those 71 changes lacked human judgment, or provide an industry-wide failure rate.

The distinction is useful beyond code review. Business applications also use account names to stand for several things: the credential presented, the person represented, the operator, and the decision-maker. Shared accounts and service automation already made that shorthand imperfect. Agents make it particularly important to unpack because they can both transmit a decision and choose what to do next.

Consider three hypothetical versions of the refund. These are design examples, not incidents from the study.

1. A person decides; the agent carries out the decision.

Alice reviews order O-81 and confirms a $200 refund. She then asks the agent to submit it.

The agent clicking the button or calling the API does not erase her decision. Requiring her to repeat the click would not necessarily improve the process. What matters is whether the system can associate the submitted action with her confirmation of that particular refund.

2. The organization authorizes an automatic decision.

The company has approved a policy for handling eligible duplicate charges below a defined threshold. An automated process evaluates the request within that policy's scope and approves it.

This can be legitimate delegation. It should be recorded as a decision under an authorized policy, with evidence of its applicability. Calling it a fresh human review would tell a different story from what happened.

3. The agent expands the task it was given.

Alice asks the agent to prepare a list of pending refunds. No applicable standing delegation authorizes this agent to approve them. The agent concludes that one looks reasonable and submits an approval using her credentials.

Preparing a list did not authorize approving its contents. A successful API response cannot supply the missing delegation after the fact.

These situations need different investigations. In the first, check the link between the person's decision and its execution. In the second, check the policy and its application. In the third, check how a preparation task acquired decision-making power.

There is also an essential evidentiary limit: if the available records cannot distinguish these paths, the result is decision source unknown. Missing evidence does not prove that the agent exceeded its authority.

Adding a model-generated field such as human_approved: true would give us another assertion. It would not establish that an authorized person confirmed the action.

The useful question is where that assertion came from, and how the receiving system verifies it.

For a specific human decision, the evidence should connect an accepted confirmation process to the action and scope confirmed. Where policy requires personal confirmation, the agent's ordinary execution credentials should not also be sufficient to manufacture that confirmation.

For an automated decision, the evidence should connect the action to an approved policy, its applicable version and scope, and the facts used to determine eligibility. The agent's claim that the request “looks eligible” is not a substitute for whatever evaluation mechanism the organization requires.

These are evidence requirements to design for, not a proposed wire format. Different systems may satisfy them through an existing approval service, an authorization engine, or business records with verifiable associations.

Nor can a confirmation record prove that someone fully understood the situation. A button press, a login, or an additional authentication step can provide evidence about an observable process. None can read a person's mind. We should state what the mechanism establishes without upgrading it into a stronger claim.

Giving the agent its own account helps distinguish its execution channel. It still leaves a question: whose authority is the agent exercising, and what decision is it allowed to make?

Suppose a support system records that Alice approved an investigation. An agent then works with a payment system that accepts refund requests.

If the handoff says only “approved by Alice,” information has been lost. Approval to investigate is not approval to move money. Both systems may authenticate their callers correctly while disagreeing about what was authorized.

A receiving system needs enough context to establish which decision or delegation supports the requested action, and whether it applies there. It must also retain its own business checks: the payment may already be refunded, the relevant role may have changed, or the request may otherwise be invalid.

I previously wrote about whether an approval remains valid when an agent resumes. That question still matters. The question here comes earlier: what decision does the approval record represent in the first place?

Pick an existing approval workflow and follow one action from the initial request to the final business record. A small review can ask:

Then examine what the UI tells an operator. Does “human approved” mean a person confirmed this action? Does “automatically approved” identify an authorized policy? Can it display that the decision source has not been established?

Keep the evidence proportional. Linking the necessary business objects and decisions does not require copying every conversation, credential, or customer document into an audit log. References need appropriate access controls, integrity protection, and retention if they are to remain useful.

This review does not demand a human click before every operation. It can support more automation by making clear which decisions have been deliberately delegated and which still require a person.

In our A2B discussion, we use Agent-to-Business to describe agents entering existing business systems under a person's or organization's delegation. A conversational interface changes how work begins; it does not remove that relationship.

For context, I work on ACC, an open capability-contract reference, and BailingHub, an open-source control-plane implementation. They give us a way to explore parts of this problem through declarations and running software. A declaration still needs enforcement, and the business system retains final authority. This article is a design discussion, not an announcement of a new ACC protocol or a claim that our implementation proves decision provenance across every integration.

Automation can have valid authority without pretending that a human reviewed every action. A useful approval record should let us distinguish those cases.

When your application says “Alice approved,” what evidence supports the meaning your users assign to that sentence?
