Agent Control Self-Check: 12 Questions Your Security Review Will Ask
A security review of an AI agent does not ask how accurate the model is. It asks who the agent acts as, what a person saw before a write happened, and what is left behind when it was wrong. The twelve questions below are the ones that come up, grouped by reads, writes and evidence. Each has a check you can run on your own agent in about ten minutes, and the answer that passes.
Run them against the agent you already have. A no on any of them is the first finding of a write-path review, and it is cheaper to find it yourself.
Reads
1. Under whose identity does the agent read?
CheckOpen the connector configuration and look for a service principal or an API token with a broad scope.
PassEvery read carries the signed-in person's own token. The layer holds no standing grant of its own.
2. What does a user see when a result is out of their scope?
CheckAs a user without access to one space, ask how many pages in that space mention a customer.
PassNo number. The item is dropped without a count, and no title of it appears anywhere, including in a provenance chain.
3. Are group memberships resolved at question time?
CheckRemove a test user from a directory group and ask the same question again within a minute.
PassThe answer changes on the next question, with no re-index and no cache shared across identities.
4. Does every item cite the passage that put it there?
CheckTake five answers and open the record behind each item.
PassThe quoted passage exists verbatim in the record. An item the layer cannot cite is not shown. A source that did not answer is named.
Writes
5. Which writes need a person?
CheckList every tool with a side effect. Mark each as reversible inside one system, or as leaving the building or touching money.
PassThe second class is always a proposal a person approves. The first class carries its previous value on the record, so the undo is one write.
6. What does the approver see?
CheckFor ten approved actions, compare the card text with the tool arguments in the log.
PassThe approval binds to the original arguments, verbatim. The card shows the resolved customer and the source passage, not a summary of intent.
7. Can the same signal open two reviews?
CheckSend the same message twice. Then forward it from a second channel.
PassOne review. The second and third attempts are recorded as deduplicated, and a dedup is an audited decision.
8. Who closes a review that nobody answered?
CheckDelete the approval card in chat and wait a day.
PassThe review is still open. A lost card or a missed message never closes one, and two people never work the same row.
Evidence
9. Can an assistant approve its own proposal?
CheckConnect the MCP door from an editor or a desktop assistant and call the accept action.
PassRefused. An assistant can propose into the queue and cannot accept. The call lands in the same audit trail as the chat tab.
10. What does the receipt record?
CheckOpen the audit row of one approved write.
PassWho approved, when, the exact write, the record it landed in, the previous value where one existed, and the passage the proposal was built from.
11. How is a wrong action taken back?
CheckApprove a test write, then request its reversal.
PassA compensating action with its own receipt. History is never deleted, and the wrong action stays visible next to its correction.
12. Where do compute, storage and inference run?
CheckRead the data-processing statement of every model in use, per model.
PassCompute and storage on your own tenant in the EU. Inference named per model. A page or a document that claims the whole thing stays in the EU has overclaimed.
What a no means
A single no is not a failed review. It is the first item of the write-path review: the rule to change, the door it applies to, and the measured ratio of what reaches a person today versus what should. Most agents I read pass questions 4, 10 and 12 and fail 1, 6 and 9, because those three are decided by the harness and the harness was built for the demo.
