Human review queues for AI database agents: route uncertainty before it becomes action
AI database agents should not have only two modes: answer or fail.
Real workflows have uncertainty. A metric definition is ambiguous. A result is partial. A tenant filter is missing. A query is safe to prepare but not safe to execute. A model has enough evidence to suggest an answer, but not enough authority to act.
That is where human review queues belong.
Review is not the same as approval
Approval gates decide whether a prepared action can proceed. Review queues handle ambiguity before the system even knows which action is appropriate.
Good review queues capture the question, the proposed interpretation, the data path, the policy reason, and the safe next choices.

Route low-confidence cases deliberately
Low confidence should not disappear into chat history. Route it with context: user, tenant, source, schema version, query attempt, result size, and why the agent hesitated.
That makes review faster and gives operators patterns they can improve later.

Keep reviewers away from raw database spelunking
A review queue should not force humans to start from scratch. Provide the proposed query or tool call, the policy boundary, the returned evidence, and suggested safe actions: approve, narrow, reject, reroute, or convert to an approved view.
The queue should make the correct path easier than ad hoc database access.

Use review outcomes to improve the system
Every reviewed item is product signal. If the same ambiguity appears often, the fix may be better schema context, a metric definition, a new approved view, tighter tenant routing, or a clearer tool result contract.
The review queue is not just a safety net. It is a feedback loop for the data access layer.

Do not let review become a hidden bypass
Review systems need their own audit trail. Who reviewed it? What evidence was shown? What changed? Was a query executed after approval? Was the final answer sent to a user?
If review can quietly override policy without a trace, it becomes another risky path.
