AI agent retry safety means the system must know whether a consequential external action failed before repeating it. If the action may have succeeded and retry could duplicate the effect, the system should stop and obtain evidence.
Why retries become dangerous
Agents often retry after timeouts, network errors, missing receipts, or downstream failures. That is safe only when the system knows the original action did not complete or the action is truly idempotent.
Four execution states
A practical model distinguishes NOT ATTEMPTED, ATTEMPTED — CONFIRMED FAILED, COMPLETED, and STATUS UNKNOWN.
Status unknown is not failure
If an email send, payment, form submission, publish action, or record change may have succeeded, local uncertainty must not be converted into confirmed failure.
Evidence before retry
The system should check provider status, external records, message IDs, transaction IDs, target state, or other evidence before repeating the action.
Recovery after uncertainty
If the status cannot be resolved, the workflow should escalate and keep the affected action blocked while unrelated safe work continues.
How this fits the Catha AI Governance Build Kit
This topic is one part of the broader Catha AI Governance Build Kit, a fourteen-stage build process covering business outcome, governance discovery, authority, rules, permissions, autonomy, workflow design, validation, receipts, production approval, monitoring, recovery, final readback, and platform export.
The governance baseline belongs to the business. Platform-specific implementation may differ, but approved authority, rules, permissions, autonomy, approvals, and evidence requirements should not silently change.
Questions businesses ask about this topic.
What causes duplicate agent actions?
Common causes include scheduler reruns, timeouts, lost local state, missing receipts, downstream retries, and manual action performed while automation is still pending.
Can retry limits alone solve the problem?
No. A limit controls frequency, not whether a retry is safe.
What if the action is idempotent?
True idempotency can make retries safer, but the system should document and verify that behavior rather than assume it.
