The automation failure nobody budgets for: the action landed, but the timeout said it failed

Reddit r/AI_Agents News

Summary

The article discusses a critical automation failure mode where actions succeed but responses time out, leading to duplicates, and advocates for using stable operation IDs and state checks to improve agent evaluation robustness.

A common agent test is whether the happy path works. The harder test is this: the external system completes the action, the response times out, and the agent retries. Now you have two tickets, two emails, or two purchases. The guardrail that matters is not a better retry prompt. Give every intended effect a stable operation ID, read back the external state after an ambiguous response, and only retry when you can prove the first attempt did not land. We have found this failure mode more useful than most model benchmarks because it tests whether the surrounding system can distinguish failed from unknown. What ambiguous-result scenario do you include in your agent evals?
