Unverified50% confidenceCautionExact time
Saving a checkpoint does not automatically make external side effects safe to retry; if the agent had already initiated a refund through a payment API before crashing, replaying from the checkpoint could result in a duplicate refund.

UnverifiedSafe recovery of persistent agents requires distinguishing replayable operations (such as reading files and analyzing code) from non-replayable side-effect operations (such as writing files and committing changes), the latter requiring precise progress tracking to avoid repeated execution.74% similarUnverifiedIf the Agent state is lost after an approval is triggered and it is forced to start over, it may cause side effects from re-executing already completed steps, such as sending duplicate messages or charging twice.71% similarUnverifiedAfter the fix, the payment provider's retry bug was directly exposed in the next round of testing, because the retry was actually captured instead of hitting a URL that had disappeared.71% similarUnverifiedUsing refund-${email_id} as the idempotencyKey when issuing a refund ensures that crash retries will not result in duplicate refunds.71% similarUnverifiedWhen the API is unavailable, applications should implement graceful degradation by returning cached results, prompting users to retry, or switching to a fallback solution, rather than crashing directly70% similar
