Agent retried a payment after timeout? Give write ops unique IDs and a way to check
gethackteam · x · 2026-09-17
A sharp agent-engineering lesson: when an agent retries a payment after a timeout, no prompt can tell whether the first request failed or the response got lost while the operation actually succeeded.
The fix is engineering, not prompting: give write operations unique IDs and provide a way to check what actually happened, so idempotency and state verification are built into the tooling rather than left to the model's guess.
