UnverifiedA common way to handle duplicate operations caused by retries is to carry a unique idempotency key in the request, letting the receiver determine from that key whether the same operation has already been processed, thereby safely ignoring duplicate requests.75% similarUnverifiedFor agent workflows, retries must carry the same idempotency key; if a new key is generated on every retry, the idempotency protection is completely defeated.71% similarUnverifiedFunction Calling机制的核心缺陷在于每次工具调用都需要完整的一轮请求-响应循环，Token消耗随调用次数线性增长69% similarUnverifiedThe smart retry mechanism in v2.0 retries only the failed targets when sending to multiple destinations, rather than resending to all of them.69% similarUnverifiedFor creation-type endpoints, if the endpoint is not idempotent, retrying due to a timeout will create two tasks, resulting in duplicate charges68% similar
