Unverified在Agent Loop中如果只将工具结果塞回messages而漏掉assistant消息，模型会陷入无限循环，不断重复调用工具75% similarVerifiedIn scenarios where an Agent automatically executes multi-step tasks, a failure at one step can cause the entire workflow to fail or even trigger cascading erroneous operations.74% similarUnverifiedBecause LLM calls carry uncertainty and the possibility of failure, an Agent scheduler must have built-in retry mechanisms and idempotency guarantees; otherwise, a single network blip could cause the Agent to execute repeatedly and produce irreversible side effects.73% similarUnverifiedIn an Agent system, an error in any intermediate step can cause the entire pipeline to fail, making comprehensive logging and error-retry mechanisms a necessary guarantee for stable operation.72% similarUnverifiedThe core challenges of the Agent Loop include preventing runaway loops (by setting a maximum number of steps), handling error recovery from failed tool calls, and maintaining reasoning quality without degradation over long contexts.72% similar
