UnverifiedCommon termination strategies for Agent Loop include three layers: semantic termination (such as detecting the Final Answer marker), an iteration limit (max_iterations typically defaults to 10–15), and timeout protection (the timeout parameter).85% similarUnverifiedWhen using the legacy Agent, one should set max_iterations to prevent infinite loops, set timeouts, add early_stopping_method=generate, add input validation to tools, and integrate LangSmith for full-chain tracing.68% similarUnverified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66% similarUnverifiedAgent死循环归根结底有三类：单一工具动作无限重复、双状态来回横跳（ABAB式往复）、工具调用持续失败却无脑重试64% similar
