一个智能体可以完成任务，但走的路径却并不高效。一次失败的搜索可能触发另一次搜索。一次被截断的文件读取可能导致命令再次获取相同内容。正确的最终答案往往掩盖了这些额外步骤，尽管它们增加了延迟并消耗了更多Token。低效操作也会增加失败的风险。 为了改进智能体的行为，开发者必须理解任务是否成功，以及智能体是如何完成任务的。仅凭成功检查无法解释智能体为何从工具错误中恢复、为何提前停止，或为何需要额外的模型 ...

搭一个 AI Agent Demo，可能一个下午就够了。但要把它真正做到可以投入生产，完全是另一回事。 一个生产级 Agent 必须稳定在线、足够安全、控制好成本，而且当它不可避免地出问题时，你还得有足够的可观测性去弄清楚到底哪里出了错。这些能力几乎都不是模型本身提供的，而是来自你围绕模型搭出来的所有东西：记忆、工具访问、模型路由、护栏、成本控制，以及当 ...
