LangSmith 推出 Trajectories 功能，聚合展示智能体会话全流程
LangChain 给 LangSmith 加了个 Trajectories 视图，能把主 agent 和子 agent 的消息、工具调用按顺序拼成对话，调试 agent 时一眼看懂。
LangChain 在 LangSmith 中推出 Trajectories 视图，用于查看智能体的会话行为。
该功能把 Human 消息、AI 消息、Tool 消息和 System 提示词整合成对话式呈现。Trajectories 覆盖主 agent 与所有 subagents，并按消息首次出现的顺序排列，方便团队成员一眼理解 agent 的运行过程。
What is a trajectory? A conversational view of an agent session that pulls together: ✅ Human messages ✅ AI messages ✅ Tool messages ✅ System prompts …across the main agent + any subagents, then shows them in the order they first appeared.
