想对比 Cursor、Claude Code、Codex 的代理行为？LangChain 出了个插件，把它们的 trace 统一到 LangSmith 里，方便你直接看模型和工具调用链。
LangChain 发布了一个 tracing 插件，能将每个 @cursor_ai 代理会话转换为 LangSmith 中的结构化 trace，包含模型运行、每个工具调用以及嵌套子代理工作。附件会被恢复并内联渲染。这是系列视频的第三个，之前有 Claude Code 和 Codex 的 trace，三者使用相同 schema，可在一个地方对比。

We built a tracing plugin that turns every @cursor_ai agent session into a structured trace in LangSmith: the model run, every tool call underneath it, and any nested subagent work. Attachments get recovered and rendered inline too. This is the third video in our coding-agent tracing series (Claude Code, Codex, Cursor). All three share the same trace schema, so you can compare them in one place. Your browser does not support the video tag. 🔗 View on Twitter 💬 0 🔄 0 ❤️ 0 👀 94 ⚡
