LangChain updates Deep Agents with skill support
What happened
On October 8, reports said LangChain updated Deep Agents skill support with tool binding, pinned skills and in-thread reloading, all available in the latest deepagents. With tool binding, a tool can only be called once the matching skill has been read. Apps can use pinned_skills to load chosen skills and their tools before the next model call. In-thread reloading sets skills_metadata to None so the next run rescans the skill library without restarting the thread. The reports also note that discovering new skills changes the system prompt and invalidates the prompt cache.

LangChain 更新 Deep Agents 的技能支持，新增工具绑定、固定技能和线程内重载，均已在最新 deepagents 中提供。绑定工具仅在技能被读取后开放调用；应用通过 pinned_skills 可在下一次模型调用前加载指定技能及其工具。将 skills_metadata 设为 None 可让下一次运行重新扫描技能库，无需重启线程，但发现新技能会改变系统提示词并使提示词缓存失效。
