#### 描述
我已经按照这里的指南设置了一个简单的工具调用代理。我使用 `StructuredTool` 类定义了工具，如我的代码所示。当我尝试运行这段代码时，我得到了上面共享的错误。如果我删除工具名称中的空格并用破折号(-)或下划线(_)替换它，代码就可以正常工作，代理执行成功。
我没有在任何地方看到工具名称不应该包含空格，而且Langchain文档中也使用了空格作为工具名称。我是不是漏掉了什么或者犯了什么错误？

函数名不能包含空格。
你可以将其更改为：
parse_docstring = True不是必须的，但我看到你使用了Google风格的文档字符串，所以也许这样会更好。你可以使用
print(add_numbers_tool.get_input_schema().schema())来查看两者之间的差异。或者你可以在LangSmith上进行检查。
