Resource details

供有编程基础者学习流程与状态管理。

Before you start

Platforms: 依环境确认
Content updated: 2026-10-22

具备 Python、状态和工作流基础；根据官方安装文档选择隔离环境。
真实模型连接通常还需单独安装对应提供商包，准备模型配置和必要密钥。

这里只提供项目导览，未安装实测。先按官方文档核对 Python 与依赖版本，再选择示例。

Common pitfalls

Windows 下不要直接照搬文档的 shell 环境变量写法；按自己终端与模型提供商说明配置。
安装编排库不等于已接上模型；状态持久化、工具权限与失败恢复仍需设计。
