Dive Into LangGraph
LangGraph 是由 LangChain 团队开发的开源 Agent 框架。v1.0 是稳定版本，框架能力全面升级，支持中间件、状态图、多智能体等高级功能。本 skill 内容由《LangGraph 1.0 完全指南》提供。
LangGraph 1.0 完全指南：
安装依赖
在本仓库中同步全部依赖：
uv sync
仓库使用 pyproject.toml 声明依赖、uv.lock 固定精确版本。MCP 使用
langchain[mcp] 内置的 langchain.mcp.MCPAdapter。langchain.mcp 命名空间当前仍为
Beta，本 Skill 只面向当前稳定包中的最新接口，不保留旧形态兼容层。
环境变量
使用模型供应商的大模型需要设置环境变量，推荐使用阿里云百炼（DashScope）的模型：
# 阿里云百炼 (DashScope)
# 获取地址: https://bailian.console.aliyun.com/
DASHSCOPE_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1
DASHSCOPE_API_KEY=your_api_key_here
# 火山方舟 (ARK)
# 获取地址: https://console.volcengine.com/ark/
ARK_BASE_URL=https://ark.cn-beijing.volces.com/api/v3
ARK_API_KEY=your_api_key_here
# 或者其他模型供应商...
请将环境变量添加到 .env 文件，并填入你的 API key。
