-# 图书管理系统
+# 多智能体协同系统 C++ 工程
 
-图书管理系统
+这是一个基于 C++17 和 CMake 的多智能体协同系统骨架工程，实现了核心的调度引擎和智能体管理功能。

+
+## 核心功能模块
+
+### 1. 智能体管理
+- Agent 类的定义和管理
+- 智能体注册、注销和发现
+- 智能体元数据管理
+
+### 2. 执行流引擎
+- 执行流节点定义
+- DAG（有向无环图）解析和执行
+- 串行和并行执行支持
+
+### 3. 上下文管理
+- 全局上下文和节点局部上下文
+- 上下文数据传递和持久化
+
+### 4. 任务调度
+- 任务队列管理
+- 任务状态跟踪
+- 异常重试机制
+
+## 编译与运行
+
+### 编译项目
+```bash
+mkdir build
+cd build
+cmake ..
+cmake --build .
+```
+
+### 运行主程序
+```bash
+./bin/multi_agent_system
+```
+
+### 运行测试
+```bash
+./bin/basic_test
+# 或使用 CMake 测试
+ctest
+```
+
+## 依赖项
+
+- C++17 或更高版本
+- CMake 3.15 或更高版本
+- 标准 C++ 库
+
+## 后续扩展方向
+
+1. 添加 HTTP 客户端支持智能体通信
+2. 实现 JSON Schema 验证
+3. 添加数据库连接支持（MySQL、MongoDB）
+4. 实现 JWT 认证和 RBAC 权限控制
+5. 添加 SSE（Server-Sent Events）流式输出支持
+6. 容器化部署配置
+
+## 注意事项
+
+- 当前为骨架实现，包含核心数据结构和基础功能
+- 实际生产环境需要添加网络通信、数据库持久化等模块
+- 建议结合前端图形化编排器使用
