上述代码实现了基于Mesa框架的诊断智能体类，包含以下核心功能：

1. 模块化设计：通过类属性分离数据与行为，支持不同专科智能体的扩展
2. 状态管理：实现idle/processing/error等状态转换，支持任务调度
3. 诊断推理：集成机器学习模型，支持症状提取与多分类诊断
4. 错误处理：包含模型加载失败的降级策略，确保系统鲁棒性

在实际应用中，可通过Mesa的DataCollector类收集诊断准确率、处理时间等性能指标，通过BatchRunner进行多轮仿真优化智能体配置。

SPADE框架通信协议实现

SPADE框架基于XMPP协议实现智能体间通信，以下是医疗场景下通信协议的实现代码：
