功能范围

Phase 1: 跨服务业务流程映射

输入：

• 系统架构图（C4 模型或类似）
• API 契约文档
• 业务流程描述（User Journey）

输出：

• specs/workflows/*.md — 业务流程规格
• specs/data-flow.md — 数据流图谱
• specs/error-handling.md — 异常处理场景

Step 1.1: 服务拓扑分析

// services/service-graph-analyzer.ts

interface Service {
  id: string;
  name: string;
  type: 'api' | 'worker' | 'scheduler';
  endpoints?: Endpoint[];
}

interface Dependency {
  from: string;
  to: string;
  protocol: 'http' | 'grpc' | 'message';
  pattern: 'sync' | 'async' | 'saga';
}

class ServiceGraphAnalyzer {
  analyze(configs: any[]): { services: Service[], dependencies: Dependency[] } {
    const services = config.map(c => ({
      id: c.name,
      name: c.displayName,
      type: this.determineType(c),
      endpoints: this.extractEndpoints(c)
    }));
    
    const dependencies = this.extractDependencies(services, configs);
    
    return { services, dependencies };
  }
  
  extractDependencies(services: Service[], configs: any[]): Dependency[] {
    const deps: Dependency[] = [];
    
    configs.forEach(config => {
      // HTTP dependencies
      if (config.services?.forEach((target: string) => {
        deps.push({
          from: config.name,
          to: target,
          protocol: 'http',
          pattern: 'sync'
        });
      }));
      
      // Message queue dependencies
      if (config.topics?.length > 0) {
        config.topics.forEach(topic => {
          deps.push({
            from: config.name,
            to: topic,
            protocol: 'message',
            pattern: 'async'
          });
        });
      }
    });
    
    return deps;
  }
}
