🚨 發現的關鍵相容性問題：

高風險：

1. customer-identity-service Token Format Change
   Impact: All 11 downstream services affected
   Risk: Authentication failures, service outages
   Mitigation: Implement dual-token support for 2-week transition period

   Required Changes:
   - Update JWT validation logic in all consuming services
   - Implement backward compatibility layer
   - Coordinate token migration across all environments

2. data-ingestion-service Event Schema Breaking Changes
   Impact: Analytics pipelines, customer profile updates
   Risk: Data loss, processing failures
   Mitigation: Schema versioning with parallel processing

   Required Changes:
   - Support both v1 and v2 event schemas simultaneously
   - Implement schema migration tools
   - Update all event publishers to new format

中度風險：

3. customer-profile-service API Response Changes
   Impact: 5 consuming services need updates
   Risk: UI display issues, integration failures
   Mitigation: API versioning with gradual migration

   Required Changes:
   - Implement /v2/profile endpoints
   - Maintain /v1/profile for 6 months
   - Update consuming services incrementally

Azure DevOps MCP 整合的最佳實踐

安全和存取管理

代幣管理：

使用細粒度的個人存取令牌，並盡量減少所需範圍
實施代幣輪調政策（最長 90 天）
使用 Azure Key Vault 或類似服務安全地儲存令牌
定期審核令牌的使用和存取模式

權限最佳實踐：

{
  "recommended-scopes": [
    "vso.work_write",           // Work item management
    "vso.code_read",            // Repository access
    "vso.build_read",           // Build pipeline monitoring
    "vso.test_read",            // Test result analysis
    "vso.project_read"          // Project information
  ],
  "avoid-scopes": [
    "vso.profile",              // Unnecessary for most use cases
    "vso.connected_server",     // High privilege, rarely needed
    "vso.machinegroup_manage"   // Infrastructure management
  ]
}

效能最佳化

API 使用模式：

對頻繁存取的資料實施智慧型緩存
盡可能使用批次操作來減少 API 呼叫
利用 OData 過濾來最大限度地減少資料傳輸
使用指數退避演算法實現重試邏輯

資源管理：

// Example: Efficient work item querying
const workItemQuery = {
  wiql: `
    SELECT [System.Id], [System.Title], [System.State]
    FROM WorkItems 
    WHERE [System.TeamProject] = @project
    AND [System.State] <> 'Closed'
    AND [System.ChangedDate] >= @today-30
    ORDER BY [System.ChangedDate] DESC
  `,
  top: 200  // Limit results for performance
};
