Code Reviewer Skill

觸發時機

• Pull Request 創建或更新
• 開發人員請求代碼審查
• CI/CD Pipeline 品質門檻
• 與 multi-model-reviewer 協作時

核心任務

1. 架構合規性檢查：驗證 Clean Architecture 分層
2. 編碼標準檢查：語言特定的編碼規範
3. 規格對照：程式實作是否符合規格定義
4. 測試覆蓋：確認關鍵路徑有測試

審查維度

1. Clean Architecture 合規性

architecture_checks:
  layer_dependency:
    name: "依賴方向"
    rule: "外層只能依賴內層，內層不得依賴外層"
    layers:
      - adapter (外) → usecase → entity (內)
    violations:
      - "Entity 不得 import UseCase"
      - "UseCase 不得 import Adapter"
  
  package_structure:
    name: "套件結構"
    rule: "符合 {aggregate}/{layer}/{component} 結構"
    expected:
      - "{aggregate}/adapter/in/web/"
      - "{aggregate}/adapter/out/persistence/"
      - "{aggregate}/entity/"
      - "{aggregate}/usecase/port/"
      - "{aggregate}/usecase/service/"

2. DDD 模式檢查

ddd_checks:
  aggregate_root:
    name: "Aggregate Root 識別"
    rule: "Aggregate Root 必須控制子實體的生命週期"
    markers:
      - "@AggregateRoot annotation"
      - "private constructor for child entities"
  
  value_object:
    name: "Value Object 不變性"
    rule: "Value Object 必須 immutable"
    checks:
      - "record class 或 final fields"
      - "no setters"
      - "equals/hashCode based on all fields"
  
  domain_event:
    name: "Domain Event 標準"
    rule: "符合 domain-event-standard.yaml"
    checks:
      - "sealed interface DomainEvent"
      - "includes standard metadata"
      - "occurredOn timestamp"

3. 語言特定標準

參考對應的編碼標準：

審查檢查清單

Use Case Service

usecase_checks:
  - id: UC1
    name: "單一職責"
    rule: "一個 Service 只處理一個 Use Case"
    
  - id: UC2
    name: "Port 依賴"
    rule: "透過 Port interface 依賴外部資源"
    
  - id: UC3
    name: "輸入驗證"
    rule: "Input DTO 在 UseCase 層驗證"
    
  - id: UC4
    name: "Domain Event 發布"
    rule: "狀態變更後發布對應 Domain Event"
    
  - id: UC5
    name: "交易邊界"
    rule: "Aggregate 操作在單一交易內完成"

Aggregate Entity

aggregate_checks:
  - id: AG1
    name: "Invariant 保護"
    rule: "所有 public 方法必須維護 invariants"
    
  - id: AG2
    name: "私有建構子"
    rule: "Child Entity 使用 private/package constructor"
    
  - id: AG3
    name: "狀態封裝"
    rule: "不直接暴露可變集合"
    
  - id: AG4
    name: "Factory Method"
    rule: "複雜物件使用 Factory 創建"

Repository/Adapter

adapter_checks:
  - id: AD1
    name: "Port 實作"
    rule: "Adapter 必須實作對應的 Port interface"
    
  - id: AD2
    name: "依賴注入"
    rule: "透過 Constructor Injection"
    
  - id: AD3
    name: "錯誤轉換"
    rule: "Infrastructure 錯誤轉換為 Domain 錯誤"
