DDD 架構輔助技能

觸發：新增功能/模組、架構檢查、建立新檔案時自動檢查

工具：grep_search（搜尋 import）、list_dir、read_file、create_file

層級結構

src/domain/ → entities, value_objects, aggregates, repositories(介面), services src/application/ → use_cases, dtos src/infrastructure/ → persistence, services(外部服務實作) src/interfaces/ → api, mcp

依賴規則

✅ Presentation → Application → Domain ← Infrastructure（實作介面） ❌ Domain → Infrastructure, Domain → Application, Application → Presentation
