Use when user asks about onion architecture, 洋葱架构, Jeffrey Palermo, concentric architecture, or needs layered domain isolation.

Architecture selection decision guide — help users choose from 5 DDD architectures (Layered/Onion/Hexagonal/Clean/COLA) with decision matrix, team size mapping, domain classification (core/generic/supporting), microservice splitting recommendation, and CQRS level suggestion. Use when user asks about architecture selection, 架构选型, COLA vs 六边形, cleaner architecture vs onion, 微服务拆分, or which architecture to use.

DDD code review and anti-pattern detection — anemia model detection, layered compliance checking, aggregate design review, rich model verification, scoring system (5 dimensions), and ArchUnit automated validation. Use when user asks about code review, 代码审查, DDD review, 架构审查, anti-pattern detection, 反模式检测, or needs to check if code follows DDD.

Comprehensive guidance for CQRS Architecture — independent CQRS skill covering L1/L2/L3 implementation levels, Event Sourcing, idempotency design, domain event lifecycle, and architecture-specific CQRS integration patterns for Layered/Onion/Hexagonal/Clean/COLA. Use when user asks about CQRS, 读写分离, Event Sourcing, 事件溯源, Command Bus, Query Model, or domain events.

DDD DevOps integration — CI/CD pipeline with ArchUnit automated architecture validation, multi-module build optimization for DDD projects, containerized deployment with Docker/K8s for layered/hexagonal/clean architectures, database migration strategies for domain events, and monitoring domain health. Use when user asks about DevOps, CI/CD, DDD deployment, ArchUnit CI, or needs to automate DDD project builds.
