Expert guidance for implementing Command Query Responsibility Segregation (CQRS) and Event Sourcing patterns to build scalable, auditable systems with complete historical tracking and optimized read/write models.

Command Query Separation Separate operations that change state (commands) from operations that read state (queries).

| Express intent (CreateOrder, UpdatePrice) | Return data, never change state | | Can be rejected (validation failures) | Can be cached and optimized | | Return success/failure, not data | Multiple models for different needs | | Change system state | Eventually consistent with writes |

CQRS 和事件源模式适用于具有独立读/写模型的可扩展、可审计系统。在构建需要审计的系统、实现时态查询或设计具有复杂域逻辑的大规模应用程序时使用。 来源：nickcrew/claude-ctx-plugin。
