Apply proven design patterns to create maintainable, extensible, and testable code architectures.

Ensure a class has only one instance with global access.

| Singleton | Database connections, configuration managers | | Factory | Creating objects based on runtime conditions | | Observer | Event systems, pub/sub, reactive programming | | Strategy | Algorithms that can be swapped at runtime | | Decorator | Adding features dynamically without inheritance |

應用適當的設計模式（單例、工廠、觀察者、策略等）來解決架構問題。在重構代碼架構、實現可擴展系統或遵循 SOLID 原則時使用。 來源：aj-geddes/useful-ai-prompts。
