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 |

Apply appropriate design patterns (Singleton, Factory, Observer, Strategy, etc.) to solve architectural problems. Use when refactoring code architecture, implementing extensible systems, or following SOLID principles. Source: aj-geddes/useful-ai-prompts.
