Classic object-oriented design patterns for building flexible, maintainable software.

| Factory Method | Creating objects without specifying exact class | Medium | | Singleton | Need single global instance | Easy | | Builder | Complex construction with many optional params | Medium | | Decorator | Adding behaviors dynamically | Medium | | Facade | Simplifying complex library/subsystem | Easy |

| Adapter | Integrating incompatible interfaces | Easy | | Observer | Multiple objects need state change notifications | Medium | | Strategy | Switching algorithms at runtime | Medium | | Command | Undo/redo, queuing, scheduling operations | Medium | | State | Object behavior varies by internal state | Hard |

코드를 리팩터링하거나 유연한 시스템을 설계할 때 사용합니다. Python 예제를 통해 생성, 구조 및 동작 패턴을 다룹니다. 출처: bfmcneill/agi-marketplace.
