|---|---|---|
| God module | Many unrelated responsibilities | Split by domain |
| Shotgun surgery | One change touches many files | Consolidate logic |
| Feature envy | Module A mostly uses B's data | Move behavior |
| Leaky abstraction | Impl details escape API | Narrow public surface |
| Config soup | Magic strings everywhere | Named constants / schema |
| Boolean flags | if is_x branches everywhere | Polymorphism or strategy |
