anti-duplication
Installation
SKILL.md
Code duplication creates maintenance nightmares:
- Bug fixes must be applied in multiple places
- Features evolve inconsistently across duplicates
- Refactoring becomes exponentially harder
- Codebase grows unnecessarily large
- Onboarding takes longer (more code to learn)
This skill transforms "implement X" requests into a two-phase workflow:
- Search phase: Find existing similar implementations (endpoints, components, services, models)
- Reuse or justify: Either reuse/extend existing code OR justify why new implementation is necessary
The result: Codebases stay DRY, maintainable, and consistent.
