Does it automatically delete duplicate code?

No, it acts as a candidate generator that surfaces potential duplicates for developer review, providing specific refactoring patterns to help you consolidate the code manually.

What programming languages does it support?

It is language-agnostic because it uses structural and indentation patterns, making it compatible with Go, TypeScript, Python, C#, Java, Rust, and other text-based languages.

Can I ignore intentional duplication like generated files?

Yes, you can use the -exclude flag to ignore specific file patterns or add specific pattern hashes to the .quickdup/ignore.json file to suppress known duplicates.

How fast is QuickDup at scanning code?

QuickDup is highly optimized, capable of scanning approximately 100,000 lines of code in about 500 milliseconds using structural fingerprinting.

개발자 도구

Detects and helps refactor code duplication and DRY violations to reduce codebase size and improve maintainability.

QuickDup is a high-performance structural code clone detector designed to identify redundant logic and copy-pasted segments across large codebases. It leverages indent-delta fingerprinting to surface duplication candidates in milliseconds, providing specialized workflows for AI-assisted review. Beyond simple detection, the skill helps developers categorize duplication into structural, switch-based, or parameter-bundle patterns, offering specific refactoring strategies to ensure code remains DRY (Don't Repeat Yourself) while maintaining readability and architectural integrity.
