FAQPage Schema
How do I detect duplicate code across my Python and JavaScript projects?▼

Duplicate code detection uses PMD CPD for exact matches and Semgrep for pattern-based clones across files. This identifies DRY violations in multi-language codebases, enabling you to plan refactoring with combined results from both tools.

What's the difference between exact duplicates and pattern-based code clones?▼

Exact duplicates are identical code blocks PMD CPD finds line-for-line; pattern-based clones are structurally similar code Semgrep detects with variations in variable names or logic flow. Combined detection catches both violation types for comprehensive refactoring planning.

Can I use this to find code clones across multiple repositories?▼

Yes. The Skill applies PMD CPD and Semgrep across repositories and files in multi-language projects, synthesizing results to surface clones at any scale and guide safe edits with test preservation.

How do I safely refactor detected clones without breaking tests?▼

The Skill guides user-driven refactoring with detection, analysis, and safe edits that preserve test history. You review presented clones, plan extractions, and apply changes while maintaining test coverage.

Does this work with languages beyond Python and JavaScript?▼

This Skill is tuned for Python and JavaScript. PMD CPD and Semgrep support additional languages; coverage depends on tool-specific language support and your project setup.
