1. 1jscpdverified and signedpassport

   skillkucherenko/jscpdrecord

   • jscpd

     Copy-paste detector for 220+ languages. Detect exact, renamed and near-miss duplicated code, measure duplication percentages, and find refactoring hotspots with the codebase summary.

2. 2jscpd-copy-paste-detectorverified and signedpassport

   librarykucherenko/jscpdrecord

   • kucherenko/jscpd

     Copy/paste detector for source code — find duplicated blocks across 223+ languages (Rust v5)

3. 3codebase-refactoringverified and signedpassport

   skillkucherenko/jscpdrecord

   • codebase-refactoring

     Three-part workflow to improve overall codebase health with jscpd — find and fix duplicated code, find and remove or refactor dead code, then find and simplify the largest/most complex files. Starts from --dashboard/--health to prioritize and ends by re-measuring the score.

   • jscpd_detect_clones

     Code clones via rolling-hash fingerprinting. max_results scales output. ~300-2000tok

5. 5dry-refactoringverified and signedpassport

   skillkucherenko/jscpdrecord

   • dry-refactoring

     Guided workflow to eliminate copy-paste duplication detected by jscpd. Refactor exact, renamed and near-miss clones using extract function, parameterize, module, constant, or base class strategies, starting from the hotspots the summary ranks.

6. 6code-graph-rag-mcpfound in code, not yet checkedno passport yet
   • jscpd_detect_clones

     Use when: you want fast, tokenizer-based duplicate detection (no embeddings). Typical flow: jscpd_detect_clones(paths, formats) → review clone blocks → refactor. Output: clone blocks with locations; best for quick duplication sweeps.

   • detect_code_clones

     Use when: you want semantic clone groups across the codebase. Typical flow: detect_code_clones → prioritize hotspots → suggest_refactoring. Output: clone groups; consider jscpd_detect_clones for fast tokenizer-based scanning.
