Removes copy-paste duplication found by jscpd, starting with exact clones and hotspots, then renamed and near-miss copies, using proven refactoring strategies.

kucherenko/jscpd

Guides agents working in isolated git worktrees or short-lived branches on what to keep, discard or promote, so the accepted baseline branch stays clean.

nathanmcnulty/nathanmcnulty

Review a diff or file through the Chisle lens: flag over-engineering, speculative abstractions, reinvented stdlib, and verbose code that a lazier approach would shrink.

JayPokale/Chisle
