description: Detects similar or copy-pasted code and suggests DRY refactors (shared functions, params, generics). Use when code similarity or repetition is noticed.

Duplicate Code Detector

When to Trigger

  • •Code similarity >70%
  • •Copy-paste detected
  • •Similar patterns in multiple places

What to Do

  1. •Find: Functions or blocks that differ only by a few values (e.g. status, filter).
  2. •Refactor: Single function with parameters (e.g. getBookingsByStatus(status)) or generic helper with options object.
  3. •Reuse: Extract to shared util, hook, or service; call from original call sites.
  4. •Types: Use shared types/interfaces so refactor stays type-safe.

Prefer small, focused helpers over large generic functions. Preserve behavior and add/run tests if touching critical paths.
