Extracts repeated operational mechanics (SDK, API, file-system, or network logic copy-pasted across handlers or actions) into a shared service layer — produces a stepwise migration plan, then applies it caller-by-caller with verification at each step. Use when the same \"how\" recurs across 2+ callers. Not for behavioral cleanup or dead code (use clean-code) or designing a system from scratch (use architect-system). For a quality review after migrating, see review-work.
