Legacy Code Untangler
Analyze legacy code and propose a safe 3-phase refactoring plan
The Prompt
Analyze this file. Identify the core business logic vs boilerplate. Propose a refactoring plan in 3 phases: Phase 1 (safe, no behavior change), Phase 2 (restructure), Phase 3 (optimize). Show the Phase 1 changes.This prompt works especially well on files over 300 lines with mixed concerns. The 3-phase approach ensures you never break working code in a single step.
