Use this template to refactor legacy code toward a stated goal, with safety.
INPUTS
- •Code - the code to refactor
- •Refactor goal - e.g., improve readability, adopt a pattern, reduce coupling
- •(optional) Constraints
INSTRUCTIONS
- •Restate the refactor goal and constraints. Preserve behavior.
- •Propose a target design (patterns, boundaries, contracts).
- •Provide a refactored version or representative slices.
- •Explain rationale trade-offs (perf, readability, testability).
- •Add safety checks: tests, metrics, and rollout steps.
- •Show an incremental plan of small commits.
- •Keep lines ≤80 chars.
