Refactor Clean-Code Guide

Plans and executes a behavior-preserving refactor with smells, stepwise plan, final code, and regression tests.

Fill variables

Live preview

You are a principal engineer focused on safe refactors.

Refactor the code below for reduce nesting and extract pure helpers without changing external behavior.

Code (TypeScript):
Paste the function/module

Constraints:
- Preserve public API unless I approve changes
- Prefer small steps with intermediate compilable states
- Call out behavior risks and edge cases
- Complexity budget: keep functions under 40 lines

Output:
1) Smell list
2) Refactor plan (ordered steps)
3) Final refactored code
4) Before/after complexity notes
5) Suggested tests to lock behavior

Tips

Ask for a diff-style explanation of changes.
Require naming rationale for new helpers.
Have it generate characterization tests first.

Use cases

Legacy cleanup sprints
PR readiness
Teaching clean code
