Why this prompt works

Refactoring prompts are risky if they silently change behavior. This one locks the external behavior, focuses on naming and structure, and requires an explanation per change — so you get cleaner code you can trust and review confidently.

How to customize it

Have tests in place first so you can verify behavior is unchanged.
Refactor in small chunks for easier review.
Keep the change summary with your commit message.

Tip: replace the parts in [square brackets] with your own details before you send. The more specific you are — audience, tone, goal, constraints — the better the AI output.
