Code Refactoring Prompt

Transform messy or hastily-written code into clean, maintainable code while preserving the original behavior exactly. Great to run before a pull request or code merge.

The prompt

Refactor the following code to make it cleaner, more readable, and easier to maintain. Preserve the existing behavior exactly. Explain every change you make and why:

{{code}}

Works in ChatGPT, Claude, Gemini and other assistants. Replace the highlighted placeholders with your own content.

How to use it

Put the code to clean up at {{code}}. The prompt tells the AI to preserve behavior exactly and explain each change, so you can review the reasoning rather than just the result.

Tips for better results

  • Run your existing tests before and after. That is the real proof behavior is preserved.
  • Refactor one function at a time to keep the diff reviewable.
  • Tell it what to leave alone (public API, naming) if there are constraints.
