Refactor Code Prompt

Refactor the selected code to improve its design, readability, and maintainability without changing its external behaviour.

Refactoring Goals

Select all that apply or add your own in the "Custom Goals" section below:

• Reduce duplication (DRY principle)
• Improve naming clarity
• Break up large functions or classes (Single Responsibility Principle)
• Replace magic numbers/strings with named constants
• Improve error handling
• Simplify complex conditional logic
• Improve performance (specify hotspot if known)
• Add or improve type annotations
• Migrate to a newer language feature or API

Custom Goals

Constraints

• Do not change observable behaviour. All existing tests must still pass after the refactor.
• Keep the public API (exported function/class signatures) identical unless explicitly asked to change it.
• Preserve existing comments that remain accurate; remove comments that are no longer relevant.
• Make incremental changes so each step is reviewable.

Output Format

For each change, provide:

1. What – A one-line description of the change.
2. Why – Why this improves the code.
3. Before – The original code snippet.
4. After – The refactored code snippet.

End with a diff-style summary or the complete refactored file(s).
