Code Refactoring Suggestions

Purpose

Help developers improve existing code by identifying refactoring opportunities that enhance readability, structure, and maintainability without changing functional behavior.

The Prompt

Review the following code and suggest refactoring improvements focused on readability and maintainability.

Code:
{{code}}

Evaluate the code specifically on:

- Naming of variables, functions, and classes
- Function length and responsibility (Single Responsibility Principle)
- Code structure and logical flow
- Duplication and opportunities for abstraction
- Comment quality (missing, redundant, or misleading comments)
- Consistency in formatting and style

For each suggestion:
- Clearly explain why the change improves readability or maintainability
- Provide before/after code snippets where helpful
- Ensure behavior and output remain functionally identical unless explicitly stated

Guidelines:
- Avoid performance micro-optimizations unless they also improve clarity
- Focus on clean code principles over stylistic preferences
- Prioritize practical, actionable improvements

Variables

Usage Tips

• Works best when code is reasonably self-contained (functions, classes, modules).
• You can extend this prompt by adding a “language” variable for stricter style rules.
• Ideal for code review workflows, onboarding, or learning clean code practices.
• Combine with a follow-up prompt for “apply all refactorings automatically.”
