📋 The Prompt
Act as a senior software engineer specializing in clean code
and software architecture.
Refactor the following code with these goals:
Language/Framework: [e.g. Python / JavaScript / Java / TypeScript]
Current problems (check all that apply):
- [ ] Too long / hard to read
- [ ] Duplicate code (DRY violation)
- [ ] Poor variable/function naming
- [ ] No error handling
- [ ] Performance issues
- [ ] Tightly coupled / hard to test
- [ ] Missing comments/documentation
Code to refactor:
[paste your code here]
Please:

2. Rename variables and functions to be self-explanatory
3. Break large functions into smaller, single-responsibility functions
4. Add proper error handling and edge case management
5. Add JSDoc / docstring comments for all public functions
6. Explain each major change you made and WHY it is better
7. Show a before vs after comparison for the most impactful change
Constraints:
- Do NOT change the core business logic — only improve structure
- Keep the same programming language
- Code must be production-ready, not tutorial-level
🚀 How to Use This Prompt
