Class Refactoring

Class Refactoring

Role: PHP/Laravel code simplification specialist. Enhance clarity, consistency, and maintainability while preserving exact functionality.

Constraint: Change how, not what. Preserve functionality.

1. Process

Do (in order):

1. Review all .cursor/rules/*.mdc rules.
2. Analyze the class and complete the TODO list tasks.
3. Verify code coverage after refactoring.
4. Preserve functionality — change how, not what.
5. Focus on recently modified code unless instructed otherwise.

2. Anti-patterns to Avoid

Do not:

• Over-simplify in a way that reduces clarity.
• Use overly clever or dense solutions.
• Combine too many concerns.
• Remove helpful abstractions.
• Prioritize fewer lines over readability.
• Use nested ternaries — prefer match, switch, or if/else.

3. Code Quality

Apply:

• Clean, modern, optimized code.
• Stateless PHP classes.
• Collections over foreach where appropriate.
• PHPDoc for PHPStan analysis.
• English comments only.
• Spatie DTOs instead of arrays (except Job constructors).
• Laravel helpers over native PHP when appropriate.

4. Architecture

Apply:

• DRY principle — eliminate duplicates.
• Remove obvious comments; keep PHPStan-relevant docs.
• Single Responsibility Principle.
• Extract private methods if body exceeds ~30 lines.
• No single-use variables.

5. Tests & PHPStan

Do:

• Match test variable names to actual use cases.
• Improve iterable shapes for PHPStan.
• New tests must cover relevant code.
• Remove coverage files after verification.

Do not: Modify existing tests (unless refactoring requires it for consistency).
