# Code Simplifier

Simplify and refine code for clarity, consistency, and maintainability while preserving all functionality. Focus on recently modified code unless instructed otherwise.

## What To Do

Analyze recently modified code and apply refinements that:

### 1. Preserve Functionality
Never change what the code does - only how it does it. All original features, outputs, and behaviors must remain intact.

### 2. Apply Project Standards
Follow the established coding standards from CLAUDE.md and AGENTS.md including:

- Use ES modules with proper import sorting and extensions
- Prefer `function` keyword over arrow functions
- Use explicit return type annotations for top-level functions
- Follow proper React component patterns with explicit Props types
- Use proper error handling patterns (avoid try/catch when possible)
- Maintain consistent naming conventions

### 3. Enhance Clarity
Simplify code structure by:

- Reducing unnecessary complexity and nesting
- Eliminating redundant code and abstractions
- Improving readability through clear variable and function names
- Consolidating related logic
- Removing unnecessary comments that describe obvious code
- **IMPORTANT:** Avoid nested ternary operators - prefer switch statements or if/else chains for multiple conditions
- Choose clarity over brevity - explicit code is often better than overly compact code

### 4. Maintain Balance
Avoid over-simplification that could:

- Reduce code clarity or maintainability
- Create overly clever solutions that are hard to understand
- Combine too many concerns into single functions or components
- Remove helpful abstractions that improve code organization
- Prioritize "fewer lines" over readability (e.g., nested ternaries, dense one-liners)
- Make the code harder to debug or extend

### 5. Focus Scope
Only refine code that has been recently modified or touched in the current session, unless explicitly instructed to review a broader scope.

## Refinement Process

1. Identify the recently modified code sections
2. Analyze for opportunities to improve elegance and consistency
3. Apply project-specific best practices and coding standards
4. Ensure all functionality remains unchanged
5. Verify the refined code is simpler and more maintainable
6. Document only significant changes that affect understanding

## When NOT to Simplify

- Working code that is already clear and maintainable
- Code where the "simplification" would make it harder to understand
- Third-party code or generated code
- Performance-critical code where the current structure is intentional
