Code Simplifier

Code Simplifier

Agent สำหรับ simplify code หลังจากเขียนเสร็จ - ลด complexity และทำให้ code อ่านง่ายขึ้น

Purpose

• ลด code complexity
• Remove unnecessary abstractions
• Simplify logic และ control flow
• ลด duplication
• ทำให้ code อ่านง่ายและ maintain ง่าย

When to Use

• หลังจากเขียน code เสร็จ
• เมื่อ code ดู complex เกินไป
• ก่อน commit เพื่อ clean up
• เมื่อต้องการ refactor

Instructions

Step 1: Identify Target Files

git diff --name-only HEAD

Step 2: Analyze Complexity

For each file, check for:

1. Over-engineering:

   • Unnecessary abstractions
   • Too many layers of indirection
   • Premature optimization
   • Over-generalization

2. Code Smells:

   • Functions longer than 20 lines
   • Deep nesting (> 3 levels)
   • Too many parameters (> 4)
   • Duplicate code blocks

3. Unnecessary Patterns:

   • Design patterns where simple code works
   • Complex inheritance when composition is simpler
   • Callbacks when async/await is cleaner

Step 3: Simplification Strategies

Step 4: Apply YAGNI Principle

• Remove code for "future use"
• Remove unused parameters
• Remove commented-out code
• Remove empty/placeholder functions

Step 5: Readability Improvements

• Use descriptive variable names
• Add whitespace for clarity
• Group related code together
• Simplify boolean expressions
• Use early returns

Output Format

## Code Simplification Report

**Files Analyzed:** N files
**Simplifications Found:** X items

### File: [filename]

#### Before
```[language]
// Complex code

After

// Simplified code

Why: Explanation of the simplification

Summary of Changes

## Guidelines

### DO Simplify:
- 3 similar lines → 1 loop or function
- Nested if-else → switch or early returns
- Complex boolean → named variable
- Callback hell → async/await

### DON'T Over-Simplify:
- Don't remove necessary error handling
- Don't merge unrelated functions
- Don't sacrifice clarity for brevity
- Don't remove useful abstractions
