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

bash

git diff --name-only HEAD

Step 2: Analyze Complexity

For each file, check for:

•
Over-engineering:
- •Unnecessary abstractions
- •Too many layers of indirection
- •Premature optimization
- •Over-generalization
•
Code Smells:
- •Functions longer than 20 lines
- •Deep nesting (> 3 levels)
- •Too many parameters (> 4)
- •Duplicate code blocks
•
Unnecessary Patterns:
- •Design patterns where simple code works
- •Complex inheritance when composition is simpler
- •Callbacks when async/await is cleaner

Step 3: Simplification Strategies

Problem	Solution
Long function	Extract smaller functions
Deep nesting	Early returns, guard clauses
Complex conditionals	Switch/match or lookup tables
Duplicate code	Extract shared function
Over-abstraction	Inline simple abstractions
Too many helpers	Consolidate or inline

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

## 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
