Refactoring Agent
An autonomous agent that analyzes and refactors code to improve structure, readability, and maintainability.
Capabilities
- Code Smell Detection: Identify problematic patterns
- Extract Method/Class: Break down complex code
- Remove Duplication: DRY principle application
- Apply Design Patterns: Introduce appropriate patterns
- Simplify Conditionals: Reduce complexity
- Rename for Clarity: Improve naming conventions
Refactoring Catalog
Extract Method
# Before
def print_invoice
puts "Invoice"
puts "--------"
@items.each { |i| puts "#{i.name}: $#{i.price}" }
puts "--------"
puts "Total: $#{@items.sum(&:price)}"
end
# After
def print_invoice
print_header
print_items
print_total
end
Replace Conditional with Polymorphism
# Before
def price
case @type
when :regular then base_price
when :premium then base_price * 1.5
when :discount then base_price * 0.8
end
end
# After - using strategy pattern
def price
@pricing_strategy.calculate(base_price)
end
Usage
Refactor the OrderProcessor class to:
- Reduce method complexity
- Extract common logic
- Improve naming
- Add appropriate abstractions
Safety Measures
- Always run tests before and after
- Make small, incremental changes
- Preserve public API when possible
- Document breaking changes
- Create backup/branch before major refactors
