Refactoring Workflow

// Original: 150-line processOrder function

// Claude's approach: Extract small, focused methods
class OrderProcessor {
  processOrder(order: Order) {
    this.validateOrder(order);
    this.calculateTotal(order);
    this.applyDiscounts(order);
    this.processPayment(order);
    this.updateInventory(order);
    this.sendConfirmation(order);
  }

  private validateOrder(order: Order) { /* ... */ }
  private calculateTotal(order: Order) { /* ... */ }
  // etc.
}

// Gemini's approach: Functional pipeline
const processOrder = pipe(
  validateOrder,
  calculateTotal,
  applyDiscounts,
  processPayment,
  updateInventory,
  sendConfirmation
);

// Cursor's approach: Strategy objects
class OrderProcessor {
  constructor(
    private validator: OrderValidator,
    private calculator: PriceCalculator,
    private payment: PaymentProcessor,
    private inventory: InventoryManager,
    private notifications: NotificationService
  ) {}

  processOrder(order: Order) {
    this.validator.validate(order);
    const total = this.calculator.calculate(order);
    this.payment.process(order, total);
    this.inventory.update(order);
    this.notifications.sendConfirmation(order);
  }
}
