# SE-Agent Code Evolution for Retail Inventory System

## Initial Code Analysis
The provided inventory management system for [COMPANY] in the retail sector has several areas for improvement:
- Lack of input validation
- Inefficient database queries
- No error handling for API calls

## Revision Phase
```python
# Added input validation and error handling
try:
    if not isinstance(product_id, int) or product_id <= 0:
        raise ValueError("Invalid product ID")
    # ... rest of the code
except ValueError as e:
    print(f"Error: {e}")
```

## Recombination Phase
```python
# Combined inventory check and order processing into a single transaction
def process_order(product_id, quantity):
    # Check inventory
    # Process order if available
    # Update inventory
```

## Refinement Phase
```python
# Optimized database queries using prepared statements
cursor.execute("""
    SELECT * FROM inventory
    WHERE product_id = %s AND quantity >= %s
    FOR UPDATE
""", (product_id, quantity))
```
