/**
* Code Reduction Analysis:
*
* BEFORE: 98 lines of implementation code
* AFTER: 45 lines of business logic
* REDUCTION: 54% less code
*
* Eliminated:
* ✅ Manual error handling (12 lines)
* ✅ Parameter validation boilerplate (8 lines)
* ✅ Logging setup (6 lines)
* ✅ Response formatting (15 lines)
* ✅ Try-catch blocks (12 lines)
*
* Benefits:
* ✅ Consistent error handling with other tools
* ✅ Automatic parameter validation
* ✅ Standardized response format
* ✅ Built-in performance monitoring
* ✅ Easier to test and maintain
