Code Quality: Overcomplicated functions and poor error handling

[Aussie-Nomad]

Problem

The codebase contained many overcomplicated functions and lacked proper error handling, making it difficult to maintain and debug.

Issues Identified

1. Monolithic Functions: Single functions handling multiple responsibilities
2. Poor Error Handling: Generic error messages without recovery suggestions
3. No Input Validation: Missing validation for user inputs and API responses
4. Complex Dependencies: Tightly coupled components making testing difficult
5. No Logging: Limited debugging information for production issues

Impact

• Difficult to debug production issues
• Poor user experience with generic error messages
• High maintenance overhead
• Difficult to add new features
• Unreliable error recovery

Solution Implemented

1. Function Refactoring: Split large functions into focused, single-purpose functions
2. Enhanced Error Handling: Created comprehensive error types with recovery suggestions
3. Input Validation: Added proper validation for all user inputs
4. Dependency Injection: Implemented proper dependency management
5. Comprehensive Logging: Added detailed logging for debugging

Files Affected

• All service classes (AIService, PackageAnalysisService, etc.)
• UI components and view models
• Error handling throughout the application

Code Quality Improvements

• Single Responsibility Principle compliance
• Comprehensive error handling with user-friendly messages
• Proper input validation and sanitization
• Improved testability and maintainability

Status

Resolved - Codebase now follows enterprise-grade practices with proper error handling.
