LLM Integration Module for Kotlin MCP Server
This module provides comprehensive AI/LLM integration capabilities for the MCP server.
As an MCP server called by AI assistants like GitHub Copilot, it leverages the calling
LLM to generate sophisticated, contextually relevant Kotlin/Android code.
Features:
- Dynamic code generation using the calling LLM
- Context-aware code completion and enhancement
- Intelligent code analysis and optimization suggestions
- AI-powered refactoring and modernization
- Smart documentation and comment generation
- Architecture pattern recommendations

## Generated Code Explanation
**Type**: {request.code_type.value}
**Class**: {request.class_name}
**Package**: {request.package_name}
### Key Features:
- Production-ready implementation with complete business logic
- Modern Android/Kotlin patterns and best practices
- Comprehensive error handling and validation
- Reactive state management (where applicable)
- Dependency injection with Hilt
- Accessibility and performance considerations
### Architecture Patterns Used:
- MVVM (Model-View-ViewModel) for UI components
- Repository pattern for data access
- Dependency injection for loose coupling
- Reactive programming with StateFlow/Flow
- Clean Architecture principles
### Code Quality Features:
- No TODO comments - complete implementations
- Proper exception handling and recovery
- Comprehensive documentation with KDoc
- Test-friendly design with interfaces
- Performance optimization considerations
