## System Architecture Overview

IFSandbox is a comprehensive framework for instruction fine-tuning, designed to enhance and evaluate instruction quality. The system is composed of three primary modules and a supporting utilities layer.

### 1. Enhancement Module (`modules/enhance/`)

The Enhancement Module is responsible for improving instruction quality through various constraints and modifications:

#### Dynamic Enhancement
- Analyzes instruction structure and content
- Identifies areas for improvement
- Applies appropriate enhancement strategies

#### Constraint Types
1. **Content Constraints**
   - Specificity requirements
   - Domain-specific terminology
   - Technical accuracy checks

2. **Situation Constraints**
   - Context-specific requirements
   - Use case scenarios
   - Environmental conditions

3. **Style Constraints**
   - Language consistency
   - Tone and formality
   - Cultural considerations

### 2. Evaluation Module (`modules/evaluation/`)

The Evaluation Module assesses instruction quality and effectiveness:

#### Testing Components
1. **Strict Testing**
   - Rule-based validation
   - Syntax checking
   - Format verification

2. **LLM-based Testing**
   - Semantic analysis
   - Coherence checking
   - Response quality assessment

3. **Difficulty Tagging**
   - Complexity analysis
   - Prerequisite knowledge assessment
   - Implementation difficulty scoring

### 3. Utils Module (`modules/utils/`)

The Utils Module provides essential support functions:

#### Core Utilities
1. **Checkpoint Management**
   - Progress tracking
   - State persistence
   - Recovery mechanisms

2. **File Operations**
   - JSON/JSONL handling
   - Pickle file management
   - Directory operations

3. **Text Processing**
   - Language detection
   - Pattern matching
   - String manipulation

## Workflow Process

1. **Input Phase**
   - Original instructions are collected
   - Initial validation is performed
   - Basic metadata is attached

2. **Enhancement Phase**
   - Instructions undergo dynamic enhancement
   - Constraints are applied systematically
   - Quality checks are performed

3. **Evaluation Phase**
   - Enhanced instructions are tested
   - Multiple evaluation methods are applied
   - Results are aggregated

4. **Output Phase**
   - Difficulty tags are assigned
   - Final validation is performed
   - Results are stored and documented

## Integration Points

- **API Integration**: Support for multiple LLM endpoints
- **Data Pipeline**: Efficient data flow between modules
- **Monitoring**: Comprehensive logging and tracking
- **Extension**: Plugin architecture for new features

## Performance Considerations

- Parallel processing for batch operations
- Caching mechanisms for frequent operations
- Resource management for large-scale processing

## Future Enhancements

1. **Automated Enhancement**
   - Self-learning enhancement strategies
   - Pattern recognition for common issues

2. **Advanced Evaluation**
   - Multi-model comparison
   - Cross-validation techniques

3. **Scalability**
   - Distributed processing support
   - Cloud integration capabilities
