  onIterationComplete: (iteration, metrics) => void;
  onOptimizationComplete: (result) => void;
  onError: (error) => void;
}
```

## 🚀 Usage

### Basic Example

```typescript
import { DSPyAgenticSynthTrainer } from './training/dspy-real-integration.js';

const trainer = new DSPyAgenticSynthTrainer({
  models: ['gpt-3.5-turbo'],
  optimizationRounds: 5,
  minQualityScore: 0.8
});

await trainer.initialize();

const result = await trainer.trainWithOptimization(schema, examples);

const data = await trainer.generateOptimizedData(100, schema);
```

### Advanced Configuration

```typescript
const trainer = new DSPyAgenticSynthTrainer({
  models: ['gpt-3.5-turbo', 'gpt-4', 'claude-3-sonnet-20240229'],
  optimizationRounds: 10,
  minQualityScore: 0.85,
  maxExamples: 100,
  batchSize: 20,
  evaluationMetrics: ['accuracy', 'coherence', 'relevance', 'diversity'],
  enableCaching: true,
  hooks: {
    onIterationComplete: (iter, metrics) => {
      console.log(`Iteration ${iter}: Score = ${metrics.overallScore}`);
    },
    onOptimizationComplete: (result) => {
      console.log(`Improvement: ${result.improvements.improvement}%`);
    }
  }
});
```

## 🔧 Technical Notes

### Import Path Issue

**Note**: The dspy.ts package (v2.1.1) has a build issue where the compiled files are at `dist/src/` instead of `dist/`.

Current workaround in code:
```typescript
import { ... } from '../node_modules/dspy.ts/dist/src/index.js';
```

This has been documented in the code and can be updated when the package is fixed.

### TypeScript Configuration

The integration uses:
- ES modules (ESM)
- TypeScript with strict type checking
- Full type safety where possible
- Runtime error handling for dynamic operations

### Dependencies

**Required:**
- dspy.ts@2.1.1 (already in package.json)
- zod@^4.1.12 (already in package.json)

**Runtime:**
- OpenAI API key for GPT models
- Anthropic API key for Claude models (optional)

## 🎯 Integration with Agentic-Synth

The integration extends agentic-synth's BaseGenerator pattern:

```typescript
import { BaseGenerator } from '../src/generators/base.js';
import { DSPyAgenticSynthTrainer } from './dspy-real-integration.js';

class OptimizedGenerator extends BaseGenerator {
  private trainer: DSPyAgenticSynthTrainer;

  async generateWithOptimization(options: GeneratorOptions) {
    // Use DSPy.ts for quality improvement
    const initial = await this.generate(options);
    const examples = this.convertToExamples(initial.data);

    await this.trainer.trainWithOptimization(options.schema, examples);
    return this.trainer.generateOptimizedData(options.count);
  }
}
```
