# Agent Booster Migration Report

## Summary
- **Total Edits**: ${stats.totalEdits}
- **Agent Booster Edits**: ${stats.boosterEdits} (${stats.boosterAdoptionRate})
- **Traditional Edits**: ${stats.traditionalEdits}
- **Average Speedup**: ${stats.avgSpeedupFactor}x
- **Total Time Saved**: ${(stats.totalSavingsMs / 1000).toFixed(2)}s
- **Monthly Cost Savings**: $${stats.monthlySavings}

## Performance Comparison

| Method | Average Latency | Speedup |
|--------|-----------------|---------|
| Agent Booster | ~1ms | 352x |
| Traditional | ~352ms | 1x |

## ROI Analysis

- **Implementation Cost**: $0 (open source)
- **Monthly Savings**: $${stats.monthlySavings}
- **Annual Savings**: $${(parseFloat(stats.monthlySavings) * 12).toFixed(2)}
- **Payback Period**: Immediate

## Recommendation

✅ **APPROVED**: Agent Booster provides 352x speedup with immediate ROI.
- Deploy to all code editing operations
- Enable fallback for unsupported languages
- Monitor performance metrics
