## Optimization Strategy
### Three-Tier Classification System
1. **Small Arrays** (≤100 elements): Return full data
- Maintains backward compatibility
- Minimal token impact
2. **Medium Arrays** (101-10,000 elements): Return statistical summary
- Dimensions and element count
- Statistical measures (min, max, mean)
- Sample data preview (5+ elements)
- Memory usage information
3. **Large Arrays** (>10,000 elements): Return metadata only
- Dimensions and element count
- Statistical measures (min, max, mean)
- Minimal sample preview (3 elements)
- Memory usage and compression note
### Configurable Thresholds
The system supports configurable compression levels:
**Aggressive Configuration:**
- Small threshold: 10 elements
- Medium threshold: 100 elements
- Preview elements: 2
- Result: 382 bytes for 40K element array
**Conservative Configuration:**
- Small threshold: 1,000 elements
- Medium threshold: 50,000 elements
- Preview elements: 10
- Result: 506 bytes for 40K element array
