## Import Analysis
### Files with High Import Count (>10):
$(while read -r line; do
    file=$(echo "$line" | cut -d: -f1)
    count=$(echo "$line" | cut -d: -f2)
    if [ "$count" -gt 10 ]; then
        echo "- $file: $count imports"
    fi
done < "$IMPORT_COUNTS_FILE")

### Potentially Unused Imports:
$(cat "$PROJECT_ROOT/reports/performance/unused_imports.txt" 2>/dev/null || echo "None found")

## Circular Dependencies
### Detected Cycles:
$(while read -r line; do
    echo "- $line"
done < "$CIRCULAR_DEPS_FILE")

## Module Build Times
### Slowest Modules:
$(sort -t: -k2 -nr "$MODULE_BUILD_TIMES_FILE" | head -5 | while read -r line; do
    module=$(echo "$line" | cut -d: -f1)
    time=$(echo "$line" | cut -d: -f2)
    echo "- $module: ${time}s"
done)

## Summary
- Total Files: $TOTAL_FILES
- Build Duration: $((BUILD_END_TIME - BUILD_START_TIME))s
- Success Rate: $((SUCCESS_COUNT * 100 / TOTAL_FILES))%

## Performance Analysis
$(cat "$PROJECT_ROOT/reports/performance/optimization_report.md" 2>/dev/null || echo "No performance data available")

## Code Quality
$(cat "$PROJECT_ROOT/reports/code_quality/final_report.md" 2>/dev/null || echo "No code quality data available")

## Recommendations
1. Review files with high import counts
2. Address circular dependencies
3. Optimize slow building modules
