TFE: Command for Claude Code

Analyze TFE Performance

You are analyzing the performance of TFE to identify bottlenecks and optimization opportunities.

Your Task

Use Desktop Commander and analysis tools to:

1. Profile the codebase

   • Search for potential performance issues:
     • Unnecessary file reads in loops
     • Inefficient string operations
     • Missing caching
     • Redundant calculations

2. Analyze specific modules

   • file_operations.go: File loading efficiency
   • render_*.go: Rendering performance
   • update_*.go: Event handling efficiency
   • helpers.go: Utility function optimization

3. Look for common issues

   • O(n²) operations
   • Repeated file I/O
   • Unnecessary allocations
   • Missing early returns
   • Inefficient string concatenation

4. Run benchmarks (if they exist)

   • Execute go test -bench=.
   • Analyze benchmark results
   • Compare with previous runs

5. Memory profiling

   • Look for potential memory leaks
   • Check for large allocations
   • Identify unnecessary copies

6. Suggest optimizations

   • Prioritize by impact (high/medium/low)
   • Provide code examples for fixes
   • Estimate performance improvement
   • List any trade-offs

🔍 TFE Performance Analysis

📊 High Priority Issues:
  1. loadFiles() reads directory twice - file_operations.go:123
     • Impact: 2x slower directory loading
     • Fix: Cache results in model
     • Estimated improvement: 50% faster

  2. renderPreview() rebuilds styles every frame - render_preview.go:89
     • Impact: Unnecessary CPU usage
     • Fix: Move styles to global constants
     • Estimated improvement: 20% faster rendering

📊 Medium Priority Issues:
  ...

💡 Quick Wins:
  - Add early return in getCurrentFile() if cursor out of bounds
  - Cache getFileIcon() results
  - Use strings.Builder instead of += in formatFileSize()
