Features

• Tab-based views: Activity (parsed stderr), Raw Stderr, JSON-RPC (parsed stdout), Raw Stdout
• Channel separation: stdout = JSON-RPC only; stderr = structured logs (see MCP milestone)
• Live streaming: StreamReader.ReadLineAsync() from Process.StandardOutput/Error
• ANSI color rendering in RichTextBox
• Filter/search: Real-time text filter
• Circular buffer: 10,000 lines max
• Log export: Save to .log file
• Pause/resume: Inspect past output without losing new data
• Multiple terminals: One per agent simultaneously
• Auto-open on error
