A desktop application with a multi-terminal dashboard for managing and monitoring Kiro CLI sessions with support for both interactive and non-interactive modes.

⚠️ IMPORTANT: Before using PARK, you must have:

• Kiro CLI installed and configured on your system
• Kiro CLI authenticated and logged in (run kiro-cli configure if needed)
• Verify by running kiro-cli --version in your terminal

PARK launches Kiro CLI sessions - it does not include or install Kiro CLI itself.

PARK is packaged as an Electron desktop app that provides:

• Native desktop application for macOS (with Windows/Linux support planned)
• Multi-terminal dashboard for managing Kiro CLI sessions
• Launch and manage multiple Kiro CLI sessions simultaneously
• Save session configurations for reuse
• Monitor session status in real-time
• View terminal output in an integrated interface
• Support both interactive chat and non-interactive command execution

npm run dev    # Development with auto-reload

Interactive PTY (interactive-pty):

• Uses node-pty to spawn pseudo-terminal
• Full terminal emulation with ANSI escape codes
• Supports terminal resize
• Bidirectional I/O streaming
• Use case: kiro-cli chat interactive sessions

Non-Interactive Process (non-interactive):

• Uses Node.js child_process.spawn
• Captures stdout/stderr
• No terminal emulation
• Use case: kiro-cli chat --no-interactive with prompt file

• Session Creation: ~100ms (PTY spawn time)
• WebSocket Latency: <10ms (local)
• Database Operations: <5ms (SQLite)
• Concurrent Sessions: 50-100 (system resource dependent)
• Output Buffer: 1000 lines per session
• Max Selected Sessions: 5 (for batch operations)

1. File System Access: Limited to configured directories
2. Process Isolation: Each session runs in separate process
3. WebSocket Validation: Session ID checked before attachment
4. File Upload Limits: 10MB max file size
5. Path Validation: Uploaded files restricted to uploads directory

Backend won't start:

• Check if port 3000 is available
• Verify Node.js version (18+)
• Check ~/.park-agent-launcher/ directory permissions

Frontend can't connect:

• Ensure backend is running on port 3000
• Check browser console for errors
• Verify WebSocket connection in Network tab

Session shows as stopped but process is running:

• Backend was restarted while session was active
• PID tracking lost - rerun the session

Terminal not displaying output:

• Check WebSocket connection status
• Verify session is in 'active' state
• Check backend logs for errors
