+vt - VibeTunnel TTY Forward Wrapper
+
+USAGE:
+    vt [command] [args...]
+    vt --shell [args...]
+    vt -i [args...]
+    vt --no-shell-wrap [command] [args...]
+    vt -S [command] [args...]
+    vt --help
+
+DESCRIPTION:
+    This wrapper script allows VibeTunnel to see the output of commands by
+    forwarding TTY data through the vibetunnel utility. When you run commands
+    through 'vt', VibeTunnel can monitor and display the command's output
+    in real-time.
+
+    By default, commands are executed through your shell to resolve aliases,
+    functions, and builtins. Use --no-shell-wrap to execute commands directly.
+
+EXAMPLES:
+    vt top                  # Watch top with VibeTunnel monitoring
+    vt python script.py     # Run Python script with output forwarding
+    vt npm test             # Run tests with VibeTunnel visibility
+    vt --shell              # Launch current shell (equivalent to vt $SHELL)
+    vt -i                   # Launch current shell (short form)
+    vt -S ls -la            # List files without shell alias resolution
+
+OPTIONS:
+    --shell, -i            Launch current shell (equivalent to vt $SHELL)
+    --no-shell-wrap, -S    Execute command directly without shell wrapper
+    --help, -h             Show this help message and exit
+
+NOTE:
+    This script automatically uses the vibetunnel executable bundled with
+    VibeTunnel from the app bundle.
