Problem

On Windows, a terminal/console window pops up and closes on every hook execution (every message). This is extremely disruptive to the user experience.

Symptoms

Black console window flashes on every Claude message
Happens when realtime hooks are enabled
Multiple reports across different Windows versions

Expected Behavior

Hooks should execute silently in background
No visible windows during normal operation

Possible Causes

Node.js spawn without windowsHide: true
Missing detached option on child processes
Console allocation for stdio

Suggested Fixes

// When spawning processes on Windows
spawn(command, args, {
  windowsHide: true,
  detached: true,
  stdio: 'ignore'  // or pipe if output needed
});

Environment

Windows 10/11
Various Node.js versions
