# Get notified when Claude Code finishes a task

*July 26, 2025*

I've been using Claude Code lately, and I found myself wanting a simple way to know when Claude finished a task. Instead of watching the terminal, I figured a quick notification sound would do the trick. Luckily, Claude supports hooks, which are customizable actions that run when certain events occur. By editing the `settings.local.json` file in your project after init'ing, you can make Claude play a macOS system sound whenever a task completes.

Here's the hook configuration I added to my file:

```
{
  "permissions": {
    "allow": ["Bash(bin/rails runner:*)"],
    "deny": []
  },
  "hooks": {
    "Notification": [
      {
        "matcher": "",
        "hooks": [
          {
            "type": "command",
            "command": "afplay /System/Library/Sounds/Hero.aiff"
          }
        ]
      }
    ]
  }
}
```

This runs the afplay command to play the classic "Glass" sound that macOS ships with. It works every time Claude finishes running, giving me instant audible feedback that a process has ended. It also plays a different sound when Claude needs your attention. It's a small tweak, but it makes the workflow feel more complete and less like I'm waiting around for something to silently finish. Hope you enjoy this tip!
