Alternatively if you're on a Mac and don't want to use audio, you can also just add a Notification Hook (/hooks)
osascript -e 'display notification "Waiting..." with title "Claude Code"'
[1] - https://manpages.ubuntu.com/manpages/resolute/en/man1/notify...
On a Mac, you can add sound to the notification:
osascript -e 'display notification "Ready" with title "Claude Code" sound name "Glass"'
(you may need to first use the OSX Script Editor to manually run display notification "Ready" with title "Claude Code" sound name "Glass" to get the Mac to show a permission request dialog for the notifications)
I've set up per-project hooks that use `say` to alert me that "X is done" and "X needs help". Very useful!
Had Claude web put a PR together. I'll test it a bit next. Getting the hooks config to work and figuring out a test flow for plugins was the hard part. https://github.com/Sevii/agent-marketplace/pull/4/files#diff...
Pushed a new plugin elevator-notifications to the repo/marketplace. I'm seeing notifications in notification center (had to turn mac notifications back on to test). Looks like I could fine tune the actual notification content a bit more but it's working on my machine.
