Show HN: Claude Code Plugin to play music when waiting on user input

https://github.com/Sevii/agent-marketplace/blob/main/plugins/elevator-music/README.md
56•Sevii•1mo ago
Claude Code tends to be just slow enough you have time to tab away and get distracted. This plugin uses Claude Code's hooks to play music when Claude is waiting for user input so you don't just leave it sitting for 15 minutes.

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"'
You can probably do the equivalent using powershell in windows, and the notify-send [1] in linux.

[1] - https://manpages.ubuntu.com/manpages/resolute/en/man1/notify...

Sevii•1mo ago
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...
Sevii•1mo ago
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.
CharlesW•1mo ago
I've set up per-project hooks that use `say` to alert me that "X is done" and "X needs help". Very useful!
yodon•1mo ago
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)

Love this. I guess I need to build the happy Gilmore meme audio now. “Welllll?!!! We’re waiting!!”

I use Beads with Claude Code + Zed, and just brain dump to Claude to make a bunch of tasks with Beads, I have Claude ask me clarifying questions, then I let Claude go to town. Sometimes I let Claude work in parallel but APC seems to sometimes not like that not sure why.
d_sc•1mo ago
Can you use beads with other task management systems like linear or shortcut?

Also does beads work with obra’s superpowers plugin?

giancarlostoro•1mo ago
No idea, I know its open source and the LLM manages it directly. I tell Claude what to add etc and it does it.
ZeroConcerns•1mo ago
I sense a branding opportunity here... We already have "elevator music" to designate generic production-music-slop, so what will the next step be?

"OpenAI anything" seems a bit too much, yet "Claude somesuch" or "Grok horrifying" don't work either.

HN Branding Experts, what do you say?

Of course it’s vibe music!
craigds•1mo ago
this reminds me of one of my favourite features of Buildkite. When you're waiting on the outcome of a build you can click a button in Canvas mode and it'll play a tune to accompany the build. As soon as the build is done, the music stops.

is really well thought out - means I can turn the volume up and go do the dishes in the next room and be notified when I should return. Much more useful than a browser notification

onemoresoop•1mo ago
This is fun. A small cautionary tale from telecom history though. Once pleasant waiting exists, it quietly becomes acceptable waiting, then longer waiting, then a product requirement. Suddenly latency isn’t a bug, it’s an opportunity for vibes. Would hate to see 'AI thinking music' evolve into the modern equivalent of hold music designed less to soothe and more to make us tolerate delays that should’ve been fixed instead.
rollinDyno•1mo ago
Can we make it have access to the "Now Playing" MacOS feature that plays/pauses whatever I'm listening to? It could be a Youtube video, a track on Spotify or a video on VLC.
