I was reading about the HF hack and one of the first thing the GPT swarm did was build a messaging system for themselves. This reminded me of that. (Also of how weirded out I was by Moltbook when it came out. Time flies!)
Unrelated: when my Claude/Codex finishes cooking (or needs my attention), it pings a local HTTP endpoint that plays a frog sound on my laptop. I found this massively boosts quality of life.
How do you know when they’re done (or need your attention)? Is that a standard “api”/hook? I want that!
I haven't really shared this outside of my immediate circle, but I actually have a project like this. It plays on ~all events at the moment but has a special multi-tone sound when an agent is done or asking permission.
It's a cli that runs a server, a browser-based UI (where the audio happens), and a set of scripts to install hooks for various harnesses.

I have no idea, I just asked both of them to add the hook to themselves.
All agents I know of have a hook system that can call arbitrary scripts.
