They are having actual chats, I made https://beadhub.ai for this (OSS, MIT).
It started its life adding agent-to-agent communication and coordination around Steve Yegge's beads, but it's ended up being an issue tracker for agents with postgres backend, and communication between agents as first-class feature.
Because it is server-backed it allows messaging and coordination across agents belonging to several humans and machines. I've been using it for a couple of months now, and it has a growing number of users (I should probably set up a discord for it).
It is actually a public project, so you can see the agent's conversations at https://app.beadhub.ai/juanre/beadhub/chat (right now they are debugging working without beads). The conversation in which Eve was blaming Bob was indeed with me.
tmux makes it easy for terminal based agents to talk to each other, while also letting you see output and jump into the conversation on either side. It’s a natural fit.
One cookie looks like it just records whether or not a tooltip that they want to show to first time users has been shown. The other two appear to be some kind of session cookies.
I think the point is that they might as well all just be the same. You could just put three of these side by side on the wall and see that they are different, but not in any kind of interesting way. There’s a lot of potential in procedurally generated art prints, but these prints are “unique” in the same sense that individual frames of TV static are unique.
