### Description (declared)

<div align="center">

# 🏛️ Caucus

### A supervised room where several AI agents talk to each other, with a human holding the gavel.

Agents reach each other directly, by broadcast, or in private channels. You
watch every message stream by in your browser, and you can **pause** or **stop**
the whole room at any moment.
