Getting Up to Speed on Multi-Agent Systems, Part 5: Debate, State, and Coordination

If wave 1 was about role-playing and the agentic coding turn was about interface quality, there’s a parallel thread running through the field asking a more fundamental question: what should multiple agents actually do with each other? Debate? Share state? Coordinate? And are any of these interchangeable? This post is about four papers that sit at that intersection, including one that isn’t really an LLM paper at all but is the clearest theoretical bridge from distributed systems into multi-agent AI.
