Testing Interchangeability in LLM Agent Teams
This matters for production multi-agent systems. The result is that agents aren't fungible: swapping them increases communication overhead by 16 to 63 percent because agents develop implicit conventions with their partners. If you're deploying agent teams at scale, you need to account for training overhead and partnership stability, not just individual agent capability. The agent that sets agenda is especially hard to replace.
