Section 2

Multi-Agent Coordination Patterns

Section 1 established that specialization can help, that shared state needs a coordination protocol, and that communication topology is a real design decision. This section turns those foundations into three concrete, named production patterns: a supervisor that centrally routes work, a swarm that coordinates through local rules with no central authority, and a debate that reconciles independent answers into one better answer. Each pattern is a specific point on the same tradeoff curve Section 1 introduced, and each one fails in a specific, predictable way.
