The original title is: "Event-driven architecture for multi-agent systems: Pub/Sub patterns with the Swarm event bus"

Short summary

The article argues multi-agent systems should use event-driven architecture instead of synchronous request-response, which causes blocking, deadlocks, and cascading failures. It demonstrates a Pub/Sub pattern using the Swarm event bus where Planner, Implementer, and Critic agents communicate via events without waiting on each other. Benchmarks show throughput jumping from 45 to 850 tasks per minute with event-driven coordination versus synchronous calls.

• •Synchronous multi-agent coordination causes 340% latency increase from I/O blocking
• •Pub/Sub event bus decouples agents—Planner emits tasks, Implementers consume async, Critic reacts to events
• •Event-driven throughput reached 850 tasks/min vs 45 tasks/min synchronous in production benchmarks
