In short
Multi-agent systems generally adopt either hierarchical supervisor models (centralized router delegating sub-tasks to specialized worker agents) or peer choreography (agents communicating via shared event buses). Supervisor patterns provide superior observability, state governance, and deterministic recovery, while choreography excels in decoupled, asynchronous event processing.
Why single agents hit cognitive ceilings
Prompting a single LLM agent with dozens of disparate tools and conflicting system instructions leads to prompt bloat, high token costs, and frequent tool hallucination. Slicing complex domains into specialized agents, each with a narrow system prompt and tightly scoped tools, dramatically improves accuracy and execution speed.
The Hierarchical Supervisor pattern
In a supervisor architecture, an executive agent analyzes incoming user objectives, creates a structured dependency DAG, and dispatches sub-tasks to worker agents (e.g. a Research Agent, a Code Writer Agent, and a Security Auditor Agent). The supervisor aggregates intermediate outputs, evaluates completion quality, and maintains overall conversational context.
Peer choreography and event-driven multi-agent systems
In choreographed systems, agents do not report to a central controller; instead, they publish events to a shared message broker (like Kafka or RabbitMQ) and subscribe to relevant topics. When an agent completes its sub-task, its output event triggers the next agent in the ecosystem. This architecture offers high scalability but requires careful distributed tracing.
Preventing cascading errors and communication storms
In poorly designed multi-agent networks, an ambiguous output from one agent can trigger an exponential flurry of clarification messages and invalid downstream tasks. Explicit communication protocols, structured JSON message contracts, and strict hop-count limits prevent circular message storms.
Selecting the right pattern for enterprise workflows
For synchronous, high-governance business processes (such as loan underwriting, medical claims processing, or compliance verification), the hierarchical supervisor pattern is almost always preferable due to centralized auditing and deterministic error recovery.
