Multi-Agent Systems

A multi-agent system is an architecture in which several specialized AI agents collaborate on a task, each handling a distinct role — for example, one researches, one drafts, one validates — and passing work between themselves.

Compared with a single general-purpose agent, specialization can improve output quality per step, but it introduces coordination problems: handoff errors, duplicated work and cascading failures when one agent's mistake propagates downstream.

A practical example

Example: a campaign workflow uses a research agent to gather account context, a writing agent to draft the email sequence and a compliance agent to check claims against approved messaging before anything reaches a human for final approval.

What to evaluate before investing

  • Ask how agents exchange context: shared memory, structured handoffs or free-text passing, and what gets lost at each handoff.
  • Test failure isolation: if one agent fails or returns poor output, does the pipeline stop or continue with degraded results?
  • Check observability: can you see each agent's input and output separately to locate where quality broke down?

Limitations and tradeoffs

More agents mean more moving parts; a well-tuned single agent often outperforms a poorly designed multi-agent chain on the same task.
