Multi-Agent Systems: When One Agent Isn’t Enough

The intuition

If a problem requires different skills (research, coding, reviewing) or parallel work, splitting responsibilities into multiple agents can improve quality and speed.

When multi-agent is worth it

Parallel research and summarization
Separation of duties (generator vs reviewer)
Complex workflows with specialized tools

When it’s overkill

If a single agent can solve it with good tool use and memory, multi-agent adds overhead: coordination, latency, and failure modes.
