Multi-Agent System
Several specialised agents working together, usually with a coordinator dividing the work.
Multi-agent setups split a job across agents with narrow roles — research, draft, critique — on the theory that focused context beats one agent juggling everything. They genuinely help on tasks that decompose cleanly. They also multiply cost, latency, and failure modes, so reach for one only after a single agent has demonstrably failed.
In practice: One agent gathers sources, a second writes, a third fact-checks against the sources.
