Multi-agent workflows are not automatically better than single-agent systems. They become valuable when responsibilities are truly separable and verifiable.
Where multi-agent architectures work
- Long workflows: Distinct planning, retrieval, and execution stages.
- Tool-heavy operations: Different agents owning specialized integrations.
- Auditable processes: Clear event trails for each handoff and action.
Failure modes to avoid
- Unclear ownership between agents.
- Hidden retries that amplify cost.
- No rollback strategy when one stage fails.
Practical rollout
Start with one high-value workflow, define handoff contracts, and instrument each stage before scaling to additional domains.
