Single-Agent vs Multi-Agent Systems

Single-agent

• One agent handles all tasks end to end.
• Simpler architecture and easier debugging.
• Good for moderate complexity workflows.

Multi-agent

• Multiple specialized agents collaborate.
• Useful for complex pipelines: planner, researcher, reviewer.
• Needs orchestration and clear handoff contracts.

Decision guide

Start with single-agent. Move to multi-agent when tasks have clear specialization and scaling needs.
