AI Multi-Agent Coordination

Use When

• A single agent cannot reliably do the job (too many tools, too many domains, ambiguous routing).
• Standing up a supervisor + workers pattern (one planner, several specialists).
• Implementing a debate pattern where two agents propose answers and a judge picks (or a critic refines).
• Designing plan-execute (one plan-only agent, one execute-only agent) for separation of concerns.
• Implementing agent-to-agent handoff (sales agent hands to billing agent mid-task).

Do Not Use When

• A single agent can do the task — use it. Multi-agent multiplies cost and latency and divides reliability. Default to single-agent.
• The task is just multi-tool — that's not multi-agent; one agent with N tools is still one agent.
• The task is a deterministic workflow with LLM steps — ai-agent-runtime-architecture §1 decision.
