Supervisor Agent

Software componentOrchestrationOrchestration & Toolsarc:SupervisorAgent

An agent that plans tasks for, and assigns tools and subtasks to, specialised worker agents in a hierarchical architecture.

Responsibility. Decomposes goals and delegates subtasks to worker agents.

Also known as: Supervisor, Master agent, Manager Agent, Orchestrator Agent, TicketOrchestrator, Senior Orchestrator, Domain Orchestrator, Orchestrator agent, Manager agent (CrewAI hierarchical process), Manager agent, Editorial manager, Hierarchical process manager, Controller agent, Router agent, Coordinator agent, CoordinatorAgent, Meta-agent

Variant of Multi-Agent Coordinator abstract

When to choose. Choose when a workflow maps to an organizational team with clear role specialization and needs validation gates and iterative refinement until outputs meet quality standards. Avoid when agents need frequent ad-hoc back-and-forth interaction or when roles overlap or capabilities are vaguely defined.

Design guidance

SHOULD NOT be introduced unless multi-agent complexity is justified by genuine requirements.
SHOULD be used for well-defined sequential workflows where predictability outweighs scalability concerns.
MUST NOT be a single unreplicated instance in critical systems; a crashed central orchestrator halts the entire system.
SHOULD centralise error handling so every worker failure has an explicit fallback (retry, fallback queue, or escalation).
SHOULD be tiered into supervisors per sub-team (hierarchical) when a single orchestrator becomes a coordination bottleneck.
MAY expose standardised contracts to other autonomous domains (federated orchestration) instead of controlling their agents.
SHOULD include coordination logic so it does not overload any single worker pool.
SHOULD NOT be used to emulate iterative loops by repeatedly re-delegating the same task to the same agent; this makes delegation logic fragile.
SHOULD enforce explicit quality standards and re-delegate revisions to the appropriate specialist until they are met.
MUST be given precise role definitions and capability boundaries for its workers; overlapping or vague roles cause mis-delegation.
SHOULD use structured decomposition methods with preconditions instead of ad-hoc delegation rules.
SHOULD bound each agent's working memory by giving leaf agents raw inputs and parent agents only compressed results, accepting coordination overhead that grows with depth.

Quantitative guidance

As stated by the sources; verify before use.

N agents create N(N-1)/2 interaction pairs, making debugging prohibitively difficult (Ch1.2).
Centralized orchestration scales poorly beyond about a dozen worker agents (Ch1.3).
Ten-paper synthesis: leaf agents hold ~5,000 tokens and emit ~500-token summaries; middle layer holds ~5,000-10,000 tokens and passes ~2,000 tokens to the top agent (Ch5.9).
