Agent Team

An agent team is a multi-agent setup organized around role-based collaboration — a lead agent plus specialized members like a planner, coder, reviewer, and tester — modeled loosely on how a human team divides work.

A lead agent coordinates role-based team members and assembles their results.

An agent team is a way of organizing a multi-agent system around recognizable roles rather than just arbitrary specialized agents. Instead of describing agents by what tools they have, an agent team describes them by the job they do in the workflow — a planner that breaks down the task, a coder that implements, a reviewer that checks the work, a tester that verifies it — echoing how a human software team is often organized.

A lead agent typically holds the overall goal and sequences the team members, similar to how a tech lead might assign and review work, though the specifics (who talks to whom, what gets shared) vary a lot between implementations. The 'team' framing is mostly a mental model for humans designing and debugging the system — under the hood it's still one main agent orchestrating several others.

The value of organizing agents this way is that each role can have a narrower, more reliable prompt and toolset — a reviewer agent's instructions can focus entirely on catching bugs and style issues rather than also having to know how to write new code — which tends to produce more consistent results than one generalist agent trying to do everything.

How it works

The diagram shows a lead agent coordinating four role-based members — planner, coder, reviewer, tester — with results flowing back to the lead in both directions, similar to agent-orchestration but organized specifically around human-team-like roles rather than generic tool or server integrations.

Example

An agent team building a small feature might have the planner agent turn a one-line request into a short list of concrete steps, the coder agent implement each step, the reviewer agent flag anything that looks wrong or inconsistent with the codebase's conventions, and the tester agent run and interpret the test suite before the lead reports the result as done.

How it differs

An agent team is a specific way of organizing a multi-agent-system — around human-team-like roles (planner, coder, reviewer, tester) — rather than a different concept altogether; not every multi-agent system is structured as a 'team,' some are organized purely by tool or domain specialization instead.

Common misconceptions

Often assumed: An agent team means the agents genuinely collaborate and negotiate like people.
Actually: Most agent teams are still one lead agent sequencing and assembling work from role-based members; the 'team' framing describes the roles, not independent peer negotiation.
Often assumed: More roles on the team always produces better results.
Actually: Each extra role adds coordination overhead and potential for miscommunication between agents; teams work best when each role maps to a genuinely distinct kind of work.

FAQ

What is an agent team in AI development?
It's a multi-agent setup organized around recognizable roles — like a planner, coder, reviewer, and tester — coordinated by a lead agent, loosely modeled on how a human team divides work.
Is an agent team different from a multi-agent system?
An agent team is a specific way of organizing a multi-agent system around human-team-like roles; not every multi-agent system uses that role structure.
Do the agents in an agent team talk directly to each other?
Usually not — most designs route coordination through a lead agent rather than having role-based agents communicate peer-to-peer.

Multi-Agent System

A multi-agent system is a setup where multiple AI agents, each with a narrower role, work on parts of a larger task and coordinate through some form of orchestration.

Agent Orchestration

Agent orchestration is the layer that decides which agent, subagent, tool, or server handles a given piece of work, in what order, and how their results get combined.

Subagent

A subagent is a secondary AI agent that a main agent spawns to handle a specific sub-task, usually with its own focused instructions and tools, and reports back to the agent that spawned it.
