A hub-and-spoke agent puts a single orchestrator at the centre. It holds the task context, decomposes the request, and dispatches sub-tasks to specialist sub-agents arranged around it, then aggregates their returns into one answer. The specialists never talk to each other; every decision and every write routes back through the hub. In anatomy terms the hub is the reasoning core, and each spoke is a scoped effector or sub-agent bound to a single capability. It is the most common production shape because it keeps control, cost and auditing in one place, at the price of everything depending on the centre.

## In the anatomy

The hub is the reasoning core; the spokes are specialist sub-agents or effectors bound to one capability each; the policy perimeter wraps the hub's dispatch path, so every write is gated in one place.
