Subagent
Agent spawned by an agent
A secondary agent instance spun up by a parent agent for a subtask — research one file, run tests in isolation, or explore a hypothesis — then return results upstream.
Concrete example
The main agent delegates “map every API route” to a subagent while it edits the handler.
Why it matters
How multi-agent systems scale work — and complexity.
