Subagent

As explained in Grokking AI Applications

A specialized agent that performs a delegated part of a larger task under the coordination of another agent.

A subagent is a specialized agent that handles one delegated part of a larger workflow. A higher-level coordinator chooses the appropriate subagent instead of concentrating every responsibility in one monolithic agent. section 5.5

A practical subagent structure separates responsibilities:

  • Give each subagent a narrow purpose and focused toolset. section 5.5
  • Let a coordinator route tasks to the subagent best suited to the domain. section 5.5
  • Compose subagents into a hierarchical system of autonomous collaborators. section 5.5

Customer-success routing

A customer-success coordinator delegates billing questions to a billing assistant, technical issues to a support agent, and information requests to a documentation retriever. section 5.5

How Grokking AI Applications covers it

How deep it goes
Explains roles, delegation, focused tools, and hierarchical composition, but defers detailed implementation to later treatment.
Examples
Uses customer-success, project-management, and compliance-review coordinators with domain-specific assistants.
What you can do after
Build modular agent workflows by assigning narrow responsibilities and composing subagents under a coordinator.
How it connects
Connects subagents with agents, tools, multiagent systems, coordinators, and hierarchical systems.
