A **Subagent** is another agent that is added as a capability to a "manager" agent. ### The Manager Pattern A high-level agent (e.g., "Customer Support Lead") can delegate complex tasks to specialized subagents (e.g., "Billing Specialist" or "Technical Troubleshooter"). ### Key Features * **Recursive Nature**: Subagents can themselves have their own subagents, allowing you to build deeply nested "Agent Trees." * **Shared Context**: Subagents inherit relevant context from their parents but operate within their own specialized prompts and capability sets. [State](/build/agents/agent_state) fields flow between them according to each field's read/write scope. * **Modular Design**: Build and test specialized agents independently, then compose them together into a powerful multi-agent system. ### Subagents and execution mode How a subagent is invoked depends on the parent's [execution mode](/build/agents/execution_mode): * In **`reasoning`** mode, the orchestrator delegates a scoped objective to the subagent inside the loop, then processes its result like any other action. * In **`route`** mode, a subagent can be the routing target, the original conversation is passed through, and the subagent's answer becomes the response. The subagent runs with its **own** execution mode, so a routing parent can delegate to a reasoning child and vice versa. For latency-sensitive deployments with deep hierarchies, the `high_performance` request flag flattens subagent capabilities into the root agent and runs everything in-process. See [Execution Mode, performance options](/build/agents/execution_mode#performance-options).
