Module subagent 

Subagent support for spawning child agents.

This module provides the ability to spawn subagents from within an agent. Subagents are isolated agent instances that run to completion and return only their final response to the parent agent.

Overview

Subagents are useful for:

• Delegating complex subtasks to specialized agents
• Running parallel investigations
• Isolating context for specific operations

Example

use agent_sdk::subagent::{SubagentTool, SubagentConfig};

let config = SubagentConfig::new("researcher")
    .with_system_prompt("You are a research specialist...")
    .with_max_turns(10);

let tool = SubagentTool::new(config, provider, tools);
registry.register(tool);

Behavior

When a subagent runs:

1. A new isolated thread is created
2. The subagent runs until completion or max turns
3. Only the final text response is returned to the parent
4. The parent does not see the subagent’s intermediate tool calls
