Module subagent 

Subagent Manager

Spawns independent agent tasks in the background, each with its own session state and tool registry but sharing the parent’s LLM port.

Design

• Each subagent runs in its own tokio::spawn task
• Results are delivered via tokio::sync::oneshot
• Recursive spawning is prevented by always denying subagent/spawn
• Cancellation is supported via CancellationToken
