Struct SpawnSubAgentTool 

pub struct SpawnSubAgentTool {
    pub work_dir: PathBuf,
    pub source_root: PathBuf,
    pub llm_client: Arc<dyn LlmClient>,
    pub event_tx: Option<UnboundedSender<AgentEvent>>,
    pub registry: Arc<SubAgentRegistry>,
    pub background_tx: Option<UnboundedSender<BackgroundResult>>,
}

Tool that lets the main agent spawn a subagent for a focused task.

The subagent runs in its own context window, does its work, and returns results to the caller. Subagents cannot spawn other subagents.

The agent can either reference a registered subagent by name, or provide an inline definition with a custom prompt and tool restrictions.

Fields

work_dir: PathBuf

source_root: PathBuf

llm_client: Arc<dyn LlmClient>

event_tx: Option<UnboundedSender<AgentEvent>>

registry: Arc<SubAgentRegistry>

background_tx: Option<UnboundedSender<BackgroundResult>>

When set, background subagent results are sent back through this channel so the parent agent loop can inject them into its conversation.
