Struct TaskTool 

pub struct TaskTool { /* private fields */ }

The built-in task tool, which also holds the delegation state.

Construct one and include it in the parent’s tool list to enable delegation. Each nested run gets a new TaskTool with depth + 1 and the child profile’s own subagents (for recursion).

Profile ownership

The parent’s tool list (other than this TaskTool) never flows into a child. The child gets exactly: the profile’s declared tools, plus a fresh child TaskTool when the profile declares its own subagents.

Implementations

impl TaskTool

pub fn new( provider: Arc<dyn ModelProvider>, parent_model: Model, parent_config: RunConfig, subagents: Vec<SubagentProfile>, options: SubagentOptions, cancel: CancellationToken, event_sink: Option<Arc<dyn EventSink>>, policy: Option<Arc<dyn ToolPolicy>>, ) -> Self

Construct the top-level task tool (depth 0).

Include the returned tool in the parent agent’s tool list to enable delegation to any of subagents.

fn definition(&self) -> ToolDefinition

The static definition (name/schema/description).

fn execute<'life0, 'async_trait>( &'life0 self, ctx: InvokeContext, input: Value, ) -> Pin<Box<dyn Future<Output = CoreResult<ToolResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute the tool with validated input.
