Fields

agent_description: String

Description of what the sub-agent does

agent_display_name: String

Human-readable display name of the sub-agent

model: Option<String>

Model the sub-agent will run with, when known at start.

model_selection_source: Option<SubagentModelSelectionSource>

Authority or runtime mechanism responsible for sub-agent model selection, when known at start.

parent_id: Option<String>

resumable: Option<bool>

Whether this sub-agent can be resumed. Currently always false.

task_model_source: Option<SubagentTaskModelSource>

Where the model input for this sub-agent came from. Present when the task planner resolved the launch (the task tool and factory agents); absent for sub-agents created through other runtime paths.
