Implementation

  final parsed = SubagentInput.fromJson(input);
  if (spawner != null) return spawner!(parsed);

  // Stub: real implementation would spawn an agent session.
  final agentId = '${parsed.name}_${DateTime.now().millisecondsSinceEpoch}';
  return ToolResult.success(
    'Sub-agent "$agentId" created with role "${parsed.role}". '
    'Task queued: ${parsed.task}',
