Need to disable Agent Tool Parallel Behaviour

[AravindR-1]

Sub‑agents in ADK are currently not functioning efficiently. The main issue is that sub‑agents are unable to return their output back to the manager/orchestrator—instead, they respond directly to the end user. As a workaround, I converted the agent into a tool, which works better for now.

However, in certain scenarios I need to disable parallel execution for tools. This option is currently not supported for AgentTool.

Request
Please add support for disabling parallel execution in AgentTool.

Thanks for reporting. We often get confusions between sub agents and agent tools. sub agents is used when the trask is TRANSFERED while agent tools work like tools. Hence the behavioral diffrerence. I will ask the team to take a look at the parallel execution in agentTool.
