Control flow from main agent to subagent and back to main agent #2686
Description
Hey,
I have a main agent
and a bunch of sub agents (one in the example)
I use the main agent as an orchestrator, and the subagent as a specialized agent which does the atomic task. The prompts define control flow from main agent to sub agent and again back to main agent (as handover).
We see that when the main agent hands over to subagent, which might ask a user input, to accomplish its task, somehow the main agent starts over all again, this this goes into an endless loop.
Pretty confused why this is happening and how to fix this. Any help here please?

shouldn't the
descriptionof the main agent be apromptinstead?rekram1-node commentedon Sep 19, 2025
just to note:
description: used so a primary agent can designate tasks to the given agent (this is basically a prompt for the main agent to know if it should call this agent or not)
prompt: this is the prompt the agent is being given

its the same #2378
Now work with subagents almost impossible because thea are implemented just as prototype: some part of work can be delegated and that's all. You can't control anything:
Spoiler: all these points are not fantastic, already implemented in ClaudeCode and it's the reason why I switched to it.
Now Opencode subagents can just receive prompt for the subtask and return some result.

You can navigate to the child session and communicate with the subagent directly actuallybut we definitely need to make that permissions feedback betteredit: my bad mistake

All messages sent to subagents are actually sent to main agent

@NaikSoftware you're right! I missed that thanks for calling out.
I raised with the team that some of the UX for subagents isn't quite as good as CC as you have called out. Thanks for the continuous feedback here
