What issue are you seeing?

When the subagent is waiting for an instruction or for a question to be answered, the user is not always clearly notified in the main thread. However, after opening the subagent thread for the first time and then returning to the main thread, the question starts appearing there, in the main thread, for subsequent interactions.

Sometimes, you may wait for a long time thinking the subagent is still running, while the required-review notification is not clear enough in the first time.

I ran a brief example:

Main thread
<img width="447" height="911" alt="Image" src="https://github.com/user-attachments/assets/46650a15-c103-45c8-86b3-63f0215e9b00" />

Subagent thread
<img width="447" height="911" alt="Image" src="https://github.com/user-attachments/assets/d7c8bb8d-beaa-47d8-89fe-d5ef3f9bc34a" />

What steps can reproduce the bug?

Start a thread asking the agent to spawn a subagent with instructions to run a command that will likely require your review. Example: docker ps.

What is the expected behavior?

There are a few ways to make the notification clearer:

• Always expand the subagent details wrapper attached to the composer.
• Always show the question in the main thread, with clear information about which subagent is asking it. When multiple subagents require input, this could be shown as a multi-step question flow.
