What's Wrong?

When starting claude in agents view I cannot choose the mode for a new agent, cycling (e.g. via shift+tab) does not work.

What Should Happen?

While in the parent view it should be possible to cycle mode to choose what the new agent is going to do.
For example I want agent to plan first so I review its output. But when I type something and press enter which starts a new session, it automatically drops into the "auto mode" and starts doing things.

Alternatively perhaps typing /plan [what to do] would start a new session in the plan mode.

Steps to Reproduce

Open claude agents.
Try cycling modes, see that it's not possible to choose a mode for a new session / agent.
