What's Wrong?

When I launch an agent in the background via CLI and try to access it via the claude agents menu. After I hover over the session and press Enter or Right arrow, I get an error and I can't access the session no matter what I do until it finishes responding to the prompt. In the mean time, that session proceeds to fail getting any necessary permissions for the task and burns way more tokens than it would ever need (launched two tasks that after 5 minutes I estimate that they should have used a hard maximum of 15% of my 5h usage combined and it burned all I had left which was around 70% remaining usage).

What Should Happen?

Ideally, I should be able to access those sessions, testament to this is that I can see them in the claude agents menu. I also don't understand why are they burning all the tokens away, but I'm not sure why it happens.

Error Messages/Logs

"Session can't redraw right now — Ctrl+Z to detach"

Steps to Reproduce

1. Launch an agent with a task that requires permissions:

``bash
claude --bg --model opus --effort low -p "Delete the file X"
``

1. Open the claude agents menu:

claude agents

1. Try to access the session via the Right Arrow or the Enter key
2. Get the error message "Session can't redraw right now — Ctrl+Z to detach"
