What's Wrong?

When I choose the Effort max and start the conversation with it, then at some point I need to do /exit to do something then get back to do /resume, it says this:

<img width="1920" height="173" alt="Image" src="https://github.com/user-attachments/assets/d451c525-25f6-46b7-8cf2-95569dfc7545" />

Just before i explain I need to clarify something, which is that my default effort is "xhigh".

So it says that using another effort level will be slower and use more tokens, while this session in specfic was using the Max Effort!

What Should Happen?

Claude should at least save the converstaion/session effort.

I am not very sure this is a the solution, but you may try to find the best solution, I trust you.
