What's Wrong?

In case of "You've reached your Fable 5 limit. Run /usage-credits to continue or switch models with /model.", the session cannot be closed in a way that allows you to continue with a cheaper model in a new session. Due to the forced model switch, the AI agent has to re-read the entire session, wasting a lot of tokens unnecessarily. It is not clear how much of Fable's recent work is lost, but it seems to me that it is a lot. I ask for a fix for this error and I would like to point out that I am not happy about my wasted tokens.

Clean session closure offer is also missing when the 5-hour and weekly limits are exceeded. This should be available even though there are no tokens left to be used at that time.

What Should Happen?

When the limit of a 5 hours or a weekly token or model usage is reached, Claude Code should offer to close the current session cleanly, allowing it to continue in a clean session with a different model or even manually.
Such session closing should not cost more tokens.
