What issue are you seeing?

I entered a long prompt when using the /goal feature and got this:
Failed to set thread goal: thread/goal/set failed in TUI

I lost the whole prompt which I spent 20 minutes crafting which is incredibly frustrating. It is not persisted in my sessions, nor captured as an event etc...

This is not a bug but a UX issue. Even if there is a character limit for the /goal command, a better UX would be to print the prompt onto the screen before throwing the error.
alternatively, show something if the character limit is reached.

What steps can reproduce the bug?

/goal [some decently long prompt]

What is the expected behavior?

prompt is persisted and printed to the screen before surfacing the error.

or show something when the character limit is reached.
