Thanks for reporting this. You’re right, this is a confirmed bug. The new Agent Window’s @ picker currently handles folder discovery differently from the old side chat, which means many folders don’t surface when you type their name after @.

Our team is aware of this regression and is working on a fix to bring the folder mention behavior in line with how it worked previously.

In the meantime, if you type just @ with no text after it, workspace root folders should still appear in the dropdown, though this doesn’t help with deeper subdirectories.
