What's Wrong?

What happened
In a Claude Project with many threads, the Library (project files) builds up quickly with no good way to manage it. Threads drop screenshots, videos, markdown notes and uploaded attachments into it, often at the root with generic names, so after a few days I have around 190 files I can't make sense of.

There's no bulk select or bulk delete, and I can't delete a folder, so clearing it means removing files one at a time, with dangling folders that are undeletable.

When I asked Claude in the project chat to do the tidy for me, and approved the exact list of files, its session safety check blocked the bulk delete anyway, and I have no setting to allow it. A script on my own machine can't help either, because the Library lives in cloud storage. I'd like folder deletion, multi-select delete, and a way to approve Claude doing a bulk tidy (ideally with a preview of what will be removed). It would also help if a file showed which thread created it, so I can tell what's safe to remove.

Environment

• Filed from: Report a problem in Claude Code
• Project ID: chan_01W8Pi4nCxDYLq4jTdw4gVvR

What Should Happen?

1. Claude should be able to delete files from the library.
2. I should be able to multi-select and delete files, right now it shows it as an option, but does nothing.
