My Claude projects accumulated data and documents so badly that after six days iterating, I had the same brief generated/uploaded four times, a trail of files ending in v8, v9, v10 where only the last one mattered, folders I attached by mistake, a parent folder and its own subfolder created and mounted, in a hierarchy I haven't specified. Context is what the model actually reads to make sense of my project, so all that noise made the answers worse over time and ate my knowledge and token budget.

Trying to clean it up was tedious. AND there is no remove button for folders (issue opened since March https://github.com/anthropics/claude-code/issues/40043). AND deleting documents is one at a time at root level, not possible within folders, with no undo.

So I built a small app and CLI to do just that. It also finds the duplicates and stale versions, shows what it'll do before it does it, and archives everything before deleting. Open Source, MIT, macOS only: [https://github.com/earsenio/cpcm](https://github.com/earsenio/cpcm)

It's vibecoded, so read it before pointing it at anything you care about. And it's a patch, not a fix. We still need real controls in the app.

*One tip even if you skip the tool: as discussed in this issue, editing spaces.json by hand isn't enough. A second file, remote-session-spaces.json, holds folder grants that get merged back in at session start. That's why a folder you deleted comes back.*
