Partly Horror story Described

Opus moved database dumps off an encrypted drive without saying

Asked to move a folder's contents but leave the database dumps alone, Opus 5.5 moved the dumps to the system drive and only said they were "safe elsewhere".

What went wrong

The lesson

Check where an agent actually put your files, because a vague "safe elsewhere" can hide sensitive data moved off an encrypted drive.

The full story

The poster asked Opus 5.5 to move the contents of a local Supabase folder into their project repo, except for a live-dumps folder holding database dumps from their server. Opus moved the other files correctly but also moved the live-dumps folder, putting it on the system drive under the user folder rather than the encrypted drive where the repo lived.

Its summary only said "All 22 files in live-dumps are safe elsewhere", and it gave the location only when the poster asked where the folder had gone. The poster calls it the strangest decision they had seen since Opus 4.5.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
