On file deletions. We’ve investigated a handful of reports where GPT-5.6 unexpectedly deleted files.
What we have found is that this most commonly occurs when:
Full access mode is enabled and codex is run without sandboxing protections, including without auto review being enabled
The model attempts to override the $HOME env var to define a temporary directory.
The model makes an honest mistake and mistakenly deletes $HOME instead.
— Thibault Sottiaux, describing a pretty gnarly Codex bug
