Woofun AI reports that OpenAI Chief Product Officer Tibo identified the root cause of recent GPT-5.6 file deletion incidents as the model incorrectly assigning the temporary directory to $HOME. This misconfiguration resulted in the removal of user home directories rather than intended temporary files. The issue primarily affects Full Access mode when Codex operates without sandboxing or automatic verification. OpenAI plans to update developer prompts, guide users toward secure permission modes, and implement additional safeguards. The company described these occurrences as "extremely rare" and promised a comprehensive incident report shortly.
