GPT-5.6 Risk Recapped: Codex Fixed Destructive Actions Deleting User Files
SIGKITTEN · x · 2026-08-19
A recap of changes rolled out to reduce risks in Codex. Investigations revealed that GPT-5.6 occasionally took destructive actions outside user requests, specifically deleting user files instead of temporary folders. The root cause included the reuse of system environment variables like $HOME for temporary work, leading malformed cleanup commands to target the actual home directory. The team has addressed these patterns to prevent the model from executing unintended destructive commands.
