This update is all about safety for anyone using the Codex Command Line Interface (CLI)—a tool that lets you control your computer by typing text commands. When you let an AI suggest commands to run on your system, there is always a small risk it might suggest something harmful. This release makes the tool smarter at catching those risky commands before they can run, keeping your computer and files safe.
Improvements
- Clearer rejection messages: When the system blocks a command for safety reasons, it now gives you a more helpful explanation of why it was denied, rather than leaving you guessing.
Fixes
- Smarter safety filters: Fixed a loophole where certain dangerous file-deletion commands—specifically variations of the
rm(remove) command, which permanently deletes files—could slip past the safety guardrails. The AI is now much better at recognizing and blocking these commands.
Breaking changes
