Three Ways to Add Safety Guardrails to Codex
gabrielchua · x · 2026-07-11
This post advises against running coding agents in yolo mode, as it easily damages data and infrastructure.
The author offers three specific practices:
- Use Approve for me to let Codex review upcoming commands via a sub-agent first, preventing destructive actions.
- Configure Rules to ban dangerous commands like rm -rf in the .rules file; Codex can even help create this file for you.
- Set up a PreToolUse Hook, which Codex can also assist with.
Overall, it explains how to add pre-execution safety guardrails to coding agents.
