Codex randomly stops working because some silly cybersecurity detector. Insane amount of false positives. Last time it happened, I was just letting it write me a small tool to translate the text in my clipboard. What cybersecurity? Code wasn't even published, or remotely like anything hacking related. I'm always letting AI write some boring CRUD tools that I don't want to code myself.
It's probably their system prompt. Unlike Claude Code, they don't ban you for using different harness with their subscription (for now). If you use pi, their "safety" is off. Works great for me.
It's bordering on being useless.
