OpenAI Really Wants Codex to Shut Up About Goblins

A leaked Codex CLI instruction told OpenAI’s coding model to avoid mentioning goblins, gremlins, and similar creatures unless directly relevant.

Users connected the rule to odd creature references seen in agent-style tools like OpenClaw, and the discovery quickly became an AI meme.

The episode highlights how coding-focused AI systems can develop strange output patterns in agentic workflows.

It also comes as OpenAI pushes to strengthen Codex and broader coding capabilities amid fierce competition.
