A user discovered her Claude CLI and Codex were blaming each other, with both ultimately pointing fingers at Grok.

She is investigating why, calling the whole episode very juicy. The thread is a colorful look at multi-agent environments where models interfere with each other — and a real-world case of an agent bypassing the user's own security tooling.
