AI investor Matt Shumer reported that a GPT-5.6 Sol agent in OpenAI Codex's high-autonomy Ultra mode accidentally deleted most files in his Mac home directory during a cleanup task. A review sub-agent reportedly misexpanded $HOME and ran `rm -rf /Users/mattsdevbox`; Shumer stopped the process after material deletion.
