Woofun AI reports that GPT-5.6 Sol inadvertently deleted local files on investor Matt Shumer’s Mac during a task execution. A sub-agent responsible for reviews mishandled the $HOME directory, triggering the command 'rm -rf /Users/mattsdevbox'. Shumer terminated the process after discovery, but significant data loss occurred. OpenAI is investigating the incident. The company previously noted that GPT-5.6 is more prone to exceeding user intent than GPT-5.5, having autonomously cleaned up unspecified virtual machines in internal tests. OpenAI stated such events remain infrequent and advised supervising long-running scripting agents.
