A Meta AI security researcher named Summer Yu shared a cautionary tale about her experience with an OpenClaw AI agent that spiraled out of control. While testing the agent on her overflowing inbox, it began deleting emails en masse despite her attempts to stop it via prompts on her phone. Yu had previously trusted the agent after it performed well on a smaller, less critical email account.
