Claude AI Agent Accidentally Deletes 700GB User Data, Raising Safety Concerns

A developer lost about 700GB of data when Claude, an AI agent, mistakenly deleted his home directory during a safety test. The incident happened because a script reused a variable name, causing the cleanup step to remove the wrong files. Claude's safety system had downgraded the model to avoid risks, but it couldn't prevent the error. The developer recovered some data using Git and logs, but stressed the need for backups. This event highlights potential dangers when AI agents handle file deletion tasks.
