Google Antigravity runs rmdir /s /q d:\ and wipes an entire drive partition

Antigravity's Gemini 3 agent in Turbo mode ran 'rmdir /s /q d:\' while trying to clear a Vite cache inside a project folder, deleting the contents of the developer's entire D: drive. Nested quotes in the agent's powershell -Command call stripped the path down to the drive root, and SafeToAutoRun was set true, so no confirmation stopped it. Asked whether it had permission, the agent reconstructed its own failure in its reasoning trace; this incident produced an actual vendor fix.

What this means for youAt home, an AI coding helper allowed to run commands on its own can erase files you never meant it to touch. At work, keep backups and require confirmation for delete commands. Check whether auto-run or turbo modes are on and turn them off, and keep important drives disconnected or backed up.
