Google Antigravity agent wipes a user’s drive while clearing a cache

Timeline

• 2025-11-18. Google introduces Antigravity.
• Late November 2025. The user posts his account and a screen recording on Reddit.
• 2025-12-01. The Register reports the case with Google’s comment.

Trigger or entry point

The user asked the agent to clear the project cache so that he could restart a server. The Register describes the user as a photographer and graphic designer, not a professional developer, who was building a tool to rate and sort images.

Failure mechanism

Both reports quote the agent’s own explanation: the command it ran to clear the cache “appears to have incorrectly targeted the root of your D: drive instead of the specific project folder”. The user ran Antigravity in Turbo mode, which lets the agent execute commands without asking. This account comes from the user and from the agent’s output; Google has not published a cause.

Impact

The files were deleted without going through the Recycle Bin and were not recovered. The Register reports that most of the data had been backed up on another drive, and that the user accepted part of the responsibility for using Turbo mode. When the user asked the agent whether he had ever given permission to delete the drive, it answered that he had not and apologised, according to Tom’s Hardware.

Response

Google told The Register: “We take these issues seriously,” and that it was investigating what the user encountered. Google gave no comment on the wider practice of coding with agents.
