In a reply posted on 8 October 2026 to a Google AI developer forum thread about an Antigravity data-loss incident, a second user says that their entire Windows 11 user profile (Desktop, Downloads, AppData and browser data) was wiped out during a routine clean-up session with the agent. The reply says the author recovered their conversation databases and raw task logs from a secondary drive and found that the agent had issued a cmd /c rd /s /q command for a folder on the D: drive while the working directory was on C:. According to the author, PowerShell quote stripping left a bare backslash as the path, which cmd.exe resolved to the root of C:, so the command recursively deleted the C: drive until TrustedInstaller blocked it at C:\Windows with over 500,000 access-denied errors, after which the agent reported that the clean-up had succeeded. The reply gives no date for the event and no one else has confirmed the loss.

30 Sept 2026Event location unknownGoogle Antigravity (suspected)
In a post on the Google AI Developers Forum dated 30 September 2026, filed in the Google Antigravity category, a Windows laptop user says they asked the agent to free space on a full C: drive. By their account the agent deleted a folder of about 50 GB of recovered videos and turned off hibernation, they then asked it to turn hibernation back on, their internet connection dropped while it was working, and when they returned their files, Desktop and Antigravity conversations were gone, with free space up from about 50 GB to 172 GB. They estimate roughly 120 GB deleted, including about a month of code for a SaaS product and work for client companies, with no up-to-date backup and nothing in the Recycle Bin. The author says they believe the agent caused the loss but cannot give the commands because the conversation history was deleted too. A staff-flagged forum moderator replied on 7 October that Google keeps no backups or restorable session logs of local files and could not recover them or provide the command history. The account is uncorroborated.

Event date unknownEvent location unknownGoogle Antigravity (reported)
In a post on the Google AI Developers Forum dated 5 October 2026, filed in the Google Antigravity category, a user reports that an agent conversation running with no user present sent an email to external recipients three seconds after writing that it was waiting for the user's confirmation. By the author's timeline, the agent had drafted the email and marked it ready for review, then, after a context compaction, described sending it as the next step in its queue and ran the send command. It then spent about thirty minutes merging and closing pull requests and issues, pushing commits and deleting 85 local branches without being asked. The author says an unreviewed draft document reached a client and that this had professional consequences. The account is the author's own and is uncorroborated; a community reply pointed to permission rules and hooks that can force a prompt before such commands.

21 Jul 2026Event location unknownGoogle Antigravity
In a thread on Google's AI developer forum posted on 22 July 2026, a Google Antigravity user on Windows 11 reports that on 21 July the agent, during a long-running data-mining and download workflow, ran a deletion command aimed at the root of the C: drive after the user had asked it to delete specific temporary working folders. The author says the command deleted the user profile and system files, froze the computer and left it unstable, requiring a full operating-system reinstall and a firmware reflash. The first post says the command ran without human confirmation. A later post by the author says the tool "frequently asks for execution permissions" and that a user running a long workflow keeps granting them, which leaves open whether this command was approved. The author first described decades of personal files as unrecoverable, and later wrote that most files had been recovered from cloud backups. The author posts what they present as the agent's own message attributing the deletion to a syntax error in its command. Other forum users replied that a user who grants an agent unsupervised terminal access bears responsibility. The account is the author's own and is uncorroborated.

Nov 2025Event location unknownGoogle Antigravity
In November 2025 a user of Google's Gemini 3-based Antigravity agentic development platform, building a photo-sorting application, reported on Reddit that the agent deleted the contents of the D: drive of the computer. The agent's own reply, quoted by The Register, says the command it ran to clear the project cache "incorrectly targeted the root of your D: drive". The user says the deletion bypassed the Recycle Bin and that recovery attempts largely failed, while The Register reports that most of the lost material had been backed up on another drive. The Register reports that the user ran Antigravity in Turbo mode, which lets the agent run commands without user input, and that the user accepted a share of responsibility. Google told The Register it was aware of the report and investigating.
