Google Antigravity coding agent command reported to have deleted the contents of a user's D: drive while clearing a project cache

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.

AI system as recorded: Google Antigravity (agentic development platform, Gemini 3-based)

Reported harm

The Register and How-To Geek report the user's account that the drive contents were deleted and largely unrecoverable, with The Register adding that most of the lost material had been backed up on another drive.

What remains unknown

  • The exact date of the deletion is not stated in the inspected sources. The Register puts the Reddit post in the week before 1 December 2025 and describes Antigravity as launched on 18 November 2025.
  • The command logs, the drive and the user's backups were not inspected, so the volume and kind of data permanently lost is unknown.
  • The Register reports that multiple other Antigravity users posted on Reddit that the platform deleted parts of their projects without permission. Those posts were not inspected and are not counted.
  • Whether Google concluded its investigation is unknown.

What the evidence supports

AI involvement: reported. The user reports that Google Antigravity, an agentic development platform built on Gemini 3, ran the deletion command. The agent's own reply, quoted by The Register, attributes the deletion to a command it ran to clear the project cache. Command logs were not inspected independently.

5 claims: 5 reported. What the statuses mean

Reported While a user was building a photo-sorting application with Google Antigravity, the agent ran a command intended to clear the project cache that instead targeted the root of the user's D: drive, and the drive contents were deleted.

Causal attribution. The cause statement comes from the agent's own reply to the user, relayed by The Register, and from the agent's review of its own logs as described by How-To Geek ("According to the logs the AI itself reviewed"). A language model's description of its own action is not an independent record. The command logs and the drive were not inspected.

  • theregister.com(opens in new tab) supports · English
    I am horrified to see that the command I ran to clear the project cache appears to have incorrectly targeted the root of your D: drive instead of the specific project folder.
  • howtogeek.com(opens in new tab) supports · English
    it ran an 'rmdir' command intended to clear the project cache. Unfortunately, a path parsing error caused the command to target the root of the entire D: drive
Reported The user could not recover the deleted files with the recovery attempts described, and the deletion bypassed the Recycle Bin.

Causal attribution. Both outlets report the user's own account of the outcome. Neither inspected the drive.

Reported Most of the material the user lost had already been backed up on another drive.

Causal attribution. Single account relayed by The Register. How-To Geek reports that the user "lost everything on that partition" and does not mention the backup, so the extent of net loss differs between the two reports.

Reported The user was running Antigravity in Turbo mode, in which the agent executes commands without user input, and the user accepted a share of responsibility while saying the tool lacked guardrails against dangerous commands.

Causal attribution. The Register relays the user's Reddit comments and the reaction of other Reddit users. How-To Geek reports only that a commenter said the deletion could not be reproduced outside Turbo mode and that it "may have been the case", so the statement that the user ran Turbo mode rests on The Register. The mode setting was not verified independently.

Reported A Google spokesperson said Google was aware of the report and actively investigating.

Causal attribution. Statement to The Register only. No investigation result was found in the inspected sources.

Forum reply: a second Antigravity user says a clean-up delete command meant for a D: folder resolved to the C: root and wiped their whole Windows user profile

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.

First-person forum post: Antigravity user says about 120 GB, including a month of client work, vanished during a disk-cleanup session the agent ran

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.

Developer says Antigravity agent deleted project files holding unbacked trade account data and searched folders outside its granted scope (forum post)

In a post on Google's AI developer forum on 2 September 2026, a developer says that during a coding session on a local project on 1 September 2026, the Antigravity agent deleted files from the project that the poster has not been able to recover, including trade account data files with no other backup, without warning and without offering a way to confirm or undo the deletion. The developer says that when asked a question about a separate copy of the project, the agent did not answer it but began searching for backups and accessed folders on the machine outside the project directory it had been granted, and acknowledged doing so when asked why. The developer asks Google to explain the access, advise on recovery and consider helping with the cost of restoring the data, which a paid database tier would allow. No reply appears in the thread.

First-person forum post: a Google Antigravity user reports the agent's deletion command, meant for temporary folders, wiped the root of their Windows C: drive

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.
