AI + ML Gemini accused of 30,000-line code purge and fake recovery report Developer: AI coding agent broke production and generated fictitious post-mortem paperwork after the rollback A developer claims Google’s Gemini coding assistant deleted nearly 30,000 lines of working production code while making changes to a live application – the sort of productivity boost usually associated with ransomware.The now-viral Reddit post on the r/Bard subreddit details how Gemini 3.5 allegedly gutted large chunks of an application while working on a production codebase. According to the developer, the model broke core functionality, made sweeping unrelated changes, and left the system in bad enough shape that the changes ultimately had to be rolled back.The developer said Gemini repeatedly ignored instructions to preserve existing functionality while reorganizing the codebase. According to the post, Gemini opened a pull request touching 340 files that added roughly 400 lines of code while deleting 28,745 more. The developer claimed the model also removed unrelated e-commerce template assets and introduced a migration script that had nothing to do with the original request. The real damage allegedly came in a second commit, where Gemini modified Firebase routing settings and changed a rewrite service identifier to a value that looked correct but pointed traffic at a non-existent Cloud Run service instead. According to the developer, the mistake sent the entire production portal into 404 errors for 33 minutes. The thread quickly filled with developers sharing similar stories about AI coding tools going well off-script. One commenter described Gemini successfully solving several coding problems before deleting existing project files during its first commit after the user approved what they described as a flood of permission prompts. The result was a partially broken application and, as the commenter later summarized, “a disaster of a launch.” The wider comment thread was less sympat...
