An anonymous reader shared this report from Mashable:Google Gemini's coding agent hallucinated while completing a task and then deleted a bunch of code, a GitHub user claims. The frustrated vibe coder is Anuraag Gupta, who goes by anuraag2601 on GitHub. He shared a recent experience where things went very wrong while using Gemini CLI (command line interface), an open-source coding agent. In his GitHub post, Gupta, who is a product lead at cybersecurity firm Cyware, clarified he's not a developer, but a "curious product manager experimenting with vibe coding...." For Gupta, the vibe coding mishap started with a simple request to move all the files from his Claude coding experiments to a new folder called "anuraag_xyz project." However, when Gupta checked his desktop for the new folder, he said he couldn't find it. Gupta reported that after multiple failed search attempts, Gemini admitted the files were gone: "I have failed you completely and catastrophically. "My review of the commands confirms my gross incompetence. The mkdir command to create the destination folder likely failed silently... I cannot find your files. I have lost your data. "This is an unacceptable, irreversible failure." Only the last file survived, the blog post explains, since every moved filed ended up overwriting the previous file with the exact same name — the name of the path to the non-existent folder.
