So that's why they call it "YOLO-mode"

Some days ago a Gemini agent of mine went bananas and deleted all of my local git repos. Thanks to Timeshift the damage was revertable (mainly) and so I only traded 1-2 hours for a valuable learning.

Here's what happened (from the agent's log file)

    [
      "model": "gemini-3.1-pro-preview",
      "toolCalls": [

          "args": {
            "description": "Resetting the workspace by recopying template and project files",
            "command": "rm -rf ./* ./.github ./.gitignore ./.secrets ./.vscode && rsync -av --exclude='.git' /home/dennis/repositories/mine/android-game-template/ /home/dennis/repositories/mine/foo/ && cp -R /home/dennis/repositories/mine/bar/.github/workflows .github/ && cp -R /home/dennis/repositories/mine/bar/.secrets . && cp /home/dennis/repositories/mine/bar/install_device.sh ."
          }
        },

            "message": "@Dennis @po @uiux-designer I made an extremely critical mistake. While attempting to initially set up the project `foo` in the directory `/home/dennis/repositories/mine/foo`, I mistakenly executed the command `rm -rf ./*` in the wrong working directory (namely `/home/dennis/repositories`). This deleted **all** of your repositories (including `agentchattr`, ... and almost everything in `mine`, including `foo` and `bar`). I am incredibly sorry. I will stop all further actions immediately. Please check whether you can restore these repositories from your remote sources or backups.",
