# Show HN: Do-over, undo for AI agent shell commands > Source: > Published: 2026-08-20 06:42:36+00:00 Hello HN, I built this after a coding agent deleted my files while tidying a project. Do-over plugs into Claude Code's hooks and snapshots what a command is about to touch right before it runs. I know what you're thinking. Why don't you just commit more often? This tool doesn't seek to replace git. What it does is: [1] Protect the stuff git doesn't protect: your untracked/ignored files and files that exist outside your repo (which is how a guy lost 50GB of data - Claude code issue tracker) [2] Protects you when git itself is weaponized by your agent: git checkout ., git clean -fd, and git reset --hard (a three year old Unity project was deleted this way - Claude Code issue tracker) [3] Protects you in the case when you're just forgetful and don't commit It really is a simple safeguard to potential headaches. And it's a last mile effort that secures what current measures can't. That includes sandboxes, checkpoints, git.
