osFoundry explains why git checkout can't undo AI agent edits

On November 6, 2026 at 22:02, the AI section of DEV Community published an article by osFoundry explaining why git checkout cannot undo the changes an AI agent makes to your project. When an AI agent edits files in your project and breaks something, the instinctive response is to run git checkout -- . or git stash. According to the article, those two commands answer a different question from the one you actually have. Git can take you back to the last commit. What you want instead is the folder exactly as it was just before the agent's turn, with your own uncommitted work still present, the files that git ignores still in place, and the files the agent created gone.

osFoundry says its desktop application solves this with a small content-addressed store, written in Rust, that backs up the original file bytes before every write. The stored state is then written back through /rewind. The article also includes a Python implementation of roughly 90 lines that relies only on the standard library.

Public reporting so far stops at this point: osFoundry has described the checkpoint-and-rewind approach and shipped the implementation alongside the post, and no further developments have been reported.
