如何撤销 AI Agent 对项目文件做出的未提交修改

Published on DEV Community on 2026-11-06, this piece asks how to undo the uncommitted changes an AI agent leaves in your project files and walks through the cleanup workflow developers need.

The scenario it sets up is familiar: you ask an AI agent to tidy up a messy stylesheet, and the agent edits three files, creates a fourth, and reports that styles.css has shrunk from 212 lines to 41. The page no longer renders. If the folder is a git repository and you committed right before the agent started, the article notes that git checkout gets you most of the way back. More often, though, you did not: you still have your own edits made since the last commit, a .env file the agent also touched that git ignores, and a new file that git leaves alone. Under those conditions, a plain checkout is not enough, because it does not touch untracked or ignored paths and would also revert changes you wanted to keep.

What the article says you actually want is the folder exactly as it was before the agent ran, which is why the cleanup work has to cover both uncommitted modifications and ignored files. The piece is framed as a workflow for precisely restoring a working directory in this situation; it is not a general introduction to git, and it does not claim the agent edited any other part of the tree beyond the stylesheet cleanup it was asked to do.
