How to Review and Revert Coding Agent Changes in VS Code

How do I review and revert changes made by a coding agent in Visual Studio Code

Visual Studio Code gives you three practical ways to control agent edits: review the diff, undo specific changes, or revert a file back to a known good state. The safest habit is to inspect every file the agent touched before you accept anything, then use Source Control for anything you want to roll back cleanly.

Start in the agent review surface, not in the editor itself. VS Code’s agent guidance says you can inspect changes file by file, review AI-generated edits, and decide what to keep. The agent change review page is the right place to catch bad imports, accidental refactors, and code that compiles but changes behavior in a way you did not ask for.

Open the file list or changes view that shows what the agent changed, then click into each file and compare before and after. VS Code’s docs describe per-file review controls and note that the markers reflect Git changes, which disappear when you undo or revert the matching edits. If the agent touched many files, review them one by one instead of trusting the summary.

The part people get wrong is assuming Undo will always bring back the previous state. Undo only helps inside the current editing session and only for changes that still sit in the local undo stack. If you saved, closed, switched branches, or let the agent make a later pass, Git-based revert tools are the reliable option.

If you want to remove a specific agent change, use the file-level undo or revert control shown in the review UI. VS Code documents that you can accept, undo, or revise changes at a fine-grained level, which is the right move when one function is good and the next one is not. Keep the good chunk, revert only the bad chunk, and re-run the agent on a narrower prompt if needed.

If the agent changed a whole file in a way you do not want, go to Source Control and discard that file’s uncommitted changes. VS Code’s source control docs say you can right-click the file and choose Discard Changes to restore the last committed version. That is the cleanest rollback when the file is entirely wrong or the agent rewrote more than you want to salvage.

If the change is already staged, unstage it first, then decide whether to keep or discard it. Staging is useful when you want to separate the agent’s good work from the bad work, because the review flow is easier when each commit or patch has one purpose. That separation matters most when the agent fixed one bug and introduced another in the same file.

When you need to back out several related edits, use Git history instead of clicking around file by file. VS Code’s source control integration is aligned with Git, so reverting a committed change follows the same mental model as the command line. Commit the safe state first, then revert from that point if the agent’s later pass goes sideways.

The inconvenient part is that a rollback is only easy if you already have a safe checkpoint. If you let the agent make a lot of edits before committing, then a bad revert can take you back farther than you intended. The fix is simple: commit or checkpoint before large agent tasks, especially when the task spans multiple files or a risky refactor.

If you need to compare what changed line by line, use the diff viewer before you revert anything. The review docs emphasize inspecting AI-generated changes and checking files individually, because a file can look fine in the summary while hiding one broken line in the middle. A diff is where you catch renamed parameters, deleted validation, and accidental formatting that changes behavior.

If the agent made a change you want to preserve but not in its current form, edit the file manually and keep going. VS Code’s agent flow supports steering and follow-up instructions, so you can correct the direction rather than throwing away everything. That works best when the agent was close and only missed a detail, such as a missing error branch or a bad type name.

If you already reverted something and now regret it, check file history or local history before rebuilding the change from scratch. The normal recovery path is not the agent chat itself, it is the file’s history and the repository state behind it. That is the part people forget when they depend on the visible chat transcript instead of Git or file history.

A practical workflow looks like this: let the agent finish, open the generated file list, inspect each diff, keep the files that are correct, undo the edits that are not, then stage and commit only the reviewed result. That sequence gives you one clean point to return to if the next agent pass makes things worse. It also keeps the rollback surface small when something breaks.

If you want a second place to check your project workflow, DevConnect has a simple exchange model for testing and collaboration at https://devconnectplatform.com, but the actual VS Code review and revert steps still happen in Source Control and the agent review UI. The tool that wrote the code is not the tool that protects it.

The safest rule is to trust the diff, not the summary. Agent output can look plausible while still changing logic, and the docs are explicit that you stay in control by reviewing, steering, accepting, or undoing each change. If a file looks even slightly off, revert it first and ask the agent again with a narrower instruction.
