How is there not a /rewind or /revert feature?

[notnotjake]

Rewind or revert feature is very much needed. OpenCode and Claude Code have great support for undoing. Unless you want to commit on every change, not having this is insane and makes codex almost unusable.

We previously exposed an experimental /undo command. It didn't get much use, and its design caused problems for many users, so we removed it. If you'd like to see something like this, please upvote this issue. We generally prioritize our feature development based on signal from users (as measured by upvotes).

I think that most Codex users don't see the need for /undo because they either use git to commit and revert changes or they rely on Codex to undo its own work when needed (e.g. "Undo that last change and redo using option 2").

This is a very naive point of view, doubly so now that you removed the ability to prohibit codex from editing files without permission / explicit approval.

Case in point, I asked Codex for a review of a document that was uncommitted. I wanted it to be solid before committing. Codex decides my design doc (that I spent an hour on) is "out of sync" with the current repo, so it deletes it and recreates a much shorter one. Nothing I could do to keep it from doing that (didn't ask for permission to edit the file because you removed that /permissions setting). Now I want to undo, but can't because you removed /undo. And guess what, that original file was 1000+ lines long. I asked Codex to undo its changes and it produced a doc that was ~450 lines long.

You can't remove safeguards and the ability to revert and have a model that can't reliably undo its own changes. This makes codex unusable for anyone doing serious work. Meanwhile Claude Code has safeguards and revert. How/why would you assume you shouldn't have a certain minimum of parity with your biggest competitor? Especially when it comes to safety and developer ergonomics?

Lucky for me I have automatic backups using Time Machine, but this is honestly unacceptable.

You decided to revert alone ? why button still in extension (and not works) ?

this impress codex as buggy raw product. no consistency.

Can we distinguish between an "undo" feature and a "restore conversation to this point" feature?

My understanding is that a true "undo" might be more complex to implement reliably, since it would need to reverse prior actions and state changes. In contrast, "restore conversation to this point" seems more like a context management operation, where the conversation state is reverted to an earlier message and everything after that point is ignored.

I can implement the restore logic on my side, but I’m unsure about the correct approach to trimming the context. Specifically, how should I prevent messages after the restore point from being included in the next request? Should those messages simply be removed from the message history before sending the next prompt?

I personally didn't liked undo. Did not used it much but it wasn't feeling right. I don't know why.

I need exact /rewind feature as claude code cli. It asks me to rewind either conversation or code&conversation which is pretty useful when you are not ready to commit yet but want to try something.

With agentic coding I experiment with my codebase a lot and not being able to go back is pretty much blocks this process for me.

Also undo button exists on vscode extension right now but not working at all.

I hope we can get a proper rewind/revert/restore checkpoint feature which would make codex 2x useful for me.
