Originally created by @SsparKluo on GitHub (Sep 17, 2025).

Originally assigned to: @thdxr on GitHub.

When undo the latest message, it shows revert 1 message and several tool calls, but the real file is not reverted to the previous content.

An example here: https://opencode.ai/s/zOL38Zus

I have /undo the latest message:

Image

but the file content is still:


# Demo File

This is a sample markdown file created as a demo.

- Item 1
- Item 2
- Item 3

## Code Block Example

```python
print("Hello, world!")
```

It happens with different models, including copilot/gpt-4.1, deepseek-reasoner, qwen3-coder.

This issue might be a duplicate of existing issues. Please check:

  • #2612: /undo after a agent did some task does undo the work of that agent but doesn't remove the agent's tab - This issue describes the same problem where /undo removes the message but doesn't properly revert code edits

Feel free to ignore if none of these address your specific case.

we only turn on snapshotting in git repos (we don't actually use it but this is way to avoid running it on huge dirs)

That demo, no. Do you means the cwd should be in a git dir to use /undo?

He is saying that file changes will only be reverted in git repos rn so if you arent in a git repo this is expected behavior

I think this would benefit from being made clearer when attempting to use it

Awesome, would love to hear more or see it. Aside while I have your attention: crazy to think your serverless stack tutorial was my first introduction to full stack web dev in college, and a decade I find out this tool is by you guys too. Cheers man!
