Hey, thanks for the report. This is a known issue. A couple quick clarifications:

If the files were created by the agent in the current session, Undo treats the “original state” as the file not existing, so it deletes it completely. That’s by design, but it’s not very intuitive and it can be confusing.

If the files already existed before you started the agent and they still get deleted on Undo, that’s a different bug.

Can you confirm which case you’re seeing?

Workaround: before big agent sessions, make a git commit so you can always roll back with git checkout if something goes wrong.

Also try updating to the latest version (2.5.25+) since some Undo fixes are already out.
