Worktree apply does not work (and other bugs)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

The “Apply” button in the multiple models/worktree mode does not work. I was able to click the apply button both from the chat window and the review window but neither worked. Accepting the changes didn’t do anything either.

Another issue I regularly see in this mode is that even before the agent has made any changes it opens up unsaved files in the worktrees and they stay unsaved even after the agent is done. Seems like closing them without saving does nothing.

And since the apply button is broken this whole workflow is pretty much broken unless I’m using plan mode.

Steps to Reproduce

This will work for both issues I’ve described above:

  1. Enable “Use Multiple Models”
  2. Ask for a change in Agent mode
  3. After agent is done, click on “Apply” in the review mode or in the chat window

Expected Behavior

  1. I should not be seeing unsaved files at all.
  2. Clicking on Apply should move those changes to the base branch.

Operating System

Windows 10/11

Hey, thanks for the report. This is a known issue with worktree / multiple models mode, and we’re seeing a few related bugs in this area.

Two main things you mentioned:

  1. The Apply button doesn’t work. This is a known issue and the team is working on a fix.
  2. Unsaved files show up in worktrees. This is also on our radar.
