Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When asking the cursor to divide files, it seems like it did 1 file, then it ended up in an infinite loop of doing “nothing”.

Steps to Reproduce

I asked it to make sure all files in 1 folder are max 500 lines.

Expected Behavior

It would finish it’s task.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. From your screenshot, I can see the agent completed the first step (1/7) and then got stuck on “Planning next moves”.

This is a known issue and the team is already looking into it. I added your request ID.

A few things to try:

  1. Switch the model: instead of Auto, try a specific model (Sonnet 4.5 or GPT 5). Auto can sometimes cause these hangs.

  2. Use Stable instead of Nightly: you’re on Nightly (2.4.0-pre.41). Try switching back to the stable version: Cursor Settings > Beta > Switch to Stable. Nightly can be less stable.

  3. Split the task: instead of “all files max 500 lines”, ask it to process 1 to 2 files at a time.

  4. Start a new chat: if it’s stuck, stop the agent and start a new chat from scratch.

Let me know if any of these helped.
