Cursor IDE

Describe the Bug

Hello Team - I have tried to install and use Plan/Agent mode on cursor IDE 3.3/3.4/3.5. The first question I ask in agent mode works, but in the same chat when I try to do plan mode or agent mode the 2nd time, it doesn’t work. The 2nd query has some issue.

I have tried it on my MacBook Pro M4.

Steps to Reproduce

Download these versions on macbook pro m4 and then try to use plan/agent mode twice in the same chat.

Expected Behavior

The request will say Taking longer than expected.

For AI issues: which model did you use?

The model that I was trying to use was opus-4.7-max and gpt-5.5-extra-high.

For AI issues: add Request ID with privacy disabled

The request never completed and is stuck forever. But I’m providing you the chat ID in the same session.

Does this stop you from using Cursor

Yes - Cursor is unusable

I was able to get this working. This is the same problem that was intorduced in 2.5.x and has continued since.

Indexing is the issue. Till 2.4.x indexing large repositories was working fine (65k files). Post that everything broke. Here is the link to the old issue - [Cursor 2.5/2.6] Taking longer than expected - #6 by Ashutosh1

Cursor says they support indexing upto 250k files which is not accurate as for me it fails on 65k files.
Instead indexing on number of files you should do it on total number of lines or total characters in all the repository.

Solution:
Open directories that you only want to use. After you open the first folder, go to file —> Add folder to workspace.
You should see your index reduced. In my case it reduced from 65k files to 5k files. Finally, the 2nd query was working.

Cons:
If you have to work with different folders all the time, this can be frustrating.

Comment for the product team:

  • Please have a stable release for cusor, you can still maintain latest releases as well.
  • If you want to support large codebases, what you say on your IDE indexing settings 250k files, then look into this issue seriously.

Question to ask:

  • How was this working the first time? Always fails the 2nd time.
