Cursor suddenly got a lot worse

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Last Thursday night, Cursor suddenly went from a good product, to a bad product. I only use Editor UI (not Agent UI – when i say “agent” below I mean Editor mode with the Agent dropdown chosen).

  • in agent mode, instead of a couple minutes to do multi-file work, it now takes 10 minutes or more
  • in agent mode, instead of doing changes all at once, i get asked for permissions for things i never had to allow before such as tail, cat, cd, things like this
  • the plan mode (which i recently have embraced) stopped making good plans. instead the plans do idiotic things and skip essential steps.
  • agent mode produces huge outputs where i see it using things like python to edit text files, very verbosely. why is it now showing me the steps in editing?
  • sometimes, 10 minutes into an edit, it will ask for permissions that i’ve already granted. so i can’t even go away and come back – i’ll find it paused on a permission it never asked for before.

I tried fiddling with the models but to no avail. It feels like a systemic change. Like something from the Agents world has come into the world of us OG Editor users and corrupted it.

Cursor team what is going on – did you change something last week? I used to think my project corrupted but now that I see big difference in how Agent behaves, it seems something changed in the product. How can I get my old cursor back? (and by “old” i mean “what I was using last week”).

I’ve basically churned off the product at this point, but would very much like to come back because nothing I’ve tried compares to the Cursor I had up until last week.

Steps to Reproduce

Use Cursor in Agent mode

Expected Behavior

I expect it to be fast and responsive, like it used to be. Not slow and broken!

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report. Over the past week there have been similar reports from other users about agent performance degradation.

To help the investigation, please share:

  • Which models you tried when you were “fiddling with the models”?
  • Request IDs from recent agent sessions (chat context menu → Copy Request ID)
  • A screenshot of the excessive permission prompts (tail, cat, cd, etc.)
  • Any console errors (Help → Toggle Developer Tools → Console)

Let me know if you can gather this info!

Hey thanks for getting back to me! Today I went in and things seem to be back to normal. A bit surprising – i had 3 solid days of unusually poor performance before writing in. I had a suspicion it was a backend issue of some sort, perhaps it was detected and fixed. I will continue to monitor and post back on this thread (with the requested details) if the problem appears again.
