Tab complete suddenly very agressive

Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I use the tab complete option alot, but lately it’s been very agressive in deleting code that is perfectly valid.
I will tab complete to add a block of code, then it immediately wants to delete the code.
I will scroll down the file and it will just randomly highlight perfectly valid code or even critical code and suggest to delete it. No justification or anything.

I want to keep the tab option, but at this rate I;m turning it off more and more to keep it from destroying my code.

Is there some way to tune it so it is less agressive? Or options to prevent random deletions of code outside of an add?

Steps to Reproduce

Hit tab complete to complete a chunk of code and more likely than not, the code that was just added will be suggested to be deleted.

Expected Behavior

Don’t randomly suggest to delete code.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. Lately, we’ve been seeing similar feedback about overly aggressive Tab autocompletion.

Unfortunately, there aren’t any settings right now to finely tune the “aggressiveness” of Tab suggestions. Current options:

  • Set a shortcut to toggle Tab, so you can temporarily disable it or turn it off for specific file types
  • Temporarily turn it off when you’re working in critical sections

To help the investigation, please share:

  • Which file types this happens in most often
  • Any noticeable pattern (for example, more often after certain actions)

This will help the team determine whether there’s a regression in recent versions.

I’m coding in Python and C (.py, .c)

There are 2 main problems that if they were fixed would make tab usable again:

  1. If I hit escape to dismiss the Tab suggestion, don’t popup another suggestion. I dismissed it so I can get the TAB key control back. Hitting ESC should leave tab completion OFF untill the cursor moves or I hit enter.
    Often times I hit ESC multiple times before it clears. Very often in keeps suggesting different completions until the final one is to delete everything (WTF!!!)

  2. The index for TC needs to update itself much more often. Many times i delete or change some code or viarbale, but TC keep suggesting to either

  • put it back in (even though I explicitly deleted the code)
  • Use it in the following lines even thought the variable no longer exists

All of this makes the TC feature so frustrating I leave it off most of the time.

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Using cursor 2.0 on a python repository.

About every 5-10 inline suggestions I accept (), the next suggestion is to delete an entire block of healthy code in the lines that follow. This makes fast acceptance of suggestions extremely dangerous and the IDE as a whole barely trustworthy to use.

It has been happening consistently for the past week.

I checked, this is not dead code due to indentation issues or otherwise.

Steps to Reproduce

Just using cursor triggers it constantly, even when editing a comment, it decides the next action should be deleteting 20 lines of code.
