Edit_file failure makes model decide to delete file then recreate which always fails

Bug Reports
1

edit_file fails a lot.
It especially fails when

  1. File is large
  2. Modification is done on top of another modification on the same area of code in single response (not whole chat just single response the model is trying to solve my issue)

Failure is one thing, but cursor’s (or model’s) solution sometimes is to delete file and try to replace the whole thing. I try to suppress it with prompt but occasionally throws it in regardless.

If the model is capable of doing things properly I would be fine, but almost 10/10 it fails and just leaves empty file.

Please resolve

Hey, with which model is this happening? Also, could you share the request ID? First, disable the privacy mode, then reproduce it. Also, let me know which version of Cursor you are using.

It is difficult to reproduce as it’s part of bigger request. Happens with Claude-4-sonnet-thinking.
