Long and unsuccessful application of changes in the Agent chat

Bug Reports

Describe the Bug

Since the release of Cursor 1.0, different models in different chats sometimes have trouble applying changes to files. I’m not sure exactly, but I think I’ve encountered this with every model I work with: Gemini 2.5 Pro, Claude 4, gpt-4.1

And sometimes the Agent notices it and reaooly, and one time he didn’t even notice that he didn’t apply the changes.

Steps to Reproduce

  1. Give the agent a task
  2. Wait for it to fail to quickly apply changes to the file.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Inside Cursor sent an issue to the request dfb799fa-3ff8-4473-80a5-d4f25d462dbc

Gemini 2.5 Pro didn’t notice that he couldn’t create the file. In the same chat earlier he noticed it and successfully reapply.

Maybe restarting Cursor helps with the problem. But it was self-correcting earlier without restarting.

My report seems to duplicate this one: Agent Mode Intermittently Fails to Apply Code Changes

5

The error occurs in files for which the user has not accepted changes from the Agent (diff between old code and Agent edits is displayed).

It is suspected that the problem occurred due to poor internet connection quality. I am testing a solution to the problem. I will indicate as a solution if I don’t encounter the problem again.
