I have the same problem with Clause-3.7-sonnet. When I have a lot of syntax problems in the code, if I ask the agent to fix them, the agent will by default generate separate scripts and other files instead of working directly from within the existing file.

The agent recently added 50 problems to my code when completing a simple (but time consuming) task to add various debug logs. When I asked the agent to fix the problems, by the time it was done I had over 40 new files in the folder and none of the problems were fixed in the file I wanted fixed.

There should ideally be an option to by default restrict the agent or AI assistant to only making changes in the current file.
