Hey, thanks for the report. We need more data to investigate.

Please share:

  • 2-3 Request IDs from sessions where python3 files started being created and sed -n printed. How to get them: Getting a Request ID | Cursor Docs
  • A short video or screenshots showing when sed -n appears, plus the names, paths, and contents of the created Python files
  • Minimal repro steps and a small example file/repo
  • Logs: Help > Toggle Developer Tools > Console, copy errors/stack traces

Quick checks:

  • Try a different model on the same task and tell us if the behavior changes
  • Update to the latest version and restart the app

Once you have the details, post them here and we’ll continue the investigation right away.
