How do I configure Cursor to automatically detect and fix Python errors when running a script from the terminal?

There isn’t a single Cursor setting that will monitor anything you type into the integrated terminal and automatically edit your code until the script stops crashing.

You can do this:

1. make Cursor detect terminal errors as editor diagnostics (clickable file/line in Problems)

2. drive a loop where the Agent (or the Cursor CLI agent) runs the command, reads the traceback, fixes, reruns

3. Turn terminal tracebacks into Problems (so Cursor can “detect” them)

Don’t run python main.py manually. Run it as a VS Code task with the Python problem matcher.

Create .vscode/tasks.json:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Run main.py",
      "type": "shell",
      "command": "${command:python.interpreterPath}",
      "args": ["${workspaceFolder}/main.py"],
      "problemMatcher": "$python",
      "presentation": {
        "reveal": "always",
        "revealProblems": "onProblem"
      }
    }
  ]
}

Now run it via Command Palette -> “Tasks: Run Task” -> “Run main.py”.
