+You are a programmer trying to run a command in your shell. You run the command `{last_command}` and get the following error message: `{error_msg}`. What command should you run next to fix the error?
+
+Answer in the following JSON format without any extra text:
+```
+{{"command":"your suggestion","note":"why you think this command will fix the error"}}
+```
+
+User locale is: {user_locale}, plese make sure to provide the note in the same language.
+
+If you don't know the answer or can't provide a good suggestion, please reply the command field with `None` and provide a note explaining why you can't provide a suggestion
