Why is my Ouput window opening?

Here are my commands:

    {
      "match": ".*\\.ex*",
      "command": "mix format ${file}",
      "runIn": "backend",
      "runningStatusMessage": "formatting ${fileBasename}",
      "finishStatusMessage": "${fileBasename} formatted"
    },
    {
      "match": ".*\\.ex*",
      "command": "mix credo ${file}",
      "runIn": "backend",
      "runningStatusMessage": "linting ${fileBasename}",
      "finishStatusMessage": "${fileBasename} linted"
    }

Every time mix credo is ran, my Output window pops open; it's really annoying. How can I debug this? I don't see a setting for vscode-run-on-save that disables Output from opening. It may be something with credo as well, still looking into it. Thoughts?

And of course I solve this a minute after opening an issue 😆 credo exits with a 0 status by default, which is why the Output flies open. Changing the command to mix credo ${file} --mute-exit-status solves the issue.
