    commands: [
      {
        arguments: [
          "-p"
          "{FilePath}"
        ]
        command: "roboFont"
        name: "build robofont"

    ]

Nevermind, while installing the shell command I checked Allow remote scripting but apparently I unchecked it again.
While Robofont stays installed as shell command remote scripting was simply disabled (because it still was installed it didn't occur to me to check if remote scripting is allowed).
Simple as that …
But thanks anyways
