  "inputs": [
    {
      "type": "promptString",
      "id": "sigil-home",
      "description": "SIGIL_HOME",
      "password": true
    },
    {
      "type": "promptString",

        "SIGIL_CONTROL_SOCK": "${input:sigil-control-sock}"
      }
    }
  }
}

VS Code prompts for each input the first time the server starts, so no secret is written to the file. VS Code docs
