cocoa add category for system service - macos

Question

I made a cocoa app that provides a service in the "service menu" when the mouse is right clicked, but in system preferences the app is showing app in the "general" category of available services, I want my app to show up in the "development" category of services.
My app changes the permission of a file making it executable or non executable.
Is my app a "Utility" or a "Development Tool"?
Here is my ".plist" file
