I made a console tool for Unity because there weren't really any good ones at the time. I went with quake-style for that old-school cool. All the commands are scriptable objects and I made a code generator tool that generates the boiler plate code. The commands are data, so they can be removed from the commands directory, which effectively removes them from the application. The generator also makes adding new commands easy.
It comes with some base commands as you can see. https://assetstore.unity.com/packages/tools/utilities/console-toolbox-129873
Built in entity and scene commands.
