You're seeing the "front-end" of it. Your job is only to pick what is being injected and where (including the ground, relationship panel, and phone).
There is no way I would release it right now. I need to not only read more about developing professional APIs to fine-tune it looks, but I haven't ported my mod fully on to it yet. Behind the scenes, besides a utility to manage game resources, there is the known code for injecting into objects and such. You already have what is needed.
The reason I sent you my code is to look at the "is_valid" function. It contains everything you need. Get object tags and then check if they have that tag. In my case, I made an Enum using Maxis interface (which works pretty much like in Python 3.4) to list all of the tags in the game, but you can just compare a raw number from the tags list I've mentioned before.
My code doesn't make anything work by magic, it's just to make it clean and easy. :D
