This is where you'll find all unofficial contributions to the Sphere Studio. Anyone can ask to have their plugin featured here via pull request.
Create a clone of this repository. Then create a new .Net project targeting .Net 4.0 or higher. Link up the two dependencies found in the /Core folder. These provide the backbone for interacting with the host and Sphere-related files. Make sure to include any third-party libraries via NuGet in your solution, if not include them somewhere inside it. See the FastScriptPlugin as an example.
Then you can follow the plugin tutorial here: https://github.com/Radnen/spherestudio/wiki/How-to:-Plugins
Tip: Copy the Base Plugin and use it as your base for a plugin. That's why it's there!
