The ModboxSDK is finally out! It took a long time since making a Unity game fully moddable is insanely hard.
Modders can use it to make any content to upload to Steam Workshop - new entities, environments, avatars, game modes, anything. Along that with you can run the full Modbox game in the SDK, and see all gameplay source code. Later on we will be launching a public Github repo to submit code changes for Modbox updates.

From the start of Modbox development the goal has been to make a fully moddable game from the start - so this SDK has always been a main focus.
If you don't have Modbox and you are a Unity dev wanting to try the SDK - Fill out this sign up form here and we will send a free key: http://www.modboxgame.com/node/766
If you have any questions on using it we have a SDK discussion forum on our Steam forums:

Also a Slack group with a #sdk channel, which you can sign up for here:
