问题 In short I want to create, edit and delete rules from a rules repository at runtime. I'm having trouble figuring out how to do this in drools 6+.

Is it possible to write rules for Drools without using the KIE workbench? Yes, it should support importing rules so all you need to do is open up a text editor and start typing.
