CSSketch is a Sketch 3 plugin that enables you to modify your designs quickly by attaching it a stylesheet to it that you can use to lay out your designs, change colors and shadows quickly, etc. It supports {less} stylesheets, which means you can put functions and variables in your stylesheet to make your workflow even more efficient.
CSSketch is completely open source.
To enable CSSketch you must run the menu bar option every time Sketch 3 launches. You can find it on the menu bar at Plugins -> CSSketch -> Layout Layers.
