How to make mate connectors on specific entities in a context?

Hello, I am making my first featurescript and I've been trying to figure out how to make a sketch on one of a line's mate connectors, and I'm wondering if there's an easier method. I need a sketch's plane to be perpendicular to the plane of another sketch so that I can revolve a ridge around a cylindrical pin, basically I need the sketch's plane to always cut the pin head in half, how could I go about doing this?

I want to make a feature like what happens in the first part studio to the cylinder pin, "Tab Connection Testing." The sketch I am referring to is "sketchR," the feature-script needs to take the top face of a pin head, make a ridge around it, cut an X slot into the pin from top-down so each tab can flex in, and also cut a ridge around the inside of the yellow part's slot so the tabs can snap into it.

It looks like you have all of the vectors needed to construct a plane that divides the pin head in half. It is possible to just create a manual plane sending the following arguments plane(origin, normal, x);

Personally, I avoid using sketches in FeatureScript (too much math ). If you know you'll always be working with a cylinder when using the feature, you can make some assumptions and instead of building a sketch, just model a configurable part in another Part Studio and use it as a boolean tool (see this example, still needs a bit of tweaking but should show what I'm getting at). You could then do the same for the X-slot as well, maybe do the X-slot as a pure boolean subtract and the ridge as a subtract-complement.

Yep ok, seems I just had to use the sketch coordinate system's origin(credit to the port feature where I found some of the cSys usage), but thanks for the idea about simply inserting a configurable part instead of sketching every part in feature studio, especially for much more complex parts.
