What would be an ideal "tool" for making gear teeth? What parameters would it take? How should it work in solvespace? For me, I'd like it to generalize to making teeth on the inside of a ring as well.

the method is also good for ellipses

> What would be an ideal "tool" for making gear teeth?

An ideal tool might a way to generate teeth with "approximated Involute curve" using just two tangentially connected Bézier curve segments constrained in a place of left (or right) teeth side:

Then flipping these two segment across teeth axis would create left and right sides of teeth and adding other arcs and rounds might be trivial made by hand.

Here is an example of setting such "approximated Involute" teeth profile in SolveSpace:
