Is anyone writing their own Credo rules?

One of the less-appreciated aspects of Credo is the fact that you can write your own linting rules for it. Is anyone doing this for a project or company, and would be willing to share their experience or rule modules?

For example, I’d love to see if anyone could code up some rules used by the other style guides(like this one or that one) that are either too new or too particular to be in merged into Credo proper. Or if you have your own rules you’ve made, please link them here. :slight_smile:
