My Agent Skill for Test-Driven Development - SaturnCI - Continuous Integration for Ruby on Rails

AI agents tend to be, at least as of this writing, lousy at writing tests. The tests they write are often vague, cryptic, overcomplicated, hacky, disorganized, tautological, performative, perfunctory and downright pointless. Unfortunately, I don't expect uncoached agents to get much better at writing tests anytime soon, because the agents learned by human-written example, and the human-written examples out there are often, I'm sorry to say, just as bad. Not only are the tests written by "amateurs" often poor quality, but, sadly, the testing practices preached by teachers are often pretty bad as well. It's truly rough out there.
