alt Hacker NewsI believe using a skill here is the wrong approach. LLMs already know what TDD is and how to do it, just like object oriented programming.
If this is encoded in a skill, that skill essentially has to be loaded for everything thing your LLM is doing. This is probably one of the few areas where direct instructions via AGENTS.md is best, and I don't believe it requires much direction here to force the issue.
But I think the OP is just trying to have their agent work in a very specific way -- that is fine too.

People forget skill is just a markdown file and I don't think TDD makes sense. It's more for specific niches like working on your custom codebase or some less beaten paths you take and save the lessons going forward
But everybody is free to choose how they work and it may be required in ways that we can't know about.
My experience has been that yes, LLMs already know about TDD, OOP, etc., but they won't necessarily BEHAVE according to what they know unless you tell them. And of course, they "know" a lot of things that conflict with each other.
