I don't see how "two years ago" is incongruous with having been using LLMs for coding, it's exactly the timeline I would expect. Yes, some people do just post "git gud" but there are many people ITT and most of the others on LLM coding articles who are trying to explain their process to anyone who will listen. I'm not sure if it is fully explainable in a single comment though, I'd have to write a multi-part tutorial to cover everything but it's almost entirely just applying the same project management principles that you would in a larger team of developers but customized to the current limitations of LLMs. If you want full tutorials with examples I'm sure they're out there but I'd also just recommend reviewing some project management material and then seeing how you can apply it to a coding agent. You'll only really learn by doing.
