AI Guidance - How to use AI as a Senior Developer

I've been giving LLMs a chance every year now, and now I think the Agents are finally capable of something, so here's I make some use of AI as a Senior Developer. I'm experimenting a lot so having a technology that might give me a quick implementation of what's in my mind is a game changer. But usually LLMs generates a ton of shit if you don't tell them very specifically what to do, but if you already know what to do exactly, you can implement it yourself 10x faster than any CjAI that goes in circles. It's not a secret here I'm going to expose here that has never been discussed.
