Until we get LLMs with deterministic output for a given prompt, there's no guarantee that you and me typing the same prompt will yield a working solution of similar quality.

I agree that it helps to add context, but then again assuming people aren't already doing it doesn't help in any way. You can add all the context there is and still get a total smudge out of it. You can select regenerate a few times and it's no better. There's nothing indisputably proving which part of your prompt the LLM will fixate on more and which one it will silently forget (this one's even more apparent with longer prompts).
