The actual "prompting trick" that dramatically improves your results is often to add just two or three words, like "use library foo", "write in <language>", "<bar> algorithm". To know which two or three words apply in your situation, you need a deep understanding of both the problem and the solution space.

Your prompt might look almost the same as the one from somebody with a good understanding of the requirements but no technical competency, plus maybe one or two sentences. Those one or two sentences dramatically change the results, and what those sentences are differs from prompt to prompt.
