In this case, sorry to say but it sounds like there's a tooling issue, possibly also a skill issue. Of course you can just use the raw ChatGPT web interface but unless you seriously tune its system/user prompt, it's not going to match what good tooling (which sets custom prompts) will get you. Which is kind of counter-intuitive. A paragraph or three fed in as the system prompt is enough to influence behavior/performance so significantly? It turns out with LLMs the answer is yes.
