Did you find out if it actually fixed the issue? I was on the other end of this last week. Reported an issue to another team, they asked Claude to diagnose, and when they gave me the response back I pushed back cause it didn’t make sense given the behavior we were seeing. Turns out Claude had hallucinated reading a log (it said it did but it didn’t). Sent it down a hole rabbit hole from there.
I’ve had the one shots you describe and they’re great, but they’re the happy path and require almost 0 skill to find. I’ve yet to see a case where developing an expert level knowledge of your domain isn’t the best way to get good at LLMs. Knowledge of how to interface with these tools is helpful but changes (and depreciates) rapidly as the models get smarter and/or other people commoditize it. Deep subject knowledge is still the best way to get a lot out of these tools. This applies to development and other areas I have a deep knowledge of.
“LLM training” is kinda snake oil. Learn your craft deeply and you’ll be able to catch up on LLM training in a few days, but you’ll be light years ahead of a person who’s only expertise is different ways to prompt.
