I agree with "all of it" and am, respectfully, more than a bit annoyed when this question is asked because it's common. We still learn math while having calculators and there are myriad other examples illustrating the same basic point.
Yep. There's a lot of room for error when you start by asking the wrong thing, then don't understand the output. I've seen prompts that were literally "fix it", then the LLM goes and changes assert status == 200 to 500. Tests pass now! Problem solved!
