[counterintuitive] Using negative constraints like 'Do not hallucinate' or 'Do not write buggy code'

Replace negative constraints with positive, verifiable constraints and explicit failure modes to avoid.

Journey Context:
Models are trained on human text, which includes 'do not make mistakes' as a common phrase, but RLHF doesn't map 'don't hallucinate' to a specific internal circuit. It just increases the model's anxiety-like behavior, often making it overly cautious or sycophantic. Instead of saying 'don't use deprecated APIs,' say 'use API version X.Y'. Instead of 'don't hallucinate,' say 'only use the provided context; if the answer is not in the context, state Not found'.
