[counterintuitive] Instructing the model 'Do not hallucinate' or 'Ensure there are no errors'

Define what constitutes a valid answer, explicitly permit 'I don't know', and provide a grounding context with strict citation rules.

Journey Context:
Negative constraints \('don't do X'\) are poorly handled by LLMs; attention mechanisms focus on the negative concept itself. Telling a model not to hallucinate doesn't give it a mechanism to know the boundary of its knowledge. The fix is to define the positive behavior: 'Answer only using the provided text. If the text doesn't contain the answer, say Insufficient information.'
