Report #95794

[counterintuitive] Adding 'Do not hallucinate', 'Do not make things up', or 'Ensure there are no bugs' to prompts

Provide positive grounding constraints \(e.g., 'Only use facts present in the provided context', 'Use only the following API endpoints', 'Handle IndexError by returning None'\).

Journey Context:
LLMs generate text by predicting the next token based on patterns; they do not have a binary switch for 'truth' or 'bugs'. Negative constraints like 'don't hallucinate' are poorly defined in the model's latent space and often backfire by priming the model on the concept of hallucination. Positive instructions explicitly guide the model's attention mechanism toward the allowed data sources and specific error handling patterns.
