[research] Flipping boolean logic or negation conditions when translating natural language to code

Explicitly double-check negations \(not, except, unless\) and boolean flags \(is\_active vs is\_inactive\) during code generation. Write out the truth table or assert statements if the logic is complex.

Journey Context:
LLMs struggle with negation in natural language. A prompt saying 'Do not include deleted items' might result in 'if \(item.deleted\) \{ include\(\) \}' because the model processes the semantic association between 'deleted' and 'items' without properly applying the negation operator. This is a subtle but catastrophic factual/logical hallucination. Slowing down the reasoning process for negated conditions prevents this.
