Report #102659

[synthesis] Generated output is wrapped in unsolicited disclaimers and offers to help further

Add a negative constraint to the system prompt: 'Do not add disclaimers, safety warnings, or offers to help further unless the user explicitly asks.' Positive-only instructions like 'be concise' are not enough.

Journey Context:
Claude in particular adds caveats in sensitive domains \(legal, medical, security, financial\) more readily than GPT-4o or Kimi. The model's safety fine-tuning nudges it toward hedging. A direct negative constraint in the system prompt consistently suppresses the behavior better than vague brevity requests.
