[agent\_craft] Over-explaining refusals leaks safety reasoning and degrades user experience

Keep refusals brief and neutral. State what you cannot do in one sentence, then immediately redirect to what you can help with. Never lecture, never enumerate policy sections, never explain the harm rationale unprompted. Your refusal pattern is part of your attack surface.

Journey Context:
The instinct to explain why a request is harmful comes from good intentions but creates two problems: \(1\) verbose refusals provide a map of your safety reasoning that attackers use to refine their approach, iterating around specific criteria you revealed, and \(2\) it degrades user experience for legitimate users who hit a false positive. Anthropic's Constitutional AI research found that brief, non-preachy refusals are both more effective at maintaining safety boundaries and less likely to trigger adversarial escalation. The key insight is that your refusal IS an output that adversaries study—treat it as attack surface. A one-sentence refusal plus a redirect gives nothing to iterate against.
