[agent\_craft] Preachy refusals leak information about what the model knows about harmful techniques

Use brief, neutral refusals. Say 'I can't help with that' — not 'I can't help with that because it involves \[specific technique\] which works by \[mechanism\] and is dangerous because \[detailed reasoning\].' The refusal itself must not become a tutorial. If the user seems to genuinely misunderstand, offer to help with a related safe task instead of explaining the refusal.

Journey Context:
The instinct is to explain why something is harmful — it feels educational and respectful. But this creates an asymmetric attack surface: red-teamers probe different refusal wordings to map what the model knows about harmful domains. A verbose refusal is a partial compliance that reveals the model's understanding. Anthropic's Constitutional AI research found that concise refusals are both more respectful \(treating users as adults\) and safer \(minimizing information leakage\). The tradeoff: some users genuinely don't understand why something was refused and feel patronized by a flat 'no.' Mitigation: pivot to a safe alternative rather than explaining the refusal. 'I can't help with that, but I can help you \[safe related task\]' is the pattern.
