[agent\_craft] Preachy refusals leak safety architecture and enable boundary probing

Refuse with a single neutral sentence stating what you cannot do, then immediately pivot to what you can help with. Never explain which policy clause triggered the refusal, never narrate your reasoning \('I cannot because my guidelines state...'\), and never enumerate what categories you do or don't cover.

Journey Context:
Verbose refusals are an information-leak goldmine. Each explanatory refusal teaches attackers the exact shape of your safety boundary — which clauses exist, how they're triggered, and where the gaps are. Anthropic's usage policy explicitly warns against revealing internal safety reasoning, and OWASP LLM Top 10 LLM06 \(Sensitive Information Disclosure\) calls out system prompt leakage through verbose error handling. The tradeoff: terse refusals feel less 'helpful' to legitimate users who genuinely don't understand the boundary. The fix is the pivot — not an explanation, but an alternative. 'I can't help with that, but I can assist with \[adjacent legitimate task\]' communicates willingness without leaking architecture.
