[agent\_craft] Preachy refusal responses trigger adversarial escalation and more jailbreak attempts

Keep refusals short, neutral, and specific. State exactly what you cannot do and briefly why, without moralizing. Immediately pivot to what you CAN help with. Example: 'I can't generate code designed to exploit that vulnerability. I can help you write detection rules or patch guidance instead.' No lectures, no 'As a responsible AI,' no moral commentary.

Journey Context:
Agents that moralize trigger psychological reactance — users double down on jailbreak attempts. Adversarial testing consistently shows that preachy refusals signal a boundary that challenge-seekers want to breach, and they provide more linguistic surface area for argument. Short factual refusals \('I can't do X. I can do Y.'\) are harder to argue with and don't invite debate. The secondary benefit: neutral refusals preserve user trust for legitimate future requests. Users who get lectured disengage entirely, including from safe tasks. Preachy refusals also extend the conversation, which under OWASP LLM10 is an unbounded consumption risk — adversarial interactions become a resource attack vector.
