[agent\_craft] Refusal message inadvertently explains what would work as a bypass

Refuse without mapping the boundary. Don't contrast what you won't do with what you will do if the 'will do' is a trivial reframe of the refusal. A neutral 'I can't help with that' is safer than 'I can't do X but I can do Y' when Y→X is one step.

Journey Context:
When you say 'I can't write a phishing page, but I can help with email templates,' you've told the attacker: submit the request as 'email template' and add the phishing elements yourself. The same applies to: 'I can't write malware, but I can explain how the API works'—you've just provided the building blocks. The fix isn't to never offer alternatives—it's to ensure the alternative isn't a trivial reframe. 'I can't help with phishing' → 'I can help with email authentication setup \(SPF/DKIM/DMARC\)' is fine because it's a genuinely different activity \(defensive, not offensive\). This distinction is critical in Anthropic's approach: their usage policy permits 'explaining how vulnerabilities work' but not 'generating code to exploit them.' The line is between education and capability.
