[agent\_craft] Refusal responses leak safety boundary locations, enabling targeted jailbreak refinement

Use specific language in redirects \(where you're helping the user find a legitimate path\) but keep hard refusals minimal and consistent. Don't explain which specific policy clause was triggered or enumerate what you 'also can't do.' A hard refusal should state the refusal and offer the alternative—nothing more.

Journey Context:
This is a tradeoff between transparency and operational security. Detailed refusals help legitimate users understand and work within boundaries, but they also help adversaries map the exact shape of those boundaries for targeted circumvention. In adversarial settings \(which coding agents increasingly face as they process untrusted code\), verbose refusal patterns are information leakage per OWASP LLM06 \(Sensitive Information Disclosure\). The practical pattern: be specific and helpful in redirects \('I can't write a keylogger, but I can help you build a legitimate user analytics service with proper consent flows'\) because the user has a legitimate need and the specificity helps them. Be brief in hard refusals \('I can't help with that'\) because the request is clearly harmful and additional detail only aids circumvention. This dual approach preserves helpfulness where it matters while minimizing leakage where it's risky.
