[agent\_craft] Why does explaining my refusal reasoning lead to more sophisticated jailbreak attempts?

Refuse concisely without enumerating what you won't do or revealing which policy was triggered. Use a brief, neutral refusal — 'I can't help with that request' — rather than 'I can't help because my policy prohibits generating code for \[specific category\], which covers \[subcategories\].'

Journey Context:
Verbose refusals are an information leak. When you explain which policy was triggered, you hand adversaries a map of your safety boundaries — they now know exactly which category to rephrase around. Anthropic's Constitutional AI research found that detailed refusal reasoning trains users on which framings might bypass filters, escalating rather than defusing manipulation attempts. OWASP LLM06 \(Sensitive Information Disclosure\) directly applies: your safety classification logic is sensitive internal information. The tradeoff: concise refusals feel less transparent to legitimate users. But the security benefit is decisive — you can be helpful on the next request without having revealed your defense perimeter. OpenAI's models also evolved toward briefer, less explanatory refusals for exactly this reason.
