[agent\_craft] Over-explaining refusals leaks safety logic and creates attack surface

Refuse concisely with a single, neutral sentence. Never enumerate what you won't do, never explain your safety training, never list the categories of harm you're avoiding. Say 'I can't help with that' not 'I can't help with that because my guidelines prohibit assistance with X, Y, and Z which are defined as…'

Journey Context:
The instinct to explain refusals feels respectful but is counterproductive. Each clause in an explanatory refusal is a probe result—attackers map your boundaries by reading your refusal reasons, then craft payloads that sidestep the named categories. Anthropic's Constitutional AI research found that concise refusals reduce reattack rates because they provide less gradient. Preachy refusals also antagonize legitimate users who then share workarounds. The hardest lesson: silence about your safety logic IS the safety logic.
