How do you separate policy enforcement from model style instructions?

Instruction: Describe how you keep policy from becoming just another prompt preference.

Context: Separating presentation instructions from enforceable permissions.

Example Answer

Style instructions shape how the model speaks. Policy enforcement shapes what the system is allowed to do or reveal. Those should not live in the same fragile place if the business depends on them differently.

I prefer policy enforced through orchestration, tool controls, validation, and dedicated safety logic where possible, while the prompt handles tone, format, and interaction style. If a critical rule exists only as a polite instruction in the prompt, it is too easy for adversarial or noisy context to weaken it.

Separation matters because policy is a control boundary. Style is a presentation preference.

Concrete example

A prompt can ask for concise wording. The refund endpoint must independently check account access, amount limits, and approved scope even when the assistant asks confidently for an exception.

Limit to explain

Deterministic enforcement fits explicit permissions and action limits. Semantic policy judgments may still need classifiers or qualified review; neither is infallible.
