Report #64304

[counterintuitive] system prompts securely hide instructions from end-users

Never put secrets or critical business logic that must remain hidden in system prompts; implement security controls at the application layer, not the prompt layer.

Journey Context:
Developers treat system prompts as a secure vault for proprietary logic. LLMs are inherently text-completion engines; clever user inputs \(prompt injections\) can easily instruct the model to repeat its system prompt verbatim or ignore previous instructions. Security and access control must be enforced outside the model's generative path.
