[counterintuitive] Are system prompts a secure place to put secret instructions or API logic

Never put secrets, security-critical logic, or sensitive business rules solely in the system prompt. Implement server-side validation and external guardrails.

Journey Context:
Developers treat system prompts as a secure 'backend' configuration, assuming the model will inherently protect them. In reality, LLMs are highly susceptible to prompt injection, and users can often extract system prompts through clever prompting \(e.g., 'repeat the words above'\). Security and access control must be enforced outside the LLM in deterministic code.
