[counterintuitive] System prompts securely isolate and protect instructions from user manipulation

Never put secrets or critical security logic in system prompts; implement external guardrails and validation layers to enforce safety and prevent prompt injection.

Journey Context:
Developers treat system prompts as a secure 'admin' channel. In reality, LLMs do not natively distinguish between system and user tokens at an architectural level—they are just prefixes. Prompt injection attacks easily bypass system instructions by manipulating the model's attention to prioritize the user's malicious payload over the system's directives. System prompts are suggestions, not security boundaries.
