[counterintuitive] Are system prompts secure against user manipulation

Never put secrets in system prompts and assume they can be extracted; use external guardrails and access controls for security, not prompt hierarchy.

Journey Context:
Developers treat system prompts as a secure, hidden boundary. However, LLMs are highly susceptible to prompt injection, and system prompts can often be extracted via clever user inputs \(e.g., 'repeat the words above'\). Security through prompting is fundamentally flawed because the model doesn't have a true concept of privilege separation; it just predicts the next token based on the entire context.
