System Prompt Security for Products (EXPLAINED)
Protect instructions, secrets, policy, and tool policies in system prompts against leakage, override, and indirect injection.
TL;DR — Quick Answer
Never embed secrets in system prompts; assume they can leak. Separate policy from user-visible text, use tool sandboxing, validate outputs, and monitor for extraction attempts. System prompt security is architecture — permissions, data boundaries, and review gates — not clever hidden instructions.
