Frequently Asked Questions
What is indirect prompt injection?
Indirect prompt injection occurs when untrusted external text (e.g. from a webpage, email, or database record) contains adversarial instructions designed to hijack the model behavior.
Are system prompt guardrails 100% foolproof?
While robust prompt guardrails stop the majority of casual and automated attacks, defense-in-depth requires combining prompt instructions with input validation, output parsing, and least-privilege tool access.
