Zambo Stack — Detect prompt injection, jailbreaks, and policy bypass attempts before they reach your AI model. Two-phase analysis: instant pattern library scan (12 attack vectors) + Groq semantic analysis. Returns injection_risk 0–100, recommendation safe/review/block, and a safe rewritten version when possible. 50 free/day. Best for: 'validate user input before LLM call', 'detect jailbreak attempts', 'is this prompt safe to send to GPT?'. When to use: call prompt_shield when the user's request matches this capability. When not to use: do not call it for unrelated work, missing required inputs, or when a safer read-only route is more appropriate.
