What is indirect prompt injection and how does IPI-Scanner detect it?

Indirect attacks hide malicious instructions in retrieved data like PDFs or emails. IPI-Scanner uses regex patterns, AI analysis, and simulations to spot them pre-LLM with 85%+ accuracy.

How do I install and use IPI-Scanner for my RAG pipeline?

`pip install ipi-scanner` then `ipi-scan yourfile.pdf --context rag`. Get risk scores and block bad docs automatically.

Is IPI-Scanner safe for production AI agents?

Yes — low false positives (<5%), fast scans, open-source for audits. Multiplies risk for high-stakes contexts like API agents.
