Prompt injection scan and content security check before an agent INGESTS external content (SKILL.md, web page, user input, tool output): detects prompt-injection, data exfiltration, dangerous code execution, hidden/invisible unicode and instruction overrides — 0-100 risk score + SAFE/WARN/BLOCK verdict + structured findings with matched evidence. A fast, cheap, deterministic pre-ingest firewall / skill-audit / untrusted-content security check for AI agents.
