"trifecta-checker team on AMD AI League Hackathon"

Trifecta Checker is an AI safety gate that blocks Lethal Trifecta attacks - the dangerous combination of Private Data + Untrusted Content + External Communication that enables data theft via prompt injection. The problem: AI agents with tools like read_gmail, browse_web, and send_email can be tricked by malicious web content to steal private emails and exfiltrate them. This is called the Lethal Trifecta. Our solution: One API call - POST /api/check-trifecta - analyzes the agent's tool manifest and returns instant verdict: - LETHAL (3/3 tools): 403 Forbidden - BLOCKED - Cannot execute - WARNING (2/3 tools): 200 OK with caution flag - SAFE (1/3 tools): 200 OK - Safe to proceed Live and tested: https://trifecta-checker.vercel.app/ - LETHAL test [read_gmail, browse_web, send_email] -> 403 - WARNING [browse_web, send_email] -> 200 warning - SAFE [read_gmail] -> 200 safe For 【entity-AMD¦canonical_name=AMD】 AI League Match 4 - Intelligent Web Information Retrieval - we extend with Trusted Source Verification: before allowing external communication, we verify web sources are trusted (.gov, .edu, Concordium ID verified). If source is untrusted, block or flag. Tech: Next.js 14 + TypeScript, Vercel Edge, Python/JS SDKs, 【entity-AMD¦canonical_name=AMD】 ROCm ready for LLM inference.
