Trifecta Checker - Blast Radius Zero
Trifecta Checker is an AI Safety Gate that prevents Lethal Trifecta attacks: when an AI agent reads private data (Gmail), fetches untrusted content (malicious URL), and tries to exfiltrate externally. How it works on Vultr: - rules/trifecta-scoring.js calculates open score 0-100: CLEAN/OK/RISKY/DANGER - rules/shield.js implements Blast Radius Zero: If agent has 3+ Lethal attempts in 1 hour, block ALL Vultr VM creation for 24h - Every block returns HTTP 403 and logs to Concordium wallet 3eLK...z44V for on-chain audit Proof on 【entity-AMD¦canonical_name=AMD】 MI300X GPU (Nov 3): Tested on notebooks.【entity-amd¦canonical_name=AMD】.com Agents 101 - Build AI Agent with MCPs using vLLM, Pydantic AI, MI300X.

Trifecta Checker AI Safety Gate for Lethal Agents
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.
