live · production-grade eval harness

The eval harness behind
50+ shipped AI agents.

Paste any prompt or LLM output. In seconds you get a ship verdict, a 0–10 production score, 5 adversarial probes that try to break it, the single highest-leverage fix, and a production-hardened rewrite you can paste in. This is the exact rubric I run on agents in production at Ema — now pointed at yours.

      This is the work I do — at scale.
      
        
      This lab runs a compact version of the evaluation system I built to keep 50+ AI agents trustworthy enough to ship at Ema. If your AI product needs a rigorous eval layer before it goes live, that's exactly my lane.
