Your Agent Gave the Right Answer for the Wrong Reason — and You Have No Idea

A practical framework for observability and evaluation of agentic AI systems - built to work on any use case image 1.1 “LLMs are non-deterministic. You can’t really test them.” I heard this in a production review meeting after a multi-agent pipeline we built started returning confident, plausible, and occasionally incorrect answers. Nobody had caught it because nobody was looking at the steps - only the final output. That statement is one of the most dangerous half-truths in AI engineering today. You can’t test LLMs the way you test a sort function.
