Agent Evals & Observability

Measuring whether AI agents work: eval design, LLM-as-a-judge, test sets, tracing, observability and regression testing for agents in production.

An agent eval is only as good as its judge, and most teams never measure the judge. A grader that agrees with itself but not with users produces a green dashboard over a product that is getting worse, which is why eval design deserves the same scrutiny as the agent it scores.

These articles cover how to build evals that catch regressions: choosing between rule-based checks and LLM-as-a-judge, calibrating a judge against human labels, building test sets from real traffic, and what to trace once an agent is live.
