The difference between a demo agent and a production agent is measurement. This section is the definitive reference for every evaluation metric used in real production AI/agent systems — formulas, thresholds, when to calculate, and why each metric matters.

Why this section exists

In FDE interviews, you will be asked to design an evaluation pipeline from scratch. Candidates who can name metrics are common; candidates who can write the formula, state the threshold, and explain when to compute it offline vs. online are rare. This section turns you into the latter.
