Evals
Evals are 53 percent (62 companies), real but middling against the top themes, and the most over-taught topic in the field. The report's verdict is right-size: teach the PM-grade version (define a failure taxonomy, build or commission a gol

Read one hundred real traces before you buy an
Specify what every trace must emit, then sit with a hundred real production traces and let the failure categories emerge before you spend a dollar on eval infrastructure. - 08.02
Name the failure from one taxonomy
Classify each failed run against a single taxonomy, then roll the counts into a frequency-and-severity table engineering can work off. - 08.03
Turn one complaint into thirty golden examples
Grow a single user complaint, or synthetic cases sampled from the spec when there is none yet, into a trustworthy golden set, and judge how many examples you need. - 08.04
Pay for the cheapest evaluator that can see th
You match every failure mode to the least expensive grader that can reliably catch it, from a code assertion up through an LLM judge to a human annotator, so eval spend goes only where cheap graders are blind. - 08.05
Write the criterion
You default every criterion to a binary pass or fail, reach for pairwise or an anchored scale only when a binary genuinely cannot say it, and force the judge to write its reasoning so its biases become visible. - 08.06
Validate the judge
You measure your LLM judge like a classifier against a frozen, human-labeled test set, tracking its true-positive and true-negative rates separately because rare failures make raw agreement a lie. - 08.07
Eval-driven development
You write the failing eval that reproduces a bug before you fix it, then gate the deploy on that suite in CI. - 08.08
Evaluate an agent
You score an agent across three altitudes, outcome, trajectory, and step, and separate pass^k reliability across a whole task from single-run pass@k capability. - 08.09
INTEGRATION CASE
Real failures let you produce a pass rate on held back cases, with pass or fail checks that point to specific fixes.
