## TL;DR

HELM-style evaluation helps agents reason about scenario coverage, metric plurality, and standardized model comparison rather than a single leaderboard score.

## Core Explanation

An LLM evaluation result is only meaningful when the scenario and metric match the decision being made. Accuracy on a knowledge task does not prove robustness, calibration, fairness, toxicity behavior, efficiency, or domain suitability.

Agents should record the HELM scenario, adaptation method, model version, inference settings, metrics, confidence intervals or uncertainty notes, and missing capability areas. A responsible recommendation explains what the benchmark covers and what it leaves untested.
