Eval Driven Development

Agent skill
1 skill

Use when reasoning about building language-model-integrated systems by writing evaluations before and alongside the system: the statistical (not binary) nature of LLM evals, the five primitives (dataset, evaluation function, aggregation, iteration loop, regression budget), the judgment-mechanism taxonomy (programmatic, model-graded, human-graded, preference comparison), the difference between system-specific evals and canonical benchmarks (MMLU, HumanEval, BIG-bench, GAIA), how evals drive prompt/model/scaffolding/tooling changes, why Goodhart's Law means higher eval scores are not always improvements, and the offline-eval-vs-production-telemetry distinction. Do NOT use for deterministic unit testing (use testing-strategy), production monitoring (use evaluation or error-tracking), general-software TDD (use testing-strategy), or the construction of individual eval rubrics and task sets (use agent-eval-design — it owns construction; this skill owns the iteration discipline).
