Eval Driven Development includes explicit scope boundaries (an explicit 'when not to use' or 'out of scope' section); pricing or quota commentary; at least one code block. At roughly 1,861 words the SKILL.md is on the longer end of the catalog distribution.
Eval Driven Development sits in the Science & Research category under the math-stats sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.
These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.
Eval Driven Development is a community-contributed Claude Code skill in the math-stats sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/eval-driven-development/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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).
The Eval Driven Development Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

SKILL.md from the source repository to ~/.claude/skills/eval-driven-development/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Eval Driven Development is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.
