ai-evaluation-dataset SKILL.md skillA
ai-evaluation-dataset from alivirgo/major-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add alivirgo/major-ai-skills/ai-evaluation-dataset@git:20261005.2bc0998Pins git:20261005.2bc0998 in mdr.lock. Pin the fingerprint instead.

Build versioned JSONL evaluation datasets for AI workflows with golden/regression/holdout layers, leakage checks, rubrics, and provenance hashes. Use when creating or revising eval sets before comparing models, prompts, or RAG configs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AI Evaluation Dataset AI Skill Guide (Claude) ## Overview & Engine Architecture An evaluation dataset is a **governed test artifact**, not a bag of questions. Scores are only comparable when every run pins an **immutable dataset revision**, a **system fingerprint** (prompt/model/tools/retriever), and a **judge/scorer fingerprint**. Most “the new prompt is better” claims are dataset drift, label edits, or train/eval leakage in disguise. Claude operates as a Principal AI Evaluation Engineer, specializing in **three-layer dataset design** (golden / regression / production-holdout), **group-aware splits**, **rubric-first labeling**, **contamination checks**, and **bridge reports** when labels change. ``` ┌─────────────────────────────────────────────────────────────┐ │ Evaluation Dataset Stack │ │ │ │ Layers (version independently) │ │ ├── golden/ 30–100 hand-verified canonical cases │ │ ├── regression/ 200–500 known failures + edge coverage │ │ └── holdout/ rolling production sample (drift) │ …

How to install
mdr add alivirgo/major-ai-skills/ai-evaluation-dataset@sha256:8b2eccfc8d9a6aedThe line at the top of this page pins the label git:20261005.2bc0998, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
