version-dataset SKILL.md skillA
version-dataset from aperivue/medsci-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add aperivue/medsci-skills/version-dataset@git:20261002.b489aaePins git:20261002.b489aae in mdr.lock. Pin the fingerprint instead.

Use when you must prove an analysis ran on the intended data or lock a dataset version. Builds a deterministic content-hash manifest (file SHA-256, schema, per-column value hashes), verifies later copies against it for drift, and diffs two manifests.
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
# Version Dataset Skill
An analysis must run on the data it claims to, with a fixed seed. This skill makes drift between
runs loud instead of silent: it records a deterministic fingerprint (file SHA-256 plus, for
tabular files, schema and per-column value hashes; no timestamp unless explicitly passed) so a
later run can *prove* the inputs are unchanged. It never alters data, and manifests hold hashes,
not the data itself. Provenance notes are in English.
## Deterministic Script
```bash
# Build a manifest (record the analysis seed + provenance)
python "${CLAUDE_SKILL_DIR}/scripts/version_dataset.py" manifest data.csv \
--out manifest.json --seed 42 --provenance "KNHANES 2018 extract v1"
# Verify a later copy against it (CI / pre-analysis gate)
python "${CLAUDE_SKILL_DIR}/scripts/version_dataset.py" verify --manifest manifest.json --strict
# Compare two manifests (what changed between versions)
python "${CLAUDE_SKILL_DIR}/scripts/version_dataset.py" diff --old v1.json --new v2.json
```
File hashing is stdlib-only; tabular schema/column hashing uses pandas when present.
`--ignore-cols` excludes volatile columns; `--base` makes manifest keys relative.
## Workflow
…Read the whole file at its exact version.
How to install
mdr add aperivue/medsci-skills/version-dataset@sha256:0e7532398e186740The line at the top of this page pins the label git:20261002.b489aae, 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.
