audit-dataset SKILL.md skillA
audit-dataset from pku-yuangroup/openai4s is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Audit tabular datasets before analysis or training for schema drift, missing values, duplicate rows or IDs, target imbalance, and entity or group leakage across splits using pure-stdlib helpers.
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
# Audit a dataset
Use this skill before statistics, model training, or external publication. The
goal is a compact, machine-readable audit plus explicit decisions about every
issue that could invalidate downstream results.
## Workflow
1. Load records without silently coercing values. Preserve source row IDs.
2. Call `audit_rows` on a representative or complete list of row mappings.
3. Inspect missingness and observed type mixtures column by column.
4. Resolve duplicate records and non-unique identifiers deliberately.
5. If a split column exists, check both stable IDs and grouping entities for
train/validation/test overlap.
6. Record accepted exceptions, then rerun the audit and save the JSON result
next to the cleaned dataset.
## Import and run
Hyphenated Skill directories are loaded with `importlib`:
```python
from importlib import import_module
audit_rows = import_module("audit-dataset.kernel").audit_rows
report = audit_rows(
rows,
target="label",
id_columns=("sample_id",),
group_columns=("patient_id",),
split_column="split",
)
```
`rows` must be a sequence of mappings. The report contains row and column

How to install
mdr add pku-yuangroup/openai4s/audit-dataset@sha256:ae890673ebdcddf1The line at the top of this page pins the label git:20260828.e9753be, 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.
