Inspect CSV snapshots, compare chosen summary statistics with source hashes, and publish cleaned source-schema exports with explicit numeric normalization and guarded writes. Use for CSV cleaning and data-backed charts or reports; derived analysis fields stay separate from the cleaned export.
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
Choose the workflow for the requested output. Read its linked instructions before the covered operations; several workflows may apply to one task. Use the supported scripts from the `packagePath` returned by `skill_read`. They use Python's standard library and need no package installation. | Requested work | Instructions and command | | --- | --- | | Clean or publish a CSV | [CSV export](references/csv-export.md): `scripts/csv_export.py inspect` then `export`; preserve source columns and keep derived analysis fields separate. | | Summarize a distribution or identify dated extremes | [Descriptive statistics](references/descriptive-statistics.md): `scripts/numeric_profile.py`; choose the actual fields, transform and record labels. | | Compare periods, groups, levels or changes in a report | [Numeric comparisons](references/numeric-comparisons.md): `scripts/numeric_comparison.py`; prepare the actual cohorts and explicitly choose the statistic. | | Interpret price and volume evidence | [Market data evidence](references/market-data-evidence.md): distinguish descriptive associations from forecasts, causes and liquidity claims. | …

How to install
mdr add ybz21/roami/tabular-analysis@sha256:a7ebb8f61e07af07The line at the top of this page pins the label git:20261101.eae0ac7, 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.
