yds-data-validation skillA

yds-data-validation is agent-read markdown (skill) from ymd38/dev-skills: Inspect a project's data for correctness and produce a read-only validation report — record counts, NULL rates, value distribution, uniqueness, referential integrity, format validity, and sampled evidence rows. Data is read only from the project's own test fixtures/seed data or from an explicitly configured connection; never from a guessed or production source. Triggers on requests like "validate the data", "check data quality", "データ検証", "データの妥当性を確認", "NULL率を調べて", "件数がおかしい", "/yds-data-validatio.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add ymd38/dev-skills/yds-data-validation@git:20260820.725a136
Exact content
mdr add ymd38/dev-skills/yds-data-validation@sha256:6bd32e61b32bad9c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
