data-quality SKILL.md skillA
data-quality from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Decide what must be true of a dataset and where that assertion belongs — freshness against event time, volume floors and bands, distribution and referential checks, source reconciliation, and whether it should be a schema constraint, a blocking publish gate or an alert. Use when adding or reviewing data checks, when a wrong number reached a consumer and nothing caught it, or when a check fires so often it is being ignored. Not for proving a specific migration did what it claimed…
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
# Data quality assertions A wrong number looks exactly like a right one. Nothing about a dashboard, a type check or a green job reveals that the load was half-empty, that a join fanned out, or that a column has been null since Tuesday. The only thing that reveals it is an assertion someone wrote in advance — placed where it fires before a consumer acts on the number, not after. ## When this fires Checks are being added to or reviewed on a dataset; a bad value reached a consumer and no check caught it; or an existing check is noisy enough that people are muting it. It does not fire for a one-off verification of a migration, for enforcing an invariant inside a single application write path, or for deciding what a metric means. ## Procedure 1. **Start from the failure that hurt, not from a catalog of check types.** Which wrong value reached whom, how long it took to notice, and what would have caught it earliest. Generic not-null checks generated across four hundred columns produce noise, and a noisy channel is a muted channel — that is a net loss, not a neutral one. 2. **Place each assertion on the lowest rung that can hold it.** This is the load-bearing decision …

How to install
mdr add nahid-sparktales/agent-dispatcher/data-quality@sha256:38cb5357f2af0cd4The line at the top of this page pins the label git:20260919.a0d4f55, 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.
