What it does
A careful, read-only plan for answering a business question from your warehouse, or a review of SQL you already wrote. It catches wrong joins and privacy slips before they reach a report. The skill starts by pinning down the decision behind the question, the group, metric, dimensions and time window, and what the warehouse allows. Then it checks the query for grain mismatches, join fan-out that inflates totals, bad filters and small groups that could expose individuals. It records scope, data freshness, assumptions and source tables so someone else can repeat the work. It does not change data, fix pipelines or grant access, and the write up avoids claiming more than the evidence shows.
