Use when reviewing SQL that affects reporting, metrics, transformations, financial logic, product logic, or stakeholder-facing outputs -- especially when a query still runs fine but its business meaning may have drifted.
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
## Purpose Review SQL as business logic, not just syntax. Detect silent semantic changes and flag places where technically valid SQL can still produce wrong business results. ## When to Use - Reviewing SQL changes that feed reports, metrics, or financial/product logic - A query was modified and downstream numbers shifted, or might have - Output looks plausible but the definition of what is being counted may have changed ## Inputs - The SQL under review (diff preferred, full query otherwise) - The intended grain and business definition, before and after the change ## Workflow 1. **Establish the intended grain** before and after the query or change. 2. **Scan for the standard risk patterns:** - grain mismatches - duplicate rows introduced by joins - incorrect join keys - left vs inner join behavior changes - filters that alter population definitions - null handling that changes meaning - default values that hide data quality issues - aggregation mistakes - window functions with unsafe partitions or ordering - date logic and timezone assumptions - incremental logic that can double count, miss rows, or drift …

How to install
mdr add yeaight7/agent-powerups/sql-business-logic-review@sha256:db9058868e2665e1The line at the top of this page pins the label git:20260605.e787b66, 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.
