Verify that a SQL query's actual output faithfully answers the natural-language question.
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
# SQL Revision A query that runs is not the same as a query that is right. The goal of revision is to catch the gap — the cases where the SQL executes cleanly but produces an answer that doesn't match what the question literally asks for. Treat your own SQL skeptically: the agent that wrote it has already convinced itself it's correct, and that agent is you. ## Principles - **The literal text of the question is the arbiter.** Not your memory of it, not the plan you wrote, not your reasoning about it. Quote the parts of the question that describe the output and the constraints so you have something concrete to diff against. - **Check the shape before the values.** If the question asks for specific columns in a specific order and your output has different ones, that is a real mistake — do not rationalize it as a naming convention or "extra context." Compare column lists directly. - **Check the constraints individually.** Walk through every filter, grouping, scope, and condition in the question and find where your SQL implements it. If you cannot point to the implementation, the constraint is silently missing. …

How to install
mdr add stringnlplab/flexsql/sql-revision@sha256:4f44a91d7c387ef6The line at the top of this page pins the label git:20260504.f1763a1, 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.
