    Database Schema & Query Review Gate — Catch Slow Queries, Missing Indexes & Risky Migrations Before Prod

    Database Schema & Query Review Gate — Catch Slow Queries, Missing Indexes & Risky Migrations Before Prod

    by PubsProToolkit

    $12

    Review a database schema, queries, or migration for the mistakes that get expensive in production — bad table design, missing or wrong indexes, slow and N+1 queries, SQL injection, and migrations that lock or break prod. Engine-aware (PostgreSQL, MySQL, SQLite, SQL Server), it runs an ordered review and returns a PASS/REVIEW/BLOCK verdict with prioritized fixes. Schema mistakes are the most expensive kind — this catches them before they ship.
