Trains Claude to write SQL at Staff+ DBA level by targeting the non-obvious patterns Claude's defaults miss. Covers multi-column statistics for correlated predicates, operator class selection for index usage, aggregate FILTER patterns, keyset pagination, and the query anti-patterns that silently destroy production performance. Use when writing complex SQL, reviewing a query for correctness or performance, adding indexes, or optimizing a slow query.
