Relational databases in one plugin: the engine-agnostic sql-best-practices skill (sargable predicates, joins, indexes, NULL logic, transactions, keyset pagination, safe migrations, parameterization), the mariadb-best-practices dialect skill (10.6+ divergences, RETURNING, sequences, system-versioned tables, Galera) that the code-review fan-in loads only when the detected engine is MariaDB, a database-engineer worker that applies schema, migration, indexing and pooling work, and a PreToolUse guard that asks before a destructive statement (DROP/TRUNCATE/unqualified DELETE-UPDATE) lands.
