The registry for agent skills.
Reviews a database for schema, indexing, query performance, and migration-safety problems, explains each one in plain language, then fixes them on request — and designs a new schema from scratch when there is nothing to review yet. Covers PostgreSQL, MySQL/MariaDB, SQLite, MongoDB, and Supabase, plus Prisma, Drizzle, TypeORM, Mongoose, Django ORM, SQLAlchemy, ActiveRecord, Hibernate, and EF Core. Use whenever the user asks to review, audit, or improve a database or schema; asks why a query, page, or endpoint is slow; mentions missing indexes, N+1 queries, table scans, or a migration that locked a table; asks how to model or structure data for a new feature; asks whether their schema is right before they have real users; or has an AI-generated schema they do not fully understand. Also use proactively when writing or editing migrations, schema files, or ORM model definitions.
