> postgresql

Assists with designing schemas, writing performant queries, managing indexes, and operating PostgreSQL databases. Use when working with JSONB, full-text search, window functions, CTEs, row-level security, replication, or performance tuning. Trigger words: postgresql, postgres, sql, database, jsonb, rls, window functions, cte.

> mysql

MySQL is the world's most popular open-source relational database management system. Learn installation, SQL queries, indexing strategies, replication setup, and client integration with Node.js (mysql2) and Python (mysql-connector).

> prisma

You are an expert in Prisma, the TypeScript ORM with a declarative schema, auto-generated type-safe client, migrations, and studio GUI. You help developers model databases with Prisma Schema Language, generate a fully typed client that catches query errors at compile time, run zero-downtime migrations, and integrate with Postgres, MySQL, SQLite, MongoDB, CockroachDB, and PlanetScale.

> sequelize

You are an expert in Sequelize, the promise-based ORM for Node.js supporting PostgreSQL, MySQL, MariaDB, SQLite, and MS SQL. You help developers define models, build queries, manage migrations, handle associations, use transactions, and configure connection pooling — providing a mature, battle-tested data access layer for production Node.js applications.

> sql-optimizer

Analyze and optimize SQL queries for performance. Use when a user asks to optimize a query, speed up a slow query, analyze a query plan, add indexes, fix N+1 queries, reduce query time, tune database performance, or rewrite SQL for efficiency. Supports PostgreSQL, MySQL, and SQLite.

> sqlmap

Detect and exploit SQL injection with sqlmap. Use when a user asks to test for SQL injection, extract database contents, bypass authentication via SQLi, automate injection testing, or dump database schemas.

> planetscale

Expert guidance for PlanetScale, the serverless MySQL platform built on Vitess (the database clustering system powering YouTube). Helps developers set up databases with Git-like branching for schema changes, non-blocking schema migrations, and connection pooling for serverless environments.

> tinybird

Build real-time analytics APIs with Tinybird — ingest millions of events and query with SQL over HTTP. Use when someone asks to "build analytics API", "Tinybird", "real-time analytics", "event analytics", "ClickHouse as a service", "usage metering", or "product analytics backend". Covers data ingestion, SQL pipes, API endpoints, and real-time dashboards.

> turso

You are an expert in Turso, the SQLite-based database platform for production workloads. You help developers use libSQL (Turso's SQLite fork) as a primary database with features like embedded replicas (SQLite file synced from cloud), multi-region replication, vector search, branching, and edge deployment — providing sub-millisecond reads with the simplicity of SQLite and the durability of a cloud database.

> typeorm

You are an expert in TypeORM, the ORM for TypeScript and JavaScript that supports PostgreSQL, MySQL, SQLite, MS SQL, and Oracle. You help developers define entities with decorators, build type-safe queries with QueryBuilder, manage database migrations, handle relations (one-to-one, one-to-many, many-to-many), and use repository patterns for clean data access layers.

> neon-serverless

You are an expert in Neon, the serverless Postgres platform. You help developers use fully managed PostgreSQL with instant database branching, autoscaling to zero, edge-compatible HTTP driver, connection pooling, and point-in-time recovery — enabling development workflows where each PR gets its own database branch and production scales automatically based on load.

> motherduck

Expert guidance for MotherDuck, the serverless analytics platform built on DuckDB that combines local and cloud query execution. Helps developers run SQL analytics on cloud-hosted data, share datasets, and build hybrid local-cloud data pipelines using DuckDB's familiar interface.

> drizzle-orm

You are an expert in Drizzle ORM, the lightweight TypeScript ORM that maps directly to SQL. You help developers write type-safe database queries that look like SQL (not a new query language), generate migrations from schema changes, and deploy to serverless environments with zero overhead — supporting Postgres, MySQL, SQLite, Turso, Neon, PlanetScale, and Cloudflare D1.

> malloy

Expert guidance for Malloy, the experimental data language from Google that replaces SQL for analytics with a composable, reusable, and more readable syntax. Helps developers write Malloy models, build nested queries, and explore data with Malloy's VS Code extension and notebook interface.

> grafana

Grafana is an open-source visualization and dashboarding platform that connects to dozens of data sources including Prometheus, PostgreSQL, ClickHouse, and Elasticsearch. It lets you build interactive dashboards with panels, set up alerting rules, and manage everything as code through JSON dashboard definitions and provisioning configuration.

> gcp-bigquery

Analyze massive datasets with Google BigQuery. Run SQL queries on petabytes of data, load and stream data in real-time, create materialized views, and use BigQuery ML for machine learning models directly in SQL.

> tinybase

You are an expert in TinyBase, the reactive data store for local-first applications. You help developers build offline-capable apps with structured tables, automatic reactivity, CRDT-based sync, persistence to IndexedDB/SQLite/Postgres, and relationship modeling — providing a complete client-side database that syncs across devices without a custom backend.

> security-audit

Scan code for security vulnerabilities, misconfigurations, and exposed secrets. Use when a user asks to audit security, find vulnerabilities, check for OWASP issues, scan for secrets, review dependencies for CVEs, detect SQL injection, find XSS vulnerabilities, or harden an application. Covers OWASP Top 10, dependency auditing, secrets detection, and generates fix recommendations with severity ratings.

> aws-rds

Manage Amazon RDS for fully managed relational databases. Provision MySQL, PostgreSQL, and Aurora instances with automated backups and patching. Configure read replicas for scaling, snapshots for recovery, and Aurora Serverless for variable workloads.

> hasura

Expert guidance for Hasura, the GraphQL engine that gives the agent instant, real-time GraphQL APIs over PostgreSQL (and other databases). Helps developers set up Hasura, configure permissions, write custom business logic with Actions and Event Triggers, and optimize GraphQL queries for production.
