> pglite

You are an expert in PGlite, the lightweight WASM Postgres build that runs in the browser, Node.js, and Deno. You help developers embed a full Postgres instance (with extensions like pgvector, PostGIS) in client-side apps, Electron, React Native, and serverless functions — providing real SQL with JSONB, full-text search, and vector similarity search at ~3MB compressed, without a server.

> 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.

> 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.

> 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.

> xata

Expert guidance for Xata, the serverless data platform that combines PostgreSQL, Elasticsearch, and AI capabilities in a single API. Helps developers build applications with full-text search, vector similarity search, file attachments, and branching — all through a type-safe TypeScript SDK.

> alembic

Manage database migrations with Alembic. Use when a user asks to version database schemas, create migration scripts, handle schema changes in production, or manage SQLAlchemy model migrations.

> 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.

> sqlite

SQLite is a self-contained, serverless, zero-configuration embedded SQL database engine. Learn CLI usage, Node.js integration with better-sqlite3, Python's built-in sqlite3 module, and best practices for schema design, indexing, and WAL mode.

> electric-sql-sdk

You are an expert in Electric SQL, the sync engine that streams Postgres data to local apps in real-time. You help developers build local-first applications where data syncs from Postgres to client-side SQLite/PGlite automatically — enabling instant reads, offline support, and real-time multi-user collaboration using Postgres as the single source of truth with Shape-based partial replication.

> electric-sql

Build local-first applications with ElectricSQL — sync Postgres data to client devices in real-time. Use when someone asks to "sync database to client", "local-first app", "ElectricSQL", "offline-first sync", "real-time Postgres sync", "sync Postgres to SQLite", or "build an app that works offline". Covers shape-based sync, real-time subscriptions, offline support, and conflict resolution.

> nhost

Expert guidance for Nhost, the open-source backend platform built on PostgreSQL, Hasura GraphQL, and serverless functions. Helps developers set up authentication, database, file storage, and real-time subscriptions with auto-generated GraphQL APIs and a developer-friendly SDK.

> owasp-zap

Assists with finding security vulnerabilities in web applications using OWASP ZAP. Use when configuring automated scans, writing scan policies, integrating security scanning into CI/CD pipelines, or analyzing results for OWASP Top 10 vulnerabilities like XSS, SQL injection, and CSRF. Trigger words: owasp zap, security scan, vulnerability scanner, penetration testing, zap-baseline, active scan, passive scan.

> pgvector

Store and search vector embeddings in PostgreSQL with pgvector — no separate vector database needed. Use when someone asks to "vector search in Postgres", "store embeddings", "pgvector", "similarity search", "RAG with Postgres", "semantic search in existing database", or "add AI search to my app without a separate vector DB". Covers vector columns, indexing (IVFFlat, HNSW), similarity search, and integration with ORMs.

> 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.

Build and manage Microsoft Access databases, queries, forms, reports, and VBA automation. Use when someone asks to "create Access database", "write Access queries", "build Access forms", "Access VBA macro", "migrate from Access", "Access report", "link Access to SQL Server", or "convert Access to web app". Covers table design, relationships, SQL queries, forms, reports, VBA automation, and migration strategies to modern platforms.

> sqlalchemy

Work with databases in Python using SQLAlchemy. Use when a user asks to set up a Python ORM, define database models, write async database queries, manage migrations with Alembic, or choose between SQLAlchemy and Django ORM.
