> 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.

> d1-database

Build serverless applications with Cloudflare D1 — SQLite at the edge. Use when someone asks to "serverless database", "Cloudflare D1", "SQLite at the edge", "database for Workers", "edge database", or "serverless SQL". Covers schema setup, queries, migrations, Workers integration, and Drizzle ORM.

> 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.

> 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.

> 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.

> supabase

Build applications with Supabase as the backend — Postgres database, authentication, real-time subscriptions, storage, and edge functions. Use when someone asks to "set up Supabase", "add authentication", "create a real-time app", "set up row-level security", "configure Supabase storage", "write edge functions", or "migrate from Firebase to Supabase". Covers project setup, schema design with RLS, auth flows, real-time subscriptions, file storage, and edge functions.

> knex

You are an expert in Knex.js, the flexible SQL query builder for Node.js that supports PostgreSQL, MySQL, SQLite, and MSSQL. You help developers write type-safe queries with a chainable API, manage database migrations and seeds, build complex joins and subqueries, and use transactions — providing direct SQL control without the overhead of a full ORM.

> 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.

> 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.

> ibis

Expert guidance for Ibis, the Python dataframe library that provides a pandas-like API but generates SQL for execution on any backend — DuckDB, PostgreSQL, BigQuery, Snowflake, Spark, and more. Helps developers write analytics code once and run it anywhere without rewriting SQL for each database.
