For designing n8n workflows and nodes, see n8n-workflow.

> socketio

Add real-time communication with Socket.IO. Use when a user asks to build real-time features, add WebSocket communication, build a chat application, implement live notifications, create collaborative editing, stream live data, build real-time dashboards, add presence indicators, or implement pub/sub messaging in a web app. Covers server setup, client connection, rooms, namespaces, authentication, scaling with Redis adapter, and Next.js integration.

> mongodb

Assists with designing document schemas, building aggregation pipelines, managing indexes, and operating MongoDB clusters. Use when working with flexible schemas, nested documents, horizontal scaling, Atlas Search, or vector search for AI applications. Trigger words: mongodb, mongo, document database, aggregation, atlas, nosql.

> retool

Build internal tools with Retool, the low-code platform. Use when a user asks to create admin panels, connect to databases or APIs, build CRUD interfaces with drag-and-drop components, or deploy Retool apps.

> dokploy

Expert guidance for Dokploy, the open-source, self-hosted Platform as a Service alternative to Vercel, Netlify, and Heroku. Helps developers deploy applications, databases, and services on their own VPS with automatic SSL, Docker-based isolation, and a web dashboard for management.

> 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.

> rocket

You are an expert in Rocket, the ergonomic Rust web framework that makes building web applications feel effortless. You help developers build type-safe HTTP APIs with Rocket's macro-based routing, request guards for authentication, form handling, JSON support, database integration, and fairings (middleware) — providing Rails-like productivity with Rust's compile-time safety guarantees.

> superset

Apache Superset is an open-source data exploration and visualization platform. Learn Docker deployment, database connections, chart creation, dashboard building, SQL Lab usage, and programmatic access via the REST API.

> redis

Build applications with Redis — caching, session storage, pub/sub, streams, rate limiting, leaderboards, and queues. Use when tasks involve in-memory data storage, real-time messaging, distributed locking, or performance optimization with caching layers.

> trieve

Expert guidance for Trieve, the all-in-one search infrastructure that combines full-text, semantic, and hybrid search with built-in RAG capabilities. Helps developers implement production search with chunking, re-ranking, recommendations, and analytics without managing vector databases or embedding models.

> 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.

> realtime-database

When the user needs to design database schemas and queries optimized for real-time applications. Use when the user mentions "chat database," "message storage," "real-time sync," "message history," "unread count," "cursor pagination," "event sourcing," or "live data." Handles schema design for messaging, activity feeds, notifications, and collaborative apps with efficient pagination and sync. For WebSocket transport, see websocket-builder.

> 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.

> redis-om

You are an expert in Redis OM (Object Mapping), the high-level client for working with Redis as a primary database. You help developers define schemas, store JSON documents, perform full-text search, vector similarity search, and build real-time applications — using Redis Stack's JSON, Search, and Vector capabilities through an ORM-like interface instead of raw commands.

> mongoose

You are an expert in Mongoose, the elegant MongoDB object modeling library for Node.js. You help developers define schemas with validation, build queries with a fluent API, use middleware hooks, populate references, create virtual fields, and handle transactions — providing structure and type safety on top of MongoDB's flexible document model.

> victoriametrics

Deploy and configure VictoriaMetrics as a high-performance time-series database for metrics storage and querying. Use when a user needs a Prometheus-compatible long-term storage backend, wants to write MetricsQL queries, configure vmagent for metrics scraping, or set up VictoriaMetrics cluster mode for horizontal scaling.

> web-scraper

Extract structured data from web pages and load it into databases. Use when a user asks to scrape a website, build a data pipeline, extract data from a webpage, pull prices from a site, collect links, gather product listings, download page content, parse HTML, set up ETL, or automate data collection. Handles static HTML, JavaScript-rendered pages, anti-bot proxies (Bright Data), data transformation, deduplication, and database loading.

> render

Expert guidance for Render, the modern cloud platform for deploying web applications, APIs, databases, and background workers. Helps developers configure Render services using `render.yaml` Infrastructure as Code, set up auto-deploy from Git, manage environment variables, and optimize for production workloads.

> 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.
