Use when working on Blazor Web Apps, Razor Pages, MVC, Minimal APIs, controller-based Web APIs, SignalR, gRPC, middleware, dependency injection, configuration, authentication, authorization, testing, performance, deployment, or ASP.NET Core upgrades.

> crawl4ai

You are an expert in Crawl4AI, the open-source web crawler built for AI applications. You help developers extract clean, structured data from websites for LLM training, RAG pipelines, and content analysis — with automatic markdown conversion, JavaScript rendering, CSS-based extraction, LLM-powered structured extraction, and session management for multi-page crawling.

> opa

Expert guidance for OPA (Open Policy Agent), the CNCF policy engine for unified authorization across the stack. Helps developers write Rego policies for Kubernetes admission control, API authorization, infrastructure-as-code validation, and data filtering — enforcing security policies as code.

> reddit-readonly

Browse and search Reddit via the public JSON API with no authentication required. Use when a user asks to read Reddit, browse a subreddit, fetch Reddit posts, get Reddit comments, search Reddit for posts, check trending topics on Reddit, read a Reddit thread, or pull content from a subreddit.

> 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.

> step-ca

Run a private certificate authority with step-ca. Use when a user asks to issue internal TLS certificates, set up mTLS between services, create a private PKI, or manage certificates for internal infrastructure.

> sendgrid

Send transactional and marketing emails with SendGrid. Use when a user asks to send emails programmatically, set up transactional email delivery, send bulk marketing emails, manage email templates, track email opens and clicks, set up email authentication (SPF/DKIM/DMARC), handle bounces and unsubscribes, or build email infrastructure. Covers single and bulk sending, dynamic templates, email validation, webhooks, and deliverability setup.

> auth-implementation-patterns

Master authentication and authorization patterns including JWT, OAuth2, session management, and RBAC to build secure, scalable access control systems. Use when implementing auth systems, securing APIs, or debugging security issues.

> adonisjs

Build full-stack web applications with AdonisJS — a batteries-included Node.js framework with ORM, auth, validation, and mailer built-in. Use when someone asks to "build a web app with Node.js", "Laravel for Node.js", "full-stack Node framework", "AdonisJS", "batteries-included backend", or "Node.js with built-in ORM and auth". Covers Lucid ORM, auth (sessions, tokens, social), VineJS validation, Edge templates, and deployment.

> agent-memory

Add persistent memory to AI coding agents — file-based, vector, and semantic search memory systems that survive between sessions. Use when a user asks to "remember this", "add memory to my agent", "persist context between sessions", "build a knowledge base for my agent", "set up agent memory", or "make my AI remember things". Covers file-based memory (MEMORY.md), SQLite with embeddings, vector databases (ChromaDB, Pinecone), semantic search, memory consolidation, and automatic context injection.

> notion

Build integrations with the Notion API — databases, pages, blocks, comments, search, and OAuth. Use when tasks involve reading or writing Notion workspace data, syncing external tools with Notion databases, building dashboards from Notion content, or automating page creation and updates.

> pipedream

You are an expert in Pipedream, the workflow automation platform built for developers. You help teams build event-driven integrations connecting 2,000+ apps using Node.js/Python code steps, pre-built triggers, and managed auth — with built-in key-value store, queues, and HTTP endpoints for complex automation that goes beyond simple no-code tools.

> websocket-builder

When the user wants to build real-time features using WebSockets. Use when the user mentions "WebSocket," "real-time," "live updates," "socket," "ws," "push notifications," "live chat," "streaming data," or "bidirectional communication." Covers server setup, room management, authentication, reconnection handling, and scaling with Redis pub/sub. For data persistence, see realtime-database.

> composio

You are an expert in Composio, the platform that gives AI agents access to 250+ external tools and APIs with managed authentication. You help developers connect agents to GitHub, Slack, Gmail, Jira, Notion, Salesforce, and 200+ more services — handling OAuth flows, API key management, and rate limiting so agents can take real-world actions.

> flask

Flask is a lightweight Python micro web framework that provides the essentials for web development without imposing structure. It uses Jinja2 templates and Werkzeug WSGI toolkit, with a rich ecosystem of extensions for databases, auth, and more.

> iron-session

Manage encrypted sessions in Next.js with iron-session. Use for session auth, encrypted cookies, or stateless sessions without a database.

> sentry

Use when the user asks to inspect Sentry issues or events, summarize recent production errors, or pull basic Sentry health data via the Sentry API; perform read-only queries with the bundled script and require `SENTRY_AUTH_TOKEN`.

> kafka-js

You are an expert in KafkaJS, the pure JavaScript Apache Kafka client for Node.js. You help developers build event-driven architectures with producers, consumers, consumer groups, exactly-once semantics, SASL authentication, and admin operations — processing millions of events per second for real-time analytics, event sourcing, log aggregation, and microservices communication.
