Live cursors and multiplayer presence with Rivet Actors: per-connection cursor state, realtime updates over events or raw WebSockets, and throttling.
Implement real-time bidirectional communication with WebSockets including connection management, message routing, and scaling. Use when building real-time features, chat systems, live notifications, or collaborative applications.
Setup and use ActionCable for real-time features in Rails applications using WebSockets. Use when implementing real-time updates, live notifications, broadcasting changes, or when the user mentions WebSockets, ActionCable, channels, broadcasting, or Turbo Streams over cable.
Azure AI Voice Live SDK for .NET. Build real-time voice AI applications with bidirectional WebSocket communication. Use for voice assistants, conversational AI, real-time speech-to-speech, and voice-enabled chatbots. Triggers: "voice live", "real-time voice", "VoiceLiveClient", "VoiceLiveSession", "voice assistant .NET", "bidirectional audio", "speech-to-speech".
Build Model Context Protocol (MCP) servers on Cloudflare Workers - the only platform with official remote MCP support. TypeScript-based with OAuth, Durable Objects, and WebSocket hibernation. Use when: deploying remote MCP servers, implementing OAuth (GitHub/Google), using dual transports (SSE/HTTP), or troubleshooting URL path mismatches, McpAgent exports, OAuth redirects, CORS issues.
Builds AI agents on Cloudflare using the Agents SDK with state management, real-time WebSockets, scheduled tasks, tool integration, and chat capabilities. Generates production-ready agent code deployed to Workers. Use when: user wants to "build an agent", "AI agent", "chat agent", "stateful agent", mentions "Agents SDK", needs "real-time AI", "WebSocket AI", or asks about agent "state management", "scheduled tasks", or "tool calling".
Expert guidance on real-time communication patterns including WebSockets, Server-Sent Events (SSE), Socket.IO, and WebRTC. Covers connection management, reconnection strategies, scaling, and real-time data synchronization. Use when "implement websocket, real-time updates, live chat, socket.io, server-sent events, live notifications, collaborative editing, presence indicators, Working with ws, Socket.IO, Pusher, Ably, websocket, realtime, socket.io, sse, live, streaming, push, collaboration" mentioned.
CCXT cryptocurrency exchange library for PHP developers. Covers both REST API (standard) and WebSocket API (real-time). Helps install CCXT, connect to exchanges, fetch market data, place orders, stream live tickers/orderbooks, handle authentication, and manage errors in PHP 8.1+. Use when working with crypto exchanges in PHP projects, trading bots, or web applications. Supports both sync and async (ReactPHP) usage.
Builds reactive real-time backends on the iii engine. Use when building event-driven apps where state changes automatically trigger side effects, clients receive live updates via streams or websockets, or you need a real-time database layer with pub/sub and CRUD endpoints.
FastAPI framework mechanics and advanced patterns. Use when configuring middleware, creating dependency injection chains, implementing WebSocket endpoints, customizing OpenAPI documentation, setting up CORS, building authentication dependencies (JWT validation, role-based access), implementing background tasks, or managing application lifespan (startup/shutdown). Does NOT cover basic endpoint CRUD or repository/service patterns (use python-backend-expert) or testing (use pytest-patterns).
Manifold is a prediction market platform where users trade on the outcomes of real-world events using play-money (mana) and prize-cash. Use this skill to interact with the Manifold API for market discovery, trading, market creation, portfolio management, WebSocket streaming, and comments.
Tests WebSocket API implementations for security vulnerabilities including missing authentication on WebSocket upgrade, Cross-Site WebSocket Hijacking (CSWSH), injection attacks through WebSocket messages, insufficient input validation, denial-of-service via message flooding, and information leakage through WebSocket frames. The tester intercepts WebSocket handshakes and messages using Burp Suite, crafts malicious payloads, and tests for authorization bypass on WebSocket channels. Activates for requests involving WebSocket security testing, WS penetration testing, CSWSH attack, or real-time API security assessment.
