CCXT cryptocurrency exchange library for Python 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 Python. Use when working with crypto exchanges in Python projects, trading bots, data analysis, or portfolio management. Supports both sync and async (asyncio) usage.
Implement and maintain the OKX broker/provider integration for this workspace using okx-api SDK best practices, including auth/signing, spot/margin/futures/options trading, market/account endpoints, rate limiting, websocket subscriptions, and OKX error handling. Use when adding or changing any code under src/providers/okx or when an LLM needs canonical SDK usage patterns derived from .trae/okx-api-llm.txt.
Set up real-time indicator computation on live WebSocket market data. Streams LTP/Quote/Depth and computes indicators in real-time with optional Plotly live charting.
Read market data for a known Kalshi prediction market on DFlow — orderbook, trades, top-of-book prices, candlesticks, forecast-percentile history, and Kalshi in-game live data — via one-shot REST snapshots, historical ranges, or live WebSocket streams. Use when the user asks "show me the orderbook for X", "get last hour of trades", "build a live price ticker", "stream orderbook depth", "pull 1-minute candles for the last day", "watch in-game scores for this sports market", or "alert me when the orderbook moves". Do NOT use to discover markets matching a criterion (use `dflow-kalshi-market-scanner`), to place orders (use `dflow-kalshi-trading`), or to read a user's own positions/P&L (use `dflow-kalshi-portfolio`).
Build a realtime chat room backend with Rivet Actors: one actor per room, SQLite-backed message history, and WebSocket broadcast to every connected client.
Generate a production-grade React MQTT context for CloudSignal real-time notifications over WebSocket. Supports Clerk, Supabase, Auth0, Firebase, and custom OIDC auth providers. Use when implementing real-time notifications, live updates, job progress tracking, or WebSocket messaging with CloudSignal.
Centrifugo real-time messaging server expert for WebSocket PUB/SUB, channel management, JWT authentication, event proxying, and horizontal scaling with Redis/NATS. Use when: centrifugo, centrifugal, real-time messaging, websocket pubsub, channel subscriptions, real-time notifications, live updates, presence, history recovery, server-sent events integration, real-time transport layer. Do not use for: general WebSocket programming without Centrifugo, Socket.IO, Pusher SDK, or other real-time frameworks.
Production-grade WebSocket connection management with connection limits, user-to-connection mapping, ping/pong health verification, and automatic stale connection cleanup.
Best practices and guidelines for building real-time applications with WebSocket communication
Build and send Feishu interactive message cards (buttons, selects, status indicators). Handles card callback events from WebSocket. Use when sending morning briefings, alerts, confirmations, or any message that benefits from user interaction via buttons instead of text replies.
A Python CLI for interacting directly with the user's running Chromium browser via the Chrome DevTools Protocol (CDP). Connects via WebSocket to inspect pages, extract data, evaluate JS, and automate UI actions in open tabs. Requires explicit user approval; a background daemon ensures the "Allow debugging" prompt only requires one approval per tab.
Chrome/Edge extension for debugging WebSocket connections with message simulation, traffic blocking, and real-time monitoring
