Explains web rendering strategies including Client-Side Rendering (CSR), Server-Side Rendering (SSR), Static Site Generation (SSG), Incremental Static Regeneration (ISR), and streaming. Use when deciding rendering strategy, optimizing performance, or understanding when content is generated and sent to users.
Expert frontend development with React, Vue, and modern frameworks including component architecture, state management, performance optimization, and accessibility.
Guidance for implementing high-performance portfolio optimization using Python C extensions. This skill applies when tasks require optimizing financial computations (matrix operations, covariance calculations, portfolio risk metrics) by implementing C extensions for Python. Use when performance speedup requirements exist (e.g., 1.2x or greater) and the task involves numerical computations on large datasets (thousands of assets).
Track and diagnose ClickHouse ALTER UPDATE, ALTER DELETE, and other mutation operations. Use for stuck mutations and mutation performance issues.
Expert guidance for Vite development with modern build tooling, HMR, framework integrations, and performance optimization
Backtest trading strategies on historical data and interpret performance metrics. Provides run_backtest (crypto strategies) and run_prediction_market_backtest (Polymarket strategies). Fast execution (20-60s), minimal cost ($0.001). Returns Sharpe ratio, max drawdown, win rate, profit factor, and trade statistics. Use this skill after building or improving strategies to validate performance before deploying. NEVER deploy without thorough backtesting (6+ months recommended).
Expo React Native JavaScript best practices for clean code, functional components, performance optimization, and Expo Router navigation.
React library for building user interfaces. Use when building web applications, creating components, managing state, handling side effects, or optimizing performance.
Next.js performance optimization and best practices. Use when writing Next.js code (App Router or Pages Router); implementing Server Components, Server Actions, or API routes; optimizing RSC serialization, data fetching, or server-side rendering; reviewing Next.js code for performance issues; fixing authentication in Server Actions; or implementing Suspense boundaries, parallel data fetching, or request deduplication.
Monitor Render services in real-time. Check health, performance metrics, logs, and resource usage. Use when users want to check service status, view metrics, monitor performance, or verify deployments are healthy.
