Expert-level performance optimization, profiling, benchmarking, and tuning
Master modern GraphQL with federation, performance optimization, and enterprise security. Build scalable schemas, implement advanced caching, and design real-time systems. Use PROACTIVELY for GraphQL architecture or performance optimization.
Master Minecraft server plugin development with Bukkit, Spigot, and Paper APIs. Specializes in event-driven architecture, command systems, world manipulation, player management, and performance optimization. Use PROACTIVELY for plugin architecture, gameplay mechanics, server-side features, or cross-version compatibility.
Performance optimization patterns for Mapbox GL JS web applications. Covers initialization waterfalls, bundle size, rendering performance, memory management, and web optimization. Prioritized by impact on user experience.
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.
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).
Web performance audits with Core Web Vitals, bottleneck identification, optimization recommendations. Use for page load times, performance reviews, UX optimization, or encountering LCP, FID, CLS issues, resource blocking, render delays.
Expert in Python development with best practices across web, data science, and automation
Use when optimizing large value type performance, working with noncopyable types, or reducing ARC traffic. Covers borrowing, consuming, inout modifiers, consume operator, ~Copyable types.
Provides comprehensive guidance for React Hooks including useState, useEffect, useContext, useReducer, useMemo, useCallback, custom hooks, and hook patterns. Use when the user asks about React Hooks, needs to use hooks in functional components, create custom hooks, or optimize hook performance.
Build distinctive, production-grade frontend interfaces. Use when creating any web UI — sites, apps, dashboards, components. Focuses on design quality and avoiding generic AI aesthetics. Composable with other skills (docx, pdf, xlsx).
C# code review skill. Analyzes code quality from OOP, SOLID, GoF design pattern, modern C# features, and performance perspectives. Use before pull requests, when optimizing code, or auditing legacy codebases.
