Three.js 3D building system with spatial indexing, structural physics, and multiplayer networking. Use when creating survival games, sandbox builders, or any game with player-constructed structures. Covers performance optimization (spatial hash grids, octrees, chunk loading), structural validation (arcade/heuristic/realistic physics modes), and multiplayer sync (delta compression, client prediction, conflict resolution).
Decision framework for React Three Fiber projects. Routes to specialized R3F skills (fundamentals, geometry, materials, performance, drei) based on task requirements. Use when starting an R3F project or needing guidance on which R3F skills to combine.
Client-side React performance optimization patterns.
Principal backend engineering intelligence for C++ systems and performance-critical services. Actions: plan, design, build, implement, review, fix, optimize, refactor, debug, secure, scale backend code and architectures. Focus: correctness, memory safety, latency, reliability, observability, scalability, operability.
Principal backend engineering intelligence for Java services and distributed systems. Actions: plan, design, build, implement, review, fix, optimize, refactor, debug, secure, scale backend code and architectures. Focus: correctness, reliability, performance, security, observability, scalability, operability, cost.
Principal backend engineering intelligence for Node.js runtime systems. Actions: plan, design, build, implement, review, fix, optimize, refactor, debug, secure, scale backend code and architectures.

Complete guide for Rust systems programming including ownership, borrowing, concurrency, async programming, unsafe code, and performance optimization
Optimize Inertia Rails application performance. Use when implementing code splitting, prefetching, deferred props, infinite scrolling, polling, or other performance optimizations.
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).
Optimize web performance: Core Web Vitals (LCP, CLS, INP), bundle size, images, caching. Use when site is slow, optimizing for Lighthouse scores, reducing bundle size, fixing layout shifts, or improving Time to Interactive. Triggers on: web performance, Core Web Vitals, LCP, CLS, INP, FID, bundle size, page speed, slow site.
Expert in the Swift ecosystem, specializing in iOS/macOS/visionOS development, Swift 6 concurrency, and deep system integration.
Use when implementing gesture composition (simultaneous, sequenced, exclusive), adaptive layouts (ViewThatFits, AnyLayout, size classes), or choosing architecture patterns (MVVM vs TCA vs vanilla, State-as-Bridge). Covers advanced SwiftUI patterns beyond basic views.
