Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
Use when building an LLM-powered app that needs cost control via model routing, budget tracking, retry, and prompt caching.
Product Detail Page architecture, image gallery/carousel, caching, and add-to-cart flow. Use when modifying PDP layout, debugging gallery swipe/thumbnails, understanding LCP optimization, fixing ErrorBoundary issues, or working with variant-specific images.
Optimize application performance and scalability. Use when investigating slow applications, scaling bottlenecks, or improving response times. Use for profiling, caching, database optimization, frontend performance, and backend tuning.
Implement custom caching with CacheMgr in B2C Commerce. Use when adding application-level caching, cache invalidation, or optimizing performance with custom cache regions. Covers cache definition JSON, CacheMgr API, and cache entry lifecycle.
Use this skill when setting up or managing monorepos, configuring workspace dependencies, optimizing build caching, or choosing between monorepo tools. Triggers on Turborepo, Nx, Bazel, pnpm workspaces, npm workspaces, yarn workspaces, build pipelines, task orchestration, affected commands, and any task requiring multi-package repository management.
Configure Redis for caching and data storage. Set up clustering, persistence, and Sentinel. Use when implementing Redis caching or queues.
Guide for using MSBuild Server to improve CLI build performance. Only activate in MSBuild/.NET build context. Activate when developers report slow incremental builds from the command line, or when CLI builds are noticeably slower than IDE builds. Covers MSBUILDUSESERVER=1 environment variable for persistent server-based caching. Do not activate for IDE-based builds (Visual Studio already uses a long-lived process).
Creates comprehensive GitHub Actions CI/CD workflows for linting, testing, building, and deploying. Includes caching strategies, matrix builds, artifact handling, and failure diagnostics. Use for "GitHub Actions", "CI pipeline", "workflow automation", or "continuous integration".
Cloudflare Workers, Deno Deploy, Vercel Edge Functions, edge patterns (geo-routing, caching). Use when implementing edge compute, CDN logic, or global low-latency APIs.
Optimize website and web application performance including loading speed, Core Web Vitals, bundle size, caching strategies, and runtime performance
Optimize API response times through caching, compression, and efficient payloads. Improve backend performance and reduce network traffic.
