Configure Litestar stores and the store registry for caching, server-side sessions, rate limiting, and other key-value state with explicit backend selection, bytes-safe data handling, TTL and renewal policy, namespacing, registry wiring, and lifecycle cleanup. Use when a Litestar app depends on `MemoryStore`, `FileStore`, `RedisStore`, `ValkeyStore`, or `StoreRegistry`. Do not use for relational persistence, domain repositories, or response-caching policy details that belong in database or caching-focused skills.
Debug Next.js issues systematically. Use when encountering SSR errors, hydration mismatches like "Text content did not match", routing issues with App Router or Pages Router, build failures, dynamic import problems, API route errors, middleware issues, caching and revalidation problems, or performance bottlenecks. Covers both Pages Router and App Router architectures.
Debug Vue.js 3 application issues systematically. This skill helps diagnose and resolve Vue-specific problems including reactivity failures with ref/reactive, component update issues, Pinia store state management problems, computed property caching bugs, Teleport/Suspense rendering issues, and SSR hydration mismatches. Provides Vue DevTools usage, console debugging techniques, Vite dev server troubleshooting, and vue-tsc type checking guidance.
Master TanStack Query (React Query) v5 for server state management in React applications. Use when fetching data from APIs, managing server state, caching, or handling mutations. Triggers on phrases like "react query", "tanstack query", "data fetching", "cache management", "server state", or file patterns like *query*.ts, *Query*.tsx, queryClient.ts.
When validating system performance under load, identifying bottlenecks through profiling, or optimizing application responsiveness. Covers load testing (k6, Locust), profiling (CPU, memory, I/O), and optimization strategies (caching, query optimization, Core Web Vitals). Use for capacity planning, regression detection, and establishing performance SLOs.
nginx C module performance optimization and reliability guidelines based on the official nginx development guide. This skill should be used when optimizing nginx C modules for throughput, latency, memory efficiency, and operational resilience. Triggers on tasks involving buffer optimization, connection tuning, shared memory contention, error recovery, timeout strategy, caching implementation, worker process tuning, or logging performance in nginx C modules.
Ruby and Rails best practices for services, testing, and architecture. Use when: - Writing or reviewing Ruby/Rails code - Designing service objects or organizing business logic - Setting up RSpec tests with FactoryBot - Building APIs with JSON serialization - Optimizing Rails performance (N+1, caching) Keywords: Ruby, Rails, RSpec, FactoryBot, service object, strong params, N+1 query, Sidekiq, RuboCop, Thor CLI
