TypeScript code style and optimization guidelines. Use when writing TypeScript code (.ts, .tsx, .mts files), reviewing code quality, or implementing type-safe patterns. Triggers on TypeScript development, type safety questions, or code style discussions.
Master Rust async programming with Tokio, async traits, error handling, and concurrent patterns. Use when building async Rust applications, implementing concurrent systems, or debugging async code.
React 성능 최적화 및 베스트 프랙티스 스킬. Vercel Engineering 가이드 기반, 프레임워크 비종속. 다음 상황에서 사용: (1) React 컴포넌트(.tsx, .jsx) 작성 또는 수정 시, (2) 상태 관리, hooks, 리렌더링 최적화 작업 시, (3) 비동기 데이터 페칭 또는 Suspense 패턴 작업 시, (4) 번들 사이즈 최적화 또는 코드 스플리팅 시, (5) 'react', 'useState', 'useEffect', 'useMemo', 'useCallback', 'memo', 'Suspense', 'lazy' 키워드가 포함된 작업 시
Reviews LangGraph code for bugs, anti-patterns, and improvements. Use when reviewing code that uses StateGraph, nodes, edges, checkpointing, or other LangGraph features. Catches common mistakes in state management, graph structure, and async patterns.
This skill should be used when the user asks to "optimize TypeScript performance", "speed up tsc compilation", "configure tsconfig.json", "fix type errors", "improve async patterns", or encounters TS errors (TS2322, TS2339, "is not assignable to"). Also triggers on .ts, .tsx, .d.ts file work involving type definitions, module organization, or memory management. Does NOT cover TypeScript basics, framework-specific patterns, or testing.
Advanced JavaScript patterns, ES2024+, and runtime optimization
React and Next.js performance patterns. Use when writing, reviewing, or optimizing React components.
FastAPI best practices, async patterns, and Pydantic validation
Node.js development principles and decision-making. Framework selection, async patterns, security, and architecture. Teaches thinking, not copying.
Reviews Python code for type safety, async patterns, error handling, and common mistakes. Use when reviewing .py files, checking type hints, async/await usage, or exception handling.
Current TypeScript guidance, including TypeScript 7 migration, tsconfig design, type errors, declaration performance, async patterns, module organization, and runtime type safety. Use for .ts, .tsx, and .d.ts work; framework-specific patterns and testing are covered by their dedicated skills.
Advanced concurrency patterns for Tokio including fan-out/fan-in, pipeline processing, rate limiting, and coordinated shutdown. Use when building high-concurrency async systems.
