Schema-first validation with Zod, timing patterns (reward early, punish late), async validation, and error message design. Use when implementing form validation for any framework. The foundation skill that all framework-specific skills depend on.
Refactor Express.js/Node.js code to improve maintainability, readability, and adherence to best practices. Transforms callback hell, fat route handlers, and outdated patterns into clean, modern JavaScript/TypeScript code. Applies async/await, controller-service-repository architecture, proper middleware patterns, and ESM modules. Identifies and fixes anti-patterns including blocking event loop, improper error handling, forEach with async callbacks, and memory leaks.
Refactor NestJS/TypeScript code to improve maintainability, readability, and adherence to best practices. Identifies and fixes circular dependencies, god object services, fat controllers with business logic, deep nesting, and SRP violations. Applies NestJS patterns including proper module organization, provider scopes, custom decorators, guards, interceptors, pipes, DTOs with class-validator, exception filters, CQRS, repository pattern, and event-driven architecture. Transforms code into exemplary implementations following SOLID principles.
Add a new tool to an existing FastMCP server with guided configuration
Generate or update infographic Structure components for this repo (TypeScript/TSX in src/designs/structures). Use when asked to design, implement, or modify structure layouts (list/compare/sequence/hierarchy/relation/geo/chart), including layout logic, component composition, and registration.
React/TypeScript 코드 리팩토링을 위한 비판적 분석 및 실행 스킬. 사용자가 컴포넌트 경로와 문제점을 제시하면, 각 문제점을 "수정하기 좋은 코드" 관점에서 비판적으로 검토하고, sequential-thinking으로 단계별 분석 후 리팩토링 계획을 수립하여 실행한다. 트리거: "리팩토링", "개선하고 싶어", "코드 구조 변경", "훅 분리", "응집도", "결합도" 등의 키워드와 함께 React 컴포넌트 경로가 제시될 때 사용.
Hexagonal grid mathematics, coordinate systems, pathfinding, and spatial algorithms for hex-based games. Use when implementing hex grids, calculating hex distances, finding neighbors, pathfinding on hex maps, spreading effects across hexes, or converting between coordinate systems. Triggers on requests involving hexagonal grids, hex coordinates, A* on hex maps, or hex-based game mechanics.
Explain how to do logging
Audit and refactor code for clarity, maintainability, and correctness. Use when the user asks to refactor, clean up code, reduce complexity, fix code smells, or improve code quality.

Next Friday code style rules for formatting, structure, and readability. Use when writing functions, conditionals, or organizing code.
Apply factory function patterns to compose clients and services with proper separation of concerns. Use when creating functions that depend on external clients, wrapping resources with domain-specific methods, or refactoring code that mixes client/service/method options together.
