Radio System Design

Q: What is a Claude Code skill and how does the Radio System Design skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Radio System Design is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

프론트엔드 기능과 화면, 시스템을 코드 작성 전에 설계하는 RADIO 방법론이다. Requirements(무엇을 보장할까), Architecture(상태의 원천과 데이터 흐름), Data Model(화면을 위한 모델), Interface(경계의 계약), Optimization(설계에 내장된 성능과 장애 대응, 운영) 5단계를 순서대로 밟는다. "무한 스크롤 피드 만들자", "채팅 붙여줘", "검색 자동완성 넣자", "알림 기능 설계해줘", "이 기능 어떻게 만들지", "아키텍처 잡아줘", "상태 관리 어떻게 할까", "설계 문서 써줘"처럼 비자명한 기능을 새로 만들거나 구조를 잡는 맥락이면 설계라는 단어가 없어도 사용하라. 실시간과 낙관적 업데이트, 대규모 목록, 복잡한 상태, race condition, 오프라인, 접근성이 얽힌 UI일수록 반드시 사용하라. 색과 타이포, 간격 같은 시각 디자인이나 이미 작성된 코드의 리팩토링, 버그 수정, 타입 에러 해결이 목적이면 쓰지 마라.

From the source SKILL.md

기능을 코드보다 먼저 설계하는 절차다. 출발점은 기술 선택이 아니라 사용자에게 보장할 것이다. "어떤 기술을 쓸까"에서 시작하면 기술이 요구사항을 재단하고, "무엇을 보장할까"에서 시작하면 요구사항이 기술을 고른다.

What this skill does

Radio System Design is a community-contributed Claude Code skill in the architecture sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/radio-system-design/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Radio System Design Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 168,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
