Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/toss/frontend-fundamentals --skill readability- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads readability automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
가독성
코드는 읽기 쉬워야 한다. 읽는 사람이 코드 의도를 빠르게 파악할 수 있어야 한다.
핵심 패턴
동시에 실행되지 않는 코드 분리
❌ viewer/admin 로직이 한 컴포넌트에 섞임:
function SubmitButton() {
const isViewer = useRole() === "viewer";
useEffect(() => {
if (isViewer) return;
showButtonAnimation();
}, [isViewer]);
return isViewer ? (
<TextButton disabled>Submit</TextButton>
) : (
<Button type="submit">Submit</Button>
);
}
✅ 분기별로 분리:
function SubmitButton() {
const isViewer = useRole() === "viewer";
return isViewer ? <ViewerSubmitButton /> : <AdminSubmitButton />;
}
function ViewerSubmitButton() {
return <TextButton disabled>Submit</TextButton>;
}
function AdminSubmitButton() {
useEffect(() => { showButtonAnimation(); }, []);
return <Button type="submit">Submit</Button>;
}
복잡한 조건에 이름 붙이기
❌ 조건이 무슨 뜻인지 바로 안 보임:
if (user.age >= 18 && !user.isBanned && user.emailVerified) { ... }
✅ 의도를 이름으로 표현:
const canPurchase = user.age >= 18 && !user.isBanned && user.emailVerified;
if (canPurchase) { ... }
빠른 참조
| 코드 냄새 | 개선 방법 |
|---|---|
| 중첩된 삼항 연산자 | if문이나 early return 사용 |
복잡한 조건 a && !b || c | 의미있는 이름 붙이기: const canProceed = ... |
| 여러 분기가 교차됨 | 분기별로 별도 컴포넌트 분리 |
| 코드 위아래로 왔다갔다 | 조건을 한눈에 볼 수 있는 객체로 관리 |
주의사항
- 간단한 로직까지 과도하게 추상화하지 말 것
- 나쁜 코드에 주석 대신 코드 자체를 개선
- "미래 유연성" 위해 깊은 계층 만들지 말 것

FAQ
What does the readability skill do?
Use when 삼항 연산자가 중첩되거나, 복잡한 조건식 a && !b c가 이름 없이 사용되거나, 동시에 실행되지 않는 코드가 한 컴포넌트에 섞여 있을 때
How do I install readability?
Run npx skills add https://github.com/toss/frontend-fundamentals --skill readability in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/readability/ (personal) or .claude/skills/readability/ (project).
Which AI agents can use readability?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is readability safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains readability?
