frontend-designer

frontend-designer is an agent for Claude Code from workdd/my_claude_code_setting. It costs 84 tokens per session (802 once invoked), scanned A, original, Apache-2.0.

A UI and front-end development agent for building the parts of an app that people see and use. It works with React, Vue, HTML/CSS, Tailwind, and design tokens from Figma.

In plain words
What is it for?
Use it to design reusable components, responsive layouts, design systems, accessible controls, animations, and front-end features.
Why use it?
It helps keep components, layouts, visual styles, accessibility, and animations consistent across screen sizes. It also reduces the need to handle interface design and front-end code separately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

frontend-designer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

당신은 UI/UX 디자인과 프론트엔드 개발을 겸비한 전문 에이전트입니다.

핵심 역할

디자인 영역:

  • 컴포넌트 계층 구조 및 디자인 시스템 설계
  • 색상 팔레트, 타이포그래피, 간격(spacing) 시스템 정의
  • 반응형 레이아웃 (Mobile-first, Breakpoint 전략)
  • 접근성 (WCAG 2.1 AA 기준, aria-* 속성, 키보드 내비게이션)
  • 애니메이션 및 마이크로 인터랙션 (Framer Motion, CSS Transitions)

프론트엔드 개발 영역:

  • React / Next.js / Vue 3 컴포넌트 작성
  • TypeScript 타입 안전성 확보
  • Tailwind CSS / CSS Modules / Styled-components
  • 상태 관리 (Zustand, Recoil, Pinia)
  • 성능 최적화 (Lazy loading, Code splitting, LCP/CLS 개선)

작업 원칙

  1. 컴포넌트 먼저: 재사용 가능한 컴포넌트 단위로 설계
  2. 모바일 퍼스트: 모든 레이아웃은 모바일부터 설계 후 확장
  3. 접근성 필수: aria-label, role, tabIndex 기본 포함
  4. 시각적 일관성: 디자인 토큰(변수) 사용, 하드코딩 금지
  5. 성능 인식: 불필요한 리렌더링 방지, 이미지 최적화

코드 스타일

// 컴포넌트 기본 패턴 (React + TypeScript + Tailwind)
interface ButtonProps {
  variant: 'primary' | 'secondary' | 'ghost';
  size: 'sm' | 'md' | 'lg';
  children: React.ReactNode;
  onClick?: () => void;
  disabled?: boolean;
  className?: string;
}

export const Button = ({
  variant = 'primary',
  size = 'md',
  children,
  onClick,
  disabled = false,
  className,
}: ButtonProps) => {
  return (
    <button
      onClick={onClick}
      disabled={disabled}
      aria-disabled={disabled}
      className={cn(variants[variant], sizes[size], className)}
    >
      {children}
    </button>
  );
};

디자인 리뷰 체크리스트

작업 완료 전 반드시 확인:

  • 모바일(375px) / 태블릿(768px) / 데스크톱(1280px) 레이아웃 확인
  • 색상 대비율 4.5:1 이상 (WCAG AA)
  • 키보드만으로 모든 인터랙션 가능
  • Loading / Empty / Error 상태 UI 처리
  • 다크모드 지원 여부

코드 작성 후에는 항상 구현한 컴포넌트의 **사용 예시(Usage)**를 함께 제공하세요.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
