bootstrap-design

bootstrap-design is a skill for Claude Code, Codex from kohj1018/agentic-dev-harness. It costs 50 tokens per session (9,247 once invoked), scanned A, original, MIT.

A guided process for choosing a user interface’s visual direction and recording the decisions in DESIGN.md.

In plain words
What is it for?
Use it for projects with a user interface when selecting design concepts, defining visual rules, and documenting accessibility, motion, responsive behavior, and states.
Why use it?
It helps teams make visual choices deliberately before building the interface, using reference research and reviewed concepts.

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

bootstrap-design 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 4d 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.

The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/bootstrap-design

모드: How-to (UI 시각 결정 라운드) 패턴: discover-product 차용 — context: fork를 명시하지 않아 메인 세션이 R0~R6를 직접 운전한다. R0 방향 리서치·값 grounding은 Agent 도구로 researcher(디자인 레퍼런스 모드) + 분해·시안 authoring은 designer 단발 sub-call 위임(ADR-058). 종료 후 사용자가 /clear 권장. 라운드 구조·R0 리서치·수용 게이트·시안 카드 SSOT는 ADR-058(design workflow). DESIGN.md 내용(8섹션+Motion / 3-tier 토큰 / Don'ts / 정체성·a11y·category state·responsive)·인터페이스 할당 SSOT는 ADR-027.

트리거

  • /bootstrap-stack 종료 출력에 "frontend 감지됨. /bootstrap-design 권장" 텍스트 한 줄. 사용자 발화로 시작.
  • 비-UI 프로젝트(API server·CLI 등)는 호출되지 않음 — UI surface 가 없어 design 산출물이 불필요하기 때문이며 ADR-031 직접 지원 범위와는 무관하다(API server·CLI 도 직접 지원 6종에 포함 — ADR-031#amend-1).
  • 본 skill은 baseline placeholder DESIGN.md를 채우는 흐름. 비-UI 프로젝트는 fork 직후 DESIGN.md를 삭제했음을 전제. 파일 부재 시 작업 중단 + 사용자에게 보고.

Codex: 본 skill은 wrapper 미보유(자연어 호출) — Codex에서는 "Follow .claude/skills/bootstrap-design/SKILL.md"로 호출한다(목록 SSOT = README, ADR-010#amend-3·#amend-4). 본문의 Agent 위임(R0 researcher 디자인 레퍼런스 조사 · R0~R2 designer authoring · R2-1.5 reviewer 구별성 비평 · R2-G/R6 reviewer 픽셀 판정 · 게이트 repair designer 재생성)은 Codex에 persona 매핑이 없어 메인 세션이 각 persona 파일(researcher.md/designer.md/reviewer.md)을 읽고 순차 인라인 수행하며 생략하지 않는다(ADR-010). 동일 세션 degrade 계약 (ADR-058 D5): (a) designer→reviewer 페르소나 전환을 명시적 단계로 끊고, (b) 그 라운드 산출물과 최종 출력에 under-verified: 동일 세션 감사를 명시하며, (c) 완전 독립 감사가 요구되면 승인 보류한다. 결정적 렌더 게이트(STACK_SETUP_PLAN.md ## Design Gate Adapter의 current-ready v2 command)는 세션 격리와 무관하게 그대로 실행되므로 배포불가 결함(serious/critical axe·320 geometry)은 Codex 경로에서도 차단된다.

모드

  • --fast: R0(Layer A/B minimal — 있으면 사용자 힌트 우선, 없으면 자율 조사 1~2개로 최소 grounding + minimal 노트) + R1(원칙 1줄 + voice 기본값 확인 1회) + R3(토큰) + R5(저장 — 축약 섹션, §10 포함). R2(concept 시안)·R4(컴포넌트 인벤토리)·R6(preview)는 생략 — R5 저장은 생략하지 않는다. R1은 완전 생략 금지(minimal 1줄). 게이트는 산출물 기준 — --fast는 R2·R6(concept/preview) 미생성이라 게이트 적용 대상 없음(N/A, ADR-058 D3). --fast에서 concept·preview가 필요하면 종료 후 명시 발화로 R2/R6 단독 수행.
  • 기본: R0~R6 모두.
  • --update: 기존 DESIGN.md가 있을 때의 부분 갱신/재디자인 모드(아래 ## --update 모드). 처음부터 R0~R6를 다시 돌지 않는다.

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.
