DESIGN.md is a structured markdown file that defines your project's brand spec — tokens (colors, typography, spacing, radius), voice, narrative, principles, personas, states, and motion. AI coding agents (Claude Code, Codex, OpenCode, Cursor) read it as authoritative context before generating any UI, so the output looks like your brand instead of generic 'modern minimalist' slop.

How does oh-my-design work?

Run `npx oh-my-design-cli install-skills` once in your project. It installs 17 skills (core flow + live-capture + asset + the v0.2 agent layer: orchestrator, kr-writer, locale-adapter, designer-review, final-qa, codex-image), 16 sub-agents (master orchestrator + 15 specialists), 4 hooks, and 221 reference DESIGN.md files. After restarting your AI coding agent, you just talk in natural language — skills route to the right sub-agents automatically.

Does it call any AI provider during install?

No. The install is a pure markdown copy — zero API calls, zero data leaves your machine. Your AI coding agent (Claude Code, Codex, OpenCode, or Cursor) is the inference layer; install just teaches it where to look.

Which AI coding agents are supported?

Claude Code, Codex, OpenCode, and Cursor — Cursor has a dedicated install channel (--agent cursor) that writes the .cursor/rules shim plus the shared reference catalog. The skill markdown files are agent-agnostic; hooks ship for Claude Code specifically.

What is the design harness?

The omd-harness skill runs a 10-phase design pipeline (Discovery → Research → IA → Wireframes → Design system → Components → Asset sourcing → Microcopy → Validation → Handoff). It dispatches sub-agents in parallel where independent, asks 3 mandatory user checkpoints, and emits a v0/Cursor-ready package. Trigger it by saying things like 'design the entire onboarding from scratch' or '/omd-harness '.

TW 5 — Accupass · FunNow · Firstory · Omnichat · Greenvines(綠藤生機).
US 5 — Google(Material 3) · Microsoft(Fluent 2) · Adobe(Spectrum 2) · Salesforce(SLDS 2 styling hooks) · Dropbox(brand.dropbox.com). 공식 DS 헤비웨이트 5종이 처음으로 카탈로그에 합류.
전 레퍼런스 Proof Gate(라이브 inspect raw sample ≥5) + token↔prose 정합 게이트 통과, KR/TW는 brand-owned Tier-1 소스 ≥2 충족.
KR 5 (2차) — Ringle(링글) · POSTYPE(포스타입) · LaundryGo(런드리고) · Greeting(그리팅) · Danawa(다나와). 개선된 게이트 파이프라인으로 추가 — 5/5 첫 실행에 전 게이트 그린.
새 파이프라인 스크립트 — web/scripts/verify-reference.mjs(레퍼런스 단독 게이트: catalog-integrity per-ref 항목 + strict-YAML + 로고 liveness, registry 빌드 불필요) + web/scripts/sync-catalog.mjs(fingerprints ×3 / design-md mirror / 카운트 문자열 / llms.txt Examples / npm test 일괄). omd:add-reference 스킬에 batch 서브에이전트 프로토콜 명문화.
