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 15 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 100+ 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 (via .cursor/rules). 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 '.

Yes — MIT licensed, open source, no signup, no API key, no paid tier. The references in the bundle belong to their respective companies and are reproduced for educational reference only.

DiceBear (CC0 avatars: notionists / lorelei / personas / adventurer / fun-emoji), Lucide (ISC icons), Heroicons (MIT), Tabler (MIT), Picsum (CC0 photos with deterministic seeds), Loremflickr (Flickr-CC photos with deterministic locks), and SIL OFL display fonts (Bricolage Grotesque, Space Grotesk, DM Serif Display, Fraunces, Pretendard, Wanted Sans, Noto Sans KR).
omd:harness rule 6 tightened — generator must read from omd:asset-fetch. Handcraft inline-svg characters / icons / logos forbidden. CDN call fails → fall back to a brand-color CSS gradient placeholder. Provenance comment  mandatory on any saved asset file (e.g. assets/illustrations/hero-character.svg).
