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 18 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 440 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 '.

The short version

oh-my-design is an open-source tool with no accounts and no sign-up. We don't sell your data and we don't run ads. This page explains the little we do collect — anonymous analytics, to learn what's useful — in plain language.

Who we are

oh-my-design is maintained by an individual. You can reach us any time at gkffhdnls13@gmail.com.

What we collect & why

We never ask for your name, email, or an account. We collect anonymous usage analytics — which pages and references you view, and actions like select / generate / download / copy — to learn what's useful and improve the tool. We also log JavaScript errors and scroll depth to fix bugs.

We do not collect your IP address in Mixpanel, and we never store it in our own counters.

Cookies & identifiers

Google Analytics sets a cookie (_ga) to count visits. Mixpanel stores a random ID in your browser's local storage. Neither identifies you personally. Our own popularity counters store only an event name and a reference ID — nothing about you.

Who processes the data

We use Google Analytics and Mixpanel for analytics, plus Vercel and Upstash for hosting and counters, and OpenRouterto compute embeddings for the connector's vibe search. We also use Google Search Console to see aggregated, anonymized search performance (no personal data).

These providers operate in the United States, so some anonymous analytics data is processed on servers outside Korea and the EEA. Google LLC self-certifies under the EU–US Data Privacy Framework; transfers to Mixpanel rely on EU Standard Contractual Clauses.

Retired Claude connector (MCP)

The former read-only connector at oh-my-design.kr/api/mcp is retired and returns HTTP 410. It no longer accepts searches, sends phrases to an embedding provider, or records connector usage. Historical aggregate metrics may remain in operational backups under the retention rules above.

Your choices

In the EU, UK, and Switzerland we ask before turning analytics on — you'll see a banner. Choose Decline and no analytics cookies or identifiers are set.

Changed your mind, anywhere? — Decline there turns analytics back off. You can also opt out via your browser's cookie settings or the Google Analytics opt-out add-on.

How long we keep it

Google Analytics keeps event data for up to 14 months. Mixpanel retains analytics data according to its plan's retention policy. Our own counters keep only running totals, with no personal data.

Your rights, children & changes

Email gkffhdnls13@gmail.com to ask about this data or request deletion. EU/UK users have GDPR rights (access, deletion, objection, withdrawing consent); Korean users have rights under PIPA — see the Korean policy. This site isn't directed at children under 14. If anything here changes, we'll update this page and the date at the top.
