Open Design Agent Kit

Open Design Agent Kit

English | 简体中文 | 日本語

Pro-grade design, built right into the coding agent you already use.

Open Design Agent Kit brings Open Design's design skills, brand design systems, and remixable examples into GitHub Copilot Chat, Claude Code, Codex, Cursor, and any other MCP-capable agent. Ask for a pitch deck, landing page, dashboard, or mobile prototype in the chat you already have open. Your agent's own model builds it with its own file tools, guided by a library that keeps the result from looking AI-generated.

No desktop app. No daemon. No extra account, API key, or model settings. Install it, ask, and the files show up in your repo.

Why built-in beats another app

Open Design itself is a full local-first desktop app with its own daemon, project database, and model setup. It's excellent, but it's one more thing to install, keep running, configure, and switch into. Most of what makes it valuable day to day isn't the app. It's the content: 181 skills, 114 design templates, 198 brand design systems, 193 remixable example artifacts, and 13 craft docs (typography, color, accessibility, anti-"AI slop"). Agent Kit takes that content and the generation workflow around it and builds them directly into your agent:

What makes it different

- Native to each agent. It isn't a wrapper or a separate UI; each integration uses the agent's own mechanism. In Copilot, that's VS Code languageModelTools, chat instructions, and slash commands. In Claude Code, it's a plugin with skills and a bundled MCP server. In Codex, it's .agents/skills plus MCP. The agent finds the tools on its own, so you just describe what you want.
- A curated library, not a prompt. Task-specific recipes, brand-accurate design tokens, and hard-won craft rules. That's the difference between "a…
