baoyu-design

Run Claude Design on your own local agent — Cursor, Claude Code, Claude Desktop, or any file‑capable coding agent.

English · 简体中文 · Changelog

baoyu-design packages Claude Design — the design engine behind claude.ai/design — as a portable Agent Skill. Drop it into a local agent and you get most of what the website does, right inside your editor: polished UI mockups, interactive prototypes, wireframes, landing pages, dashboards, mobile apps, and slide decks — all produced as self‑contained HTML.

No website, no separate subscription, no upload step. The agent already on your machine does the work, and every artifact stays in your repo.

Screenshots

The same Reader Mac App prompt was used in Cursor, Codex, Claude, and Claude Design.

Why run it locally

• Free yourself from the website. You get the vast majority of claude.ai/design's capabilities without ever leaving your editor — same methodology, same craft standards, same output format.
• Best with Opus 4.8. The skill is a long, demanding design brief; the stronger the model, the better the result. Pair it with Claude Opus 4.8 for the best output, and it still works well on other capable models.
• Iterate by pointing, not describing. Because the deliverable is plain HTML served on localhost, you can lean on your agent's built‑in browser preview and element‑annotation tools (Cursor Browser / DevTools, Claude Preview, or Codex Browser). Point at a button in the live preview, say what you want changed, and the agent edits the underlying source — a tight, visual second‑pass editing loop that's hard to get on a website.
• Everything is yours. Output lands in designs/<project>/ as self‑contained HTML you can version, fork, export, or ship.

What it can make

The skill drives a full design process — clarifying questions → gathering design context → producing one or more HTML deliverables → previewing and verifying. It ships a deep bench of built‑in skills and a set of ready‑made component scaffolds.

Starter components (in starter-components/) save the agent from hand‑rolling the basics: iOS / Android / macOS / browser frames, a pan‑zoom design canvas, a slide‑deck stage, a timeline animation engine, a tweaks panel, and a fillable image slot.

How it works

The skill is plain Markdown plus a few JSX/JS scaffolds — no build step, no runtime.

When you ask for a design, the agent reads SKILL.md, loads the core methodology from system-prompt.md, detects whether it's running in Cursor, Claude Code, Codex Agent, or a generic file‑capable harness, and reads the matching reference doc when one exists. It then pulls in only the built‑in skill(s) the task needs. The split keeps craft rules harness‑independent while each environment resolves its own tools for asking questions, previewing, screenshotting, and verifying.

Quick start

Prerequisites

• A local agent — Cursor, Claude Code, Codex, or any of the 70+ agents the installer supports (Cline, Roo Code, GitHub Copilot…). Cursor, Claude Code, and Codex have first‑class tool references inside the skill.
• Claude Opus 4.8 selected as the model, for best results.
• Node.js (to run the npx installer below). Python 3 is also handy for the local preview server.

Install

Recommended — the skills CLI. npx skills (from Vercel Labs) reads this repo, finds skills/baoyu-design/, and drops it into the right folder for whatever agent it detects:

# Install into the current project (auto‑detects your agent)
npx skills add JimLiu/baoyu-design

# …or install globally, for every project
npx skills add JimLiu/baoyu-design -g

# Target a specific agent explicitly
npx skills add JimLiu/baoyu-design --agent claude-code
npx skills add JimLiu/baoyu-design --agent cursor
npx skills add JimLiu/baoyu-design --agent codex

# Just list what's in the repo first
npx skills add JimLiu/baoyu-design --list

It installs to .claude/skills/ for Claude Code and .agents/skills/ for Cursor/Codex-style agents (add -g for the ~/‑level user install).

Update

If you installed baoyu-design with the skills CLI, update it from the terminal:

# Update and let the CLI prompt for the install scope
npx skills update baoyu-design

# Update the project-level install
npx skills update baoyu-design -p -y

# Update the global install
npx skills update baoyu-design -g -y

upgrade is also supported as an alias:

npx skills upgrade baoyu-design

You can also run npx skills update to update all installed skills. After updating, restart Claude Code (or start a new agent session) so the refreshed skill files are loaded.

Alternative — hand the repo URL to your agent. Don't want to install anything? Paste the URL into chat and let the agent fetch the skill itself:

Read https://github.com/JimLiu/baoyu-design and follow its skills/baoyu-design/SKILL.md to design a settings screen for a meditation app.

The agent clones or fetches the repo, loads SKILL.md, and proceeds — perfect for a one‑off.

Use it

Once the skill is installed (or fetched), just describe a design task in plain language — it auto‑activates from its description:

Design 3 hi‑fi variations of a settings screen for a meditation app.

In Claude Code you can also trigger it explicitly with /baoyu-design; in Codex, mention $baoyu-design when skills are available. The agent asks a few clarifying questions, builds the HTML under designs/, and previews it over localhost. Point at any element in the live preview and say what to change — the agent edits the underlying source for a fast, visual second pass.

Preview server

Deliverables are previewed over HTTP (multi‑file prototypes won't load from file://). The agent normally starts this for you; to run it by hand:

python3 -m http.server 4311 --directory designs
# then open http://localhost:4311/<project>/<file>.html

Design systems

Beyond one‑off mockups, the skill can hold a whole project to a design system — a versioned bundle of a brand's tokens, fonts, components, and full UI kits. Systems live next to your projects under designs/: author one with the Create design system built‑in skill, drop in a pre‑built one, or import one from a Figma .fig file (see the next section). Once a system exists, two flows let any project consume it.
