+**Say one sentence to your agent — Claude Code, Cursor, Codex, OpenClaw, Hermes all work.**
+
+
+
+3 to 30 minutes — you ship a **product launch animation**, a clickable App prototype, an editable PPT deck, a print-grade infographic.
+
+Not "decent for AI" quality — it looks like a real design team made it. Give the skill your brand assets (logo, colors, UI screenshots) and it reads your brand's voice; give it nothing and the built-in 20 design vocabularies still keep you out of AI slop territory.
+
+**Every animation in this README was made by huashu-design itself.** No Figma, no After Effects — just a sentence + skill run. Next product launch needs a promo video? You can make it too.

+> 📖 **Note for English readers**: this skill is built by a Chinese-speaking developer. The skill's agent prompts (`SKILL.md`, `references/*.md`) are in Chinese but the agent is bilingual — works fine with English tasks. The demos below are the English parallel versions; the Chinese ones are in the default-named files (see the Chinese [README.md](README.md)).

+
+## Install
+
+```bash
+npx skills add alchaincyf/huashu-design
+```
+
+Then just talk to Claude Code:
+
+```
+"Make a keynote for AI psychology. Give me 3 style directions to pick from."
+"Build an iOS prototype for a Pomodoro app — 4 screens, actually clickable."
+"Turn this logic into a 60-second animation. Export MP4 and GIF."
+"Run a 5-dimension expert review on this design."
+```
+
+No buttons, no panels, no Figma plugin. Agent-agnostic — drops into Claude Code, Cursor, Trae, Hermes, OpenClaw, or any markdown-skill-capable agent.

+
+### Design Direction Advisor
+
+The fallback for vague briefs: pick 3 differentiated directions from 5 schools × 20 philosophies, generate all 3 demos in parallel, let the user choose.
+
+
+
+### iOS App Prototype
+
+Pixel-accurate iPhone 15 Pro body (Dynamic Island / status bar / Home Indicator) · state-driven multi-screen navigation · real images pulled from Wikimedia/Met/Unsplash · Playwright click tests before delivery.
+
+
+
+### Motion Design Engine
+
+Stage + Sprite time-slice model · `useTime` / `useSprite` / `interpolate` / `Easing` — four APIs cover every animation need · one command exports MP4 / GIF / 60fps-interpolated / BGM-scored finals.
+
+
+
+### HTML Slides → Editable PPTX
+
+HTML decks for browser presentation · `html2pptx.js` reads DOM computed styles and translates each element into real PowerPoint objects · exports are **actual text frames**, not image-bed fakes.
+
+
+
+### Tweaks · Live Variation Switching
+
+Colors / typography / information density parameterized · side panel toggle · pure-frontend + `localStorage` persistence · survives reload.
+
+
+
+### Infographic / Data Viz
+
+Magazine-grade typography · precise CSS Grid columns · `text-wrap: pretty` typographic details · driven by real data · exports to vector PDF / 300dpi PNG / SVG.
+
+
+
+### Junior Designer Workflow
+
+No heroic one-shot attempts: start with assumptions + placeholders + reasoning, show it to the user early, then iterate. Fixing a misunderstanding early is 100× cheaper than fixing it late.
+
+
+
+### Core Asset Protocol · 5-step hard process
+
+Mandatory whenever the task involves a specific brand: ask → search → download (three fallback paths) → verify + extract → write `brand-spec.md` covering **logo, product shots, UI screenshots, colors, fonts** — all required assets, not just colors.
+
+
+
+---
+
+## Core Mechanics
+
+### Core Asset Protocol
+
+The hardest rule in the skill. When the task touches a specific brand (Stripe, Linear, Anthropic, DJI, your own company, etc.), five steps are enforced:
+
+| Step | Action | Purpose |
+|---|---|---|
+| 1 · Ask | Checklist of 6 asset types: logo / product shots / UI screenshots / color palette / fonts / brand guidelines | Respect existing resources |
+| 2 · Search official channels | `.com/brand` · `.com/press` · `brand..com` · product pages · launch films | Find authoritative assets |
+| 3 · Download by asset type | Logo (SVG → inline-SVG in HTML → social avatar) · Product shots (hero → press kit → launch video frames → AI-generated from reference) · UI (App Store screenshots → official video frames) | Three fallback paths per asset type |
+| 4 · Verify + extract | Check logo fidelity · product image resolution · UI freshness · grep color hex from real assets | **Never guess from memory** |
+| 5 · Freeze to spec | Write `brand-spec.md` with logo paths, product image paths, UI screenshot paths, CSS variables for colors/fonts | Un-frozen knowledge evaporates |
+
+**Ranking of asset importance** (from the skill's internal rubric):
+
+1. Logo — mandatory for any brand
+2. Product renders — mandatory for physical products
+3. UI screenshots — mandatory for digital products
+4. Color values — auxiliary
+5. Fonts — auxiliary
+
+A/B-tested (v1 vs v2, 6 agents each): **v2 reduced stability variance by 5×**. Stability of stability — that's the real moat.
+
+### Design Direction Advisor (Fallback)
+
+Triggered when the brief is too vague to execute:
+
+- Don't run on generic intuition — enter Fallback mode
+- Recommend 3 differentiated directions from 5 schools × 20 philosophies, each **from a different school**
+- Each comes with flagship works, gestalt keywords, representative designer
+- Generate 3 visual demos in parallel, let the user choose
+- Once chosen, continue into the Junior Designer main flow
+
+### Junior Designer Workflow
+
+The default working mode across every task:
+
+- Send the full question set in one batch, wait for all answers before moving
+- Write assumptions + placeholders + reasoning comments directly into the HTML
+- Show it to the user early (even if just gray blocks)
+- Fill in real content → variations → Tweaks — show at each of these three steps
+- Manually eyeball the browser with Playwright before delivery
+
+### Fact Verification First (Principle #0)
+
+The highest-priority rule, added after a real failure mode: when the task mentions a specific product / technology / event (e.g., "DJI Pocket 4", "Nano Banana Pro", "Gemini 3 Pro"), the first action **must** be a `WebSearch` to confirm existence, release status, current version, and specs. No claims from training-corpus memory. Cost of a search: ~10 seconds. Cost of a wrong assumption: 1–2 hours of rework.
+
+### Anti AI-slop Rules
+
+Avoid the visual common denominator of AI output (purple gradients / emoji icons / rounded-corner + left border accent / SVG humans / Inter-as-display / **CSS silhouettes standing in for real product shots**). Use `text-wrap: pretty` + CSS Grid + carefully chosen serif display faces + oklch colors.
+
+---
+
+## vs. Claude Design
+
+I'll be upfront: the Core Asset Protocol's philosophy was lifted from system prompts Anthropic wrote for Claude Design. That prompt hammers home a single idea — **great hi-fi design doesn't start from a blank page, it grows from existing design context**. That one principle is the difference between a 65-point design and a 90-point design.
+
+Positioning differences:
+
+| | Claude Design | huashu-design |
+|---|---|---|
+| Form | Web product (used in browser) | Skill (used in Claude Code) |
+| Quota | Subscription quota | API usage · parallel agents unblocked |
+| Output | Canvas + Figma export | HTML / MP4 / GIF / editable PPTX / PDF |
+| Interaction | GUI (click, drag, edit) | Conversation (tell agent, wait) |
+| Complex animation | Limited | Stage + Sprite timeline · 60fps export |
+| Agent compatibility | Claude.ai only | Claude Code / Cursor / Trae / Hermes / OpenClaw |
+
+Claude Design is a **better graphics tool**. Huashu-design makes **the graphics-tool layer disappear**. Two paths, different audiences.
+
+---
+
+## Limitations
+
+- **No layer-editable PPTX-to-Figma round-trip.** The output is HTML — screenshottable, recordable, image-exportable, but not draggable into Keynote for text-position tweaks.
+- **Framer-Motion-tier complex animations are out of scope.** 3D, physics simulation, particle systems exceed the skill's boundaries.
+- **Brand-from-zero design quality drops to 60–65 points.** Drawing hi-fi from nothing was always a last resort.
+
+This is an 80-point skill, not a 100-point product. For people unwilling to open a graphical UI, an 80-point skill beats a 100-point product.

+
+## Origin Story
+
+The day Anthropic launched Claude Design I played with it until 4 a.m. A few days later I realized I hadn't opened it once since — not because it's bad (it's the most polished product in the category) but because I'd rather have an agent work in my terminal than open any graphical UI.
+
+So I had an agent deconstruct Claude Design itself (including the system prompts circulating in the community, the brand asset protocol, the component mechanics), distill it into a structured spec, then write it as a skill installed in my own Claude Code.
+
+Thanks to Anthropic for writing the Claude Design prompts so clearly. This kind of derivative work inspired by other products is the new form of open-source culture in the AI era.
