# Web Clone

> Clones websites: find the real source first or run browser recon, pick a path for static, React/Vue/Next or WebGL/Canvas/Three.js sites, strip trackers, check licenses, and verify against the original before swapping in your content. In Chinese; script paths assume the author's machine.

# 🪞 Web Clone · 网站复刻方法论

> Reproduce any website — from a single-file static page to a WebGL-heavy interactive demo — without faking it from AI hallucinations.
> 把任何一个网站(从单文件静态页到 WebGL 重前端 demo)忠实复刻出来 —— 不靠 AI 臆测代码硬抄。

## What this skill does

You see a website you love. You want to clone it — to learn how it works, to remix it into your own thing, or to run it offline. AI tools love to produce *plausible-looking* "clone analysis" documents full of code blocks that are entirely fabricated and break the moment you run them.

This skill is a **methodology plus executable probes that put real source first**, with a 6-step decision tree covering:

- Static HTML/CSS sites → `wget --mirror`
- React / Vue / Next content sites → rebuild on a template
- Multi-page sites → crawl internal routes before designing templates
- Interactive sites → record hover / click / scroll / canvas-drag states before cloning
- **WebGL / Canvas / Three.js heavy frontends** → reverse-engineer real source, line by line; when there's no findable source, runtime frame-capture + a **baseline-first replay gate** with `SOURCE / PARTIAL / GUESS` evidence grading
- **Static-built sites (Astro / Vite SSG / Hugo), even WebGL-heavy** → `mirror-site.mjs` full-scroll-captures and mirrors every deployed asset (incl. runtime-fetched `.sog/.buf/.wasm`) for a true 1:1 clone — for a static site, "get the real source" = "mirror the whole deployed bundle"
- Verify in a real browser, document the truth, replace content with yours
- **Visual / rebrand modes** → distill a versionable `design-dna.json` (design tokens + style + effects), then "keep the DNA, swap the content"

## Iron rule: real source first, never copy AI-guessed code

> Any AI-written "clone analysis" — treat the conceptual skeleton as a hint, but **assume every executable code block is hallucinated** until you've verified it against real source code line by line.

**Case in point** (see `references/marbles-case.md`): A real WebGL marbles demo uses **analytic ray-sphere intersection** + an SVG `feDisplacementMap` to refract the live DOM. An AI analysis confidently described it as **ray-marching + SDF + sampling the DOM as a texture** — two entirely different implementations. Copying the AI version produces nothing like the original and runs many times slower.

So **step 1 is always: get the real source**.

## Install

This is a [Claude Code skill](https://docs.claude.com/en/docs/agents-and-tools/skills). Drop it into your skills directory:

```bash
git clone https://github.com/Jane-xiaoer/claude-skill-web-clone.git ~/.claude/skills/web-clone
```

Then use it by saying things like:
- "复刻这个网站: https://..."
- "Clone this site for me"
- "Reverse-engineer this WebGL demo"
- "把这个站抄下来改成我的"

Claude / Codex will load `SKILL.md` and walk the decision tree.

## The decision tree (one-screen summary)

| Step | What to do |
|---|---|
| **1** | `gh api search/repositories?q=<name>` — find the real source on GitHub FIRST |
| **2** | If no source: browser-probe the site, crawl routes, capture network, and probe interactions |
| **3** | Pick the path: `wget` mirror / template rebuild / **WebGL reverse-engineering** / theme market |
| **4** | Set up `~/projects/website-clones/<name>-clone/` (or your equivalent), keep `index-original.html` read-only |
| **5** | Strip tracking, write `NOTES.md` + `TEARDOWN.md`, verify in a real browser with screenshots |
| **6** | Replace text / media / brand colors with yours |

## License & attribution discipline

Before deploying anything publicly, **check the source repo's license**:

| License | What you can do |
|---|---|
| MIT / Apache / BSD / Unlicense | Modify, redeploy, just keep credits |
| **NONE / unstated** | Default = **All Rights Reserved**. Local learning only, must credit, **do not redeploy publicly without permission** |
| Proprietary / explicitly forbidden | Read-only learning, no copying, no deployment |

⚠️ "Code is on GitHub" ≠ "code is MIT". Many viral demos have no LICENSE file and default to All Rights Reserved.

## Flagship case

`marbles-case.md` documents the full reverse-engineering of [chiuhans111/marbles](https://github.com/chiuhans111/marbles) — a 1067-line single-file WebGL + SVG-filter glass marbles interactive demo — and contrasts the real architecture with an AI-generated clone analysis that got the core mechanism completely backwards. This is the canonical example of why you must verify against real source.

### 这个 skill 是干什么的

你看到一个喜欢的网站,想复刻 —— 学它怎么做、改成你自己的版本、或者离线跑起来。AI 工具最爱产出**看起来煞有其事**的"复刻分析文档",里面的代码块几乎全是臆造的,照抄必崩。

这个 skill 把"真源码至上"做成可重复的流程,**6 步决策树**覆盖三大分支:
- 静态 HTML/CSS 站 → `wget --mirror`
- React / Vue / Next 内容站 → 重建模板灌内容
- **WebGL / Canvas / Three.js 重前端** → 逆向真源码,逐行核对;找不到源码时用运行时帧捕获 + **baseline-first 复现闸门** + `SOURCE/PARTIAL/GUESS` 证据分级
- **静态构建站(Astro/Vite SSG/Hugo),哪怕重 WebGL** → `mirror-site.mjs` 全程滚动捕获 + 镜像每一个部署资产(含运行时 fetch 的 `.sog/.buf/.wasm`),做真 1:1 忠实复刻——对静态站,"拿到真源码"="镜像部署资产整套"(范例:Lusion oryzo.ai,高斯泼溅,hero 像素 diff 5/5)
- **视觉复刻 / 内容爆改模式** → 把"那个站的感觉"蒸馏成可版本化的 `design-dna.json`(设计 token + 风格 + 特效),然后"DNA 留着、内容换掉"
- 浏览器真验证,如实记录,最后替换成你自己的内容

### 头号铁律:真源码至上,绝不抄 AI 臆造代码

> 任何 AI 写的"复刻分析",**概念骨架可以参考,但里面的可执行代码块默认全是臆造的**,必须用真源码核对,否则照抄必崩。

**实证案例**:一份 AI 分析文档把原站"解析法求光线-球体交点 + 把光学结果编码成位移图 + 交给 SVG `feDisplacementMap` 扭曲真实 DOM"的真架构,臆造成了"ray-marching + SDF + 把 DOM 当纹理采样"—— 两套完全不同的实现,照抄做不出原效果且慢 N 倍。详见 `references/marbles-case.md`。

### 安装

这是一个 [Claude Code skill](https://docs.claude.com/en/docs/agents-and-tools/skills)。clone 到你的 skills 目录:

```bash
git clone https://github.com/Jane-xiaoer/claude-skill-web-clone.git ~/.claude/skills/web-clone
```

然后跟 Claude / Codex / Cursor 说:
- 「复刻这个网站: https://...」
- 「把这个站抄下来改成我的」
- 「逆向拆解这个 WebGL demo」

AI 会自动加载 `SKILL.md` 走决策树。

### 旗舰范例

`references/marbles-case.md` 拆解了 [chiuhans111/marbles](https://github.com/chiuhans111/marbles) —— 1067 行单文件 WebGL + SVG filter 玻璃弹珠站,真架构对比 AI 分析文档的错误,是"为什么必须真源码核对"的标准教材。
