design-clone

design-clone is a skill for Claude Code from XRenSiu/claude-code-forge. It costs 197 tokens per session (11,434 once invoked), scanned A, original, MIT.

A website design-analysis and cloning tool that extracts a structured profile of a site’s visual rules, such as colors, fonts, spacing, shapes, shadows, and effects. It can also use that profile to create a close code-based copy.

In plain words
What is it for?
Use it to analyze one or more website URLs, export their design profile, or build a visual clone of the site.
Why use it?
It turns a site’s visual appearance into reusable design information instead of relying on guesses.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-clone scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Design Clone — Design DNA 提取 × 像素级克隆

你被调用来处理 $ARGUMENTS:可能是提取一份结构化的三维设计画像(Design DNA JSON),可能是完整克隆一个网站的源码,也可能两者都要。

这份 skill 提供两项核心能力:

  • 精确提取:用 Browser MCP 注入 JS,通过 getComputedStyle() 读取像素级精确 CSS 值,零猜测
  • 结构化表达:用三维 schema(150+ 字段)把提取到的原始值归类成可复用的设计画像

📖 参考:references/schema.md — 三维 schema 完整字段定义;references/generation-guide.md — DNA JSON → 代码的映射规则。

开始时告诉用户: "I'm using the design-clone skill to extract a Design DNA profile [and clone the site]."


模式识别(必须首先做)

解析 $ARGUMENTS,识别两类信息:

  1. 模式标志
    • 出现 --dna-only → 仅提取设计数据,执行 Phase 0–3 即完成
    • 出现 --full 或没有标志 → 完整克隆,执行 Phase 0–6
  2. URL 列表:剩余参数都是 URL。规范化、验证可访问。

多 URL 处理:

  • --dna-only 多 URL:询问用户是并行处理输出多份 DNA,还是合并为一份 DNA(识别主导模式并标注差异)
  • --full 多 URL:每个站点独立处理,产物隔离到 docs/research/<hostname>/

把识别结果作为首条状态输出给用户:

Mode: --dna-only
Targets: [url1, url2]
Merge strategy: combine into one DNA (dominant pattern + variants)

两种模式的执行路径

/design-clone --dna-only <url>          /design-clone --full <url>(或省略标志)

                                         ✅ 输出 DNA JSON + 克隆源码

核心原则: --dna-only 模式跑同样的 JS 提取脚本获取精确数据,但数据流向 DNA JSON,而非写入 Next.js 项目。Phase 1 两种模式完全一样——DNA 的第一维和第三维都依赖 Phase 1 的精确数据和交互行为记录。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-clone is a skill published in the GitHub repository XRenSiu/claude-code-forge (2 stars, last pushed 29d ago), licensed MIT. It adds 197 tokens to every session and 11,434 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
