Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00197 | $0.11434 |
| Opus 5.5 | $0.00079 | $0.04574 |
| Sonnet 5.5 | $0.00039 | $0.02287 |
| Haiku 4.5 | $0.00020 | $0.01143 |
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:
- 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
- 出现
- 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)
Phase 0: Pre-Flight (精简版) Phase 0: Pre-Flight (完整版)
↓ ↓
Phase 1: Reconnaissance Phase 1: Reconnaissance
↓ ↓
Phase 2: Foundation (仅提取,不写入) Phase 2: Foundation Build
↓ ↓
Phase 3: DNA Extraction Phase 3: DNA Extraction
↓ ↓
✅ 输出 design-dna.json 完成 Phase 4: Component Spec & Dispatch
↓
Phase 5: Page Assembly
↓
Phase 6: Visual QA
↓
✅ 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 ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
