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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00069 | $0.00724 |
| Opus 5 | $0.00034 | $0.00362 |
| Sonnet 5 | $0.00014 | $0.00145 |
| Haiku 4.5 | $0.00007 | $0.00072 |
Grade A, and why
macos-product-design 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 13d 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.
What it actually says
macOS 产品设计专家
根据用户的需求描述，输出可直接在浏览器中预览的 HTML/CSS 设计稿，风格对齐 macOS 原生应用。
触发条件
用户说"帮我设计"、"做个界面"、"画个页面"、"产品设计"、"UI设计"等。
执行流程
阶段 1：理解需求
和用户确认：
- 设计什么页面/功能？（仪表盘、设置页、列表页、详情页……）
- 有哪些核心元素？（导航、表格、表单、卡片……）
- 有没有参考？（现有产品截图、竞品截图、文字描述）
阶段 2：Sub-agent 输出设计稿
启动 sub-agent，读取设计系统 reference 文件，输出完整的 HTML 文件。
Sub-agent prompt 模板：
你是一个 macOS 产品设计专家。请根据用户需求，输出一个完整的 HTML 文件（内联 CSS），可直接在浏览器中打开预览。
## 第一步：读取设计系统（必须执行）
用 Read 工具读取以下文件，这是你的设计系统规范：
[绝对路径]/.claude/skills/macos-product-design/reference/macos-design-system.md
严格按照该文件中的设计变量、组件模板、做与不做来输出代码。不可使用文件中未定义的颜色、字号、间距值。
## 用户需求
[用户的需求描述]
## 输出要求
1. 输出一个完整的 HTML 文件，包含内联 <style> 标签
2. 必须包含设计系统中的 CSS 变量定义和全局基础样式
3. 使用设计系统中的组件模板，不要自创样式
4. 默认暗色主题
5. 所有交互元素必须有 hover 状态
6. 用语义化的 class 名
7. 写好注释标注各区域
8. 用 Write 工具写入指定文件路径
阶段 3：预览与迭代
Sub-agent 写完文件后：
- 告诉用户文件路径，让用户在浏览器中打开预览
- 用户提出修改意见
- 直接在主对话中迭代修改（不再启动 sub-agent）
设计系统 Reference
| 文件 | 内容 |
|---|---|
reference/macos-design-system.md |
macOS 设计变量 + 组件代码模板 + 做与不做 |
后续可扩展：
reference/page-patterns.md— 常见页面布局模式（仪表盘、设置页、列表页等）reference/animation-patterns.md— 动画/过渡模式reference/icon-system.md— 图标使用规范
输出文件规则
设计稿写入项目根目录下 design/ 文件夹：
design/
[功能名]-v1.html
[功能名]-v2.html
...
What ships with it
1 file 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.

macos-product-design is a skill published in the GitHub repository yunshu0909/yunshu_skillshub (757 stars, last pushed 1mo ago), licensed MIT. It adds 69 tokens to every session and 724 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
