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 | $0.00000 | $0.01783 |
| Opus 5 | $0.00000 | $0.00892 |
| Sonnet 5 | $0.00000 | $0.00357 |
| Haiku 4.5 | $0.00000 | $0.00178 |
Grade A, and why
hf-ui-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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UI 设计
有 UI 的特性在 to-spec / implement / 代码评审时加载本技能。
加载
- 绑定阶段: to-spec、implement、code-review
- 触发条件: 特性包含用户界面(页面 / 组件 / 可视交互)
设计层（先于一切视觉工作执行）
本技能在进入具体 UI 工作前，必须先过设计层三件事：
1. 确定美学方向（禁止"默认模板脸"）
- 任何 UI 特性先选定单一明确的美学方向：editorial（编辑风）、swiss/极简、brutalist、retro-futuristic、dark luxury、soft/极简暖色、neo-brutalism、有机形态 等，选一个并写进
spec.md的 UI 设计节。 - 调用本合集的
ui-ux-pro-max技能做风格与设计系统匹配（240+ 风格库、字体配对、UX 指南，含桌面），再调用frontend-design技能（官方版）做方向确认与真实排版配对（serif/sans/mono 的组合，拒绝只换一个无衬线字体）。 - 方向一旦确定，后续阶段禁止漂移回通用 SaaS 模板；评审时以此方向为基准。
2. 用 taste 旋钮校准
- 按
taste-skill的DESIGN_VARIANCE/MOTION_INTENSITY/VISUAL_DENSITY三旋钮给出明确取值（默认 3/2/3，范围 1–5），写入 spec 或 DESIGN.md。 - 动效只服务交互语义；装饰性动效一律拒绝。
3. DESIGN.md
- 绿地项目（无既有设计系统 / 无
DESIGN.md）必须在 to-spec 阶段创建DESIGN.md：一行品牌立场 + 色彩（含 OKLCH 推导）+ 字体配对 + 间距/圆角/阴影标尺 + 3 条以上禁止项。 - 有既有
DESIGN.md或设计系统时，先冷读再复用，禁止另起炉灶。 - 生成与维护参考
references/design-rules.md与stitch-skill。
规格阶段 (to-spec) 规则
spec.md 的实现决策 / 测试决策或专设的 UI 设计 一节须覆盖：
信息架构与交互先行
- 先锁定页面结构、导航与内容分组，再进入组件与视觉细节
- 每个关键交互至少覆盖 loading / empty / error 三态；高风险交互补齐 disabled / success / focus
- 只绘制顺利路径视为不完整
视觉系统与令牌纪律
- 有既有设计系统 / 品牌规范或
DESIGN.md时，必须先冷读并复用 - 颜色、字号、间距、圆角、阴影一律使用设计令牌，禁止硬编码字面量
- 有
DESIGN.md或既有令牌文件时优先从中取值；没有时先在规格中命名令牌 - 缺资产时用语义占位符，不自画 SVG、不自编正文
反 AI 粗制滥造审美（硬拒绝项）
除非用户在决策记录/ADR 中明确要求，否则拒绝：无理由的紫色渐变、Inter/Roboto 默认字体、带左侧彩条的圆角卡片式提示框、用 emoji 充当图标、无理由的发光效果、装饰性动效、大面积玻璃拟态、无法回指需求的分区/徽标，以及没有 CTA 的空状态。
可访问性底线
- 正文对比度达到 WCAG AA；键盘可达且焦点可见；纯图标控件须有
aria-label；触控目标 ≥ 44×44px - 详见
references/ui-checklist.md
实现阶段 (implement) 规则
- UI 相关票的测试覆盖交互三态可验证行为
- 令牌纪律延续到代码；在重构步骤中清理硬编码
- 按已确定的 DESIGN.md 与美学方向实现；色调、字体、间距全部来自令牌，不引入新的系统字体默认
- 提请进入
code-review阶段前，加载references/ui-checklist.md自查
视觉验证闭环（实现完成 + 评审时强制执行）
只有单元测试不构成 UI 验证。每个含 UI 的特性必须走：
- 真实渲染：启动应用并截图（Web 用浏览器截图，桌面用应用截图），覆盖主页面 + 至少一个三态。
- 截图评审：把截图交给评审，按
references/design-rules.md的评审框架逐项过：- 方向一致性（是否回到"模板脸"）
- 排版节奏与字体配对是否成立
- 间距层次、留白、对齐网格
- 色彩对比与令牌使用
- 空状态 / loading / error 是否可看
- 平台规范（Web 或桌面各自的要求）
- 回修：评审发现视觉硬伤 → 返回实现阶段修复 → 重新截图复验，直到无方向漂移、无模板脸、无视觉硬伤。
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.

hf-ui-design is a skill published in the GitHub repository hujianbest/harness-flow (53 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,783 tokens. 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.
