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

ui-designer 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 12d 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

UI Designer

执行前读取 工作流执行约定:先取证再提问、按实际工具能力回退,并从本次安装位置定位资源。

决定产品界面长什么样、用起来是什么感觉:从口述需求、PRD/User Journey、截图或品牌材料中判读风格、构图、组件和交互,产出设计语言、组件规格和可运行的高保真界面。执行细则见 ui-designer。

使用方式

直接描述你要做的产品、用户和页面,或提供 PRD/User Journey 路径;截图、参考网站、品牌材料和前端仓库路径都可以附上:

$ARGUMENTS

核心特点

  • 自己判读设计:从使用频率、设备、任务、数据形态、行业语境等信号推出视觉性格、构图、组件和交互,写出带依据的判读单后直接动手
  • 方向开放时给出真实选择:把两个真正不同的方向做成同一个代表页,比较后再定
  • 有立场的设计语言:六层视觉语言逐层独立决定,生成默认样式须事前声明依据,并用测量证据核对
  • 可以落地:token、组件规格(含状态)和交互编排写到开发能照做;有仓库时用仓库技术栈写进隔离沙箱,可直接交给 prototype-designer
  • 不需要仓库也能用:没有前端仓库时输出独立设计包,页面可直接在浏览器打开

工作流程

  1. 输入与约束:建立需求基线(正式文档或需求推断卡),判断仓库模式或独立模式,读取品牌与已有设计
  2. 判读与方向:设计判读;方向开放时做两个方向的代表页供选择
  3. 设计语言:六层视觉语言与 token、逐页设计决策、组件规格、交互编排
  4. 实现与打磨:代表页过门槛,扩展关键页面与状态,四遍观察、测量、交互实测与修正复验
  5. 交付:设计包与交接说明;需要验证完整流程与状态时,接着执行 /testany-eng:prototype-designer

提供需求描述或文档路径即可开始设计。

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.

ui-designer is a command published in the GitHub repository TestAny-io/testany-agent-skills (82 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 612 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 2026-10-12.
