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

ucss 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 2d 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.

css rules

ucss是css的子集,但可以跨平台使用。除了浏览器之外,还支持App原生平台。

布局规范

  • 禁用浮动、网格等布局,仅使用flex布局或绝对定位。
  • flex布局默认方向为垂直(通过 flex-direction:column 实现)。

选择器规则

  • 仅支持基本的类选择器 (.class),禁止使用其他选择器。
  • 类名必须符合 [A-Za-z0-9_-]+ 规范,禁止使用特殊字符(例如 @class)。

文字样式规则

  • 文字内容需放置在组件 或 中。文字类样式(color、font-size)只能设置在 或 组件上。 其他组件(如)禁止设置文本相关样式。
  • 文字样式不继承。
  • 禁用继承相关关键字,例如 inherit 和 unset。

层级控制

  • z-index 仅对同级兄弟节点生效。
  • absolute 固定位与文档流分离,不支持分层覆盖。

长度单位

  • 仅支持px、rpx、百分比。字体的line-height支持em。不能使用其他单位,如vh。
  • 除非width需要根据屏幕宽度而变化才使用rpx单位。其他场景不使用rpx单位。
  • 除非长度单位需要根据父容器大小而变化才使用百分比单位。其他场景不使用rpx单位。

at-rules

  • 仅支持@font-face@import,不使用其他at-rules。
  • 如需使用@media 适配不同屏幕,改用 uts 代码实现,先通过API uni.getWindowInfo获取屏幕宽度, 再通过代码进行适配。
  • 如需使用@media 适配暗黑模式, 改用 uts 代码 和 css变量 实现。
  • 如需使用@keyframes,改为通过UniElement对象的animate方法实现相同逻辑。

css function

  • 仅支持 url()、rgb()、rgba()、var()、env(),不使用其他css方法。

样式作用范围规则

  • 不使用css scoped。

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.
