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 | $0.00097 | $0.01337 |
| Opus 5 | $0.00048 | $0.00668 |
| Sonnet 5 | $0.00019 | $0.00267 |
| Haiku 4.5 | $0.00010 | $0.00134 |
Grade A, and why
anybox-frontend-guidelines 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.

Anybox 前端规范
核心流程
- 修改前先阅读目标 UI 代码。优先沿用已有组件结构、class 命名、CSS 归属和 token 用法，不要先发明新抽象。
- 按组件的交互职责、状态模型和 ARIA role 判定 semantic token 归属，再到 schema v2 manifest 中找到对应 component/product token 组并列出完整状态组合。复用现有 class 只代表复用结构，不会改变组件的 semantic token 归属。
- 只读取当前任务需要的 reference：
- 产品整体风格：
references/principles.md - token、CSS 归属、主题规则：
references/tokens-and-css.md - shell、pane、sidebar、surface：
references/layout-and-surfaces.md - 按钮、菜单、控件、列表行：
references/controls-and-menus.md - 槽位式卡片列表交互：
references/slot-card-list.md - ThreadView、trace、branch、composer：
references/thread-view.md - 设置、插件、MCP、global skills 页面：
references/settings-and-management.md - UI 修改完成前检查：
references/implementation-checklist.md
- 产品整体风格：
- 以本地项目文件和可执行校验为事实来源。常用入口：
C:/Projects/Anybox/packages/desktop/src/shared/appearance-token-manifest.jsonC:/Projects/Anybox/packages/desktop/scripts/generate-appearance-tokens.mjsC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/tokens.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/primitives.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/shell.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/sidebar.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/workbench.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/thread.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/composer.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/settings.cssC:/Projects/Anybox/packages/desktop/src/renderer/src/styles/responsive.css
- 保持改动范围收敛。优先改 token 或局部语义 class，不要追加文件末尾的大范围覆盖规则。新增或扩充 semantic token 组时，范围必须包含同语义消费者盘点：迁移所有命中的组件，或明确记录暂不迁移的例外，不能只修改一个示例组件后宣称该 token 组已接入。
- 最终回复前检查亮色/暗色主题、窄窗口、键盘焦点、溢出和相关测试。
撰写 UI 规范的元规则
新增或改写本 skill 的 UI 组件/交互 reference 时，必须让规范自包含这些主题与 token 约束，不要只依赖通用 token 文档：
- 明确 light 和 dark 双主题都必须支持。
- 明确组件 CSS 只消费不带
-light/-dark后缀的运行时 token。 - 明确每类组件及其子部件分别归属哪个 semantic token 组，并要求完整覆盖该组适用的 default、hover、focus、active、selected、disabled、invalid 等状态；不能借用其他组件组或基础色 token 代替已有的本组件语义。
- 明确复用 shared/context/menu class 时只复用布局、尺寸、排版和行为；颜色状态仍必须服从当前组件的 semantic token 组。组合组件按子部件分别归属，例如 picker trigger 使用按钮 token、搜索输入使用 field token、展开面板和选项使用 dropdown token。
- 明确 semantic token 的命名、fallback 与 light/dark 映射规则。
- 明确缺少合适 token 时，先在 schema v2 manifest 补充成对 light/dark semantic token，再运行生成器；不要在
tokens.css创建第二份颜色定义。 - 明确新增或扩充 semantic token 组后必须全仓盘点对应交互角色、ARIA role、组件 class 和旧 token 消费者，并增加正向消费断言与禁止跨组回退的负向断言。
- 明确公开主题值只允许 DTCG
literal或 mode-tokenalias；内部 blend 仅用于无法由 literal/alias 表达的受控派生，并禁止组件直接消费--mix-*。 - 明确 default、hover、focus、active、disabled、selected/current、error/invalid 等状态都要在明暗主题下可读。
- 明确禁止硬编码颜色和硬编码 fallback，例如
#fff、#000、固定灰色、固定品牌色或rgba(...)。 - 明确 focus 使用组件自身的背景、边框、文字、指示器等 token 化状态表达，不使用 outline 或 inset ring。

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.

anybox-frontend-guidelines is a skill published in the GitHub repository fanfan-de/anybox (57 stars, last pushed 29d ago), licensed MIT. It adds 97 tokens to every session and 1,337 once invoked, about $0.0005 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.
