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 | $0.00060 | $0.00936 |
| Opus 5 | $0.00030 | $0.00468 |
| Sonnet 5 | $0.00012 | $0.00187 |
| Haiku 4.5 | $0.00006 | $0.00094 |
Grade A, and why
frontend-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 today.
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
MiddleTool Frontend Design
基于 Anthropic frontend-design，针对本项目的约束扩展。
产品定位
- 是什么：桌面端中间件连接管理器，导出 MCP 配置给 Codex
- 受众：开发者 / 运维，在本地 Electron 中高频操作
- 参考气质：VS Code 设置、Linear 内部工具、Raycast — 不是 SaaS 营销页

禁止（AI slop）
- Emoji 作为导航主图标（🚀📋◉⬡ 等）
- 大面积紫色/靛蓝渐变、发光阴影、
box-shadow装饰 - 三列等大「统计卡片」+ 超大数字（32px+）作为首页主视觉
- Inter / 系统默认无个性堆叠 + 千篇一律的
border-radius: 12px卡片墙 - 空洞营销文案（「统一管理」「赋能」）；改用动词和操作结果
组件模式
侧边栏
- 左栏固定宽度 ~220px，品牌区一行标题 + 一行副标题（小字、muted）
- 导航项：文字为主，激活态用 左侧 2px accent 竖条，不用整块紫色底
- 图标：几何/CSS 标记或省略，不用 emoji
概览页
- 指标区：横向 metrics 条（label + value 一行），等宽分隔，mono 数字
- 快捷操作：列表行（标题、说明、右侧按钮），非卡片网格
- 信息密度适中，留白用于分组而非装饰
表单与列表
- 字段分组用细线标题，不用大色块
- 主按钮仅一个强调色；次要操作为 ghost/outline
- 表格/列表 hover 用
--bg-hover，无动画花哨
流程
- 先确认页面任务（用户要完成什么操作）
- 用上述 token，不引入新色除非有理由
- 改完后自检：是否像「AI 生成的深色 SaaS」？若是，减圆角、减渐变、减装饰
- 保持
prefers-reduced-motion、键盘 focus 可见
与全局 CSS 的关系
- 令牌定义在
src/index.css:root - 布局在
AppLayout.css，页面在各自*.css - 新页面复用
.page-header、.btn-primary、.card，不重复造变量
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.

frontend-design is a skill published in the GitHub repository 2514385224/middle-tool (4 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 936 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 2026-09-12.
