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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00052 | $0.02750 |
| Opus 5 | $0.00026 | $0.01375 |
| Sonnet 5 | $0.00010 | $0.00550 |
| Haiku 4.5 | $0.00005 | $0.00275 |
Grade A, and why
frontend-ui-engineering 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.

前端 UI 工程
概览
构建既可访问、又高性能、而且视觉完成度高的生产级用户界面。目标是让 UI 看起来像出自一家优秀公司的设计感工程师之手,而不是像 AI 随手拼出来的东西。这意味着要真正遵守设计系统、认真处理可访问性、设计合理的交互模式,并彻底避免通用的 “AI 审美”。
何时使用
- 构建新的 UI 组件或页面
- 修改现有用户界面
- 实现响应式布局
- 添加交互或状态管理
- 修复视觉或 UX 问题
组件架构
文件结构
把与组件相关的内容就近放在一起:
src/components/
TaskList/
TaskList.tsx # Component implementation
TaskList.test.tsx # Tests
TaskList.stories.tsx # Storybook stories (if using)
use-task-list.ts # Custom hook (if complex state)
types.ts # Component-specific types (if needed)
组件模式
优先组合,而不是堆配置:
// Good: Composable
<Card>
<CardHeader>
<CardTitle>Tasks</CardTitle>
</CardHeader>
<CardBody>
<TaskList tasks={tasks} />
</CardBody>
</Card>
// Avoid: Over-configured
<Card
title="Tasks"
headerVariant="large"
bodyPadding="md"
content={<TaskList tasks={tasks} />}
/>
让组件保持聚焦:
// Good: Does one thing
export function TaskItem({ task, onToggle, onDelete }: TaskItemProps) {
return (
<li className="flex items-center gap-3 p-3">
<Checkbox checked={task.done} onChange={() => onToggle(task.id)} />
<span className={task.done ? 'line-through text-muted' : ''}>{task.title}</span>
<Button variant="ghost" size="sm" onClick={() => onDelete(task.id)}>
<TrashIcon />
</Button>
</li>
);
}
把数据获取和展示分开:
// Container: handles data
export function TaskListContainer() {
const { tasks, isLoading, error } = useTasks();
if (isLoading) return <TaskListSkeleton />;
if (error) return <ErrorState message="Failed to load tasks" retry={refetch} />;
if (tasks.length === 0) return <EmptyState message="No tasks yet" />;
return <TaskList tasks={tasks} />;
}
// Presentation: handles rendering
export function TaskList({ tasks }: { tasks: Task[] }) {
return (
<ul role="list" className="divide-y">
{tasks.map(task => <TaskItem key={task.id} task={task} />)}
</ul>
);
}
状态管理
选择刚好够用的最简单方案:
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.
- 7d ago First seen · 319 lines · 52 tokens per session scan A a6bb9d377c29
frontend-ui-engineering is a skill published in the GitHub repository 233i/agent-skills (6 stars, last pushed 5mo ago), licensed MIT. It adds 52 tokens to every session and 2,750 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 2026-08-31.
