Stats Dashboard Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 重新设计 StatsView.vue 数据统计页面，采用赛博朋克风格的迷你图表布局

Architecture: 单页垂直滚动布局，6个模块垂直排列，每个模块包含汇总数字卡片和迷你趋势图。复用现有 CSS 变量和 ChatView.vue 的设计模式。使用纯 CSS 实现迷你图表（条形图/折线图），避免引入新的图表依赖。

Tech Stack: Vue 3 + TypeScript + Pinia + lucide-vue-next（已有）+ echarts（已有，但优先用CSS实现）

Task 1: 创建 SectionHeader 组件

Files:

• Create: frontend/src/components/stats/SectionHeader.vue

• Modify: frontend/src/views/StatsView.vue（引入组件）

• Step 1: 创建 SectionHeader.vue

<script setup lang="ts">
defineProps<{
  title: string
  tag?: 'cyan' | 'purple' | 'amber'
}>()
</script>

<template>
  <div class="section-header">
    <div class="section-title">
      <span class="section-slash">//</span>
      <span class="section-name">{{ title }}</span>
    </div>
    <span v-if="tag" class="section-tag" :class="tag">
      {{ title.split(' ')[0] }}
    </span>
  </div>
</template>

<style scoped>
.section-header {
  display: flex;
  align-items: center;
  justify-content: space-between;
  padding: 16px 0 12px;
  border-bottom: 1px solid var(--border-dim);
  margin-bottom: 16px;
}

.section-title {
  font-family: var(--font-mono);
  font-size: 12px;
  letter-spacing: 0.1em;
}

.section-slash {
  color: var(--text-dim);
  margin-right: 8px;
}

.section-name {
  color: var(--text-primary);
  text-transform: uppercase;
}

.section-tag {
  padding: 3px 10px;
  border-radius: 3px;
  font-family: var(--font-display);
  font-size: 9px;
  font-weight: 600;
  letter-spacing: 0.12em;
  text-transform: uppercase;
}

.section-tag.cyan {
  background: var(--accent-cyan-dim);
  color: var(--accent-cyan);
  border: 1px solid rgba(0, 245, 212, 0.2);
}

.section-tag.purple {
  background: var(--accent-purple-dim);
  color: var(--accent-purple);
  border: 1px solid rgba(123, 44, 191, 0.2);
}

.section-tag.amber {
  background: var(--accent-amber-dim);
  color: var(--accent-amber);
  border: 1px solid rgba(249, 168, 37, 0.2);
}
</style>

• Step 2: 在 StatsView.vue 中引入并使用 SectionHeader

在 <script setup> 中添加:

import SectionHeader from '@/components/stats/SectionHeader.vue'

在模板中使用:

<SectionHeader title="SYSTEM HEALTH" tag="cyan" />

Task 7: 添加缺少的 CSS 变量（如需要）

Files:

• Modify: frontend/src/style.css

• Step 1: 检查并添加缺失的 CSS 变量

如果 --accent-purple 不存在，添加：

--accent-purple: #a855f7;
--accent-purple-dim: rgba(123, 44, 191, 0.15);

---

Task 8: 验证与测试

Files:

• Test: frontend/src/views/StatsView.vue

• Test: frontend/src/components/stats/*.vue

• Step 1: 运行 TypeScript 检查

cd frontend && npx vue-tsc --noEmit

• Step 2: 运行开发服务器测试

cd frontend && npm run dev

• Step 3: 验证页面渲染
• 打开 http://localhost:5173/stats
• 确认无 console errors
• 确认页面布局正确

执行选项

1. Subagent-Driven (推荐) - 我为每个任务派遣独立的子代理，任务间进行审查，快速迭代

2. Inline Execution - 在当前会话中按批次执行任务
