## 📄 页面设计

### 1. Dashboard（智能体大厅）

```tsx
// pages/Dashboard.tsx

import { IntentSearch } from '../components/IntentSearch';
import { AgentPipeline } from '../components/AgentPipeline';

export const Dashboard: React.FC = () => {
  return (
    <div className={styles.dashboard}>
      {/* 顶部意图搜索框 */}
      <header className={styles.header}>
        <h1>AI 智能助手</h1>
        <p>有什么可以帮助您的？</p>
        <IntentSearch />
      </header>
      
      {/* 5阶段智能体流水线 */}
      <main className={styles.main}>
        <AgentPipeline />
      </main>
    </div>
  );
};
```

**布局特点**：
- 顶部居中大搜索框
- 5阶段流水线横向平铺（桌面）/ 纵向滚动（移动）
- Gemini 风格大留白

---

### 2. Workspace（对话工作台）

```tsx
// pages/Workspace.tsx

import { ChatContainer } from '@/shared/components/Chat';
import { ConversationList } from '../components/ConversationList';
import { ThinkingBlock } from '../components/MessageList/ThinkingBlock';
import { AttachmentUpload } from '../components/Attachment/AttachmentUpload';

export const Workspace: React.FC = () => {
  const { conversationId } = useParams();
  const { conversation, messages, sendMessage } = useConversation(conversationId);
  
  return (
    <div className={styles.workspace}>
      {/* 左侧边栏 - 历史会话 */}
      <aside className={styles.sidebar}>
        <ConversationList />
      </aside>
      
      {/* 主对话区 */}
      <main className={styles.main}>
        {/* 对话头部 */}
        <header className={styles.header}>
          <AgentAvatar agent={conversation?.agent} />
          <h2>{conversation?.agent?.name}</h2>
        </header>
        
        {/* 消息列表 - 复用通用 Chat 组件 */}
        <ChatContainer
          messages={messages}
          onSend={sendMessage}
          renderMessage={(msg) => (
            <div className={styles.message}>
              {/* 深度思考块 */}
              {msg.thinkingContent && (
                <ThinkingBlock content={msg.thinkingContent} />
              )}
              {/* 消息内容 */}
              <MarkdownRenderer content={msg.content} />
              {/* 附件卡片 */}
              {msg.attachments?.map(att => (
                <AttachmentCard key={att.id} attachment={att} />
              ))}
            </div>
          )}
          inputFooter={<AttachmentUpload />}
        />
      </main>
    </div>
  );
};
```

## 🧩 组件详细设计

### 1. AgentPipeline（5阶段流水线）

```tsx
// components/AgentPipeline/index.tsx

interface AgentPipelineProps {
  onAgentClick: (agentId: string) => void;
}

export const AgentPipeline: React.FC<AgentPipelineProps> = ({ onAgentClick }) => {
  const { agents } = useAgents();
  
  const stages = [
    { key: 'design', title: '研究设计', color: 'var(--stage-design)' },
    { key: 'data', title: '数据采集', color: 'var(--stage-data)' },
    { key: 'analysis', title: '统计分析', color: 'var(--stage-analysis)' },
    { key: 'write', title: '论文撰写', color: 'var(--stage-write)' },
    { key: 'publish', title: '成果发布', color: 'var(--stage-publish)' },
  ];
  
  return (
    <div className={styles.pipeline}>
      {stages.map((stage, index) => (
        <StageColumn
          key={stage.key}
          title={stage.title}
          color={stage.color}
          agents={agents.filter(a => a.stage === stage.key)}
          onAgentClick={onAgentClick}
          showConnector={index < stages.length - 1}
        />
      ))}
    </div>
  );
};
```

**样式特点**：
```css
.pipeline {
  display: flex;
  gap: var(--spacing-lg);
  overflow-x: auto;
  padding: var(--spacing-xl) 0;
}

/* 移动端纵向布局 */
@media (max-width: 768px) {
  .pipeline {
    flex-direction: column;
    overflow-x: visible;
  }
}
```

---

### 2. IntentSearch（意图搜索框）

```tsx
// components/IntentSearch/index.tsx

export const IntentSearch: React.FC = () => {
  const [query, setQuery] = useState('');
  const [suggestions, setSuggestions] = useState<IntentSuggestion[]>([]);
  const { routeIntent, isLoading } = useIntentRouter();
  const navigate = useNavigate();
  
  // 500ms 防抖
  const debouncedQuery = useDebouncedValue(query, 500);
  
  useEffect(() => {
    if (debouncedQuery.length >= 2) {
      routeIntent(debouncedQuery).then(setSuggestions);
    }
  }, [debouncedQuery]);
  
  const handleSelect = (suggestion: IntentSuggestion) => {
    // 跳转到对应智能体
    navigate(`/aia/workspace?agent=${suggestion.agentId}&prompt=${encodeURIComponent(suggestion.prefillPrompt)}`);
  };
  
  return (
    <div className={styles.searchContainer}>
      <Input.Search
        size="large"
        placeholder="描述您的需求，AI 将为您推荐合适的助手..."
        value={query}
        onChange={(e) => setQuery(e.target.value)}
        loading={isLoading}
        className={styles.searchInput}
      />
      
      {suggestions.length > 0 && (
        <SuggestionDropdown
          suggestions={suggestions}
          onSelect={handleSelect}
        />
      )}
    </div>
  );
};
```

### 3. ThinkingBlock（深度思考折叠块）

```tsx
// components/MessageList/ThinkingBlock.tsx

interface ThinkingBlockProps {
  content: string;
  duration?: number;  // 思考耗时（秒）
  isStreaming?: boolean;  // 是否正在生成
}

export const ThinkingBlock: React.FC<ThinkingBlockProps> = ({
  content,
  duration,
  isStreaming = false,
}) => {
  // 生成中展开，完成后自动收起
  const [expanded, setExpanded] = useState(isStreaming);
  
  useEffect(() => {
    if (!isStreaming && expanded) {
      // 完成后 1.5s 自动收起
      const timer = setTimeout(() => setExpanded(false), 1500);
      return () => clearTimeout(timer);
    }
  }, [isStreaming]);
  
  return (
    <div className={styles.thinkingBlock}>
      <div 
        className={styles.header}
        onClick={() => setExpanded(!expanded)}
      >
        <span className={styles.icon}>
          {isStreaming ? <LoadingOutlined spin /> : <BulbOutlined />}
        </span>
        <span className={styles.title}>
          {isStreaming ? '正在深度思考...' : `已深度思考 (耗时 ${duration?.toFixed(1)}s)`}
        </span>
        <span className={styles.expandIcon}>
          {expanded ? <UpOutlined /> : <DownOutlined />}
        </span>
      </div>
      
      {expanded && (
        <div className={styles.content}>
          <Typography.Text type="secondary">
            {content}
          </Typography.Text>
        </div>
      )}
    </div>
  );
};
```

**样式**：
```css
.thinkingBlock {
  background: var(--thinking-bg);
  border: 1px solid var(--thinking-border);
  border-radius: 8px;
  margin-bottom: var(--spacing-md);
}

.header {
  display: flex;
  align-items: center;
  padding: var(--spacing-sm) var(--spacing-md);
  cursor: pointer;
  user-select: none;
}

.content {
  padding: var(--spacing-md);

export const AttachmentUpload: React.FC<AttachmentUploadProps> = ({
  conversationId,
  onUploadComplete,
  maxCount = 5,
}) => {
  const { uploadFile, uploading, progress } = useAttachment();
  const [attachments, setAttachments] = useState<Attachment[]>([]);
  
  const handleUpload = async (file: File) => {
    if (attachments.length >= maxCount) {
      message.error(`最多上传 ${maxCount} 个附件`);
      return false;
    }
    
    // 文件类型校验
    const allowedTypes = ['application/pdf', 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'text/plain', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'];
    if (!allowedTypes.includes(file.type)) {
      message.error('仅支持 PDF、Word、TXT、Excel 文件');
      return false;
    }
    
    // 文件大小校验（20MB）
    if (file.size > 20 * 1024 * 1024) {
      message.error('文件大小不能超过 20MB');
      return false;
    }
    
    const attachment = await uploadFile(conversationId, file);
    setAttachments([...attachments, attachment]);
    onUploadComplete(attachment);
    return false;  // 阻止默认上传

      {/* 已上传附件列表 */}
      <div className={styles.attachmentList}>
        {attachments.map(att => (
          <AttachmentCard
            key={att.id}
            attachment={att}
            onRemove={() => {

## 📱 响应式设计

### 断点策略

```typescript
// 断点定义
const breakpoints = {
  sm: 640,   // 手机
  md: 768,   // 平板（主要断点）
  lg: 1024,  // 桌面
  xl: 1280,  // 大屏
};
```

### Dashboard 响应式

| 断点 | 布局 |
|------|------|
| `< 768px` | 流水线纵向滚动，卡片单列 |
| `≥ 768px` | 流水线横向 5 列 |

### Workspace 响应式

| 断点 | 布局 |
|------|------|
| `< 768px` | 侧边栏隐藏（抽屉滑出），输入框键盘适配 |
| `≥ 768px` | 侧边栏固定显示 240px |
