+purpose: MessageCard 组件统一提取实现计划
+---
+
+# MessageCard 组件统一实现计划
+
+> **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:** 提取 MessageCard.vue 组件，统一 story-card 和 result-chat-list 中 AI 消息卡片的样式，并按 100 字阈值自动切换短消息/完整卡片模式
+
+**Architecture:** 新建 `MessageCard.vue` 组件封装长消息卡片结构，ScriptView.vue 中 story-card 和 result-chat-list 都复用该组件，短消息直接渲染简洁气泡
+
+**Tech Stack:** Vue 3, UniApp, 微信小程序
+
+---
+
+## 文件结构
+
+**创建：**
+- `mini-program/src/components/MessageCard.vue` - 通用 AI 消息卡片组件
+
+**修改：**
+- `mini-program/src/pages/main/ScriptView.vue` - 替换 story-card 和 result-chat-list 中的 assistant 消息渲染，并迁移相关样式
+
+---
+
+### Task 1: 创建 MessageCard.vue 组件（短消息模式 + 基础结构）
+
+**Files:**
+- Create: `mini-program/src/components/MessageCard.vue`
+- Modify: 无
+
+- [ ] **Step 1: 创建组件文件并写入基础模板**
+
+在 `mini-program/src/components/MessageCard.vue` 写入以下内容：
+
+```vue
+<template>
+  <view v-if="isShortMessage" class="chat-bubble system">
+    <text>{{ content }}</text>
+  </view>
+  <view v-else class="story-card" :class="{ collapsed }">
+    <view class="story-head">

+- [ ] **Step 2: 验证组件文件创建成功**
+
+确认文件路径：`mini-program/src/components/MessageCard.vue` 存在。
+
+```bash
+ls "G:/IdeaProjects/emotion-museun/mini-program/src/components/MessageCard.vue"
+```
+
+- [ ] **Step 3: 提交组件创建**
+
+```bash
+cd "G:/IdeaProjects/emotion-museun"
+git add mini-program/src/components/MessageCard.vue
+git commit -m "feat: 创建 MessageCard 组件
+
+封装长消息/故事卡片结构，支持短消息简洁气泡模式"
+```
+
+---
+
+### Task 2: 在 ScriptView.vue 中注册并使用 MessageCard 组件
+
+**Files:**
+- Modify: `mini-program/src/pages/main/ScriptView.vue`
+
+- [ ] **Step 1: 导入组件**
+
+在 `ScriptView.vue` 的 `<script setup>` 顶部，导入 MessageCard 组件：
+
+修改前：
+```javascript
+import { computed, nextTick, onMounted, onUnmounted, ref, watch } from 'vue'
+```
+
+修改后：
+```javascript
+import { computed, nextTick, onMounted, onUnmounted, ref, watch } from 'vue'
+import MessageCard from '../../components/MessageCard.vue'
+```
+
+- [ ] **Step 2: 替换 story-card 模板**
+
+找到第 172-219 行的 `story-card` 模板，替换为 MessageCard 组件。
+
+修改前：
+```vue
+<view class="story-card" :class="{ collapsed: storyCollapsed, dialogMode: resultHasScriptReplies }">
+  ...（原有 story-card 全部内容）...
+</view>
+```
+
+修改后：
+```vue
+<MessageCard
+  :content="displayedResultContent"
+  :title="currentResult?.title"
+  :tags="resultTags"
+  :collapsed="storyCollapsed"
+  :content-length="displayedResultContent.length"
+  :is-short-message="false"
+  :tts-icon="ttsActionIcon"
+  :tts-text="ttsActionText"
+  @toggle-collapse="toggleStoryCollapse"
+  @copy="copyResultContent"
+  @change-direction="changeDirection"
+  @not-like-me="notLikeMe"
+  @continue="continueInChat"
+  @play-tts="trackTtsClick"
+/>
+```
+
+- [ ] **Step 3: 替换 result-chat-list 中的 assistant 消息**
+
+找到第 221-254 行的 `result-chat-list` 模板，替换为使用 MessageCard。
+
+修改前：
+```vue
+<view v-if="resultMessages.length" class="result-chat-list">
+  <view
+    v-for="message in resultMessages"
+    :key="message.id"
+    class="chat-bubble"
+    :class="{ user: message.role === 'user', system: message.role === 'assistant', pending: message.pending }"
+  >
+    <text selectable user-select>{{ getMessageDisplayContent(message) }}</text>
+    <view v-if="message.pending" class="thinking-dots">

+      ...
+    </view>
+    <text class="bubble-time">{{ message.time }}</text>
+  </view>
+</view>
+```
+
+修改后：
+```vue
+<view v-if="resultMessages.length" class="result-chat-list">
+  <view
+    v-for="message in resultMessages"
+    :key="message.id"
+  >
+    <MessageCard

+      :collapsed="isMessageCollapsed(message)"
+      :content-length="message.content.length"
+      :is-short-message="message.content.length < 100"
+      :tts-icon="ttsPlayer.playing.value ? 'Ⅱ' : '▶'"
+      :tts-text="ttsPlayer.playing.value ? '暂停' : '播放'"
+      @toggle-collapse="toggleMessageCollapse(message)"
+      @copy="copyMessageContent(message)"
+      @change-direction="changeDirection"
+      @not-like-me="notLikeMe"
+      @continue="continueInChat"

+    />
+    <view v-else class="chat-bubble user">
+      <text>{{ message.content }}</text>
+      <text class="bubble-time">{{ message.time }}</text>
+    </view>
+  </view>
+</view>
+```
+
+- [ ] **Step 4: 提交使用组件**
+
+```bash
+cd "G:/IdeaProjects/emotion-museun"
+git add mini-program/src/pages/main/ScriptView.vue
+git commit -m "feat: ScriptView 复用 MessageCard 组件
+
+- story-card 使用 MessageCard
+- result-chat-list 中的 assistant 消息按内容长度自动切换短消息/完整卡片模式"
+```
+
+---
+
+### Task 3: 迁移并清理样式
+
+**Files:**
+- Modify: `mini-program/src/pages/main/ScriptView.vue`
+
+- [ ] **Step 1: 从 ScriptView.vue 中删除已迁移到 MessageCard 的样式**
+
+删除以下 CSS 类（从 `<style scoped>` 中移除）：
+- `.story-card`、`.story-card.collapsed`
+- `.story-head`、`.story-head-actions`、`.story-title-wrap`
+- `.story-title`、`.tag-row`、`.tag`
+- `.collapse-icon`、`.copy-card-btn`、`.collapse-row`
+- `.collapse-chevron`、`.story-body`、`.story-body-scroll`
+- `.result-actions`、`.action-btn`
+- `.message-actions`（上一轮临时添加的，不再使用）
+- `.message-toggle`（不再使用）
+
+保留 `ScriptView.vue` 中仍然需要的样式，如：
+- `.chat-bubble.user`
+- `.bubble-time`
+- `.result-chat-list`
+- `.thinking-dots`
+- 页面整体布局相关样式
+
+- [ ] **Step 2: 验证样式清理后无遗漏**
+
+```bash
+cd "G:/IdeaProjects/emotion-museun/mini-program"
+npm run build:h5 2>&1 | tail -20
+```
+
+预期输出：`DONE  Build complete.`
+
+- [ ] **Step 3: 提交样式清理**
+
+```bash
+cd "G:/IdeaProjects/emotion-museun"
+git add mini-program/src/pages/main/ScriptView.vue
+git commit -m "refactor: 迁移 story-card 相关样式到 MessageCard
+
+删除 ScriptView.vue 中已迁移到 MessageCard 的样式类"
+```
+
+---
+
+### Task 4: 最终验证
+
+**Files:**
+- 无需修改文件，仅做验证
+
+- [ ] **Step 1: 构建验证**
+
+```bash
+cd "G:/IdeaProjects/emotion-museun/mini-program"
+npm run build:h5 2>&1 | tail -20
+```
+
+预期输出：`DONE  Build complete.`
+
+- [ ] **Step 2: 功能验证（在 H5 浏览器中）**
+
+启动 H5 开发服务器并验证：
+
+```bash
+cd "G:/IdeaProjects/emotion-museun/mini-program"
+npm run dev:h5
+```
+
+打开浏览器访问显示的端口（默认 `http://localhost:5173`），执行以下验证：
+
+1. **第一次生成故事**：确认 story-card 样式、标题、标签、展开/收起、复制、功能按钮组均正常
+2. **重新生成（生成 script 类型长消息）**：
+   - 内容 ≥ 100 字：显示与 story-card 完全一致的卡片样式
+   - 内容 < 100 字：显示简洁气泡，无任何功能按钮
+3. **普通聊天 assistant 消息**：
+   - 内容 ≥ 100 字：显示完整卡片
+   - 内容 < 100 字：显示简洁气泡
+4. **用户消息**：保持原有 `.chat-bubble.user` 样式不变
+5. **控制台**：确认无 Vue 警告和 JavaScript 错误
+
+- [ ] **Step 3: 提交验证结果（如有修复）**
+
+如果在验证中修复了问题，提交：
+
+```bash
+git add mini-program/src/components/MessageCard.vue mini-program/src/pages/main/ScriptView.vue
+git commit -m "fix: 修复 MessageCard 组件验证中发现的问题
+
+[描述具体修复内容]"
+```
+
+如果验证全部通过，无需额外提交。
+
+---
+
+## 自审检查
+
+- **Spec 覆盖：**
+  - ✅ 创建 MessageCard.vue 组件 → Task 1
+  - ✅ ScriptView.vue 复用组件 → Task 2
+  - ✅ 100 字阈值判断 → Task 2 (`:is-short-message="message.content.length < 100"`)
