English Speaking 班级答题面板 实施计划

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: 在 PPT 学生端老师视角点击「答案」按钮后,展示英语口语 (toolType=77) 的班级答题情况面板,支持事件驱动的实时学生状态更新与混合模式 AI 总结。

Architecture: 复用 PPT 现有 y-websocket 通道,加一种新消息类型 speaking_session_updated,事件驱动 list refetch(1s 防抖)。后端新增 2 个端点(list / summary),summary 端点使用 OneHub LLM + 60s 内存缓存,失败退化为规则版 bullets。前端 Student/index.vue 4 处外科手术改动,英语口语预览组件通过 provide/inject 透传状态变化。

Tech Stack: 后端 FastAPI + SQLAlchemy 2 async + AsyncOpenAI,前端 Vue 3 setup script + Pinia + scoped SCSS。后端 pytest 用 in-memory SQLite + httpx ASGITransport。前端无单元测试设施,改动后手动冒烟。

Spec: docs/superpowers/specs/2026-05-06-english-speaking-class-answer-panel-design.md

Repo paths:

  • 前端 (本仓库 PPT): /Users/buoy/Development/gitrepo/PPT
  • 后端 (英语口语 API): /Users/buoy/Development/gitrepo/cococlass-english-speaking-api

Backend test command: uv run pytest -xvs <test_path> (在 cococlass-english-speaking-api 目录下)


Phase A — 后端 list 端点

Task 1: 服务方法 list_sessions_by_config

                if isinstance(dims, dict):
                    dimensions = dims
                hl = s.overall_report.get("highlights")
                if isinstance(hl, list):
                    top_highlights = [x for x in hl[:2] if isinstance(x, str)]
                sg = s.overall_report.get("suggestions")
                if isinstance(sg, list):
                    top_improvements = [x for x in sg[:2] if isinstance(x, str)]
            summaries.append({
                "userId": s.user_id,
                "sessionId": s.uuid,
                "status": s.status,
                "overallStatus": s.overall_status,
                "currentRound": s.current_round,
                "totalRounds": s.total_rounds,
                "overallScore": score,
                "dimensions": dimensions,
                "topHighlights": top_highlights,
                "topImprovements": top_improvements,
                "createdAt": _isoformat_utc(s.created_at) if s.created_at else None,
                "completedAt": _isoformat_utc(s.completed_at) if s.completed_at else None,
            })
  • Step 4: 同步前端 service.ts 类型(注释,实际改在 Phase C)

不改代码,只在心里记住:ClassSessionSummary 前端类型要加 dimensions / topHighlights / topImprovements(后续 Task 8 会补上)。

  • Step 5: 改 _build_llm_per_student 用上这些字段

在 dialogue_service.py 中替换:

    @staticmethod
    def _build_llm_per_student(summaries: list[dict]) -> list[dict]:
        out = []
        for s in summaries:
            if s.get("status") != "completed":
                continue
            out.append({
                "score": s.get("overallScore"),
                "dimensions": s.get("dimensions") or {},
                "topHighlights": s.get("topHighlights") or [],
                "topImprovements": s.get("topImprovements") or [],
            })
        return out
  • Step 6: 运行测试
uv run pytest tests/service/test_list_sessions_by_config.py tests/service/test_generate_class_summary.py -xvs

Expected: 全部 passed

  • Step 7: 提交
git add app/service/speaking/dialogue_service.py tests/service/test_list_sessions_by_config.py
git commit -m "feat(speaking): include dimensions/highlights in list summary for LLM input"

Task 7: HTTP 端点 POST /sessions/by-config/summary

Files:

  • Modify: cococlass-english-speaking-api/app/api/dialogue.py (在 list endpoint 之后追加)
  • Test: cococlass-english-speaking-api/tests/api/test_dialogue_class_summary.py (新文件)

  • [ ] Step 1: 写失败的 API 测试

  • Step 2: 运行测试,确认失败
uv run pytest tests/api/test_dialogue_class_summary.py -xvs

Expected: 6 failures (404)

  • Step 3: 实现端点

在 app/api/dialogue.py 顶部 import 区追加(若 BaseModel 已 import 则跳过):

from pydantic import BaseModel

在 list_sessions_by_config 端点之后追加:

class ClassSummaryRequest(BaseModel):

    userIds: list[str]
    locale: str = "zh"


@router.post("/sessions/by-config/summary")
async def class_summary(

  • Step 4: 运行测试
uv run pytest tests/api/test_dialogue_class_summary.py -xvs

git add app/api/dialogue.py tests/api/test_dialogue_class_summary.py
git commit -m "feat(speaking): add POST /sessions/by-config/summary endpoint"

后端阶段完成。 切换到 PPT 仓库继续。


Phase C — 前端 service 层 + 类型定义

Task 8: 扩展 services/speaking.ts

Files:

  • Modify: PPT/src/services/speaking.ts

  • [ ] Step 1: 添加类型 + 两个 fetch 函数

在 PPT/src/services/speaking.ts 文件末尾追加:

import { SPEAKING_DIALOGUE_API_BASE_URL } from '@/views/Editor/EnglishSpeaking/services/speakingApiConfig'

const DIALOGUE_BASE = SPEAKING_DIALOGUE_API_BASE_URL

export interface ClassSessionSummary {
  userId: string
  sessionId: string
  status: 'active' | 'completed' | 'abandoned'
  overallStatus: 'ready' | 'generating' | 'failed' | null
  currentRound: number
  totalRounds: number
  overallScore: number | null
  dimensions: Record<string, number>
  topHighlights: string[]
  topImprovements: string[]
  createdAt: string | null
  completedAt: string | null
}

export interface ListSessionsByConfigResponse {
  summaries: ClassSessionSummary[]
}

export async function listSpeakingSessionsByConfig(
  configId: string,
  userIds: string[],
): Promise<ListSessionsByConfigResponse> {
  const params = new URLSearchParams({ configId, userIds: userIds.join(',') })
  const res = await fetch(`${DIALOGUE_BASE}/sessions/by-config?${params}`, {
    method: 'GET',
    credentials: 'include',
  })
  if (!res.ok) throw new Error(`listSpeakingSessionsByConfig failed: ${res.status}`)
  return res.json()
}

export interface ClassSummaryResponse {
  bullets: [string, string, string]
  generatedAt: string
  fromCache: boolean
  llmStatus: 'ok' | 'fallback'
}

export async function generateClassSummary(
  configId: string,
  userIds: string[],
  locale: 'zh' | 'en' | 'hk',
): Promise<ClassSummaryResponse> {
  const res = await fetch(`${DIALOGUE_BASE}/sessions/by-config/summary`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    credentials: 'include',
    body: JSON.stringify({ configId, userIds, locale }),
  })
  if (!res.ok) throw new Error(`generateClassSummary failed: ${res.status}`)
  return res.json()
}
  • Step 2: TypeScript 检查
cd /Users/buoy/Development/gitrepo/PPT
npx vue-tsc --noEmit 2>&1 | head -30

Expected: 无新增错误(可能有项目历史 warning,只关注 services/speaking.ts 行)

  • Step 3: 提交
git add src/services/speaking.ts
git commit -m "feat(speaking): add service helpers for class list/summary endpoints"

Phase D — 前端 i18n

Task 9: 在 cn.json / en.json / hk.json 添加 ssSpk* keys

Files:

  • Modify: PPT/src/views/lang/cn.json
  • Modify: PPT/src/views/lang/en.json
  • Modify: PPT/src/views/lang/hk.json

  • [ ] Step 1: 找到 cn.json 中可以追加 ssSpk* 的位置

grep -n "ssRefresh\|}" /Users/buoy/Development/gitrepo/PPT/src/views/lang/cn.json | tail -3
  • Step 2: 在 cn.json 倒数第二行(最后 } 前)追加(注意前一行末尾加 ,)

向 cn.json 添加(根据现有 ss* keys 风格):

  "ssSpkJustNow": "刚刚生成",
  "ssSpkSecondsAgoTpl": "{n} 秒前生成",
  "ssSpkMinutesAgoTpl": "{n} 分钟前生成"

注意: 含 {xxx} 占位符的 key 全部加 Tpl 后缀,以提示开发者需要做模板替换。

  • Step 3: 在 en.json 同位置追加英文版本
  "ssSpkFilterAll": "All",
  "ssSpkFilterSubmitted": "Done",
  "ssSpkFilterUnsubmitted": "In Progress",
  "ssSpkFilterNotStarted": "Not Started",

  • Step 4: 在 hk.json 追加繁体版本(完整列表与 cn.json 等价但用繁体)
  "ssSpkFilterAll": "全部",
  "ssSpkFilterSubmitted": "已完成",
  "ssSpkFilterUnsubmitted": "進行中",
  "ssSpkFilterNotStarted": "未開始",
  "ssSpkSortTimeAsc": "時間正序",

node -e "JSON.parse(require('fs').readFileSync('src/views/lang/en.json'))"
node -e "JSON.parse(require('fs').readFileSync('src/views/lang/hk.json'))"

Expected: 三条命令均无输出(成功)

  • Step 6: 提交
git add src/views/lang/cn.json src/views/lang/en.json src/views/lang/hk.json
git commit -m "feat(speaking): add ssSpk* i18n keys for class answer panel"

Phase E — 前端 composable + 类型

Task 10: 类型文件 types.ts

Files:

  • Create: PPT/src/views/Student/components/SpeakingClassPanel/types.ts

  • [ ] Step 1: 创建目录与类型文件

mkdir -p /Users/buoy/Development/gitrepo/PPT/src/views/Student/components/SpeakingClassPanel

创建 PPT/src/views/Student/components/SpeakingClassPanel/types.ts:

  • Step 2: TypeScript 检查
npx vue-tsc --noEmit 2>&1 | grep -E "SpeakingClassPanel" | head -10

Expected: 无输出

  • Step 3: 提交
git add src/views/Student/components/SpeakingClassPanel/index.vue
git commit -m "feat(speaking): add SpeakingClassPanel main panel"

Phase H — 接入 Student/index.vue

Task 18: 引入组件 + 计算 toolType / configId

Files:

  • Modify: PPT/src/views/Student/index.vue

  • [ ] Step 1: 找到 import 区

grep -n "import choiceQuestionDetailDialog\|import.*from './components" /Users/buoy/Development/gitrepo/PPT/src/views/Student/index.vue | head -10
  • Step 2: 在 choiceQuestionDetailDialog 的 import 之后追加

找到 import choiceQuestionDetailDialog from './components/choiceQuestionDetailDialog.vue' 那一行,之后追加:

import SpeakingClassPanel from './components/SpeakingClassPanel/index.vue'
  • Step 3: 找到 currentSlideHasIframe computed
grep -n "const currentSlideHasIframe\|currentSlideHasBilibiliVideo" /Users/buoy/Development/gitrepo/PPT/src/views/Student/index.vue | head -5
  • Step 4: 在 currentSlideHasIframe 之后添加 currentSlideToolType / currentSlideConfigId

找到 currentSlideHasIframe 的 computed 块(约在 line 977 附近),在它之后、currentSlideHasBilibiliVideo 之前插入:

const currentSlideToolType = computed(() => {
  const frame = elementList.value.find(element => element.type === ElementTypes.FRAME)
  return Number((frame as any)?.toolType) || 0
})
const currentSlideConfigId = computed(() => {
  if (currentSlideToolType.value !== 77) return ''
  const frame = elementList.value.find(element => element.type === ElementTypes.FRAME)
  return (frame as any)?.url || ''
})
  • Step 5: 提交(增量,先不接模板)
cd /Users/buoy/Development/gitrepo/PPT
git add src/views/Student/index.vue
git commit -m "feat(speaking): import SpeakingClassPanel and add toolType computed"

Task 19: 模板分支 + provide notify

Files:

  • Modify: PPT/src/views/Student/index.vue

  • [ ] Step 1: 找到 choiceQuestionDetailDialog 模板

grep -n "choiceQuestionDetailDialog v-if" /Users/buoy/Development/gitrepo/PPT/src/views/Student/index.vue
  • Step 2: 改 v-if 为对 toolType 的限定 + 追加 v-else-if 分支

将这一行(应在 line ~109 附近):

<choiceQuestionDetailDialog v-if="choiceQuestionDetailDialogOpenList.includes(slideIndex)" :workId="workId"  :userId="props.userid" :courseDetail="courseDetail" :workArray="workArray" @changeWorkIndex="changeWorkIndex" v-model:visible="choiceQuestionDetailDialogOpenList" :showData="answerTheResultRef" :slideIndex="slideIndex" :workIndex="0" :style="{ width: isFullscreen ? '100%' : slideWidth2 * canvasScale + 'px', height: isFullscreen ? '100%' : slideHeight2 * canvasScale + 'px', margin: '0 auto' }" :slideWidth="isFullscreen ? slideWidth * canvasScale : slideWidth2 * canvasScale" :slideHeight="isFullscreen ? slideHeight * canvasScale : slideHeight2 * canvasScale"/>

替换成:

<choiceQuestionDetailDialog v-if="choiceQuestionDetailDialogOpenList.includes(slideIndex) && currentSlideToolType !== 77" :workId="workId"  :userId="props.userid" :courseDetail="courseDetail" :workArray="workArray" @changeWorkIndex="changeWorkIndex" v-model:visible="choiceQuestionDetailDialogOpenList" :showData="answerTheResultRef" :slideIndex="slideIndex" :workIndex="0" :style="{ width: isFullscreen ? '100%' : slideWidth2 * canvasScale + 'px', height: isFullscreen ? '100%' : slideHeight2 * canvasScale + 'px', margin: '0 auto' }" :slideWidth="isFullscreen ? slideWidth * canvasScale : slideWidth2 * canvasScale" :slideHeight="isFullscreen ? slideHeight * canvasScale : slideHeight2 * canvasScale"/>
<SpeakingClassPanel
  v-else-if="choiceQuestionDetailDialogOpenList.includes(slideIndex) && currentSlideToolType === 77"
  ref="speakingPanelRef"
  :configId="currentSlideConfigId"
  :slideIndex="slideIndex"
  :studentArray="studentArray"
  :courseId="props.courseid"
  :slideWidth="isFullscreen ? slideWidth * canvasScale : slideWidth2 * canvasScale"
  :slideHeight="isFullscreen ? slideHeight * canvasScale : slideHeight2 * canvasScale"
  :style="{ margin: '0 auto' }"
/>
  • Step 3: 找到 setup script 中可以加 ref + provide 的位置
grep -n "import { provide\|const speakingPanelRef\|const choiceQuestionDetailDialogOpenList" /Users/buoy/Development/gitrepo/PPT/src/views/Student/index.vue | head -5
  • Step 4: 确保 vue 的 provide 已被 import

如果 import { provide 没有出现,在文件顶部找 import { 起手的 vue import 那一行,把 provide 加上。

grep -n "^import.*from 'vue'" /Users/buoy/Development/gitrepo/PPT/src/views/Student/index.vue | head -3

修改 vue import 行使其包含 provide(具体合并写法看现有 import):

import { ..., provide } from 'vue'
  • Step 5: 在 setup 中添加 ref + provide

在 const choiceQuestionDetailDialogOpenList = ref<number[]>([]) 之后(约 line 549),添加:

const speakingPanelRef = ref<InstanceType<typeof SpeakingClassPanel> | null>(null)

provide('notifySpeakingProgress', (status: 'active' | 'completed', payload: { configId: string; sessionId: string }) => {
  if (props.type !== '2') return  // 只有学生客户端发广播
  sendMessage({
    type: 'speaking_session_updated',
    courseid: props.courseid,
    slideIndex: slideIndex.value,
    userid: props.userid,
    status,
    ...payload,
  })
})
  • Step 6: TypeScript 检查
npx vue-tsc --noEmit 2>&1 | grep -E "Student/index\.vue" | head -10

Expected: 无新增错误

  • Step 7: 提交
git add src/views/Student/index.vue
git commit -m "feat(speaking): branch render to SpeakingClassPanel for toolType=77"

Task 20: handleSocketMessage 加分支

Files:

  • Modify: PPT/src/views/Student/index.vue

  • [ ] Step 1: 找到 homework_submitted 处理位置

grep -n "homework_submitted.*msgObj.courseid" /Users/buoy/Development/gitrepo/PPT/src/views/Student/index.vue

应在 line ~3287 附近。

  • Step 2: 在 homework_submitted 处理块之后追加 speaking 分支

找到这一段(line ~3287-3295):

  // 处理作业提交消息 - 当有人提交作业时,重新获取作业数据
  if (props.type == '1' && msgObj.type === 'homework_submitted' && msgObj.courseid === props.courseid) {
    console.log('收到作业提交消息,重新获取作业数据')
    // 延迟一点时间,确保后端数据已更新
    setTimeout(() => {
      if (currentSlideHasIframe.value) {
        getWork(true) // 传入true表示是更新模式
      }
    }, 1000)
  }

在 } 之后直接追加:

  // 处理英语口语状态更新 - 学生开始/完成对话时,刷新班级答题面板
  if (props.type == '1' && msgObj.type === 'speaking_session_updated' && msgObj.courseid === props.courseid) {
    console.log('收到英语口语状态更新,触发面板刷新')
    speakingPanelRef.value?.scheduleRefetch?.()
  }
  • Step 3: TypeScript 检查
npx vue-tsc --noEmit 2>&1 | grep -E "Student/index\.vue" | head -10

Expected: 无新增错误

  • Step 4: 提交
git add src/views/Student/index.vue
git commit -m "feat(speaking): handle speaking_session_updated socket message"

Phase I — 学生端广播

Task 21: TopicDiscussionPreview.vue 接入 inject + 广播

Files:

  • Modify: PPT/src/views/Editor/EnglishSpeaking/preview/TopicDiscussionPreview.vue

  • [ ] Step 1: 找到 import 区

grep -n "^import\|setup>" /Users/buoy/Development/gitrepo/PPT/src/views/Editor/EnglishSpeaking/preview/TopicDiscussionPreview.vue | head -10
  • Step 2: 加 inject + 类型声明

在 <script lang="ts" setup> 顶部 import 区追加:

import { inject } from 'vue'

type SpeakingNotify = (
  status: 'active' | 'completed',
  payload: { configId: string; sessionId: string },
) => void
const notifySpeakingProgress = inject<SpeakingNotify>('notifySpeakingProgress', () => {})
  • Step 3: 找到 startDialogue 末尾
grep -n "dialogueState.value = 'chatting'\|sessionCreating.value = false" /Users/buoy/Development/gitrepo/PPT/src/views/Editor/EnglishSpeaking/preview/TopicDiscussionPreview.vue | head -10

应能找到 2~3 处 dialogueState.value = 'chatting'。

  • Step 4: 在每处 dialogueState='chatting' 之后追加 notify

对每个 dialogueState.value = 'chatting' 行,紧跟其后追加:

    notifySpeakingProgress('active', {
      configId: props.configId || '',
      sessionId: preparedSession.value?.sessionId || '',
    })

注意上下文:

  • 在 startDialogue 函数内的 dialogueState.value = 'chatting' 之后追加
  • 在 loadLatestStudentSession 中拿到 active session 后置 dialogueState.value = 'chatting' 之后也追加

  • [ ] Step 5: 找到 handleDialogueComplete

grep -n "function handleDialogueComplete\|dialogueState.value = 'completed'" /Users/buoy/Development/gitrepo/PPT/src/views/Editor/EnglishSpeaking/preview/TopicDiscussionPreview.vue
  • Step 6: 在 dialogueState.value = 'completed' 之后追加 notify

在 handleDialogueComplete 函数内的 dialogueState.value = 'completed' 之后追加:

  if (preparedSession.value?.sessionId) {
    notifySpeakingProgress('completed', {
      configId: props.configId || '',
      sessionId: preparedSession.value.sessionId,
    })
  }
  • Step 7: TypeScript 检查
npx vue-tsc --noEmit 2>&1 | grep -E "TopicDiscussionPreview" | head -10

Expected: 无新增错误

  • Step 8: 提交
git add src/views/Editor/EnglishSpeaking/preview/TopicDiscussionPreview.vue
git commit -m "feat(speaking): broadcast session_updated on chat start/complete"

Phase J — 联调与冒烟

Task 22: 启动开发环境并跑冒烟用例

Files: 无新文件

  • Step 1: 启动后端
cd /Users/buoy/Development/gitrepo/cococlass-english-speaking-api
uv run uvicorn app.main:app --reload --port 8001

放到后台运行,观察 startup log 无错误。

  • Step 2: 启动前端 dev server
cd /Users/buoy/Development/gitrepo/PPT
npm run dev

放后台,等 vite 输出 Local: URL。

  • [ ] Step 3: 冒烟用例 1 — 老师打开答案 Tab

  • 用老师账号进入含 toolType=77 slide 的课堂

  • 点击「答案」按钮

  • 断言: SpeakingClassPanel 渲染,班级网格出现学生卡片;AI 总结显示 bullet 1 + 后两条骨架/Fallback 文案

  • [ ] Step 4: 冒烟用例 2 — 学生开始对话 → 老师面板更新

  • 用学生 A 在另一浏览器开始对话

  • 断言: 老师面板 ≤2 秒内,A 的卡片从 「未开始」 → 「进行中」(amber 边 + 脉冲点)

  • [ ] Step 5: 冒烟用例 3 — 学生完成对话 → 老师面板更新 + 分数

  • 学生 A 完成对话

  • 断言: 老师面板 A 的卡片变 「已完成」 (黄边 + ✓);bullet 1 数字更新;若 overall_report 已生成,卡片可显示分数

  • [ ] Step 6: 冒烟用例 4 — 风暴防抖

  • 模拟 3 名学生 1 秒内连续完成

  • 断言: network 面板 list 端点 1 秒内最多调 1 次,summary 端点不被触发

  • [ ] Step 7: 冒烟用例 5 — 点击已完成学生 → modal 显示报告

  • 老师点击 ✓ 学生卡片

  • 断言: modal 弹出,显示 OverallReport(分数/雷达/亮点/建议) + DetailedReport

  • [ ] Step 8: 冒烟用例 6 — 点击进行中学生 → modal 显示对话

  • 老师点击 amber 学生卡片

  • 断言: modal 弹出,标题写「的对话记录」 + 进行中 badge,只显示 DetailedReport

  • [ ] Step 9: 冒烟用例 7 — 点击未开始学生 → tip 弹窗

  • 老师点击灰底虚线学生卡片

  • 断言: 出现「该学生尚未开始练习」小弹窗,知道了 关闭

  • [ ] Step 10: 冒烟用例 8 — 切到非 77 的 slide → 走原路径(回归)

  • 切到含选择题的 slide,点 答案

  • 断言: 仍是 choiceQuestionDetailDialog 渲染(原行为)

  • [ ] Step 11: 冒烟用例 9 — Editor 预览不广播(回归)

  • 老师在编辑器中创建/编辑英语口语配置,触发预览

  • 断言: network 面板没有 speaking_session_updated 类型的 socket 消息

  • [ ] Step 12: 冒烟用例 10 — list 接口断网 → 错误条

  • DevTools network throttle 离线;在面板内点击 重试

  • 断言: 错误条显示「加载班级数据失败」 + 重试按钮可见

  • [ ] Step 13: 冒烟用例 11 — AI 总结骨架 + fade-in

  • 关闭面板再重开

  • 断言: bullet 1 立即可见;bullets 2/3 显示骨架 ~3 秒后 fade-in 真文案

  • [ ] Step 14: 冒烟用例 12 — 60s 内点刷新返回缓存

  • 进入面板等 LLM 完成,然后立即点 刷新

  • 断言: network 看到 fromCache: true,文案瞬出无骨架

  • [ ] Step 15: 冒烟用例 13 — 数据变化后刷新真调 LLM

  • 让一个学生完成 → 点 刷新

  • 断言: network 看到 fromCache: false,bullets 2/3 重新走 ~3 秒骨架

  • [ ] Step 16: 冒烟用例 14 — LLM 失败退化

  • 临时把后端 ONEHUB_API_KEY 改错,前端点 刷新

  • 断言: bullets 2/3 显示规则版本(平均分/行动建议),不弹错误,console 有日志

  • [ ] Step 17: 关闭后端 / dev server

# 切到运行后端的终端 Ctrl+C
# 切到 vite dev server 终端 Ctrl+C
  • Step 18: 如果所有冒烟用例通过,合入 master 前再跑一次后端全量测试
cd /Users/buoy/Development/gitrepo/cococlass-english-speaking-api
uv run pytest -q

Expected: 全部 passed
