+# AI Test Output Rendering Fix 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:** Make AI endpoint tests stream parsed正文 and render Markdown in the web-admin test dialogs.
+
+**Architecture:** Normalize provider stream deltas in backend adapters, add a frontend SSE/display fallback, and replace raw `<pre>` output blocks with a reusable Markdown preview. Keep request shapes and existing AI runtime APIs unchanged.
+
+**Tech Stack:** Spring Boot, Fastjson2, Vue 3, Element Plus, markdown-it.
+
+---
+
+### Task 1: Backend Stream Text Normalization
+
+**Files:**
+- Modify: `backend-single/src/main/java/com/emotion/service/ai/CozeProviderAdapter.java`
+- Modify: `backend-single/src/main/java/com/emotion/service/ai/DifyProviderAdapter.java`
+
+- [x] Add a private helper that parses JSON string wrappers and returns `output`, `answer`, `content`, `text`, `result`, `data.*`, or `outputs.*`.
+- [x] Call the helper before returning every extracted delta string.
+- [x] Keep non-JSON Markdown/plain text unchanged.
+
+### Task 2: Frontend Stream Parsing Fallback
+
+**Files:**
+- Modify: `web-admin/src/api/aiconfig.ts`
+
+- [x] Add a `normalizeAiText` helper mirroring backend wrapper extraction.
+- [x] Apply it before appending `delta.content` in `fetchSseStream`.
+- [x] Preserve the current callback signature.
+
+### Task 3: Markdown Preview Component
+
+**Files:**
+- Modify: `web-admin/package.json`
+- Modify: `web-admin/package-lock.json`
+- Create: `web-admin/src/components/MarkdownPreview.vue`
+
+- [x] Add `markdown-it` and its TypeScript types.
+- [x] Create a scoped Markdown renderer with safe defaults (`html: false`, `breaks: true`, `linkify: true`).
+- [x] Style headings, paragraphs, lists, code blocks, tables, and blockquotes for the existing dark admin theme.
+
+### Task 4: Test Dialog Output UX
+
+**Files:**
+- Modify: `web-admin/src/views/aiconfig/AiRoutingList.vue`
+
+- [x] Import and use `MarkdownPreview`.
+- [x] Replace raw test `<pre>` blocks with scrollable output panels.
+- [x] Parse non-stream and stream result output before display.
+- [x] Auto-scroll output panels when stream text updates.
+
+### Task 5: Verification
+
+**Commands:**
+- `cd web-admin && npm run build`
+- `cd backend-single && mvn test`
+- `git diff --check`
+
+- [x] Build passes.
+- [x] Backend tests pass.
+- [x] Diff check has no new whitespace errors beyond existing line-ending warnings.

+# AI 测试输出渲染修复设计
+
+## 目标
+
+后台管理的 AI 配置测试弹窗需要像真实用户端一样展示流式结果：逐步显示正文、支持滚动、Markdown 格式化展示，并避免把 Coze/Dify 的原始 JSON 包装直接丢到结果区。
+
+## 范围
+
+- 后端适配器在流式事件解析阶段提取真正正文。
+- web-admin 在 SSE 客户端和测试弹窗展示层做兜底解析。
+- web-admin 新增 Markdown 预览组件，结果区固定高度并支持滚动。
+- 不改变现有 AI 配置、场景绑定、接口测试请求参数和业务调用入口。
+
+## 设计
+
+### 后端正文规范化
+
+Coze 和 Dify 适配器在 `extract*Delta` 返回前先调用统一的文本解包逻辑。如果文本是 JSON 字符串，并且包含 `output`、`answer`、`content`、`text`、`result` 或嵌套 `data/outputs` 字段，就递归提取第一个可用正文。普通 Markdown、纯文本和非 JSON 内容保持原样。
+
+### 前端流式兜底
+
+`web-admin/src/api/aiconfig.ts` 在拼接 `delta.content` 前做同样的轻量解析，避免历史缓存、异常 provider 或非标准事件再次透出包装 JSON。解析失败时保持原文本，保证兼容。
+
+### 测试弹窗展示
+
+新增 `MarkdownPreview` 组件，用 `markdown-it` 渲染 Markdown。场景测试和接口工作流测试的非流式、流式结果都通过该组件展示；失败结果按纯文本展示。输出区域使用固定最大高度和 `overflow-y: auto`，流式更新时自动滚动到底部。
+
+## 验证
+
+- `web-admin` 执行依赖安装与生产构建。
+- 后端执行 Maven 测试或打包。
+- 关键检查：Coze 返回 `{"output":"### 标题"}` 时，弹窗展示 `### 标题` 的 Markdown 渲染结果，不展示原始 JSON。
