# 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.
