+# 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.
