+# 产物系统参考文档
+
+> 调研 DeerFlow 和 Hermes Agent 的产物/输出面板实现，为 ZCLAW 产物系统重构提供参考。
+> 分析日期：2026-04-24
+
+---
+
+## 一、DeerFlow 产物系统
+
+DeerFlow 有完整的全栈产物管道，是主要参考对象。
+
+### 1.1 端到端数据流
+
+```
+Agent tool call (write_file / str_replace / present_files)
+    ↓
+Backend: ThreadState.artifacts (LangGraph annotated list, merge_artifacts reducer 去重)
+    ↓ 文件写入: {base_dir}/threads/{thread_id}/user-data/outputs/
+    ↓ 虚拟路径: /mnt/user-data/outputs/filename.ext
+    ↓
+Backend API: GET /api/threads/{thread_id}/artifacts/{virtual_path}
+    ↓ MIME 检测 / .skill ZIP 解压 / download vs inline
+    ↓
+Frontend: thread.values.artifacts (string[]) → ArtifactsProvider context
+    ↓
+ChatBox (ResizablePanelGroup) → chat(60%) | artifact panel(40%)
+    ↓
+ArtifactFileDetail → CodeMirror(代码) / Streamdown(Markdown) / iframe(HTML)
+```
+
+### 1.2 关键文件
+
+#### 前端核心
+
+| 文件 | 职责 |
+|------|------|
+| `frontend/src/core/artifacts/utils.ts` | URL 构建、产物列表提取、路径解析 |
+| `frontend/src/core/artifacts/loader.ts` | 从后端 API 获取产物文本；从 tool call args 直接提取内容 |
+| `frontend/src/core/artifacts/hooks.ts` | TanStack React Query hook，5 分钟缓存 |
+| `frontend/src/components/workspace/artifacts/context.tsx` | ArtifactsProvider + useArtifacts() — 管理列表、选中、开关、自动选中 |
+| `frontend/src/components/workspace/artifacts/artifact-file-detail.tsx` | 产物详情视图：头部(文件选择器+code/preview切换) + CodeEditor/Preview |
+| `frontend/src/components/workspace/artifacts/artifact-file-list.tsx` | 卡片式列表视图，每个卡片含图标/名称/扩展名/下载/安装按钮 |
+| `frontend/src/components/workspace/artifacts/artifact-trigger.tsx` | 头部触发按钮，仅在产物存在时显示 |
+
+#### 前端渲染
+
+| 文件 | 职责 |
+|------|------|
+| `frontend/src/components/workspace/code-editor.tsx` | CodeMirror 只读编辑器，支持 CSS/HTML/JS/JSON/MD/Python 语法高亮 |
+| `frontend/src/components/ai-elements/code-block.tsx` | Shiki 语法高亮代码块，双主题(light/dark) |
+| `frontend/src/components/ai-elements/web-preview.tsx` | iframe 网页预览，含地址栏和导航按钮 |
+| `frontend/src/components/workspace/messages/markdown-content.tsx` | Streamdown 渲染 Markdown (GFM + Math + Raw HTML + KaTeX) |
+| `frontend/src/core/utils/files.tsx` | 140+ 扩展名→语言映射，文件图标/类型判断 |
+
+#### 后端
+
+| 文件 | 职责 |
+|------|------|
+| `backend/.../thread_state.py` | ThreadState.artifacts 列表 + merge_artifacts 去重 reducer |
+| `backend/.../present_file_tool.py` | present_files 工具 — 标准化路径，返回 Command(update) |
+| `backend/.../paths.py` | 路径管理：threads/{id}/user-data/{workspace,uploads,outputs} |
+| `backend/app/gateway/routers/artifacts.py` | FastAPI 路由：GET 产物文件，MIME 检测，安全处理 |
+
+### 1.3 支持的内容类型
+
+| 类型 | 渲染方式 |
+|------|----------|
+| 代码文件 (140+ 扩展名) | CodeMirror 只读 + 语法高亮 |
+| Markdown (.md) | Streamdown (GFM + Math + KaTeX + Raw HTML) |
+| HTML (.html/.htm) | 沙箱 `
