+# Phase 5: HTML Assembly
+
+使用 `universal-executor` 子 Agent 生成最终 HTML，避免主 Agent 内存溢出。
+
+## 核心原则
+
+**主 Agent 负责编排，子 Agent 负责繁重计算。**
+
+## 执行流程
+
+```javascript
+const config = JSON.parse(Read(`${workDir}/manual-config.json`));
+
+// 委托给 universal-executor 执行 HTML 组装
+const result = Task({
+  subagent_type: 'universal-executor',
+  run_in_background: false,
+  prompt: buildAssemblyPrompt(config, workDir)
+});
+
+const buildResult = JSON.parse(result);
+```
+
+## Prompt 构建
+
+```javascript
+function buildAssemblyPrompt(config, workDir) {
+  return `
+[ROLE] HTML Assembler
+
+[TASK]
+生成 TiddlyWiki 风格的交互式 HTML 手册
+
+[INPUT]
+- 模板: .claude/skills/software-manual/templates/tiddlywiki-shell.html
+- CSS: .claude/skills/software-manual/templates/css/wiki-base.css, wiki-dark.css
+- 配置: ${workDir}/manual-config.json
+- 章节: ${workDir}/sections/section-*.md
+- 截图: ${workDir}/screenshots/
+
+[STEPS]
+1. 读取 HTML 模板和 CSS
+2. 逐个读取 section-*.md，转换为 HTML tiddlers
+3. 处理 <!-- SCREENSHOT: id="..." --> 标记，嵌入 Base64 图片
+4. 生成目录、搜索索引
+5. 组装最终 HTML，写入 ${workDir}/${config.software.name}-使用手册.html
+6. 生成构建报告 ${workDir}/build-report.json
+
+[HTML FEATURES]
+- 搜索: 全文检索 + 高亮
+- 折叠: 章节可展开/收起
+- 标签: 分类过滤
+- 主题: 亮/暗模式切换
+- 离线: 所有资源内嵌
+
+[RETURN JSON]
+{
+  "status": "completed",
+  "output_file": "${config.software.name}-使用手册.html",
+  "file_size": "<size>",
+  "sections_count": <n>,
+  "screenshots_embedded": <n>
+}
+`;
+}
+```
+
+## Agent 职责
+
+1. **读取模板** → HTML + CSS
+2. **转换章节** → Markdown → HTML tiddlers
+3. **嵌入截图** → Base64 编码
+4. **生成索引** → 搜索数据
+5. **组装输出** → 单文件 HTML
+
+## Markdown 转换规则
+
+Agent 内部实现：
+
+```
+# H1 → <h1>
+## H2 → <h2>
+### H3 → <h3>
+```code``` → <pre><code>
+**bold** → <strong>
+*italic* → <em>
+[text](url) → <a href>
+- item → <li>
+<!-- SCREENSHOT: id="xxx" --> → <figure><img src="data:..."></figure>
+```
+
+## Tiddler 结构
+
+```html
+<article class="tiddler" id="tiddler-{name}" data-tags="..." data-difficulty="...">
+  <header class="tiddler-header">
+    <h2><button class="collapse-toggle">▼</button> {title}</h2>
+    <div class="tiddler-meta">{badges}</div>
+  </header>
+  <div class="tiddler-content">{html}</div>
+</article>
+```
+
+## 输出
+
+- `{软件名}-使用手册.html` - 最终 HTML
+- `build-report.json` - 构建报告
+
+## 质量门禁
+
+- [ ] HTML 渲染正确
+- [ ] 搜索功能可用
+- [ ] 折叠/展开正常
+- [ ] 主题切换持久化
+- [ ] 截图显示正确
+- [ ] 文件大小 < 10MB
