HTML PPT 阅读器 Skill

⚠️ 出图前必走 · ppt 出图法 V2 7 步

重要：本 skill 只负责"把已有图打包成 HTML"。生图前必须走ppt 出图法 V2 7 步：

1. fetch 完整仓库内容（README + 子目录 + examples 并行）
2. reset todo（明确节奏）
3. 整理 "N 张图主题+核心一句话" 清单（每张 1 行）
4. 单张 prompt ≤ 60 行（不堆字体铁律）
5. 出 P1 hook → 渲染核对清单（10+ 项）→ 走批量
6. 接受 AI 主动加的细节和布局调整
7. 沉淀到 case 文档

ppt 出图法 V2 完整方法论见 ~/.mavis/knowledge/knowhub/domains/visual-creation/methodology/ppt-out-image-method.md。

反例（2026-07-02 how-to-agent-ppt）：因为没走 V2 7 步 → PPT 图字体幼稚、布局不丰富、AI 调整被否定 → 用户反馈"前天的好多了"。

正例（2026-06-30 ai-training-ppt）：走了 V2 7 步 → 60 行 prompt + 接受 AI 加细节 + 渲染核对 → 8 张图一气呵成。

跳过 V2 7 步直接调本 skill = 极大概率翻车。
