+The skill is a structured workflow; the agent walks you through each step:
 
 1. **Clarify intent** — 6-question checklist: audience, duration, source material, images, theme, hard constraints
 2. **Copy template** — `assets/template.html` → project folder, update `<title>`, swap theme vars
 3. **Fill content** — pick from 10 layout skeletons, paste, edit copy (with class-name pre-flight + theme rhythm plan)

+## Codex Image Flow
+
+In Codex, after the first deck draft is ready, the agent can ask whether the user wants generated visuals. Once confirmed, choose an image type or style. Common types include:
+
+- Documentary photos: Fuji / Leica-like real-world scenes that add human texture
+- Infographics / flow diagrams / comparison charts / system maps: for concepts that cannot be explained well with photos
+- Screenshot redesigns / UI scenes: reshape raw screenshots into consistent slide-friendly ratios and visual density
+
+Generated images must follow two core rules:
+
+- Treat the image as an embedded asset, not a standalone slide: no footer, page bottom, title, page number, corner mark, signature, or decorative border
+- Match the slot ratio before generation: 16:9 / 16:10 for main visuals, 16:10 for UI scenes, fixed equal heights for image grids

+## Codex 配图能力
+
+在 Codex 环境中,完成 deck 初稿后可以主动询问用户是否需要生成配图。用户确认后,再选择图片类型或风格,常用类型包括:
+
+- 人文纪实照片:富士 / 徕卡感的真实场景,增加人文表现力
+- 信息图 / 流程图 / 对比图 / 系统关系图:用于解释无法用实拍照片说明的概念
+- 截图再设计 / UI 情景图:把原始截图统一成适合 PPT 的比例和视觉密度
+
+生成图片时要遵守两个关键规则:
+
+- 图片是 PPT 中的嵌入素材,不要自带页脚、页底、标题、角标、页码或装饰边框
+- 图片比例必须先匹配落位:主图常用 16:9 / 16:10,截图再设计常用 16:10,多图网格统一高度
