blog-image-embedder

读取经过润色的中文博客 markdown，解析标题与各章节，按统一风格生成头图与逐节图片提示词，在文中插入 [image:x] 占位符，并将插图版 markdown 保存到输出目录，最终返回文件路径、提示词数组与图片路径数组。适用于 blog-polish-zhcn 之后的配图环节。

Blog Image Embedder

Analyzes polished zh-CN markdown, generates consistent image prompts (hero + 1 per section), embeds [image:x] placeholders, saves illustrated version.

When to Use

Use after blog-polish-zhcn completes. Input is polishedPath from first skill. Triggers: "add images to my polished blog", "generate image prompts for sections".

Defaults

style: clean flat vector illustration, minimal isometric, software-engineering diagram vibe
background: default: white background with subtle grid
aspectRatioHero: 16:9 horizontal
aspectRatioSection: 16:9

Workflow Summary

Read polished markdown from input.polishedPath
Parse structure: Extract title + ## section headings (expect 3-4 sections)
Generate prompts:
- Hero: [Hero of {title}]: {topic summary}, {style}, {background}, 16:9
- Section N: [Section {N} of {title}]: {section summary}, {style}, {background}, 16:9
Embed placeholders: Insert \n\n[image:0]\n\n after title, \n\n[image:1]\n\n after first section, etc.
Save: ${outputDir}/${ts}-illustrated.md
Return: { illustratedPath, imagePrompts: [...], imagePaths: [...] }

Output Format

{
  "illustratedPath": "/home/jeff/.openclaw/workspace/contentPolished/2603142145-illustrated.md",
  "imagePrompts": ["Hero prompt...", "Section 1 prompt...", "Section 2 prompt..."],
  "imagePaths": ["2603142145-main.png", "2603142145-section1.png", "2603142145-section2.png"]
