path/to/
├── article.md
└── imgs/
    ├── outline.md
    ├── prompts/
    │   ├── illustration-concept-a.md
    │   ├── illustration-concept-b.md
    │   └── ...
    ├── illustration-concept-a.png
    ├── illustration-concept-b.png
    └── ...
```

## Workflow

### Step 1: Analyze Content & Select Style

1. Read article content
2. If `--style` specified, use that style
3. Otherwise, scan for style signals and auto-select
4. Extract key information:
   - Main topic and themes
   - Core messages per section
   - Abstract concepts needing visualization

### Step 2: Identify Illustration Positions

**Three Purposes of Illustrations**:
1. **Information Supplement**: Help understand abstract concepts
2. **Concept Visualization**: Transform abstract ideas into concrete visuals
3. **Imagination Guidance**: Create atmosphere, enhance reading experience

**Content Suitable for Illustrations**:
- Abstract concepts needing visualization
- Processes/steps needing diagrams
- Comparisons needing visual representation
- Core arguments needing reinforcement
- Scenarios needing imagination guidance

**Illustration Count**:
- Consider at least 1 image per major section
- Prioritize core arguments and abstract concepts
- **Principle: More is better than fewer**

### Step 3: Generate Illustration Plan

```markdown
# Illustration Plan

**Article**: [article path]
**Style**: [selected style]
**Illustration Count**: N images

---

## Illustration 1

**Insert Position**: [section name] / [paragraph description]
**Purpose**: [why illustration needed here]
**Visual Content**: [what the image should show]
**Filename**: illustration-[slug].png

---

## Illustration 2
...
```

### Step 4: Create Prompt Files

Save prompts to `prompts/` directory with style-specific details.

**Prompt Format**:

```markdown
Illustration theme: [concept in 2-3 words]
Style: [style name]

Visual composition:
- Main visual: [description matching style]
- Layout: [element positioning]
- Decorative elements: [style-appropriate decorations]

Color scheme:
- Primary: [style primary color]
- Background: [style background color]
- Accent: [style accent color]

Text content (if any):
- [Any labels or captions in content language]

Style notes: [specific style characteristics]
```

### Step 5: Generate Images

**Image Generation Skill Selection**:
1. Check available image generation skills
2. If multiple skills available, ask user to choose

**Generation Flow**:
1. Call selected image generation skill with prompt file and output path
2. Generate images sequentially
3. After each image, output progress: "Generated X/N"
4. On failure, auto-retry once
5. If retry fails, log reason, continue to next

### Step 6: Update Article

Insert generated images at corresponding positions:

```markdown
![illustration description](imgs/illustration-[slug].png)
```

**Insertion Rules**:
- Insert image after corresponding paragraph
- Leave one blank line before and after image
- Alt text uses concise description in article's language

### Step 7: Output Summary

```
Article Illustration Complete!

Article: [article path]
Style: [style name]
Generated: X/N images successful

Illustration Positions:
- illustration-xxx.png → After section "Section Name"
- illustration-yyy.png → After section "Another Section"
...

[If any failures]
Failed:
- illustration-zzz.png: [failure reason]
```

## Notes

- Illustrations serve the content: supplement information, visualize concepts
- Maintain selected style consistency across all illustrations in one article
- Image generation typically takes 10-30 seconds per image
- Sensitive figures should use cartoon alternatives
- Prompt and illustration text language should match article language
