## Workflow

### Progress

```
- [ ] Step 1: Setup & Analyze
- [ ] Step 2: Confirm Settings ⚠️ REQUIRED
- [ ] Step 3: Generate Outline
- [ ] Step 4: Generate Images
- [ ] Step 5: Finalize
```

### Step 1: Setup & Analyze

**1.1 Load Preferences (EXTEND.md)**

Use Bash to check EXTEND.md existence (priority order):

```bash
# Check project-level first
test -f .baoyu-skills/baoyu-article-illustrator/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md" && echo "user"
```

┌──────────────────────────────────────────────────────────┬───────────────────┐
│                           Path                           │     Location      │
├──────────────────────────────────────────────────────────┼───────────────────┤

│  Result   │                                  Action                                   │
├───────────┼───────────────────────────────────────────────────────────────────────────┤
│ Found     │ Read, parse, display summary                                              │

└───────────┴───────────────────────────────────────────────────────────────────────────┘

**EXTEND.md Supports**: Watermark | Preferred type/style | Custom style definitions | Language preference

Schema: `references/config/preferences-schema.md`

**1.2 Analyze Content**

Read article, detect language, classify content.

| Analysis | Description |
|----------|-------------|
| Content type | Technical / Tutorial / Methodology / Narrative |
| Core arguments | 2-5 main points that MUST be visualized |
| Visual opportunities | Positions where illustrations add value |
| Recommended type | Based on content signals |
| Recommended density | Based on article length and complexity |

**1.3 Extract Core Arguments**

Extract 2-5 core arguments that MUST be visualized:
- Main thesis
- Key concepts reader needs
- Comparisons/contrasts being made
- Framework/model proposed

**CRITICAL**: If article uses metaphors (e.g., "电锯切西瓜"), do NOT illustrate literally. Visualize the **underlying concept** instead.

**1.4 Identify Positions**

**What to Illustrate**:
- Core arguments (REQUIRED)
- Abstract concepts needing visualization
- Data comparisons, metrics
- Processes, workflows

**What NOT to Illustrate**:
- Metaphors literally
- Decorative scenes without information
- Generic illustrations

### Step 2: Confirm Settings ⚠️

**Do NOT skip.** Use AskUserQuestion with 3-4 questions in ONE call.

**Question 1: Illustration Type**

Based on content analysis, recommend type:
- [Recommended type based on signals] (Recommended)
- infographic - Data visualization, charts
- scene - Atmospheric, mood rendering
- flowchart - Process, steps
- comparison - Side-by-side contrast
- framework - Concept relationships
- timeline - Chronological progression
- mixed - Combine multiple types

**Question 2: Density**

- minimal (1-2 images) - Core concepts only
- balanced (3-5 images) (Recommended) - Major sections
- rich (6+ images) - Comprehensive visual support

**Question 3: Style**

Based on recommended Type, suggest compatible styles (see Type × Style Compatibility matrix):
- [Best compatible style for recommended type] (Recommended)
- [Other highly compatible styles: ✓✓ from matrix]
- [Compatible styles: ✓ from matrix]

**Question 4** (only if source ≠ user language):
- Language: Source language / User language

### Step 3: Generate Outline

Based on confirmed Type + Density + Style, generate illustration outline.

**Outline Format** (`outline.md`):

```yaml
---
type: infographic
density: balanced
style: blueprint
image_count: 4
---

## Illustration 1

**Position**: [section] / [paragraph]
**Purpose**: [why this illustration helps]
**Visual Content**: [what to show]
**Type Application**: [how type applies here]
**Filename**: 01-infographic-concept-name.png

## Illustration 2
...
```

**Outline Requirements**:
- Each illustration position justified by content needs
- Type applied consistently across all illustrations
- Style characteristics reflected in visual descriptions
- Count matches density selection

### Step 4: Generate Images

**4.1 Create Prompts**

Follow Prompt Construction principles below. Save each to `prompts/illustration-{slug}.md`.

**4.2 Select Generation Skill**

Check available image generation skills. If multiple, ask user to choose.

**4.3 Apply Watermark** (if enabled in preferences)

Add to prompt: `Include a subtle watermark "[content]" positioned at [position] with approximately [opacity*100]% visibility.`

**4.4 Generate**

1. Generate sequentially
2. After each: "Generated X/N"
3. On failure: auto-retry once, then log and continue

### Step 5: Finalize

**5.1 Update Article**

Insert after corresponding paragraph:
```markdown
![description](illustrations/{slug}/NN-{type}-{slug}.png)
```

Alt text: concise description in article's language.

**5.2 Output Summary**

```
Article Illustration Complete!

Article: [path]
Type: [type name]
Density: [minimal/balanced/rich]
Style: [style name]
Location: [directory path]
Images: X/N generated

Positions:
- 01-infographic-xxx.png → After "[Section]"
- 02-infographic-yyy.png → After "[Section]"

[If failures]

```

## Prompt Construction

### Principles

Good prompts must include:

1. **Layout Structure First**: Describe composition, zones, flow direction
2. **Specific Data/Labels**: Use actual numbers, terms from article
3. **Visual Relationships**: How elements connect
4. **Semantic Colors**: Meaning-based color choices (red=warning, green=efficient)
5. **Style Characteristics**: Line treatment, texture, mood
6. **Aspect Ratio**: End with ratio and complexity level

### Type-Specific Prompts
