Workflow

Copy this checklist and track progress:

Progress:
- [ ] Step 1: Pre-check
- [ ] Step 2: Setup & Analyze
- [ ] Step 3: Confirm Settings ⚠️ REQUIRED
- [ ] Step 4: Generate Outline
- [ ] Step 5: Generate Images
- [ ] Step 6: Finalize

Step 1: Pre-check

1.1 Determine Input Type

1.2 Determine Output Directory (file path input only)

Check default_output_dir in preferences:

AskUserQuestion (when no preference):
- {article-dir}/ - Same directory as article
- {article-dir}/imgs/ - Images subdirectory
- {article-dir}/illustrations/ - Illustrations subdirectory (Recommended)
- illustrations/{topic-slug}/ - Independent directory
- Save as default - Remember this choice for future runs

1.3 Check Existing Images

Scan target directory for .png/.jpg/.webp files.

If images exist → AskUserQuestion: How to handle?
- supplement - Keep existing, generate only new positions
- overwrite - Overwrite same-name files
- regenerate - Clear all and regenerate

1.4 Confirm Article Update Method (file path input only)

AskUserQuestion: How to update article?
- update - Modify original file directly
- copy - Create {name}-illustrated.md copy

1.5 Load Preferences (EXTEND.md)

test -f .baoyu-skills/baoyu-article-illustrator/EXTEND.md && echo "project"
test -f "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md" && echo "user"

Supports: Watermark | Preferred type/style | Custom styles | Language | Output directory

Step 2: Setup & Analyze

2.1 Analyze Content

2.2 Extract Core Arguments

• Main thesis
• Key concepts reader needs
• Comparisons/contrasts
• Framework/model proposed

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

2.3 Identify Positions

Illustrate:
- Core arguments (REQUIRED)
- Abstract concepts
- Data comparisons
- Processes, workflows

Do NOT Illustrate:
- Metaphors literally
- Decorative scenes
- Generic illustrations

Step 3: Confirm Settings ⚠️

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

Q1: Illustration Type
- [Recommended based on analysis] (Recommended)
- infographic / scene / flowchart / comparison / framework / timeline / mixed

Q2: Density
- minimal (1-2) - Core concepts only
- balanced (3-5) (Recommended) - Major sections
- rich (6+) - Comprehensive support

Q3: Style (ALWAYS ask, even with preferred_style in EXTEND.md)

If EXTEND.md has preferred_style:
- [Custom style name + brief description] (Recommended)
- [Top compatible built-in style 1]
- [Top compatible built-in style 2]
- [Top compatible built-in style 3]

If no preferred_style:
- [Best compatible from matrix] (Recommended)
- [Other ✓✓ style 1]
- [Other ✓✓ style 2]
- [Other ✓ style]

Style selection based on Type × Style compatibility matrix (references/styles.md).
Full specs: references/styles/<style>.md

Q4 (only if source ≠ user language):
- Language: Source / User language

Step 4: Generate Outline

Save as outline.md:

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

## Illustration 1

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

## Illustration 2
...

Requirements:
- Each position justified by content needs
- Type applied consistently
- Style reflected in descriptions
- Count matches density

Step 5: Generate Images

5.1 Create Prompts

Follow references/prompt-construction.md. Save to prompts/illustration-{slug}.md.

5.2 Select Generation Skill

Check available skills. If multiple, ask user.

5.3 Apply Watermark (if enabled)

Add: Include a subtle watermark "[content]" at [position].

5.4 Generate

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

Step 6: Finalize

6.1 Update Article

Insert after corresponding paragraph:

![description](illustrations/{slug}/NN-{type}-{slug}.png)

Alt text: concise description in article's language.

6.2 Output Summary

Article Illustration Complete!

Article: [path]
Type: [type] | Density: [level] | Style: [style]
Location: [directory]
Images: X/N generated

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

[If failures]
Failed:
- NN-zzz.png: [reason]

Output Directory

illustrations/{topic-slug}/
├── source-{slug}.{ext}
├── outline.md
├── prompts/
│   └── illustration-{slug}.md
└── NN-{type}-{slug}.png

Slug: 2-4 word topic in kebab-case.
Conflict: Append -YYYYMMDD-HHMMSS if exists.
