This applies to ALL workflows in this skill.
Route to the appropriate workflow based on the request.

User customization defines specific aesthetic preferences including:
Load from: ~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/Art/PREFERENCES.md
User customization may include reference images for consistent style.
Check ~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/Art/PREFERENCES.md for:
Usage: Before generating images, load relevant user-provided references to match their preferred style.
Default model: Check user customization at SKILLCUSTOMIZATIONS/Art/PREFERENCES.md
Fallback: nano-banana-pro (Gemini 3 Pro)
Each model accepts different --size formats. Using the wrong format causes validation errors.
| Model | --size format | Valid values | Default |
|---|---|---|---|
flux | Aspect ratio | 1:1, 16:9, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 21:9 | 16:9 |
nano-banana | Aspect ratio | 1:1, 16:9, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 21:9 | 16:9 |
nano-banana-pro | Resolution tier | 1K, 2K, 4K (also accepts --aspect-ratio separately) | 2K |
gpt-image-1 | Pixel dimensions | 1024x1024, 1536x1024, 1024x1536 | 1024x1024 |
Note: nano-banana-pro uses --size for resolution quality and a separate --aspect-ratio flag for aspect ratio (defaults to 16:9).
ALL generated images MUST go to ~/Downloads/ first for preview and selection.
Never output directly to a project's public/images/ directory. User needs to review images in Preview before they're used.
Workflow:
~/Downloads/[descriptive-name].pngcms/public/images/)# CORRECT - Output to Downloads for preview
bun run ~/.claude/skills/Media/Art/Tools/Generate.ts \
--model nano-banana-pro \
--prompt "[PROMPT]" \
--size 2K \
--aspect-ratio 1:1 \
--thumbnail \
--output ~/Downloads/blog-header-concept.png
# After approval, copy to final location
cp ~/Downloads/blog-header-concept.png ${PROJECTS_DIR}/YourWebsite/cms/public/images/
cp ~/Downloads/blog-header-concept-thumb.png ${PROJECTS_DIR}/YourWebsite/cms/public/images/
For improved character or style consistency, use multiple --reference-image flags:
# Multiple reference images for better likeness
bun run ~/.claude/skills/Media/Art/Tools/Generate.ts \
--model nano-banana-pro \
--prompt "Person from references at a party..." \
--reference-image face1.jpg \
--reference-image face2.jpg \
--reference-image face3.jpg \
--size 2K \
--aspect-ratio 16:9 \
--output ~/Downloads/character-scene.png
