Art Skill

Complete visual content system for creating illustrations, diagrams, and visual content.

Customization

Before executing, check for user customizations at: ~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/

If this directory exists, load and apply:

• PREFERENCES.md - Aesthetic preferences, default model, output location
• CharacterSpecs.md - Character design specifications
• SceneConstruction.md - Scene composition guidelines

These override default behavior. If the directory does not exist, proceed with skill defaults.

MANDATORY: Output to Downloads First

CopyALL GENERATED IMAGES GO TO ~/Downloads/ FIRST
NEVER output directly to project directories
User MUST preview in Finder/Preview before use

This applies to ALL workflows in this skill.

Voice Notification

When executing a workflow, do BOTH:

1. Send voice notification:

   Copycurl -s -X POST http://localhost:8888/notify \
     -H "Content-Type: application/json" \
     -d '{"message": "Running the WORKFLOWNAME workflow from the Art skill"}' \
     > /dev/null 2>&1 &
   

2. Output text notification:

   CopyRunning the **WorkflowName** workflow from the **Art** skill...

• Framework or 2x2 matrix -> Workflows/Frameworks.md
• Stat card or big number visual -> Workflows/Stats.md
• PAI pack icon -> Workflows/CreatePAIPackIcon.md

Image Generation

Default model: Check user customization at SKILLCUSTOMIZATIONS/Art/PREFERENCES.md Fallback: nano-banana-pro (best text rendering)

CRITICAL: Always Output to Downloads First

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:

1. Generate to ~/Downloads/[descriptive-name].png
2. User reviews in Preview
3. If approved, THEN copy to final destination
4. Create WebP and thumbnail versions at final destination

Copy# CORRECT - Output to Downloads for preview
bun run ~/.claude/skills/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/Website/cms/public/images/

Multiple Reference Images (Character/Style Consistency)

For improved character or style consistency, use multiple --reference-image flags:

Copy# Multiple reference images for better likeness
bun run ~/.claude/skills/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

API keys in: ${PAI_DIR}/.env
