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 ALL 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:

Send voice notification:

curl -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 &

Output text notification:

Running the WorkflowName workflow from the Art skill...

Workflow Routing

Route to the appropriate workflow based on the request.

Blog header or editorial illustration -> Workflows/Essay.md Visualization or chart -> Workflows/Visualize.md Mermaid flowchart or sequence diagram -> Workflows/Mermaid.md Technical or architecture diagram -> Workflows/TechnicalDiagrams.md Framework or 2x2 matrix -> Workflows/Frameworks.md Stat card or big number visual -> Workflows/Stats.md PAI pack icon -> Workflows/CreatePAIPackIcon.md Core Aesthetic

Default: Production-quality concept art style appropriate for editorial and technical content.

UL Editorial Color Palette:

Background: Light Cream #F5E6D3 or White #FFFFFF Primary Accent: Deep Purple #4A148C (strategic, 10-20%) Secondary Accent: Deep Teal #00796B (5-10%) Structure: Black #000000 Text: Charcoal #2D2D2D

Typography System (3-Tier):

Tier 1 (Headers): Valkyrie-style elegant wedge-serif italic Tier 2 (Labels): Concourse-style geometric sans-serif Tier 3 (Insights): Advocate-style condensed italic for callouts

Load customizations from: ~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Art/PREFERENCES.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:

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

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:

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

Examples

Example 1: Blog header image

User: "create a header for my AI agents post" -> Invokes ESSAY workflow -> Generates editorial illustration prompt -> Creates image with consistent aesthetic -> Saves to ~/Downloads/ for preview -> After approval, copies to public/images/

Example 2: Technical architecture diagram

User: "make a diagram showing the SPQA pattern" -> Invokes TECHNICALDIAGRAMS workflow -> Creates structured architecture visual -> Outputs PNG with consistent styling

Example 3: Framework visualization

User: "create a 2x2 matrix for security vs convenience" -> Invokes FRAMEWORKS workflow -> Creates hand-drawn framework visual -> Purple highlights optimal quadrant

Example 4: PAI pack icon

User: "create icon for the skill system pack" -> Invokes CREATEPAIPACKICON workflow -> Generates 1K image with --remove-bg for transparency -> Resizes to 256x256 RGBA PNG -> Outputs to ~/Downloads/ for preview
