Art Director

Claude can't generate images directly, but it can direct image generation models with expert-level prompts. This skill turns Claude into a creative director.

The 5-Component Prompt Formula

Every image prompt follows this structure:

[SUBJECT] + [STYLE] + [COMPOSITION] + [LIGHTING] + [TECHNICAL]

1. Subject (What)

"A minimalist developer dashboard showing code metrics"
"An isometric illustration of microservices architecture"
"A cyberpunk cityscape representing a deployment pipeline"

2. Style (How it looks)

Styles: flat design, isometric, pixel art, watercolor,
        technical diagram, infographic, comic book,
        photorealistic, low-poly 3D, line art, blueprint

3. Composition (Layout)

"centered hero composition with negative space"
"rule of thirds with focal point bottom-left"
"symmetric grid layout with 4 quadrants"

5. Technical (Specs)

"16:9 aspect ratio, 1920x1080, PNG"
"1:1 square, 1024x1024, social media optimized"
"4:3 presentation slide format"
"banner format 1200x630 for Open Graph"

Composition: "left-to-right flow, clear hierarchy"
Lighting: "flat, no shadows, white background"
Technical: "SVG-compatible, high contrast"

3. Social Media Posts

Subject: "before/after comparison of code quality metrics"
Style: "modern infographic, data visualization"

4. Presentation Slides

Subject: "key takeaway slide showing 3 pillars of the system"
Style: "corporate minimal, sans-serif typography"

Workflow

1. User describes what they need ("I need a banner for the repo")
2. Claude constructs a 5-component prompt
3. Prompt is sent to the chosen backend via MCP or API
4. Image is saved to project assets/
5. Path is returned for immediate use

Integration

• designer agent: Uses art-director skill for visual decisions
• frontend-dev: Generates placeholder images during prototyping
• copywriter: Creates social media visuals with copy
• doc-updater: Generates diagrams for documentation
• harvest: Creates competitive analysis visuals

Tips

• Always specify aspect ratio and dimensions
• Include "no text" if you don't want the model to attempt typography
• Use negative prompts: "no watermark, no stock photo look"
• For diagrams, prefer SVG-compatible styles over photorealistic
• Test with cheapest model first, upgrade only if quality insufficient
