Workflow

User describes what they need ("I need a banner for the repo")
Claude constructs a 5-component prompt
Prompt is sent to the chosen backend via MCP or API
Image is saved to project assets/
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

Backend	Via	Best For
Gemini 3.1 Flash Image	AI Gateway	General purpose, fast, cheap
DALL-E 3	OpenAI API	Photorealistic, detailed
Flux 2	Replicate/fal.ai	Artistic, stylized
Stable Diffusion	Local/API	Full control, custom models
