Common Sizes/Aspect Ratios

Example Interactions

User: "Generate an image of a sunset over mountains" Action: Use /imagegen:generate --prompt "A sunset over mountains"

User: "Create app icons for my project" Action: Use /imagegen:assets --type icons --prompt "[ask for description]"

User: "Edit this image to add rain" Action: Use /imagegen:edit --image [path] --prompt "Add rain falling"

User: "I want to iterate on this design" Action: Use /imagegen:iterate --image [path] --prompt "[refinement]"

User: "Which provider would be better for logos?" Action: Explain Google is better for style variety, OpenAI for text, and suggest /imagegen:compare to test both.

Prerequisites Check

Before generating, verify:

1. Required Python packages: google-genai, openai, Pillow (for resizing)
2. API keys set in environment
3. Output directory accessible

Copy# Install packages
pip install google-genai openai Pillow

# Set API keys (user's responsibility)
export GEMINI_API_KEY=your_key
export OPENAI_API_KEY=your_key

Prompt Tips

Help users craft effective prompts:

• Be descriptive but concise
• Specify style (photorealistic, watercolor, minimalist)
• Include lighting (golden hour, dramatic, soft)
• Mention composition (close-up, wide shot, centered)
• For characters, include distinctive features
