How do I view the generated images on my machine?

Since terminal environments usually cannot render images, this skill uses the macOS 'open' command to automatically launch the generated file in your system's default image viewer.

Can I specify different aspect ratios?

Yes. The skill recognizes keywords like 'landscape', 'widescreen', 'portrait', or 'mobile' and automatically selects the corresponding 16:9 or 9:16 model variants.

How does the skill save on API costs?

The skill is configured with a 'Standard First' policy. It defaults to standard resolution models and only triggers high-cost 4K models if you explicitly use keywords like '4K', 'Ultra HD', or 'High Definition' in your prompt.

Which specific Gemini models are used?

The skill utilizes the gemini-3-pro-image family of models, including specialized versions for standard resolution and 4K across various aspect ratios.
