How do I provide an API key for image generation?

You must set either the GOOGLE_API_KEY or GEMINI_API_KEY environment variable. You can obtain a key for free from Google AI Studio.

What is the maximum resolution supported?

The skill supports three resolution tiers: 1K for previews, 2K for standard use, and 4K for high-quality production assets.

Can I use existing images as a style reference?

Yes, you can use the --reference flag followed by the file path. You can provide up to 5 reference images to guide the style or subject of the generation.

Where are the generated images saved?

By default, images are saved to a './generated/' directory with a timestamped filename. You can specify a custom location using the --output argument.
