Where are the generated images saved?

Images are automatically saved to your current working directory using a standardized yyyy-mm-dd-hh-mm-ss-name.png format to ensure they stay within your project context.

Can I edit existing images with this skill?

Yes, by using the --input-image flag, you can provide an existing image and use a text prompt to describe the specific changes or edits you want to apply.

What image resolutions does Nano Banana Pro support?

The skill supports three resolution tiers: 1K (~1024px), 2K (~2048px), and 4K (~4096px). Users are encouraged to use 1K for drafting and 4K for final exports.

How does the skill handle API authentication?

The skill looks for a GEMINI_API_KEY environment variable by default, but you can also provide a key directly in the command using the --api-key argument.
