Can I change the aspect ratio of generated images?

Yes, the skill supports square (1024x1024), portrait (1024x1536), and landscape (1536x1024) formats, or you can use 'auto' to let the model decide.

What is the difference between regular editing and mask-based inpainting?

Regular editing applies modifications to the entire image, while inpainting uses a transparent PNG mask to define the specific area where the AI should add or change content.

Where are the generated images saved?

Images are saved directly to your current working directory using a standardized naming convention that includes a timestamp and a short descriptive slug.

Does this skill support transparent backgrounds?

Yes, during image generation, you can use the --background transparent parameter to generate PNG or WebP images with alpha transparency.

How do I provide my OpenAI API key to the skill?

You can either set the OPENAI_API_KEY environment variable in your system or pass the --api-key argument directly during the command execution if Claude has access to it.
