Do I need an external API key to use this skill?

Yes, this skill requires a Google Gemini API key (set as GEMINI_API_KEY) and the google-genai Python package to perform the image generation.

What visual style does Brand Illustrator produce?

It produces hand-drawn ink line art on a warm off-white background with a single bold accent color, intentionally avoiding photorealism, 3D effects, or gradients.

Which accent colors are supported by the skill?

The system is locked to four specific brand-compliant colors: Coral, Teal, Indigo, and Amber to ensure visual consistency.

What types of images can I generate?

You can create three distinct types: Icons (single primary objects), Scenes (2–4 objects in a suggested environment), and Periphery (decorative corner or edge elements).

How does the concepting phase work?

Before generating any image, the skill uses a mapping reference to propose three distinct conceptual options (A, B, and C) for your approval, ensuring the final visual matches your content's meaning.
