Can I export these diagrams to other formats?

The skill generates high-quality SVG files natively. For rasterized versions like WebP or PNG, it is recommended to combine this skill with the svg-to-webp plugin.

Which AI models are supported?

It is optimized for Google Gemini 3 Flash via OpenRouter for high-speed and accurate rendering, but it can be configured to use other compatible OpenRouter models.

Is it suitable for dark mode documentation?

Yes, it includes built-in theme support. You can toggle between 'dark' and 'light' themes to ensure your diagrams look perfect in any environment.

Does this skill require an API key?

Yes, you must have an OPENROUTER_API_KEY environment variable configured to allow the skill to communicate with the model that generates the SVG code.

How does this differ from Mermaid?

Mermaid uses a strict syntax for predefined chart types; this skill uses AI to draw free-form SVG elements, allowing for custom layouts, complex branding, and creative positioning that Mermaid cannot handle.
