Usage

After installation and configuration, just talk to Claude:

"Astraler tạo ảnh một thành phố cyberpunk về đêm"
"nhờ Astraler vẽ ảnh, tỷ lệ 16:9"
"dùng Astraler generate image of a snowy mountain"
"Astraler draw me a logo for a coffee shop"
"tạo ảnh bằng Astraler phong cách anime"

Note: This skill only activates when you say "Astraler" — generic image requests go to the platform's built-in tool.
