What this skill does

Generate or edit images from text prompts. Use when the user asks to create, draw, design, or edit an image, illustration, photo, icon, poster, or any visual content. Generate and edit images using AI models. The script automatically picks a backend based on which API keys are configured — you don't need to specify a model unless the user explicitly names one. Never guess or invent a model: when the user doesn't name one, omit model entirely so the configured default/provider is used.

When it triggers

  • Use when the user asks to create, draw, design, or edit an image, illustration, photo, icon, poster, or any visual content.
