Image Generation

Use this skill when you need to create one or more image files from a text prompt, or edit one or more existing images with Gemini.

Requirements

• GEMINI_API_KEY must be available in the environment.
• GEMINI_MODEL_ID must be available in the environment and should point to a model that supports image output. For image editing, it should support image input as well.
• GEMINI_BASE_URL is optional in the environment for custom endpoints, and should not have a trailing slash if provided.
• Node.js must be installed in the workspace environment.
• Install dependencies once with npm install from the workspace root.

When To Use

• The user asks to generate a new image from a text prompt.
• The user asks to modify, restyle, extend, or otherwise edit one or more existing images.
• The user wants the generated image saved to a workspace file.
• The task should be handled through a reusable OpenClaw skill instead of ad hoc SDK code.
