Generate or edit images using the Antigravity-hosted Gemini image model via the local gateway. Use when the user asks to create an image, generate an avatar, or edit/transform an existing image with text instructions. Supports text-to-image and image-to-image editing.
Use the Gemini REST endpoint (via the local gateway base URL) to create or edit images. This skill wraps the correct request format for the gemini-3.1-flash-image model, which does not work reliably with /v1/responses + image_generation.
