What is nano-banana-2-asset-skill?

This repository provides a plugin, called a skill, for two AI coding tools: Codex and Claude Code. The skill helps those tools generate images for software projects. When a coding agent recognizes that a project needs a photograph, illustration, or other bitmap image, this skill creates a layout-aware prompt, generates the image using a Google service called Antigravity, and places the finished file into the code. The name "Nano Banana 2" refers to the specific image generation route used inside Antigravity. The plugin itself does not check or verify the underlying model on each run. A key feature is that the skill acts as a visual router. It sends requests for photos, illustrations, and textures to the Antigravity service. However, it leaves simple graphics like SVG icons, gradients, and shadows as code to be handled natively. The plugin does not use a separate Gemini API key. Instead, it relies on your existing Google login session through the Antigravity command line tool. The plugin itself never reads or stores your login tokens. Installation involves adding the plugin from this GitHub marketplace and then enabling it inside your coding tool. Once installed, the skill can activate automatically when the agent thinks an image is needed. You can also call it directly with a specific command, providing details like the target file path and the desired dimensions for desktop and mobile screens. Natural language requests, such as asking it to replace a placeholder with a production-ready image, also work. The skill manages usage limits carefully. If the Antigravity service reports a rate limit error, the plugin catches it, reports the cooldown time, and leaves your project files untouched. It avoids making new requests until the limit resets. For privacy, only the visual prompt and any reference images you select are sent to Google. The plugin collects no telemetry. Google notes that using third-party software like Claude Code with an Antigravity login may violate its terms, so users should review the rules before use.
