Nano Banana

This is a wrapper around the Gemini CLI's nanobanana extension for generating images through natural language commands. You get shortcuts for blog headers, YouTube thumbnails, app icons, flowcharts, and photo restoration, all piped through Gemini's image models. It defaults to the flash model at around four cents per image, with options to bump up to the pro version for 4K output. The skill enforces using the yolo flag to skip confirmation prompts, which makes sense in an automated context but means you're trusting the prompt interpretation. Honestly most useful if you're already in a terminal workflow and want to skip opening a separate image tool for quick mockups or content visuals.
