What it does. Generates and edits images by calling Google’s Gemini image models, with style presets, sizing for YouTube, slides and blog, variants, reference images for style transfer, and a resolution option.
What it needs. A Gemini API key in the GEMINI_API_KEY environment variable. Usage is billed or limited by Google under your plan; check current pricing and free-tier limits on Google’s page.
What we checked. Generated two YouTube thumbnails; the second came out at exactly 1280 by 720 and was usable and on-prompt when we looked at it. A caution: the copy we installed shipped the author’s encrypted secrets file, which we deleted. Check any skill you install for files like that, and never commit keys.
