Genimage
Generate, edit, or create any image — photos, illustrations, icons, thumbnails, hero images, banners, placeholder visuals, website graphics, social media assets, product shots, logos, diagrams, or any visual content. Use this skill whenever the task involves creating an image, populating a UI with visuals, generating placeholder or mockup images, editing or retouching a photo, applying style transfer, composing multiple images, or producing any graphic asset. Triggers on requests like "generate an image", "create a visual", "make a placeholder", "add a hero image", "design a thumbnail", "edit this photo", "create website graphics", "populate with images", or any task requiring image creation or manipulation.From its SKILL.md

Nano Banana — Image Generation
Generate and edit images via the Gemini API. If the API key is missing, run /nano-banana:setup.
Workflow
-
Determine the mode from the user's request:
- Creating a new image from text? → Text-to-image (no
--images) - Editing/retouching an existing image? → Image editing (
--images source.png) - Applying one image's style to another? → Style transfer (
--images style.png target.png) - Combining or referencing multiple images? → Multi-image (
--images a.png b.png ..., up to 14) - Need 2K or 4K output? → Add
--resolution 2K|4Kto any mode above
- Creating a new image from text? → Text-to-image (no
-
Craft the prompt — describe the desired result narratively. See references/prompting-guide.md for domain-specific patterns (website visuals, placeholders, product shots, etc.).
-
Run the script:
python "$CLAUDE_PLUGIN_ROOT/scripts/genimage.py" --prompt "..." [options]
- Show the result — read the output image and present it to the user.

Editing
All editing is text-guided — describe what to change ("replace the sky", "remove the person", "add a sunset") and Gemini identifies and modifies regions automatically. No masks needed.
