Generate production-ready images for SEO use cases using Gemini's image generation via the banana Creative Director pipeline. Maps SEO needs to optimized domain modes, aspect ratios, and resolution defaults.
This extension is built on Claude Banana, the standalone AI image generation skill for Claude Code.
This skill has two components with distinct roles:
/seo image-gen commands for generating imagesagents/seo-image-gen.md): Audit-only analyst spawned during /seo audit to assess existing OG/social images and produce a generation plan (never auto-generates)This skill requires the banana extension to be installed:
./extensions/banana/install.sh
Check availability: Before using any image generation tool, verify the MCP server
is connected by checking if gemini_generate_image or set_aspect_ratio tools are
available. If tools are not available, inform the user the extension is not installed
and provide install instructions.

set_aspect_ratio MCP toolreferences/prompt-engineering.md for the 6-component systemgemini_generate_image MCP toolIf the user mentions a brand or has SEO presets configured:
python3 scripts/presets.py list
Load matching preset and apply as defaults. Also check references/seo-image-presets.md

{
"@type": "ImageObject",
"url": "https://example.com/images/keyword-description.webp",
