SEO Image Gen: AI Image Generation for SEO Assets (Extension)

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.

When to Use

• Use when generating OG images, hero images, schema visuals, infographics, or similar SEO assets.
• Use when image generation is part of a broader SEO or publishing workflow.
• Use only when the required image-generation extension is available.

Architecture Note

This skill has two components with distinct roles: - SKILL.md (this file): Handles interactive /seo image-gen commands for generating images - Agent (agents/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)

Prerequisites

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.

Quick Reference

SEO Image Use Cases

Each use case maps to pre-configured banana parameters:

Generation Pipeline

For every generation request:

1. Identify use case from command or context (og, hero, product, etc.)
2. Apply SEO defaults from the use cases table above
3. Set aspect ratio via set_aspect_ratio MCP tool
4. Construct Reasoning Brief using the banana Creative Director pipeline:
5. Load references/prompt-engineering.md for the 6-component system
6. Apply domain mode emphasis (Subject 30%, Style 25%, Context 15%, etc.)
7. Be SPECIFIC and VISCERAL: describe what the camera sees
8. Generate via gemini_generate_image MCP tool
9. Post-generation SEO checklist (see below)

Check for Presets

If the user mentions a brand or has SEO presets configured:

python3 ~/.claude/skills/seo-image-gen/scripts/presets.py list

Load matching preset and apply as defaults. Also check references/seo-image-presets.md for SEO-specific preset templates.

Post-Generation SEO Checklist

After every successful generation, guide the user on:

1. Alt text:Write descriptive, keyword-rich alt text for the generated image
2. File naming:Rename to SEO-friendly format: keyword-description-widthxheight.webp
3. WebP conversion:Convert to WebP for optimal page speed: bash magick output.png -quality 85 output.webp
4. File size:Target under 200KB for hero images, under 100KB for thumbnails
5. Schema markup:Suggest ImageObject schema for the generated image: json { "@type": "ImageObject", "url": "https://example.com/images/keyword-description.webp", "width": 1200, "height": 630, "caption": "Descriptive caption with target keyword" }
6. OG meta tags:For social preview images, remind about: html <meta property="og:image" content="https://example.com/images/og-image.webp" /> <meta property="og:image:width" content="1200" /> <meta property="og:image:height" content="630" /> <meta property="og:image:alt" content="Descriptive alt text" />

Cost Awareness

Image generation costs money. Be transparent: - Show estimated cost before generating (especially for batch) - Log every generation: `python3 ~/.claude/skills/seo-image-gen/scripts/cost_tracker.py log
