Plan six image-generation command formats for social previews, page heroes, product images, infographics, custom assets, and prompt variations.
By Daniel Agrici · Verified 2026-08-27 against the Claude SEO v2.2.5 source snapshot and current Google AI documentation.
The pinned MCP adapter is unavailable; the bundled direct API fallback is source-verified but execution-unverified. The adapter still maps to retired Gemini preview models. The fallback dispatch path is verified in the v2.2.5 source, but no paid current-model request was made here. Test the selected route with a supported model before any provider request.
MCP ROUTE BLOCKED // DIRECT FALLBACK NEEDS A CONTROLLED TEST
This reference is ready for planning. The pinned MCP route is blocked, while the documented direct fallback remains execution-unverified. Prepare the brief now, then repair the MCP route or complete a controlled fallback test before any provider call.
A command reference and repair plan, not a generated image.
An asset type and description. Audience, subject, style, composition, and constraints make the generated brief more useful.
Mixed. The pinned MCP adapter is blocked. The bundled direct API fallback is source-documented but has not been live-tested here.
A generated raster candidate that still needs exact cropping, web conversion, alt text, and human review.
A network request to Gemini, possible provider charges, and local file writes.
Confirm selected-route compatibility, current pricing, key handling, input rights, and final visual quality before publication.
Use this reference to prepare a brief and understand the intended command surface. Do not run the pinned MCP adapter until compatibility is restored. The documented direct fallback also needs a controlled current-model test. Once a selected route is verified, use generation only when the task needs a raster image and a human will review the result before publication.
Select the documented command form and describe the intended asset, audience, subject, style, composition, and constraints.
Repair the retired MCP model mappings or inspect the documented direct fallback with an explicitly supported model.
Inspect the connected tools and complete a controlled generation test with current pricing, limits, and write paths confirmed.
Inspect any returned image, crop to exact pixels, convert for the web, write alt text, and obtain human approval.
Syntax reference. The six forms below define the intended command surface. Execute them only after the selected route uses a supported model and passes a controlled test.
Claude SEO documents six command forms. The format defaults below belong to the extension contract. They do not prove current adapter compatibility or exact publication pixels.
| Command | Documented behavior |
|---|---|
/seo image-gen og <description> | Documents a 16:9, 1K social-preview concept. An approved result would still need a separate exact 1200 by 630 export. |
/seo image-gen hero <description> | Documents a 16:9, 2K editorial or cinematic hero concept. |
/seo image-gen product <description> | Documents a 4:3, 2K product image with the product-oriented prompt mode. |
/seo image-gen infographic <description> | Documents a 2:3, 4K infographic draft that would require label and data verification. |
/seo image-gen custom <description> | Documents the full creative-director workflow for an asset outside the preset formats. |
/seo image-gen batch <description> [N] | Documents N variations of one concept, with three as the stated default. |
This is syntax documentation, not a runnable example or a claim about a resulting file:
/seo image-gen og "Editorial illustration of a technical site audit becoming a prioritized action plan, dark matte palette, no text"
The intended output shape is an image and a reported file path. The pinned extension documentation names ~/Documents/nanobanana_generated/ as its expected directory, but no current output exists because neither documented generation route was run.
The Image Gen extension is optional. Inspect the pinned installer, but do not run this path unchanged:
./extensions/banana/install.sh
The reviewed script checks for Claude SEO, Node, and npx, copies the installable skill, agent, and Python utilities, and configures @ycse/nanobanana-mcp@1.1.1. That MCP package only maps to retired preview IDs. The script can also store GOOGLE_AI_API_KEY in the local Claude Code MCP configuration. Do not expose a key while repairing or testing either route.
| Layer | What is verified |
|---|---|
| Claude SEO | Defines the six command forms, use-case defaults, prompt workflow, and post-generation checklist. |
| MCP adapter | The pinned package maps only to two Gemini preview IDs that Google shut down on June 25, 2026. This route is unavailable until updated and tested. |
| Google Gemini API | Receives the generation request over the network. Provider pricing, usage limits, safety handling, and model availability apply. |
| Local files | The installer changes the local Claude Code skill, scripts, and MCP configuration. A successful MCP or direct API request writes the returned image to disk. |
On 2026-08-27, Google listed gemini-3.1-flash-image as a stable image model and listed no free API tier for that model. Standard output equivalents were USD 0.045 for 0.5K, 0.067 for 1K, 0.101 for 2K, and 0.151 for 4K, before applicable input, thinking, or grounding charges. These values are dated facts, not permanent guarantees. Check Google's current pricing and your active project limits before a paid or multi-image run.
The command does not publish the asset or establish that it is correct. A human still needs to inspect the visual, verify any depicted facts, create exact web exports, decide appropriate alternative text, and update visible page content and metadata.
@ycse/nanobanana-mcp@1.1.1. Its two allowed preview models are shut down, so the installed MCP route is unavailable as documented.skills/seo-image-gen/SKILL.md says Claude SEO does not vendor a local generation fallback. The installable extensions/banana/skills/seo-image-gen/SKILL.md instead routes MCP failures to the bundled direct API utility, and the installer copies that skill and its scripts. The fallback is source-verified but execution-unverified because it was not installed or live-tested here.gemini-3.1-flash-image-preview and gemini-3-pro-image-preview as shut down on June 25, 2026, with stable replacements. The pinned adapter rejects other model IDs, so this is an integration failure, not a generic future risk.Tool behavior was checked against the Claude SEO v2.2.5 source snapshot. Provider claims were checked against Google-owned documentation on 2026-08-27.
2384fdd9. The two skill files conflict about fallback status, so the page separates source verification from live execution. View the reviewed source.@ycse/nanobanana-mcp@1.1.1. That package maps its Flash and Pro choices only to gemini-3.1-flash-image-preview and gemini-3-pro-image-preview. Google lists both as shut down on June 25, 2026, so the adapter must be updated and tested before use.
