Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.02019 |
| Opus 5.5 | $0.00030 | $0.00808 |
| Sonnet 5.5 | $0.00015 | $0.00404 |
| Haiku 4.5 | $0.00007 | $0.00202 |
Grade B, and why
seo-image-gen scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
This skill requires the nanobanana MCP server (Gemini image generation) registered in the project's `.mcp.json`, with a Google AI Studio key in the `GEMINI_API_KEY` environment variable (key at https://aistudio.google.co This is a copy
84% identical to seo-image-gen — 48 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
Architecture Note
This extension is built on Claude Banana, the standalone AI image generation skill for Claude Code.
This skill has two components with distinct roles:
- SKILL.md (this file): Handles interactive
/seo image-gencommands for generating images - Agent (
agents/seo-image-gen.md): Audit-only analyst spawned during/seo auditto assess existing OG/social images and produce a generation plan (never auto-generates)
Prerequisites
This skill requires the nanobanana MCP server (Gemini image generation) registered in the project's .mcp.json, with a Google AI Studio key in the GEMINI_API_KEY environment variable (key at https://aistudio.google.com/apikey). No installer script ships with this pack.
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 nanobanana MCP server is not
configured and point to the setup above.

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

seo-image-gen is a skill published in the GitHub repository joaoguirunas/team-os (4 stars, last pushed 2d ago), licensed MIT. It adds 74 tokens to every session and 2,019 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads mcp configuration). It is 84% identical to seo-image-gen, differing in 48 lines, and is treated as a copy.
