seo-image-gen

seo-image-gen is an agent for Claude Code from AgriciDaniel/seo-os. It costs 42 tokens per session (545 once invoked), scanned A, original, AGPL-3.0.

An SEO review of images used for social and search previews. OG images are the pictures shown when a page link is shared on platforms that support Open Graph metadata.

In plain words
What is it for?
It audits existing OG and social preview images, identifies key pages needing better images, and prepares an image-generation plan with prompts.
Why use it?
It finds missing or weak preview images that can make shared pages look incomplete or less representative. It turns those findings into a plan rather than changing images automatically.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

seo-image-gen scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
