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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00118 | $0.01180 |
| Opus 5 | $0.00059 | $0.00590 |
| Sonnet 5 | $0.00024 | $0.00236 |
| Haiku 4.5 | $0.00012 | $0.00118 |
Grade A, and why
ultimate-seo-geo-skill 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ultimate SEO & GEO Skill
The definitive SEO and Generative Engine Optimization (GEO) skill. Runs scored full-site audits (0-100 Health Score), generates ready-to-deploy fixes, and optimizes for Google Search + AI search engines (AI Overviews, AI Mode, ChatGPT, Perplexity).
Covers 21 SEO modules: technical SEO, Core Web Vitals, on-page, E-E-A-T, schema/JSON-LD, keywords, links, local SEO, hreflang, programmatic SEO, and site migrations. Includes CORE-EEAT (80-item) and CITE (40-item) scoring frameworks plus 24 diagnostic Python scripts.
Three Modes
| Mode | Purpose | Output |
|---|---|---|
| Audit | Full-site health assessment | Scored report (0-100) with prioritized issues |
| Plan | Strategy from audit findings | Actionable roadmap with effort/impact matrix |
| Execute | Implement fixes | Ready-to-deploy code, markup, and configs |
When to Use
Use when the user mentions SEO, GEO, audit, schema, rankings, traffic drop, AI citations, backlinks, sitemap, crawl, robots.txt, migration, hreflang, snippets, content strategy, or any visibility or traffic-loss question.
Example prompts:
- "Audit mysite.com"
- "Generate schema markup for my product page"
- "How do I get cited by ChatGPT and Perplexity?"
- "We're migrating to Shopify -- what about SEO?"
- "Why did my traffic drop?"
- "Fix my robots.txt"
- "Optimize for AI Overviews"
- "Check my Core Web Vitals"
- "Build a keyword strategy for [topic]"
- "Is my content E-E-A-T compliant?"
- "Run a technical SEO check"
- "Set up hreflang for my multi-language site"
When NOT to Use
- PPC / Google Ads / paid advertising campaigns
- Social media management or posting
- General marketing strategy unrelated to organic search
- Web design or UX beyond SEO-relevant elements
- Full article writing (generates briefs and meta tags, not complete articles)
- GA4/GTM-only setup with no organic SEO question
- Employer branding / press distribution without an organic search component

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.
