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 | $0.00090 | $0.02056 |
| Opus 5.5 | $0.00036 | $0.00822 |
| Sonnet 5.5 | $0.00018 | $0.00411 |
| Haiku 4.5 | $0.00009 | $0.00206 |
Grade A, and why
seo-geo scanned grade A 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

91% identical to seo-geo — 20 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.

SEO/GEO Optimization Skill
Comprehensive SEO and GEO (Generative Engine Optimization) for websites. Optimize for both traditional search engines (Google, Bing) and AI search engines (ChatGPT, Perplexity, Gemini, Copilot, Claude).
Quick Reference
GEO = Generative Engine Optimization - Optimizing content to be cited by AI search engines.
Key Insight: AI search engines don't rank pages - they cite sources. Being cited is the new "ranking #1".
Workflow
Step 1: Website Audit
Get the target URL and analyze current SEO/GEO status.
Basic SEO Audit (Free):
python3 scripts/seo_audit.py "https://example.com"
Use this for: Quick technical SEO check (title, meta, H1, robots, sitemap, load time). No API needed.
Check Meta Tags:
curl -sL "https://example.com" | grep -E "<title>|<meta name=\"description\"|<meta property=\"og:|application/ld\+json" | head -20
Use this for: Quick check of essential meta tags and schema markup on any webpage.
Check robots.txt:
curl -s "https://example.com/robots.txt"
Use this for: Verify which bots are allowed/blocked. Critical for ensuring AI search engines can crawl your site.
Check sitemap:
curl -s "https://example.com/sitemap.xml" | head -50
Use this for: Verify sitemap structure and ensure all important pages are included for search engine discovery.
Verify AI Bot Access:
# These bots should be allowed in robots.txt:
- Googlebot (Google)
- Bingbot (Bing/Copilot)
- PerplexityBot (Perplexity)
- ChatGPT-User (ChatGPT with browsing)
- ClaudeBot / anthropic-ai (Claude)
- GPTBot (OpenAI)
Step 2: Keyword Research
Use WebSearch to research target keywords:
WebSearch: "{keyword} keyword difficulty site:ahrefs.com OR site:semrush.com"
WebSearch: "{keyword} search volume 2026"
WebSearch: "site:{competitor.com} {keyword}"
Analyze:
- Search volume and difficulty
- Competitor keyword strategies
- Long-tail keyword opportunities
- International keyword conflicts (e.g., "OPC" = industrial automation in English markets)

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.
