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

agentic-seo 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/audit_build.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agentic SEO

Repeatable workflow for auditing and implementing SEO on a web page. Standard SEO practice applies; the reference files hold the checks, templates and decisions specific to this skill.

First-Time Setup: Gather Site Configuration

Before running any sub-command for the first time in a session, ask the user for their website details if not already known. Store these as working context:

Setting Ask For Example
Site Name "What is your site/company name?" Acme Corp
Domain "What is your website domain?" https://acme.com
X/Twitter Handle "What is your X/Twitter handle?" (optional) @acme_corp
Social Image Path "Where are your social sharing images stored?" /assets/social/
Social Links "Any social profile URLs?" (optional) Twitter, GitHub, LinkedIn URLs
Framework "What framework is your site built with?" Angular, React, Next.js, etc.
Build Output Path "Where does your built/prerendered HTML output to?" dist/apps/web/browser/
Sitemap Path "Where is your sitemap.xml?" public/sitemap.xml

If the project has a CLAUDE.md with SEO patterns already defined, read it and extract these values automatically instead of asking.

Use these values as {SITE_NAME}, {DOMAIN}, {TWITTER_HANDLE}, {SOCIAL_IMAGE_PATH}, {BUILD_OUTPUT}, {SITEMAP_PATH} throughout all sub-commands.

When to use this skill

Trigger this skill when:

  • A new page is created and needs SEO implementation
  • An SEO audit is requested on an existing page
  • Structured data (JSON-LD) needs to be added or updated
  • llms.txt or llms-full.txt needs maintenance
  • A quick checklist verification is needed before deploying
  • A page is missing meta tags, OG tags, canonical URL, or sitemap entry

Dated 2026-10-10: Google's guide "Optimizing your website for generative AI features on Google Search" (https://developers.google.com/search/docs/fundamentals/ai-optimization-guide, last updated 2026-07-10) says you don't need new machine readable files, AI text files, markup or Markdown to appear in Google Search; structured data isn't required for generative AI search and there is no special schema.org markup to add; Google Search doesn't use llms.txt, and having one neither harms nor helps visibility or rankings there; content does not need to be broken into tiny pieces. Standard SEO applies; re-check the guide before relying on this.

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.
