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-audit 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 7d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/seo-audit — Technical SEO Analysis

Deep-dive SEO audit against Google's best practices. Checks on-page SEO, technical SEO, and social sharing metadata. Invoke when /launch-check's SEO row shows WARN or FAIL.

See also: /geo-audit for the LLM/agent-discoverability sibling check — llms.txt, AGENTS.md, AI-crawler directives in robots.txt, JSON-LD citation metadata, token economics. /seo-audit covers the Googlebot audience; /geo-audit covers the LLM-crawler and coding-agent audience. The two run independently; /launch-check fans out to both at milestone boundaries.

Process

Step 1: On-page SEO

Check each key page (index, about, pricing, blog, product pages) for:

  • <title> tag (exists, unique per page, 50-60 chars)
  • <meta name="description"> (exists, unique, 150-160 chars)
  • <h1> tag (exactly one per page, contains target keyword)
  • Heading hierarchy (h1 → h2 → h3, no gaps)
  • Internal linking between pages
  • Image alt text containing relevant keywords (not keyword-stuffed)

Step 2: Technical SEO

  • robots.txt at root (exists, not blocking important pages)
  • sitemap.xml at root (exists, lists all public pages, submitted to Search Console)
  • Canonical URLs (<link rel="canonical"> on each page)
  • 404 page exists and returns HTTP 404 (not 200)
  • Redirects: any redirect chains? (301 → 301 → page)
  • URL structure: clean, readable, no query-string-based routing for content pages
  • Mobile viewport meta tag: <meta name="viewport" content="width=device-width, initial-scale=1">

Step 3: Social sharing (Open Graph + Twitter Cards)

  • og:title, og:description, og:image, og:url on key pages
  • og:image dimensions (1200x630 recommended)
  • Twitter card meta tags (twitter:card, twitter:title, twitter:description, twitter:image)
  • Favicon and apple-touch-icon

Step 4: Structured data

  • JSON-LD or Microdata for relevant schemas (Organization, Product, FAQ, BreadcrumbList, Article)
  • Check validity: are required properties present?

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.
