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 12d 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.

Origin

This is a copy

89% identical to seo-audit — 8 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.

Full Website SEO Audit

Process

  1. Fetch homepage: use scripts/fetch_page.py to retrieve HTML
  2. Detect business type: analyze homepage signals per seo orchestrator
  3. Crawl site: follow internal links up to 500 pages, respect robots.txt
  4. Delegate to subagents (if available, otherwise run inline sequentially):
    • seo-technical -- robots.txt, sitemaps, canonicals, Core Web Vitals, security headers
    • seo-content -- E-E-A-T, readability, thin content, AI citation readiness
    • seo-schema -- detection, validation, generation recommendations
    • seo-sitemap -- structure analysis, quality gates, missing pages
    • seo-performance -- LCP, INP, CLS measurements
    • seo-visual -- screenshots, mobile testing, above-fold analysis
    • seo-geo -- AI crawler access, llms.txt, citability, brand mention signals
    • seo-local -- GBP signals, NAP consistency, reviews, local schema, industry-specific local factors (spawn when Local Service industry detected: brick-and-mortar, SAB, or hybrid business type)
    • seo-maps -- Geo-grid rank tracking, GBP audit, review intelligence, competitor radius mapping (spawn when Local Service detected AND DataForSEO MCP available)
    • seo-google -- CWV field data (CrUX), URL indexation (GSC), organic traffic (GA4) (spawn when Google API credentials detected via python scripts/google_auth.py --check)
    • seo-backlinks -- Backlink profile data: DA/PA, referring domains, anchor text, toxic links (spawn when Moz or Bing API credentials detected via python scripts/backlinks_auth.py --check, or always include Common Crawl domain-level metrics)
    • seo-cluster -- Semantic clustering analysis (spawn when content strategy signals detected: blog, pillar pages, topic clusters)
    • seo-sxo -- Search experience analysis: page-type mismatch, user stories, persona scoring (always include in full audits)
    • seo-drift -- Drift analysis: compare against stored baseline (spawn when drift baseline exists for the URL via python scripts/drift_history.py <url>)
    • seo-ecommerce -- Product schema, marketplace intelligence (spawn when E-commerce industry detected)
  5. Score -- aggregate into SEO Health Score (0-100)
  6. Report -- generate prioritized action plan

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.
