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-deep-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 10d 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.

SEO Deep Audit — orchestrator: provide a domain -> get everything

One entry point for a complete audit. When given a domain without a specified scope, work at maximum depth: run the entire chain of skills and tools yourself, collect everything, and consolidate it into one report + task plan. Narrow the work only when EXPLICITLY instructed ("only robots," "quick," "lite," "no rendering," "check only headings"). The map of "which tool retrieves what" is in the sf-boundaries skill.

If you need a plan for exactly what to collect before expensive runs, start with audit-roadmap (Recon lite -> roadmap with priorities, scale, site type, and YAGNI), and then this skill executes the roadmap.

Default rule

  • No scope clarification -> MAX. Run every phase below.
  • Explicitly narrowed scope -> only that scope. "only sitemap" -> only the sitemap portion; "quick/lite" -> --profile lite + skip expensive agent-level phases.
  • Never ask "should I do a full audit?" — a full audit is the default. Clarify only what makes progress impossible (no domain; SF is not installed and no exports are available).

Pipeline (all phases by default)

Phase 0 — Reconnaissance (what kind of site is this?). The seo-recon skill — three toolkit tools:

seohead domain-profile --domain <domain>   # registration, DNS, ASN, geography, TLS, flags
seohead cdn-check       --url https://<domain>   # CDN + actual cache behavior, HTTP/2-3, TTFB
seohead tech-detect     --url https://<domain>   # CMS/framework/server, analytics, pixels

Remember the stack: if tech-detect found an SPA/Next.js/Nuxt, mark JS rendering as required (Phase 2). Some findings from domain-profile.flags and cdn-check.findings go directly into the report.

Phase 1 — Crawl evidence (96-check registry). SEOHEAD is the analyzer and adapter here, not the crawler. Check the environment first with seohead sf doctor; live mode requires a separately installed, actively licensed Screaming Frog CLI.

seohead sf run --crawl https://<domain> --out report --tasks

The full profile is the default (maximum available coverage), and the sitemap is automatically obtained from robots. The registry contains 96 checks, but only checks supported by the available exports and enabled SF modules can run. If the output contains many skipped results (MIXED_CONTENT/STRUCTURED_DATA/SPELLING/DOM_*), enable them once through the sf-config skill (create audit.seospiderconfig); the tool will pick it up automatically. If SF/a license is not available, request exports and use mode B (--exports-dir); see sf-analyzer/sf-config.

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.
