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-technical-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.

Technical Audit

A one-shot technical SEO audit for a domain. Pulls SE Ranking's audit data, categorizes findings by area (crawlability, indexability, security, mobile, structured data, etc.), severity-sorts within each, and produces a top-10 fix list ranked by impact × effort.

Prerequisites

  • SE Ranking MCP server connected.
  • Claude's WebFetch tool available (used for sense-checking robots.txt and sitemap presence).
  • User provides: a target domain (e.g. example.com). Optional: target country (default us), audit-page-limit override (default: rely on the existing audit's limit).

Process

  1. Validate target & preflight. See skills/seo-firecrawl/references/preflight.md for the canonical 3-stage preflight (credit balance, Firecrawl availability, Google APIs). Skill-specific notes:

    • Normalise domain (strip protocol, trailing slash) before continuing.
    • Estimated SE Ranking cost for this skill: a re-check of an existing audit is cheap; creating a new audit is significantly more expensive and varies by page count. Surface the cost before deciding.
    • Firecrawl: optional. When available, step 8 (Modern signals checklist) runs on 5 sample URLs and /robots.txt, ~6 Firecrawl credits (hard cap). Without it, step 8 is skipped — JS-render canonical/noindex divergence, X-Robots-Tag headers, and AI-crawler robots-rule analysis are unavailable but the full technical-audit deliverable still ships. Pass --no-firecrawl to skip step 8 even when Firecrawl is available (saves credits).
    • Google APIs: tier 0 unlocks step 8b (CrUX field data); tier 1 also unlocks step 8c (per-URL GSC Inspection on top 5 traffic pages). See skills/seo-google/references/cross-skill-integration.md § "seo-technical-audit" for the full recipe and per-tier branches.
  2. Find or create the audit DATA_listAudits

    • List audits for the domain.
    • If a recent audit exists (<30 days old), use it.
    • If older than 30 days, run DATA_recheckAudit to refresh.
    • If none exists, ask the user before creating a new one with DATA_createStandardAudit (it consumes credits).
    • Wait for DATA_getAuditStatus to report done before pulling the report.

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.
