A tool for comparing the URLs listed in a website's XML sitemap with pages that a crawler can find and Google has indexed. An XML sitemap is a file that tells search engines which pages a site considers important; GSC is Google Search Console.

Use it to audit sitemap coverage, find orphaned pages, check Google sitemap processing, and compare crawling and indexing results for a domain.

It reveals pages listed in the sitemap that cannot be reached, as well as reachable or indexed pages missing from the sitemap.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00139	$0.02963
Opus 5	$0.00069	$0.01482
Sonnet 5	$0.00028	$0.00593
Haiku 4.5	$0.00014	$0.00296

Security

Grade A, and why

seo-sitemap 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.

Sitemap Analysis

Compare a domain's XML sitemap against what's actually crawled and indexed — GSC indexed pages (get_search_analytics dimensions=["page"]), GSC sitemap ingestion (get_sitemap_details), and a DataForSEO on_page_instant_pages fetch loop over the declared/indexed URL set. Surface what the sitemap claims vs what's really reachable, in both directions.

Prerequisites

DataForSEO MCP server connected.
GSC (mcp__gscServer__*) recommended — it's the authoritative source for which pages Google indexes and which sitemaps Google ingested (the comparison baseline). Firecrawl optional — for URL discovery (firecrawl_map) when the sitemap is missing or suspect.
Claude's WebFetch tool available.
User provides: a target domain. Optional: the sitemap URL if not at /sitemap.xml (auto-discovery from robots.txt is attempted first).
Predecessor (recommended): seo-technical-audit on this domain — its discovered URL set + On-Page fetch results can be reused as the crawl baseline. Without it, this skill builds its own baseline from GSC indexed pages + an On-Page fetch loop.

Optional accelerator: if you have a hosted-crawl MCP you can substitute it for the URL-discovery + fetch loop — not required.

Process

Validate target & build the crawl baseline
- Normalise the domain.
- Build the "what's really crawled/indexed" baseline this skill compares the sitemap against:
  - GSC indexed pages — mcp__gscServer__get_search_analytics with dimensions=["page"] (pages Google indexes, with clicks/impressions). Authoritative for the user's own verified property.
  - DataForSEO On-Page fetch loop — mcp__dataforseo__on_page_instant_pages over the discovered URL set (declared sitemap URLs + GSC indexed pages), capped to a top-N ceiling — gives status code, redirects, indexability, depth signals per page.
  - DataForSEO top pages — mcp__dataforseo__dataforseo_labs_google_relevant_pages (broader domain page inventory than the sitemap in some cases).
- If seo-technical-audit already ran on this domain, reuse its discovered URL set + On-Page results as the baseline instead of re-fetching.
- Firecrawl availability check. If mcp__firecrawl-mcp__firecrawl_map is available, Mode-2 (URL discovery via crawl) is offered when the sitemap is missing or suspect. Cost: ~0.5 Firecrawl credits per URL discovered, hard cap 500 URLs (~250 credits). Without Firecrawl, the skill runs Mode-1 only and notes the gap if Mode-2 was needed. User may pass --no-firecrawl to force Mode-1 even when Firecrawl is available (saves credits at the cost of orphan/missing analysis when sitemap is broken).

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.
