What problem does it solve? Sitemaps often drift out of sync with the actual site: URLs appear in the sitemap that are never linked internally, and crawlable pages are missing from the sitemap entirely. This Skill fetches and validates sitemap.xml files, cross-checks URL coverage against crawled pages, and enforces sitemap best practices so search engines index the right pages. ## Core Features & Use Cases - Sitemap Parsing & Validation: Fetches /sitemap.xml or a sitemap index and validates its structure via scripts/parse-sitemap.ts. - Coverage Gap Detection: Identifies orphan URLs (in sitemap but not linked) and missing URLs (linked but not in sitemap). - Special Sitemap Support: Covers sitemap-news.xml (last-48h articles for publishers), sitemap-image.xml, and sitemap-video.xml, plus robots.txt sitemap references. - Use Case: After a site migration, run the Skill to confirm every new URL is in the sitemap, no stale URLs remain, and robots.txt correctly references the sitemap with HTTPS absolute URLs. ## Quick Start Analyze the sitemap at https://example.com/sitemap.xml and report any orphan or missing URLs compared to the crawled pages.
