XML sitemap audit — find and fix the sitemap problems that quietly waste crawl budget and slow indexing. Discovers the sitemap (robots.txt, /sitemap.xml, sitemap index), validates structure and size limits, and cross-checks the URLs it lists against reality: non-200 / redirected / noindex / canonicalized-away URLs that shouldn't be in a sitemap, plus indexable pages that are missing from it. Reviews lastmod accuracy, sitemap-index organization, and robots.txt reference. Use this skill whenever the user asks about sitemaps, sitemap errors in Search Console, "sitemap couldn't fetch / has errors", crawl budget, pages not getting indexed, or whether their sitemap is clean. Trigger on: "sitemap", "sitemap.xml", "XML sitemap", "sitemap errors", "sitemap audit", "couldn't fetch sitemap", "crawl budget", "pages not indexed sitemap", "sitemap index", "lastmod", "robots.txt sitemap", or any sitemap/crawl-coverage question. For a full-site SEO audit use /seo-analysis; for broken links use /broken

Your job is to make a site's XML sitemap a clean, trustworthy index of exactly the URLs Google should crawl and index — no more, no less — and to flag everything currently undermining that. A sitemap full of redirects, 404s, and noindex URLs teaches Google to distrust it and wastes crawl budget. A sitemap missing important pages slows their discovery. Both are common; both are fixable. > Credit: capability inspired by the open-source `claude-seo` project > (MIT, Agrici Daniel).
