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-link-checker.
