This handles both sitemap analysis and generation with a smart opinion layer baked in. Point it at an existing sitemap and it runs protocol validation plus quality checks like finding noindexed URLs you shouldn't have included or spotting those suspicious identical lastmod dates. The generation mode is more opinionated, it pulls from industry templates and actually warns you at 30 location pages, then hard stops at 50 unless you justify it, trying to keep you from building thin programmatic content that tanks your rankings. The distinction between safe scaled pages like integration docs versus penalty risk pages like city name swap location spam is genuinely useful. Outputs proper XML with automatic index file splitting at 50k URLs.
