This is a comprehensive SEO crawler that actually delegates work to up to 15 specialist subagents depending on what it detects about your site. Point it at a URL and it crawls up to 500 pages, figures out if you're running an ecommerce store or a local business, then spins up the right combination of agents for technical checks, content analysis, schema validation, and Core Web Vitals. The scoring system is transparent with defined weights, and it generates both markdown reports and optional PDFs with charts. It's smart about optional integrations too, only spawning the Google API agent if you have credentials configured, same with DataForSEO for SERP data. Good for when you need an actual audit, not just a Lighthouse score.
