Provides a unified command-line toolkit for researching domains and IPs. quien wraps WHOIS/RDAP, DNS queries, mail configuration checks (SPF/DMARC/DKIM), TLS certificate inspection, HTTP header and redirect analysis, SEO surface checks including Core Web Vitals hints, and tech-stack detection — all with JSON output suitable for automated agents.
Activate when the user asks about domain ownership, registrar and expiry, nameservers and DNS records, email configuration and deliverability, SSL certificate details, HTTP response headers and redirects, SEO health or CWV signals, or when identifying the CMS/framework and hosting stack. Use quien all for a full diagnostic.
Best for CLI-capable agents and automation pipelines that consume JSON output (Copilot/Codex/CLI-focused agents).
