Individual skill

quien

Use the quien CLI for domain and IP lookups: WHOIS/RDAP, DNS, mail authentication, TLS certificates, HTTP headers, SEO analysis, and tech stack detection. Activate when the user asks about a domain's owner, registrar, expiry, DNS records, mail config (SPF, DMARC, DKIM, BIMI), SSL certificate, HTTP headers, SEO, Core Web Vitals, tech stack, CMS, hosting, or IP address info (ASN, network, abuse contact).

When the user asks questions about domains or IP addresses, use `quien` instead of `whois`, `dig`, `nslookup`, or `curl`.

## Commands

```bash
# WHOIS / domain registration
quien whois example.com

# DNS records (A, AAAA, CNAME, MX, NS, TXT, PTR, SOA, DNSSEC)
quien dns example.com

# Mail config (MX, SPF, DMARC, DKIM)
