When your agent uses it

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).

# quien — domain & IP lookup tool

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)
