Individual skill
dns-lookup
Query DNS records and domain registration data with zero API keys — DNS-over-HTTPS via dns.google and domain registration via RDAP, through plain curl. Use when asked what does this domain resolve to, check the MX or TXT records, who registered this domain, when does it expire, or has DNS propagated. Produces the records decoded (SPF/DKIM/DMARC read, not just dumped), the registration facts from RDAP, and the rerunnable commands.

# DNS Lookup Skill
DNS questions ("did the record propagate," "where's mail for this domain going," "who owns this") come with two keyless answers: Google's DNS-over-HTTPS for records, and RDAP — WHOIS's structured successor — for registration. This skill queries both, and does the part `dig` doesn't: decoding what the records *mean* — an SPF string into its policy, MX priorities into the actual mail provider, an expiry date into "renews in 6 weeks."
## What This Skill Produces
- **The records** — A/AAAA/MX/TXT/CNAME/NS/whatever was asked, with TTLs
- **The decode** — mail provider identified from MX, SPF/DMARC policies read out, CNAME chains followed
- **Registration facts** — registrar, creation/expiry dates, status codes (from RDAP; contact data is mostly redacted now, and the answer says so)
- **The commands** — exact curls, rerunnable
