DNS Doctor 1.9.0 — 20 tools.
- New: lookup_registration — who a domain is registered with, when it expires, its nameservers, DNSSEC and transfer/delete locks, from one RDAP read. Observation only; a registry that did not answer is reported as unknown, never as "not registered".
- New, for hosts that support OAuth linking: add_monitored_domain, check_domain_verification and get_domain_records let a linked agent add a domain to monitoring, run the ownership check and read the records to publish. Every tool now declares securitySchemes; the sixteen existing tools behave exactly as before, and the hand-off link path is unchanged for hosts that cannot link.
- Tool descriptions widened so agents pick the right tool from conversation context, not only from an explicit ask.
- Client route tables, skill and guidance updated for all 20 tools.
