  • domain_diagnosewrite actionFree

    Runs a comprehensive health check on a public domain: SPF / DKIM / DMARC for the headline score, plus optional details on email-auth adjacent records (MX, BIMI, MTA-STS, TLS-RPT, DKIM key length), DNS infrastructure (NS, DNSSEC, CAA, AAAA, SOA, TXT), web security (HTTPS, certificate, HSTS, HTTP/2-3, CT log), domain registration (RDAP expiry, registrar lock, DS chain), and brand protection (typosquatting, TLD parity). Returns a structured report with per-category scores, individual diagnostic items, and a `critical_issues` cross-cut summary. No authentication required.
