audit_spf_includes
Use this when the user asks who can send email as their domain through SPF includes, or wants an SPF supply-chain or third-party sender audit. Audit a domain's SPF supply chain: walks every include a…
build_dmarc_upgrade
Use this when the user asks how to move DMARC on from p=none, whether it is safe to tighten DMARC, or what the next DMARC policy step is for a domain (a scan can justify quarantine at most; reject ne…
build_parked_domain_records
Use this when the user asks how to protect a domain that sends no email from being spoofed. Build the three-record hardening pack that makes a NON-SENDING domain unusable for spoofing: a Null MX, a h…
check_dkim_selector
Use this when the user asks whether DKIM is set up for a sending platform, whether a specific selector exists, or why DKIM fails. Check ONE specific DKIM selector on a domain — the exact selector the…
check_propagation
Use this when the user asks whether a DNS change has propagated globally, or why a record shows in one place and not another. Check whether a DNS change has propagated GLOBALLY: six vantage points (f…
check_record
Use this when the user asks whether a DNS change has landed, wants a DNS record looked up, or wants to verify a record they just published. Check whether a DNS change has landed: reads the record fro…
check_reverse_dns
Use this when the user asks about reverse DNS, PTR records, or FCrDNS for a mail server IP. Check one sending IP's forward-confirmed reverse DNS (FCrDNS): reads the IP's PTR record, then resolves tha…
count_spf_lookups
Use this when the user asks about SPF 'too many lookups', the 10-lookup limit, an SPF PermError, or whether an SPF record is valid. Validate an SPF record and count what it costs. Returns `record_val…
generate_dmarc_record
Use this when the user asks to create, generate or write a DMARC record for a domain that has none. Build a DMARC record from scratch for a domain that has none, using a validating engine — never com…
get_alerts
Use this when a signed-in operator asks what changed on a monitored domain, or what the monitoring has flagged. Read the monitoring alert log for the domains the caller's account monitors, newest fir…
get_readiness
Use this when a signed-in operator asks whether a monitored domain is ready for the next DMARC step. Read the DMARC enforcement-readiness verdict for ONE domain the caller's account monitors, compute…
get_report
Use this for the same questions as scan_domain when a recent report is enough (the cheap first look); use scan_domain when the state must be re-read now. Return the stored report for a domain, scanni…
parse_dmarc_report
Use this when the user uploads or pastes a DMARC aggregate (RUA) XML report and asks what it says. Parse ONE DMARC aggregate (RUA) report into readable per-source aggregates: who sent mail as the dom…
scan_domain
Use this when the user asks to check, audit, diagnose or troubleshoot SPF, DKIM, DMARC, email authentication, email deliverability DNS, why their mail lands in spam, MX, DNS health, blacklist status,…
start_monitoring_signup
Use this when the user wants DMARC monitoring, RUA report monitoring, new-sender monitoring, email-authentication alerts, ongoing DNS monitoring, or to start a DNS Doctor trial. Return a sign-up link…
validate_dmarc_record
Use this when the user pastes a DMARC record and asks whether it is valid, correct or safe. Validate a pasted DMARC record: parsed tags, level'd findings, and whether it is valid. No DNS lookup — pas…
