Added "check_bimi" (26 tools before, 27 now)
Check BIMI Logo Setup — Use this when the user asks how to get their logo shown in Gmail, Yahoo, Apple Mail or other inboxes (BIMI), whether their BIMI setup works, or why their logo does not show. A live read of one host's BIMI setup: the DMARC gate (BIMI needs p=quarantine or p=reject; dmarc_sources names each policy read and why it does or does not count), the published default._bimi record, the logo (fetched and checked as SVG Tiny PS) and any certificate (certificate.trust_verified is true for a mark certificate for this host, in date, chaining to a Mark Verifying Authority root, false with trust_reason when no…

Changed the definition of "check_domain_verification" and "scan_domain"
Use this only for DNS Doctor's own ownership TXT challenge on a domain the user already added to their DNS Doctor account (add_monitored_domain). For a TXT record another service asked for (Google Workspace, Microsoft 365, Shopify or any site verification), use check_record instead. Check whether the ownership TXT record for a ⟨127 unchanged words⟩

List Email Tests — Use this when a signed-in user asks about email tests they ran before, or how a sender's earlier tests scored. Requires an API token with monitoring:read. Returns the account's own tests, newest first (optionally only those whose From names one organization): each with test_id, status, created_at, received_at, from_domain, score (value out of out_of), dmarc_result and report_url. Print report_url as a clickable link; call get_email_test with a test_id for the full result. Read-only.
Added "get_email_test" and "start_email_test" (22 tools before, 24 now)
Get Email Test Result — Use this after start_email_test, once the user says they sent the email. Returns status pending | received | expired | error. pending means the message has not arrived (or is still being checked): ask the user to send it if they have not, then call again. received carries result — the sending IP and reverse DNS, STARTTLS, SPF, every DKIM signature, DMARC with alignment and the disposition the policy implies, message hygiene, blocklist status, and a deterministic score out of 10 with every deduction itemized — plus advice. A 'temperror' is a lookup that did not complete, NOT a failure, and is …
Start Email Test — Use this when the user wants to know how a real email from them actually authenticates — whether a message from Google Workspace, Microsoft 365, a newsletter tool or an app is SPF/DKIM/DMARC aligned, why it lands in spam, or to prove DKIM signing works before tightening DMARC. Returns a single-use address (valid about an hour, one message) and a test_id. Tell the user to send one email to that address from the sender they want to test, then call get_email_test with the test_id. Each call creates a new address and counts toward a daily limit; limit says which one applied.

Use this when the user asks about lookalike, look-alike, typosquat or impersonation domains of their domain, or whether someone has registered a name close to theirs. DNS-only: checks the closest variants of the name and returns facts — how many resolve and how many accept mail, with up to ten resolving names (each with the kind of variant, whether it accepts mail, and same_infra when it points at the domain's own nameservers or mail servers, which usually means the owner registered it defensively). Never a verdict: relay the names as facts and never call one malicious — resolving only means …

List My Domains — Use this when a signed-in operator asks which domains their DNS Doctor account monitors, or what to do next on them. Lists every domain on the caller's account with its state — verified, pending (added, ownership not proven yet) or verification_lapsed (the ownership record was removed, so monitoring is paused for it) — and next_step, the one thing to do next for that domain. Requires an API token. Relay next_step as given.

Add a domain to the signed-in user's DNS Doctor monitoring and return the ownership-check TXT record they must publish, plus where their DNS is hosted, a provider-specific guide link and, when their provider supports it, a one-click apply URL. Re-adding a domain they already monitor returns that domain rather than an error. Print every record host and value EXACTLY as returned — never rewrite, reformat or improve a record string. Nothing here is applied to anyone's DNS: a human publishes every record, and you must show them what you are about to add and get their approval before using any DNS…
Check whether the ownership TXT record for a domain the user has added is visible yet, and mark it verified when it is. The result says WHICH outcome occurred and which nameservers were asked, so you can tell 'not published yet' from 'published with the wrong value' from 'our lookup did not complete' — a lookup that did not complete is TRANSIENT, never a verdict about their DNS. On success the result also carries the DMARC reporting record that turns monitoring on. Print every record host and value EXACTLY as returned — never rewrite, reformat or improve a record string. Nothing here is appli…
Read the records a domain the user monitors still needs: the ownership check while it is unverified, and once verified the DMARC reporting record plus whether we have OBSERVED that record published. Read-only: it issues nothing — if a verified domain comes back with no reporting record yet, call check_domain_verification once, which issues it. Print every record host and value EXACTLY as returned — never rewrite, reformat or improve a record string. Nothing here is applied to anyone's DNS: a human publishes every record, and you must show them what you are about to add and get their approval …
Use this when the user asks who owns a domain, when it expires, which registrar or nameservers it has, whether it is registered, or whether a transfer or delete lock is set — the WHOIS question. Read a domain's registration from the registry over RDAP: registrar (with IANA id), registration/last-changed/expiry dates, EPP status codes verbatim, nameservers, whether the delegation is DNSSEC-signed, and an abuse contact where one is published — `redacted: true` is the post-GDPR norm, not a failure. Observation only: no record is composed, and `pendingDelete` or a near expiry is something to REPO…
