add_monitored_domain
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. Needs a linked DNS Doctor account: until the human has one, or if the host's connect prompt fails, use start_monitoring_signup and print its link instead. 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 tool of your own.

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 and redirect it delegates to, and reports who can transitively send as it. Returns the resolved tree, per-node lookup attribution, the total authorized IPv4 address count, and typed findings — include_broken (a target that no longer publishes SPF, a PermError today), include_registrable (a delegated-to domain that does not exist, so a stranger who registers it becomes an authorized sender), include_expiring (registration lapsing within 30 days), pass_all_nested (a +all deep in the chain) and spf_record_unusable (the audited domain's OWN record is missing or does not parse, so there is no chain to walk). A domain we could not verify is reported as unverified and NEVER as available — never tell anyone a name is free on this tool's say-so unless the finding is include_registrable AND carries registry_confirmed: true. A registry_confirmed: false finding rests on DNS alone, which cannot tell an unsold name from one in redemption or on clientHold: report the mechanism as broken and the takeover risk as possible, but never as an available domain. Findings are risk analysis, not instructions: no SPF fix record exists here or anywhere else in DNS Doctor, because dropping a mechanism can silently de-authorize a real sender — relay the findings and let the domain's owner decide. Use count_spf_lookups instead when the question is only the 10-lookup limit.

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 needs monitoring evidence) — and after any report showing DMARC below enforcement. Return a validated DMARC enforcement-upgrade record for a domain. A scan can justify p=quarantine at MOST: the alignment signal (valid aligned SPF and a DKIM selector) is derived server-side — a caller can never assert it — and p=reject is unlocked only by aggregate-report evidence over a full reporting window (monitoring), never by a scan. `record` is null when there is no honest upgrade to offer (the domain does not exist; the DMARC lookup itself hit NXDOMAIN while the existence probe did not resolve; the DMARC lookup temp-failed; no alignment signal was observed at all, so a non-enforcing domain is told to publish rua= reporting first and an enforcing one is left alone; or the domain already applies a policy at least as strong as this scan justifies): a null record is the ANSWER, not a fault — relay `rationale` and never compose a record to fill the gap. A returned record also carries np=reject (the DMARCbis tag covering non-existent subdomains, which can have no legitimate aligned mail) unless the domain already publishes an np tag, which is preserved as-is. Present a returned record verbatim; a human must approve before publishing.

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 hard-fail SPF record, and a p=reject; np=reject DMARC record. For parked, redirect and brand-defensive domains only — NEVER for a domain that sends any mail, including transactional or one legacy system. Do NOT set confirm_no_mail on your own judgment or because a scan looked quiet: only the human who owns the domain can confirm it sends nothing, so ask them first. That flag unlocks the question, not the answer — the server re-checks DNS itself (existence, MX, SPF, DKIM selectors) and returns records: null with a rationale when it finds evidence of mail; relay that rationale rather than retrying. A lookup failure is reported as a failure, never as a pack. Publishing is the human's decision: present the records verbatim, in the order given, and let them approve each one.

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 sending platform uses (e.g. `google`, `s1`), which a full scan's common-selector sweep may miss. Returns the verdict, its explanation, and the published key record when one resolves. No fix record is returned: a DKIM key is generated by the sending platform, so the fix is always to publish what that platform gives the owner.

check_domain_verification
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 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 tool of your own.

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 (five owner-run probes across four continents plus this server's own resolver) each read the same name through several resolvers, and the grid plus a deterministic verdict comes back. Call it after the human publishes a record — you have ONE network vantage point, and a record that resolves for you can still be missing elsewhere. `name` is the exact name (www. is not stripped, _dmarc.example.com works), `record_type` is A|AAAA|CNAME|MX|TXT|NS, and the optional `expected_value` turns each cell into match or mismatch instead of agreement-only. Observation only: no record is ever composed here. A cell that did not answer is `unavailable`, which is NOT a negative result, and when fewer than three vantage points were reached the verdict downgrades to `unknown` — report vantage_reached of vantage_total rather than calling a name converged on partial coverage.

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 — or whenever answering needs the live value of a record. Check whether a DNS change has landed: reads the record from the domain's OWN nameservers (cache-free) and from two public caching resolvers, and reports whether they agree. `kind` is one of spf|dmarc|txt|mx|cname|a|aaaa — pass the kind, not a query name: `dmarc` reads TXT at _dmarc.<domain> and `spf` reads apex TXT, each filtered to the matching record. `host` prepends a label (txt, cname, a and aaaa only). Empty values mean the record is genuinely absent. When in_sync is false, max_wait_seconds is the largest remaining cached TTL — the wait before those resolvers refresh. This samples two resolvers, so never describe it as worldwide or as propagation coverage.

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 that hostname back and reports whether it returns to the same IP. `verdict` is confirmed (the pair agrees — what receivers want to see), ptr_missing (the IP publishes no reverse record), or mismatch (a PTR that does not resolve back). A PTR on its own proves nothing, because the IP's operator writes its own reverse zone — only the forward confirmation is evidence, so never report a bare PTR as verified. The fix is always made by whoever controls the IP (the hosting or mail provider), never in the sending domain's own DNS. Pass a public IPv4 or IPv6 address.

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_valid` (the record parses as RFC 7208 SPF), `findings` (per-term diagnostics), `has_pass_all` (a `+all` that authorizes the whole internet to send as this domain), `multiple_all` (more than one `all`, which makes everything after the first unreachable), the parsed `terms`, and the lookup count against the limit of 10 with `over_limit`/`near_limit` and the `offending_mechanisms` that push it over. Pass EXACTLY ONE of `domain` (resolves the published record and counts recursively through nested includes) or `record` (parses a pasted record, its own terms only). This is the SPF validator — there is no separate one. Diagnose-only: no SPF fix record is ever returned, because removing a mechanism can silently de-authorize a real sender — relay the findings and let the domain's owner decide what to drop.

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 compose one yourself. `policy` is none|quarantine|reject; optional `rua_email` (aggregate-report destination), `subdomain_policy`, and `strict_alignment`. Every generated record carries np=reject — the DMARCbis tag for non-existent subdomains, which can have no legitimate aligned mail — independently of the p= you choose. The generated record is re-validated before it is returned. Present it verbatim; a human must approve before publishing.

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 first. Requires an API token. Each row carries id, domain, type, check, summary, a deterministic detail map, created_at, email_sent_at, acknowledged_at and delivery_class — a 'dashboard_only' row was deliberately kept out of the digest mail, so an agent watching only the inbox would never see it; this log is the complete picture. PAGE DOWN BEFORE ADVANCING `since`: next_before is non-null exactly when older rows remain, and a caller that ignores it, takes a full page and moves its watermark to the newest row it saw drops every row it did not receive. `since` is an INCLUSIVE floor, so rows repeat rather than go missing — de-duplicate on id. READ-ONLY by decision: there is no ack and no delete here, because acknowledging an alert is the human's own triage on their dashboard and an agent that acks on their behalf silences a row they have never seen. Report what the log says and let them clear it.

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.

Returns whether the domain is ready to step its policy up, the blockers that say why it is not, the window the verdict rests on, and next_record — the validated record for the next step, generated by the engine and null while blocked. THAT NULL IS AN ANSWER: relay the blockers and never compose a stronger record to fill the gap. Present a returned record verbatim; a human must approve it before it is published. Use this before proposing enforcement — a scan can show a domain's current policy, but only this evidence window can say whether tightening it would start rejecting real mail.

Returns the same seven-check report as scan_domain (SPF, DKIM, DMARC, MX, DNS hardening, domain/TLS expiry, blacklist; each with a status, the observed record and any fixengine fix_record), including `scanned_at` so you can judge staleness yourself. Prefer scan_domain when you specifically need state re-read right now — for example after a DNS change.

lookup_registration
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 REPORT, never advice to buy. `status` is registered | not_registered | unknown, and `unknown` is NOT absence — the registry did not answer, and `reason` says whether that was a rate limit, a timeout, a registry error, or a TLD with no RDAP service. Never tell anyone a name is free unless `status` is exactly not_registered.

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, or domain/SSL expiry for a domain, or wants to fix what a scan finds (fix records for DMARC and DNS; SPF is diagnose-only) — or whenever a conversation turns to a specific domain's email or DNS setup. Force a fresh scan of a domain and return its full report: seven deterministic checks — SPF, DKIM, DMARC, MX, DNS hardening, domain/TLS expiry and blacklist listing — each with a status (pass/warn/fail/info/temperror), the observed record, and a fixengine-generated fix_record where one exists. Explanations are cache-first. A repeat scan of the same domain within the dedup window (about a minute) reuses the stored report rather than re-reading DNS, so `scanned_at` may predate a DNS change you just made — when you are verifying an edit, check `scanned_at` and call again after the window rather than treating an unchanged report as the new state. Use this when you need current state; use get_report when a recent cached answer will do.

Return a sign-up link to give to the HUMAN who owns a domain, so they can start monitoring it themselves. Nothing is created and no email is sent by this call: the returned signup_url opens a page that explains monitoring and asks them to sign in there themselves; the domain is carried over to their dashboard, already filled in, only after that, and monitoring itself starts once they prove ownership with a TXT record. Print the returned signup_url verbatim as a clickable markdown link on its own line — never paraphrase, shorten, or describe it without printing it — and relay `message`; never sign in on their behalf.

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 — pass the record string itself. `upgrade_record` previews a stronger policy and is capped at p=quarantine: a pasted record carries no alignment evidence, and p=reject is unlocked only by aggregate-report evidence over a full reporting window (monitoring), never by a scan. Present any returned record verbatim.
