| check_domain_expiry | Domain registration expiry via RDAP: registrar, registered/expires dates, days left, status, nameservers. | Read-only |
| check_email_auth | Email authentication posture for a domain: SPF validity and lookup count, DMARC policy, DKIM on common selectors, MTA-STS mode, TLS-RPT, BIMI, a rough 0-100 score and plain-English fixes. Live DNS. | Read-only |
| check_security_headers | HTTP security headers for a site from one live HTTPS request: redirect chain, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, an A-F grade and findings. | Read-only |
