~1,692Tokens (Tool-Definitionen)
~18.3 KBTypische Antwortgröße
Mittlere Auswirkung auf die Aufmerksamkeit (1.32% von 128k Kontext)
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.

🟢check_domain(domain, dkim_selector, include_raw)
Audit the email-authentication DNS records of a domain. Returns a 0–100 score and A–F grade (MX 10, SPF 25, DMARC 30, DKIM 25, BIMI 10, plus up to 5 bonus points for MTA-STS and TLS-RPT, capped at 100), each check's status, published record, findings and recommended fixes, and a link to the full report. Read-only: it only queries public DNS and the domain's public MTA-STS policy file. Same engine and scoring as the DnsGuard JSON API (GET /api/check).
