    Example session with this skill installed

    Audit the following DNS records for my domain and tell me why my emails are landing in spam: v=spf1 include:_spf.google.com include:sendgrid.net ~all and v=DMARC1; p=none;

    • Read your context and instructions
    • Compiled the email auth deliverability

    Audit Findings

    • Rule ID: SPF-MULTIPLE-INCLUDE
    • Severity: High
    • Finding: SPF record looks valid but DMARC is set to p=none.
    • Evidence: p=none provides no protection against spoofing.
    • Remediation: Once delivery is confirmed, upgrade DMARC to p=quarantine.

    About this skill

    What it does

    The Email Auth Deliverability Doctor is a diagnostic tool designed to audit SPF, DKIM, and DMARC records for common misconfigurations that lead to high bounce rates and spam folder placement. It analyzes DNS zone files, dig outputs, or nslookup text to identify technical errors and alignment issues.

    Why use this skill

    Manually debugging email authentication records is error-prone. This skill automates the process by checking your records against a comprehensive audit checklist. It helps you catch syntax errors, multiple SPF records, missing DMARC policies, and misalignment between signing domains and sender addresses without the risk of an automated tool making unauthorized changes to your live DNS.

    Supported inputs

    • DNS zone file exports
    • Terminal output from dig or nslookup
    • Local DNS configuration text files

    What the output looks like

    The skill produces a structured audit report including the specific rule violated, the severity of the issue, direct evidence from your records, and clear remediation guidance to fix the deliverability problem.
