The Agent Skills Directory

[SAFE]: The skill consists entirely of Markdown documentation and reference materials. It does not include executable scripts, binaries, or automated tasks that could compromise the host system.
[EXTERNAL_DOWNLOADS]: The documentation references legitimate external resources including the official Resend documentation (resend.com), Google Postmaster Tools, and well-known email diagnostic services like mail-tester.com and MXToolbox. These are industry-standard tools for email administration.
[COMMAND_EXECUTION]: Instructions provide examples of using standard network diagnostic commands such as dig for DNS verification. These are used for manual troubleshooting by the developer and are not executed autonomously by the agent.
[REMOTE_CODE_EXECUTION]: Code snippets provided for user implementation reference the 'svix' library for webhook signature verification. This is a well-known, legitimate package for processing webhooks securely.
[DATA_EXFILTRATION]: No patterns of sensitive data access or external transmission were detected. The skill focuses on outbound email logic and does not request access to local credentials or private files.
