This report does not block or authorize the manifest or ZIP.

Most static alerts are false positives caused by Markdown backticks, relative documentation links, HTML terms, and email-client compatibility guidance. The Resend test-send instruction is a confirmed external-command capability with an optional live network action, although its stated scope is limited to user-owned test inboxes.

SKILL.md:54
Ruby/shell backtick execution
**Zero-dependency render-test send (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scrip
The line instructs the agent to invoke a Python Resend connector and optionally use --live to send email. The stated own-inbox restriction lowers abuse risk, but command execution and a consequential network action are real.

Risk findings

Confirmed security concerns are separated from items that still need review.

  1. FIX-001
