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

Most static findings are false positives from Markdown code fences, inline file paths, and relative documentation links. One external command is confirmed because line 52 documents a Python connector command that can perform live Resend suppression with --live. No prompt injection or data-exfiltration intent was found in SKILL.md.

Ruby/shell backtick execution
**Zero-dependency ESP sync (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts/conne
Line 52 instructs running python3 with a connector script and includes a --live suppress command. This is a real external-command path with live ESP side effects, although it is scoped to Resend.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
Live ESP Contact Suppression Side Effect
Line 52 documents a Resend suppress command with --live that can change contact subscription state. This is legitimate but account-impacting without explicit confirmation.
The command and --live flag are explicit, and the text says it pushes suppression to the platform. The skill also states dry-run defaults, which lowers severity.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Live ESP connector command
    Keep connector sync dry-run by default, require explicit user confirmation for --live, and validate subscriber identifiers before execution.
  2. FIX-002
    Low
    PII in list exports
    Document that saved reports must contain aggregate counts and rules only, never raw email addresses or member rows.
