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

Most static findings are false positives caused by Markdown code formatting and relative documentation links. One instruction executes bundled Python connector commands against live email data, and saved worklists may retain sensitive subscriber information.

Medium
SKILL.md:52
Ruby/shell backtick execution
**Zero-dependency ESP read + measurement loop (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_
The line explicitly instructs the agent to run Python connector and ledger commands against live email-account data. Execution is intended and can access or persist sensitive operational data.

Risk findings

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

RISK-001 Medium
SKILL.md:39-40SKILL.md:70
Subscriber Data Retention Without Explicit Controls
The skill can save segmented subscriber worklists and engagement summaries to persistent memory. It does not specify field minimization, access controls, or retention periods for this sensitive data.
The file explicitly directs storage of a segmented worklist and reusable hygiene summary. Subscriber-level exports and worklists commonly contain addresses and engagement history.

Remediation

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

  1. FIX-001
    Medium
    The Resend measurement workflow invokes local connector and ledger commands.
    Require user confirmation before execution, validate list identifiers, quote every argument, and document the connector data scope.
  2. FIX-002
    Medium
    Saved hygiene worklists may retain subscriber addresses and engagement history.
    Minimize subscriber fields, redact reports when possible, restrict access, and define retention and deletion rules for saved results.

Expert evidence
