Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

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

Most static findings are false positives caused by Markdown links, code-style labels, and prompt examples. The remaining confirmed issues are optional connector instructions that execute local Python scripts and may use RESEND_API_KEY, which require explicit consent and credential safeguards.

Capability review items (3)
High
SKILL.md:52
Generic API/secret keys
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
The skill explicitly references RESEND_API_KEY for an optional connector, so an agent may use a secret from the environment. Even read-only ESP access can expose account metadata if mishandled.
Medium
SKILL.md:52
Ruby/shell backtick execution
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
The skill instructs the agent to run a Python connector from CLAUDE_PLUGIN_ROOT and use a Resend account context. This is real external command execution touching ESP data and should require explicit user consent.
Medium
SKILL.md:54-60
Ruby/shell backtick execution
**Zero-dependency S1 record pull (keyless, works for any ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scr
The skill instructs the agent to run a local Python DNS-over-HTTPS connector with a user-provided domain. This is legitimate deliverability tooling, but it still executes external code and performs network lookups.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

Remediation

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

  1. FIX-001
    High
    Optional connector uses an environment API key.
    Gate RESEND_API_KEY use behind explicit user approval, document read-only scope, and avoid printing secrets or raw account data.
  2. FIX-002
    Medium
    Skill instructions include local Python connector execution.
    Require confirmation before running connector commands, validate domain and selector inputs, and describe the network lookup behavior.
  3. FIX-003
    Low
    Many documentation links traverse outside the skill directory.
    Replace parent-directory links with packaged local references or marketplace-safe cross-skill references when possible.
