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 hits are false positives from Markdown backticks, relative documentation links, repository URLs, and deliverability terminology. The optional Python connector commands and RESEND_API_KEY are real risk surfaces because they execute local scripts and handle credentials. No evidence of prompt injection, data exfiltration intent, or malicious business logic was found.

Capability review items (3)
High
Generic API/secret keys
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
Line 52 requires RESEND_API_KEY for optional Resend automation. The file does not show exfiltration, but use of a live API secret by an external helper is a real credential-handling risk.
Medium
Ruby/shell backtick execution
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
Line 52 tells the agent to run a Python connector from ${CLAUDE_PLUGIN_ROOT} that uses RESEND_API_KEY. This is a real external-command and credential-handling surface, although the stated purpose is read-only ESP verification.
Medium
Ruby/shell backtick execution
**Zero-dependency S1 record pull (keyless, works for any ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scr
Line 54 tells the agent to run a Python DNS-over-HTTPS connector with user-supplied domain and selector arguments. The command supports legitimate DNS checks, but it still creates command-execution and input-validation risk.

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
    Credential handling for Resend automation
    Require a least-privilege RESEND_API_KEY, never print it, and explain where the connector sends requests.
  2. FIX-002
    Medium
    Optional connector command execution
    Document the exact reviewed connector scripts, validate domain and selector arguments, and require confirmation before running Python helpers.
  3. FIX-003
    Low
    Relative links trigger path traversal scanners
    Keep repository-relative links, but document that they are references, not file operations.

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Verify and export

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
