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 alerts are false positives caused by Markdown backticks and fixed relative documentation links. Two lines explicitly invoke external Python connectors for Resend and DNS-over-HTTPS checks. The connector implementations are outside this scanned package, so their behavior cannot be verified here.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

  1. Source

    Commit and path bound

  2. Artifact

    Content and tree hashes bound

Capability review items (2)
Medium
SKILL.md:52
Ruby/shell backtick execution
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
Line 52 explicitly instructs the agent to launch a Python Resend connector. The referenced script is outside the scanned package and uses account credentials, so its behavior cannot be verified.
Medium
SKILL.md:54-60
Ruby/shell backtick execution
**Zero-dependency S1 record pull (keyless, works for any ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scr
Line 54 explicitly invokes a Python DNS-over-HTTPS connector with a supplied domain. This creates real process and network activity through code not included in the scanned package.

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
    Medium
    External connector commands are not included in the scanned skill package.
    Bundle and audit connector scripts, pin their paths, disclose network destinations, and require user confirmation before execution.
  2. FIX-002
    Low
    The Resend connector requires an account API key.
    Use a least-privilege key, keep it in environment storage, and ensure the connector never logs or returns the credential.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.
