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.

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

Most static findings are false positives from Markdown code formatting and relative documentation links. Two documented helper invocations execute unreviewed connector scripts, and one helper receives RESEND_API_KEY; these require verification and explicit user confirmation before use.

Capability review items (3)
High
SKILL.md:52
Generic API/secret keys
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
The Resend connector is explicitly invoked with access to RESEND_API_KEY. Secret access by an unreviewed external helper presents a credential-exposure risk.
Medium
SKILL.md:52
Ruby/shell backtick execution
**Zero-dependency ESP automation (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts
The skill instructs the host to execute a Python connector located under CLAUDE_PLUGIN_ROOT. The connector source is outside the two scanned files, so its behavior cannot be verified before it receives account access.
Medium
SKILL.md:54
Ruby/shell backtick execution
**Zero-dependency S1 record pull (keyless, works for any ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scr
The skill instructs the host to run an external DNS-over-HTTPS connector with a supplied domain argument. The connector source is not in the scanned files, so input handling and network behavior cannot be verified.

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
    Unreviewed Resend connector execution with RESEND_API_KEY
    Include the connector source in the skill package, document its exact API calls, and require explicit confirmation before running it or accessing the key.
  2. FIX-002
    Medium
    Unreviewed DNS-over-HTTPS connector execution
    Include and review the connector source, validate the domain argument, and disclose the DNS-over-HTTPS endpoint before execution.
  3. FIX-003
    Medium
    Automatic helper execution instructions
    State that users must approve each connector command and review its inputs before it runs.
