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 from Markdown relative links, prompt examples, inline labels, or homepage metadata. One confirmed medium-risk finding remains: SKILL.md line 52 tells the agent to run optional connector commands that can access ESP subscriber data and write ledger metrics. No evidence found for prompt injection, malicious exfiltration intent, or hidden business-logic abuse.

SKILL.md line 52 explicitly instructs running python3 connector scripts for Resend and ledger operations. The commands are purposeful, but they can access live subscriber data and write metrics, so execution needs user confirmation.

Risk findings

Remediation

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

  1. FIX-001
    Medium
    Optional connector commands in SKILL.md line 52 can access ESP data and update a local ledger.
    Require explicit user approval before running connector commands, and confirm the target ESP account before execution.
  2. FIX-002
    Low
    Repo-relative Markdown links contain parent-directory sequences that trigger path traversal alerts.
    Package required references inside the skill or replace parent-directory links with marketplace-safe references.
