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

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

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

Static analysis reported many severe patterns, but contextual review found them in Markdown documentation, examples, relative links, and placeholder configuration. No confirmed malicious intent, credential exfiltration, prompt-injection attempt, or runnable hidden behavior was found. The main residual risk is that users may copy example commands, network calls, or environment variable handling without adapting them safely.

Remediation

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

  1. FIX-001
    Low
    Example commands may be copied into real projects without review.
    State that scaffold, install, deploy, and development commands should be run only after the user confirms the target directory and package source.
  2. FIX-002
    Low
    Configuration examples include placeholder secrets and connection strings.
    Keep all values as placeholders and remind users to use secret managers or environment-specific configuration for production.
  3. FIX-003
    Low
    API examples show external network requests.
    Add a short note that production integrations should validate user input, handle rate limits, and avoid logging tokens or secrets.
