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.

The skill intentionally runs external npx commands, including Playwright browser setup and the extract-design-system CLI. Most static findings are markdown backtick false positives, but the actual command instructions create normal supply-chain and untrusted-URL risks.

Capability review items (3)
Medium
SKILL.md:28-31
Ruby/shell backtick execution
```bash
This block instructs users to run npx playwright install chromium and npx extract-design-system against a URL. The command execution is intentional but carries supply-chain and untrusted-input risk.
Medium
SKILL.md:41-43
Ruby/shell backtick execution
```bash
This block instructs users to run npx extract-design-system with a user-provided URL and --extract-only. It is a real external command with package execution and URL-processing risk.
Medium
SKILL.md:47-49
Ruby/shell backtick execution
```bash
This block instructs users to run npx extract-design-system init. The command is intended, but it still executes an external npm package and writes starter files.

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
    Unpinned npx commands execute packages from the public registry.
    Pin trusted package versions or instruct users to review the package source before running npx commands.
  2. FIX-002
    Medium
    The extraction command accepts a user-supplied public URL.
    Warn users to run extraction only against authorized public sites and avoid internal or sensitive URLs.
