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.

The skill contains legitimate instructions to run npx commands from SKILL.md, including package execution and Playwright setup. Several static hits are markdown code fences or inline file names and are false positives for Ruby backtick execution. No prompt injection or malicious data exfiltration intent was found in the reviewed files.

Observed in 11 evidence locations

Capability review items (3)
Medium
SKILL.md:28-31
Ruby/shell backtick execution
```bash
This block instructs the agent to run npx commands, including installing Chromium and executing an npm package. The commands are task-related, but they still run external code and can download dependencies.
Medium
SKILL.md:41-43
Ruby/shell backtick execution
```bash
This block instructs the agent to run npx extract-design-system with a user-provided public URL. It is a legitimate workflow command, but it executes an external package against third-party input.
Medium
SKILL.md:47-49
Ruby/shell backtick execution
```bash
This block instructs the agent to run npx extract-design-system init. The command is narrowly scoped, but it still executes an npm package in the user's project.

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 package execution
    Pin the extract-design-system package version in examples and require user confirmation before running npm-hosted code.
  2. FIX-002
    Low
    Browser binary installation
    Explain that Playwright may download Chromium and prefer an existing local browser installation when available.
