Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Check the current Skill page

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

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

Most execution and reconnaissance detections are false positives from Markdown fences, inline file names, CSS, comments, and JavaScript RegExp.exec. The real risks are external CDN and font loads in generated artifacts, plus a trust risk from a community skill requiring Anthropic-branded output.

Report position

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (5)
Low
Hardcoded URL
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.7.0/p5.min.js"></script>
The instructions require generated HTML to load p5.js from cdnjs. This creates an external browser dependency and supply-chain risk.
Low
Hardcoded URL
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/1.7.0/p5.min.js"></script>
The viewer template loads p5.js from cdnjs at runtime. That external request is a real dependency even if the source is a common public CDN.
Low
Hardcoded URL
<link rel="preconnect" href="https://fonts.googleapis.com">
The template preconnects to Google Fonts. This creates an external browser connection and exposes basic request metadata.
Low
Hardcoded URL
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
The template preconnects to fonts.gstatic.com. This is a real third-party network dependency for generated artifacts.
Low
Hardcoded URL
<link href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;500;600&family=Lora:wght@400;5
The template loads CSS from Google Fonts. That external font request is legitimate but still carries privacy and availability risk.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Medium
Community Skill Requires Anthropic-Branded Output
The community skill repeatedly directs generated artifacts to keep Anthropic branding, including fixed colors, fonts, and layout. This can make generated outputs appear officially affiliated when the source is a third-party skill.
The branding instructions are explicit in SKILL.md and viewer.html. The risk is trust and attribution confusion rather than code execution.

Remediation

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

  1. FIX-001
    Medium
    Anthropic branding in community-generated artifacts
    Replace mandatory Anthropic branding with neutral styling or require clear attribution that the artifact is user-generated and not official.
  2. FIX-002
    Low
    External CDN and font dependencies
    Vendor p5.js and fonts with the skill or clearly disclose that generated artifacts load cdnjs and Google Fonts.

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Verify and export

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
