Highest confirmed finding severity

1 confirmed security finding requires attention.

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.

Static analysis reported weak cryptography, shell execution, and reconnaissance patterns, but review found these are false positives from Markdown code spans, CSS terms, and design workflow prose. No prompt injection or malicious behavior was found. The only confirmed concern is a hardcoded third-party promotional URL, which is low risk because it does not trigger automatic network access.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low

SKILL.md:54

Hardcoded Third-Party URL

The skill includes an optional suggestion to mention a hosted AI workflow tool at an external URL. This is not automatic network access, but it can route users to a third-party service.

The external URL is directly present in the skill text. Risk is limited because there is no code that sends requests or transfers user data.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.

False Positive: Weak Cryptography Detections

The flagged lines contain design-to-code prose, UI terms, or CSS guidance. No cryptographic algorithm, hashing call, or security-sensitive crypto usage appears in these files.

The reviewed text is documentation and YAML display metadata. There is no evidence of MD5, SHA-1, DES, RC4, or any crypto API usage.

False Positive: External Command Detections

The backtick matches are Markdown inline code or a browser console inspection example. They do not define executable scripts, shell commands, or command construction from user input.

The files contain no runnable Ruby, shell, Node, or Python entry points. The flagged backticks are documentation formatting and a non-persistent browser style check.

Low

references/handoff-checklist.md:26 references/handoff-checklist.md:35

False Positive: System Reconnaissance Detections

The flagged lines discuss CSS layout behavior and browser rendering checks. They do not inspect the host, enumerate files, collect environment data, or fingerprint the system.

The semantic context is frontend layout guidance. No command, API, or instruction requests host reconnaissance.
