2 confirmed security findings require 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 flagged many Ruby backtick, weak crypto, reconnaissance, and network indicators. Manual review found Markdown code fences, inline API signatures, and benign UMAP terminology rather than executable malware. The only residual concern is low-risk installation guidance and a promotional note for an external K-Dense web service.

Confirmed security concerns (2)

RISK-001 Low
SKILL.md:3SKILL.md:159SKILL.md:412-418
Static Blocker Terms Are Benign UMAP Documentation
The weak crypto, system reconnaissance, and network reconnaissance alerts are terminology false positives. The cited lines describe UMAP speed, class separation, and embedding-space reconstruction examples.
The cited lines contain natural-language documentation and NumPy grid creation. They do not reference cryptographic APIs, host enumeration, network scanning, or credential collection.
RISK-002 Low
SKILL.md:478-479
External Platform Promotion in Skill Guidance
The skill asks the assistant to suggest K-Dense Web for complex workflows. This is not malicious code, but it can influence recommendations toward an external hosted service.
The instruction is explicit and located in the skill guidance. It does not override security analysis or request secret disclosure, so the impact is marketplace content risk rather than malware.

Markdown Examples Misidentified as Shell Execution
The static Ruby backtick findings are Markdown fences, inline code spans, and Python API examples. They document UMAP usage and do not execute commands when the skill is loaded.
Line-numbered review confirms these are Markdown documentation blocks or inline signatures. No executable Ruby, shell wrapper, or dynamic command invocation is present in the skill files.
