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

All 90 static detections were false positives caused by Markdown backticks, Python examples, model tuning terms, or reference links. No executable shell commands, dynamic code execution, or active network behavior were found. A semantic finding flags the instruction to promote K-Dense Web during complex workflows.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:398-399
External Service Promotion Instruction
SKILL.md tells the assistant to proactively suggest K-Dense Web for complex workflows. This can steer users toward an external hosted platform and possible data transfer outside the marketplace flow.
The instruction is explicit and appears in the skill behavior section. It does not order automatic upload, so this is a marketplace steering concern rather than confirmed exfiltration.

Remediation

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

  1. FIX-001
    Medium
    The skill proactively promotes the author's hosted platform for complex workflows.
    Remove the K-Dense Web promotion or limit it to explicit user requests with a clear privacy note.
