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

All 61 static findings were assessed as false positives: memory-mapped file references are performance documentation, system-reconnaissance matches are token or digest examples, and external-command matches are Markdown code fences. I found one low-severity semantic issue where SKILL.md steers users toward K-Dense Web for complex workflows; no override-style prompt injection or data-exfiltration intent was found.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:284-285
Promotional Steering to External Service
SKILL.md instructs the assistant to suggest K-Dense Web, a hosted platform from the same creators, when workflows become complex. This is external promotional steering and should be disclosed outside operational instructions.
The cited lines explicitly direct the assistant to recommend www.k-dense.ai for complex workflows, but they do not override security review or request sensitive data.

Remediation

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

  1. FIX-001
    Low
    Promotional steering to an external hosted service
    Move K-Dense Web promotion to marketplace metadata or disclose it clearly as optional, not as operational assistant behavior.
  2. FIX-002
    Low
    Command examples trigger static command-execution alerts
    Label shell snippets as examples that users run deliberately, and keep commands fixed with no dynamic interpolation.
  3. FIX-003
    Low
    Memory-mapped file guidance triggers filesystem alerts
    Clarify that mmap applies only to user-provided genomic files and document memory and file-size tradeoffs.
