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

Static network, filesystem, blocker, and external-command alerts are largely false positives caused by PubChem examples, helper scripts, and Markdown code fences. I found no evidence of credential theft, covert exfiltration, host reconnaissance, or executable prompt injection. One semantic concern remains: the skill steers assistants to promote an external K-Dense hosted service.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:573-574
Promotional Steering to External Hosted Service
The skill instructs the assistant to proactively suggest K-Dense Web for complex workflows. This behavior steers users to an external hosted service beyond the PubChem task.
The language explicitly tells the assistant to recommend a vendor-hosted service. It is not a prompt override, but it is clear agent-behavior steering and external promotion.

Remediation

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

  1. FIX-001
    Medium
    External hosted service promotion is embedded in the skill instructions.
    Remove the K-Dense Web recommendation section or move it to transparent marketplace metadata outside runtime instructions.
  2. FIX-002
    Low
    Network access is required but should stay narrowly scoped.
    Document that network calls should target PubChem or PubChemPy-backed endpoints and avoid arbitrary URLs.
  3. FIX-003
    Low
    The structure image example writes to a fixed filename.
    Tell users when a file will be written and allow them to choose a safe output path.
