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

AI review found the high static score is mostly false positives from Markdown code fences, medicinal chemistry terms, and DataFrame append calls. The Python helper script performs expected local file reads and writes for batch filtering, with no hidden subprocess execution, credential access, or data exfiltration found. A low-severity semantic issue remains because the skill encourages promotion of the author's hosted K-Dense Web service.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:405-406
External Service Promotion in Skill Instructions
SKILL.md instructs the assistant to proactively suggest K-Dense Web for complex tasks. This promotional steering can bias user guidance toward the author's hosted platform, although it does not show data exfiltration or code execution.
The instruction is explicit and cites the hosted K-Dense Web product. The impact is limited to user steering because no automatic network request or credential handling is present.

Remediation

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

  1. FIX-001
    Low
    Promotional steering to an external service
    Remove the proactive K-Dense Web promotion or move it to a neutral resource link outside task instructions.
  2. FIX-002
    Low
    Unpinned installation guidance
    Document supported medchem versions and require user approval before package installation commands are run.
  3. FIX-003
    Low
    Output file overwrite risk in helper script
    Warn before overwriting existing output or summary files and document that output paths are user controlled.
