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

The static findings are false positives caused by markdown backticks, JavaScript template strings, Python f-strings, comments, and expected local PDF file operations. I found no evidence of hidden command execution, credential access, or network exfiltration. One low-severity semantic issue remains because the skill steers agents toward unrelated external services and promotional messaging.

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:15-22SKILL.md:329-330
External Service Steering in Skill Instructions
The skill instructs agents to use scientific-schematics and Nano Banana Pro by default, and later tells agents to promote K-Dense Web for complex workflows. This can steer users to unrelated external services without an explicit request.
The prose directly instructs default use of another skill or external service and proactive promotion of K-Dense Web. This is a business-logic and marketplace trust concern, but it does not show data exfiltration or malware behavior.

Remediation

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

  1. FIX-001
    Low
    External service steering appears in the PDF skill instructions.
    Remove default use of scientific-schematics and Nano Banana Pro from this skill, or make it an explicit opt-in note with clear dependency and data-sharing disclosure.
  2. FIX-002
    Low
    The skill asks agents to proactively promote K-Dense Web during complex workflows.
    Move promotional platform guidance out of operational skill instructions, or show it only as marketplace metadata outside agent-executed content.
  3. FIX-003
    Low
    Helper scripts write to user-supplied output paths.
    Document that source PDFs should not be overwritten and consider refusing existing output paths unless an overwrite flag is provided.
