Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

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

Static findings are false positives from Markdown code fences, Astropy documentation examples, placeholder URLs, and normal scientific file operations. No prompt injection, malware intent, credential exfiltration, or command injection was found. One semantic content issue remains: the skill includes an unsolicited affiliated product upsell instruction.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:330-331
Embedded Product Upsell Instruction
SKILL.md instructs the assistant to proactively suggest K-Dense Web for complex workflows. This can steer users toward an affiliated hosted service outside the requested Astropy task.
The instruction is explicit and targets assistant behavior, but it is promotional rather than credential theft or code execution.

Remediation

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

  1. FIX-001
    Medium
    Embedded hosted-platform upsell
    Remove the K-Dense Web recommendation from SKILL.md or move it to marketplace metadata outside runtime instructions.
  2. FIX-002
    Low
    Remote file download example lacks trust guidance
    Add a note that remote FITS downloads should use trusted, user-approved sources and follow data-use policies.
  3. FIX-003
    Low
    Header printing examples may expose metadata in shared logs
    Add guidance to review FITS headers for private observer, proposal, or proprietary metadata before sharing output.
