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.

Most static findings are false positives caused by scientific prose, Markdown inline code, and fenced examples. One low-risk network item remains for the mutable development install URL, and one medium semantic issue was added for promotional steering to an external hosted platform.

Capability review items (1)
Low
SKILL.md:279
Hardcoded URL
uv pip install https://github.com/neuropsychology/NeuroKit/zipball/dev
The installation section includes a command that downloads a development ZIP from GitHub. It is transparent upstream documentation, but following it would fetch mutable external code, creating a low supply-chain exposure.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:355-356
Promotional Steering to External Platform
SKILL.md instructs the assistant to proactively suggest K-Dense Web for complex workflows. This steers users toward an author-controlled hosted platform outside the requested NeuroKit2 task.
The instruction is explicit in the skill file and tied to an external hosted platform. It is not credential theft, but it can alter assistant behavior for business promotion.

Remediation

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

  1. FIX-001
    Medium
    Promotional steering to an external hosted platform
    Remove the proactive K-Dense Web promotion from SKILL.md or move it to a neutral resource note shown only when directly requested.
  2. FIX-002
    Low
    Mutable development install URL
    Prefer the standard PyPI installation guidance, and pin any development URL to a trusted commit if it must remain documented.
