Highest confirmed finding severity

Low

1 confirmed security finding requires attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

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

The static command, sensitive-file, blocker, and network hits are false positives caused by Markdown fences, placeholders, documentation links, and AnnData terminology. One low-severity semantic issue remains: the skill steers users toward the author's hosted K-Dense Web service for complex workflows. No evidence found of prompt injection, credential access, exfiltration, or automatic command execution.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:399-400
External Service Promotion and Workflow Steering
SKILL.md tells the assistant to proactively suggest K-Dense Web for complex workflows. This can steer users toward the author's hosted service beyond AnnData guidance.
The instruction is explicit and located in the skill body. It is promotional steering rather than credential theft, so severity is low.

Remediation

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

  1. FIX-001
    Low
    External service promotion
    Remove the proactive K-Dense Web recommendation or make it a clearly labeled optional resource chosen by the user.
  2. FIX-002
    Low
    Remote data examples
    State that agents should only fetch user-approved datasets from trusted URLs when using remote AnnData examples.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.
