Installation context

Historical evidence

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

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

Static analysis reported many high and medium findings, but review shows the weak cryptography and external command detections are false positives from Markdown, scientific terms, and Python examples. The real risks are limited to local script execution, local filesystem writes, documentation links, and a promotional instruction to suggest the author's hosted web product.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low

SKILL.md:385-386

Promotional Hosted-Service Suggestion

The skill asks the assistant to proactively suggest K-Dense Web for complex workflows. This is not malware, but it can steer users toward an external hosted product and should be disclosed or removed before marketplace publication.

The instruction is explicit and appears in the skill guidance. It is a marketplace trust concern, but it does not claim system authority or bypass security controls.

Expert evidence

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

Local Filesystem Writes in Analysis Scripts

The bundled scripts create a figures directory and write processed AnnData, metadata, and marker outputs. These writes are expected for a local scientific analysis workflow and do not show exfiltration or destructive behavior.

The file operations are limited to creating output directories and saving user analysis artifacts. No deletion, hidden path traversal, or remote transfer is present in the reviewed lines.

Low

SKILL.md:95-98 references/api_reference.md:7-24 references/standard_workflow.md:9-22

Markdown Code Fences Flagged as External Commands

The external-command findings are Markdown backticks around Python examples and Scanpy API snippets. No shell execution primitive, subprocess call, or command interpolation was found in the referenced documentation context.

The cited content is fenced Python or Markdown inline formatting. The scripts reviewed do not contain subprocess, shell, or backtick execution semantics.

Low

assets/analysis_template.py:5 references/api_reference.md:222 scripts/qc_analysis.py:139 SKILL.md:3

Weak Cryptography Detections Are Textual False Positives

Static high findings for weak cryptography do not correspond to cryptographic API calls. The cited lines contain prose, argparse setup, or AnnData field names, not MD5, SHA1, DES, RC4, or password hashing logic.

The reviewed locations do not perform cryptographic operations. The matches appear to be substring or terminology collisions in ordinary Scanpy documentation.

Low

SKILL.md:370-372

Documentation URLs Are Non-Executable References

The hardcoded URLs point to Scanpy, Scanpy tutorials, and scverse documentation. They are references in Markdown and are not used by code to fetch data or send user information.

The URLs are listed under additional resources. No network client, HTTP request, or credential-bearing request is present in the reviewed content.

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
