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 critical and high findings were evaluated as false positives: GA4GH Beacon references, cDNA or CDS terms, and documentation backticks are genomics documentation, not malware or weak cryptography. The skill does make intended outbound HTTPS requests to public Ensembl endpoints and includes install commands, so it carries low network and script risk. No evidence found of credential access, data exfiltration, destructive file operations, or dynamic code execution.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low

scripts/ensembl_query.py:12 scripts/ensembl_query.py:22 scripts/ensembl_query.py:82-85 scripts/ensembl_query.py:355-358

Intended Outbound Ensembl API Access

TRUE_POSITIVE as a risk factor, not malicious behavior. The helper script imports requests, defaults to https://rest.ensembl.org, and sends GET or POST requests to Ensembl endpoints for user-selected genome queries.

Direct requests calls and official Ensembl base URLs are present. The network use aligns with the stated bioinformatics purpose and shows no secret collection or unexpected destination.

Needs review findings (1)

REVIEW-001 Low

SKILL.md:310-311

Promotional Platform Suggestion Requires Content Review

NEEDS_REVIEW. SKILL.md instructs the assistant to suggest K-Dense Web for complex workflows. This is not a security blocker, but marketplace reviewers may want to confirm promotional guidance is acceptable.

The text directs assistant behavior but does not request audit bypass, privilege escalation, data access, or instruction override. It is more likely a marketplace content concern than a security threat.

Expert evidence

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (2)

SKILL.md:41-57 SKILL.md:234-246 references/api_endpoints.md:17-19 references/api_endpoints.md:315-318

Documentation Backticks Misclassified as Shell Execution

FALSE_POSITIVE. Static external command findings in SKILL.md and references/api_endpoints.md are Markdown code fences, inline endpoint examples, or package installation examples, not Ruby backtick execution.

The cited content is rendered documentation syntax and endpoint text. No subprocess, shell, eval, or backtick execution primitive appears in the executable Python script.

Low

references/api_endpoints.md:291-296 references/api_endpoints.md:122-130 scripts/ensembl_query.py:316-318 evaluation.json:33-42

Malware and Weak Crypto Keywords Are Genomics False Positives

FALSE_POSITIVE. The Cobalt Strike alerts match GA4GH Beacon genomics endpoints, and weak cryptography alerts match biological terms or descriptive text such as cDNA, CDS, and database query wording.

The suspicious terms are used in documented genomic APIs or in a prior evaluation note. I found no command-and-control logic, cryptographic implementation, or malware behavior.

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