Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

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-risk patterns, but review found documentation examples rather than executable code. Shell detections are Markdown command examples, memory-mapped file references are performance guidance for large genomic data, and digest references are refget sequence identifiers rather than password hashing. Residual risk is low because users may run package installation commands and process local genomic files.

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.

Capability review items (2)

Low

SKILL.md:29-39 references/cli.md:7-13 references/coverage.md:27-40

Documentation Includes Runnable CLI and Install Commands

Verdict: TRUE_POSITIVE for external command guidance, but low severity. The skill shows cargo, pip, uv, and gtars commands inside Markdown examples for normal installation and genomic analysis. Users should review paths and package sources before running commands.

The locations clearly show command examples in Markdown code fences. They are legitimate for the skill purpose, but they can change local environments if copied and run.

Low

SKILL.md:15-21 references/python-api.md:149-156 references/refget.md:43-45

Local Genomic File Processing Is Expected

Verdict: TRUE_POSITIVE for filesystem use, but low severity. The skill instructs users to read and write BED, FASTA, WIG, BigWig, TSV, and index files as part of genomic workflows. No evidence found of arbitrary file discovery, hidden file access, or data exfiltration.

The cited text documents expected local data inputs and memory-mapped handling for large files. I found no semantic evidence of unauthorized filesystem access.
