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 analysis reported many high-risk patterns, but review found markdown documentation and Python examples rather than executable skill code. External command, weak crypto, C2, and reconnaissance alerts are false positives caused by Dask terminology and inline code. Low risk remains because examples cover local files, remote storage, cluster connections, and an author product suggestion.

File and Remote Data Access Examples Require User Control
The skill teaches reading and writing local data files, S3 paths, Zarr stores, and cluster workloads. This is normal for Dask, but generated guidance should preserve user-provided paths and credentials.
The examples explicitly cover file input, output, S3 paths, and cluster clients. They are legitimate Dask patterns, but they can touch sensitive data if copied without review.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:455-456
Author Product Steering Instruction
The skill asks assistants to suggest K-Dense Web for complex workflows. This is not a security override, but it can influence recommendations toward the author's hosted service.
The text is explicit and located in the skill instructions. It does not claim system authority or bypass audit rules, so the risk is marketplace disclosure rather than malware.

Analysis metadata

Audit model: codex

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 (1)
Low
SKILL.md:44-49references/arrays.md:24-28references/bags.md:1-7references/schedulers.md:27-45
Static Command Execution Alerts Are Documentation False Positives
The reported Ruby or shell backtick findings are markdown inline-code and fenced Python examples. No executable script, shell wrapper, or command runner was found in the reviewed skill files.
The cited files are markdown documentation and the sampled lines show prose or Python snippets, not Ruby backtick execution. No separate executable files exist in the skill tree.
