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 command, network, script, and blocker patterns, but most reviewed hits are false positives from Markdown backticks, RBS syntax examples, and reference Zeitwerk source. The skill is publishable with a medium warning because its validation workflow instructs the agent to run local Ruby tooling and to edit Ruby source files.

Local Ruby Tool Execution During Validation

The skill instructs agents to run rbs-inline, rbs validate, and steep check during validation. These are legitimate Ruby typing commands, but they execute local project tooling and dependencies, so users should review the project before running them.

The command instructions are explicit and semantically confirmed in the validation workflow. Risk is moderated because the commands are standard project-local Ruby typing tools, not hidden exfiltration or arbitrary shell construction.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low

Reference Ruby Files Trigger Static Patterns

Several flagged script and reconnaissance patterns occur in bundled Zeitwerk reference examples, including require wrapping, path expansion, glob expansion, and autoload management. These files are examples for annotation style, not install hooks or skill-executed scripts.

The code is real Ruby, but it is located under reference examples and there is no evidence that the skill runs it. The behavior matches normal Zeitwerk loader internals rather than marketplace malicious intent.

Expert evidence

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

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

Markdown Syntax Misclassified as Command Execution

Many external command and blocker hits are caused by Markdown inline backticks, fenced Ruby examples, and RBS syntax documentation. Reviewed examples describe annotations and generated type signatures rather than shell execution.

The cited lines are documentation and code fences, not executable skill code. The static pattern is explainable by backticks and Ruby examples in Markdown.

Hardcoded URLs Are Documentation Sources

The hardcoded URL findings point to upstream documentation and example source references. No evidence found that the skill sends data to those URLs or performs network requests.

The URLs are plainly labeled as source references. I found no fetch logic, credential handling, or exfiltration flow tied to them.

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