Risk Level: LOW
Scan Summary

The skill's SKILL.md is mostly clear, but carries one notable transparency concern: it references remote script execution without establishing a review boundary, which weakens the ability to fully audit what the agent will actually run. Instruction/data separation looks reasonable, and the scan did not surface strong prompt-injection vectors. However, behavior analysis was not run, so it's not possible to confirm whether loading this skill materially changes downstream behavior compared to a no-skill baseline—this gap, combined with the unreviewed remote execution path, supports the AT_RISK verdict. Confidence is medium because finite testing passed on injection risk, but the missing behavior analysis and the opaque remote execution leave meaningful uncertainty unresolved.
