Risk Level: MEDIUM
Full Analysis
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The bootstrap scripts run at first use and fetch+execute remote installers/artifacts—e.g., the macOS/Linux script runs /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" and both bootstrap scripts download the PlantUML JAR via https://github.com/plantuml/plantuml/releases/latest/download/plantuml.jar which may be executed—so the skill performs runtime downloads that execute remote code.
MEDIUM W013: Attempt to modify system services in skill instructions.
- Attempt to modify system services in skill instructions detected (high risk: 0.80). The skill’s bootstrap and setup steps instruct installing system-wide packages (Python, Java, PlantUML) via package managers and explicitly advises bypassing PowerShell execution policy, which encourages privileged installs and a security bypass on the host.
