MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The install script fetches and executes remote content at runtime — it downloads the yt-dlp binary from https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp and pipes the astral.sh installer (https://astral.sh/uv/install.sh) to sh, which executes remote code.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 0.90). The skill explicitly instructs installing system packages using apt/dnf (with sudo), writing to /usr/local/bin, and editing /etc/ImageMagick-6/policy.xml — all actions that modify system state and require elevated privileges.
