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

• Potentially malicious external URL detected (high risk: 0.90). The SKILL.md includes a runtime installation command that fetches and executes remote code via curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh (the Homebrew installer), which the agent may run to install ffmpeg and thus executes external code at runtime.

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 explicitly tells the agent it can check/install ffmpeg itself (including running brew and sudo apt/dnf commands and even the Homebrew curl|bash installer), which asks the agent to modify the host system and run privileged package-install commands.
