CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 1.00). The raw GitHub URL is a direct install.sh intended to be run via curl|bash (a high-risk delivery vector that can execute arbitrary code from an external repo), while supsub.net appears to be the project's domain and is not itself clearly malicious.

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/SupSub-AI/supsub-cli/master/scripts/install.sh | bash, which downloads and runs a remote script.
