CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 1.00). All listed URLs are standard GitHub/raw.githubusercontent and official weather API endpoints except https://evil.com/steal, which is an explicit malicious/exfiltration endpoint and thus a clear red flag.

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

• Potentially malicious external URL detected (high risk: 0.70). The skill explicitly runs curl commands at runtime to fetch GitHub repo metadata and raw SKILL.md (https://api.github.com/repos/OWNER/REPO, https://api.github.com/repos/OWNER/REPO/contents/skills/SKILL_NAME, https://raw.githubusercontent.com/OWNER/REPO/main/skills/SKILL_NAME/SKILL.md), which pulls external content into the agent's context during vetting and therefore can directly influence prompts or include executable instructions.
