CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). These URLs include direct raw script downloads (shell + PowerShell with irm | iex) and a direct GitHub release binary URL — common high-risk channels for distributing malware if the source is untrusted or compromised.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill’s runtime runner script (scripts/run.sh) fetches and executes remote releases — it calls curl on "https://api.github.com/repos/${REPO}/releases/latest" to discover a release and then downloads/extracts "https://github.com/${REPO}/releases/download/${LATEST}/skillshare_${VERSION}_${OS}_${ARCH}.tar.gz", which downloads and installs remote code at runtime.
