CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.80). Astral.sh's install.sh is a direct "curl | sh" install script from a third‑party domain (high risk unless you verify the script contents/signature), while upscayl.org is the official Upscayl site and is low risk — treat the astral.sh link as suspicious.

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

• Potentially malicious external URL detected (high risk: 0.90). The install procedure proposes running a runtime command that fetches and executes remote code ("curl -LsSf https://astral.sh/uv/install.sh | sh") to install the required uv prerequisite, so the skill would download and run external code that directly affects execution.

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

• Attempt to modify system services in skill instructions detected (high risk: 0.90). The prompt explicitly stages and recommends running privileged system package commands (e.g., "sudo apt install", "brew install"), proposes piping a remote installer via curl|sh, and instructs the agent to guide or run system-level installs that modify the host environment, so it pushes the agent to change the machine state and require elevated privileges.
