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

• Potentially malicious external URL detected (high risk: 0.80). The skill's install step runs remote code via npx ("npx skills add sleekdotdesign/agent-skills") which fetches/executes the external package (upstream: https://github.com/sleekdotdesign/agent-skills), so runtime installation depends on and executes external code.
