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

• Potentially malicious external URL detected (high risk: 0.80). The skill's validation steps require running "npx skillcheck" and "npx agnix", which will fetch and execute packages from the npm registry (e.g., https://www.npmjs.com/package/skillcheck and https://www.npmjs.com/package/agnix), so remote code is executed at runtime and is a required dependency for the skill's validation; therefore this is a runtime external dependency that can execute code.
