promptfoo

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

• Potentially malicious external URL detected (high risk: 0.80). The skill invokes "npm install -g promptfoo" / "npx promptfoo@latest", which fetches and executes the promptfoo package from the npm registry (e.g. https://registry.npmjs.org/promptfoo) at runtime, so remote code is downloaded and executed as a required dependency.
