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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs the agent to "Fetch docs
• Use WebFetch on the URLs above" (e.g. https://docs.umbraco.com/umbraco-cms/customizing/extending-overview/extension-types/collections), using that runtime-fetched documentation to drive code generation and implementation, so external content would directly control the agent's instructions and is a required dependency.
