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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs using WebFetch at runtime to load external instruction/specification documents (e.g., https://modelcontextprotocol.io/llms-full.txt and https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md and https://raw.githubusercontent.com/modelcontextprotocol/typescript-sdk/main/README.md), which the agent would ingest to determine behavior and implementation guidance, so these fetched resources directly control prompts/instructions and are required dependencies.
