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

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

Potentially malicious external URL detected (high risk: 1.00). The skill explicitly uses Cloudflare's MCP server at https://mcp.cloudflare.com/mcp at runtime (via claude mcp / the MCP's search()/execute() tools) to submit and execute generated JavaScript against the Cloudflare API, so this external URL is used to execute remote code that directly controls the agent's actions.
