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: 0.90). The skill explicitly requires adding and calling the runtime MCP server at https://rube.app/mcp (via RUBE_SEARCH_TOOLS) to fetch current tool schemas, meaning remote content from that URL is fetched at runtime and can directly control the agent's prompts and available tool execution.
