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 includes examples that fetch and execute remote code at runtime (e.g., the CDN/ESM imports "https://cdn.jsdelivr.net/npm/mermaid@latest/dist/mermaid.min.js" and "https://cdn.jsdelivr.net/npm/mermaid@latest/dist/mermaid.esm.min.mjs", the dynamic import "https://esm.run/@iconify-json/logos", and pulling/running the Docker image "ghcr.io/mermaid-js/mermaid-cli/mermaid-cli"), which are runtime external dependencies that execute remote code.
