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 CloudFormation constructs that fetch external templates/snippets at deployment time—e.g., TemplateURL: https://s3.amazonaws.com/my-bucket/network.yaml and https://s3.amazonaws.com/my-bucket/compute.yaml and AWS::Include Location: s3://my-bucket/snippet.yaml—which CloudFormation retrieves at runtime and directly controls the resources/code that will be executed, making them required runtime dependencies.
