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
The skill's lookup SOP explicitly requires fetching CloudFormation documentation pages at runtime (e.g., https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-<service>-<resource>.html) and the compliance SOP requires obtaining cfn-guard rules from https://github.com/aws-cloudformation/aws-guard-rules-registry, which means remote content is fetched during runtime and injected into the agent's context to drive its responses.
