Finding
The skill declares no permissions, yet its documented functionality and metadata clearly rely on outbound network access to Yahoo Finance. This permission mismatch is a real security issue because it hides the skill's actual capabilities from reviewers and policy enforcement, reducing transparency and making it easier for network-enabled behavior to bypass expected controls.
