Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description bears the full burden of behavioral disclosure. It only states the basic function without revealing any behavioral traits, such as what constitutes a barcode object, whether the list is filtered, or any side effects. This is insufficient for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
