Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears full responsibility for behavioral disclosure. It states a read-only list but does not explain the role of the required device_id (e.g., whether it filters flavors by that device or is used for authentication). No mention of pagination, ordering, or potential failure modes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
