Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide no hints (all false), so the description carries the full burden. It reveals that the description is the matching goal, that AI suggestions are off by default and can be enabled, that the user confirms/rejects suggestions, that the title auto-generates, and that it returns a list_id. This is rich behavioral context beyond what annotations or schema convey, and nothing contradicts the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
