Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only states 'list', implying a read operation, but does not disclose any behavioral traits such as permission requirements, pagination, rate limits, or what happens if the database does not exist. The description adds minimal value beyond the verb.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
