Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is a non-read-only, non-idempotent, non-destructive operation. The description adds valuable context beyond these hints by stating it 'Creates a separate production Neo4j instance with its own credentials and database' and 'Requires paid plan,' disclosing side effects and prerequisites.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
