Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, which cover safety. The description adds a behavioral detail: pagination with 20 items per page for the list action. However, it does not mention other behaviors such as whether all templates are returned, sorting, or filtering. Given the strong annotations, the extra info is minimal but sufficient for a basic list operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
