Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. The verb 'Get' implies a non-destructive read, which is the key behavioral trait, but the description does not disclose return format, ordering, or whether statuses are global to the Redmine instance or scoped to a specific project. This is adequate but thin for a simple enumeration tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
