Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It discloses the core read-only behavior via 'List' and mentions optional filtering, but it does not state the workspace default scoping behavior, the response shape, or category matching semantics. The description is not misleading, but it leaves several behavioral details unspoken.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
