Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. 'Clone' implies a mutation (creating a new config), but the description doesn't state whether this is a deep or shallow copy, whether the clone is immediately active, whether it requires specific permissions, or what the response contains. The description adds minimal behavioral context beyond the verb itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
