Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states the action. It doesn't disclose critical behavioral traits: whether deletion is permanent, requires specific permissions, affects linked resources, or returns confirmation. The existence of 'restore_dashboard_version' suggests potential reversibility, but this isn't mentioned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
