Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Get' implies a read operation, but the description doesn't address whether this requires authentication, what format the properties are returned in, whether there are rate limits, or if this retrieves property definitions versus property values. For a tool with 2 parameters and no annotation coverage, this is insufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
