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 specify whether this returns real-time data, cached data, or requires specific permissions. It also doesn't describe the return format, data structure, or any limitations like rate limits or availability constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
