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. It only states 'Get information,' which implies a read operation, but does not disclose any potential side effects, authentication requirements, rate limits, or return format peculiarities. This is minimal beyond what the tool name already conveys.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
