Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full behavioral disclosure burden. It fails to state that this is a read-only operation, what it returns, or any permissions or side effects. 'Get' weakly implies read-only, but no substantive behavior is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
