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. 'Check' implies a read-only operation, but it does not specify side effects, output format, or error behavior. The lack of detail about what the tool returns or how it behaves is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
