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, but it only states a 'get' operation without clarifying whether it reads from local storage, fetches via network, or requires any specific state (e.g., an open session). It does not describe side effects, performance implications, or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
