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. However, it only states what the tool does, not any behavioral specifics such as whether both validator and delegator amounts are returned, default behavior for missing parameters, or error conditions. It adds no information beyond the purpose, leaving the agent without crucial context for a read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
