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 but offers no information beyond the basic action. It doesn't describe whether this is a read-only operation, what data format is returned, if there are rate limits, authentication needs, or any side effects, making it inadequate for a tool with potential complexity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
