Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only implies a read operation via 'Get' but does not address authentication needs, rate limits, data freshness, or whether the data is aggregated in real-time. This lack of detail limits the agent's understanding of the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
