Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the burden of disclosing behavior. 'Get all' indicates a read-only operation, which is transparent. However, it does not mention whether results are paginated, ordered, or limited, which could be relevant for a list tool. Overall, it covers the basic behavior but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
