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 behavior. It only restates the tool's purpose without adding details like pagination, ordering, permissions, or response format. The term 'list' implies a read operation, but no additional context is given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
