Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It accurately states the tool lists presentations with export history, implying a read-only operation. However, it does not mention whether the list is ordered, paginated, or if it counts items. The simplicity of zero parameters reduces need, but some additional context (e.g., 'returns presentation IDs') would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
