Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, indicating a safe read operation. The description adds that it returns an overview of invites, paper, and planning progress, but does not disclose additional behavioral traits such as response format or data freshness. With annotations covering read safety, the description provides adequate but not rich context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
