Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds little beyond stating 'full details' without specifying what that includes (e.g., work notes, attachments) or any response format. No additional behavioral traits like permissions, rate limits, or side effects are disclosed, so the description does not add significant value over annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
