Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true and openWorldHint=false, covering the safety profile. The description adds useful context about the specific data fields exposed, but does not disclose any further behavioral details such as response format, freshness, or failure modes. This is comparable to a straightforward status read where the annotations carry the main burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
