Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint=true and destructiveHint=false, covering the main safety profile. The description adds useful context by stating that the response includes version lineage, but it does not disclose rate limits, authorization requirements, or response shape. Overall it supplements the annotations without contradicting them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
