Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false and destructiveHint=true, so the mutating/destructive nature is covered without the description. The description adds little behavioral context beyond this, such as whether existing assessments are overwritten, whether the target must already exist, or what side effects occur. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
