Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare destructiveHint=true and readOnlyHint=false, so the description needed to add context like reversibility, effect on the armature, or required scene state. The description adds nothing beyond a simple restatement of the action, so it does not enhance transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
