Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description does disclose the admin_write permission requirement, which is meaningful behavioral context beyond a bare mutation statement. However, with no annotations, it does not describe side effects, reversibility, return behavior, or whether the optional profile parameter changes behavior. This is adequate but incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
