Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states the action is a removal but doesn't disclose behavioral traits: whether this requires admin permissions, if it's reversible, what happens if the user isn't in the group, rate limits, or side effects. The description adds minimal value beyond the obvious 'remove' action, leaving critical behavioral context unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
