Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'kick' implies a destructive action, it doesn't specify whether this is reversible, what permissions are needed, whether notifications are sent, or what happens to the user's data/access. For a potentially sensitive team management operation, this leaves significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
