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 'disable' implies a state-changing operation, the description doesn't specify whether this requires special permissions, whether the action is reversible (though 'enable_account' exists), what happens to associated resources, or any rate limits/constraints. It provides minimal behavioral context beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
