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 'remove' implies a destructive mutation, the description doesn't specify whether this operation is reversible, what happens to frame data, whether it affects animation timing, or any permission requirements. 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.
