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. It does not mention that freezing is typically a destructive action (rendering the track, disabling editing), whether it is reversible, or any required permissions. The vague conditional phrase does not clarify the behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
