Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description bears the full burden of behavioral disclosure. It only states the action and the precondition that the conference is active, but does not mention side effects (e.g., whether participants are removed, recordings stopped, or artifacts deleted), permission requirements, or reversibility.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
