Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure, but it only states the basic action. It does not mention whether disabling realtime is reversible, whether existing realtime subscribers are affected, whether configuration is removed or paused, or what the response/outcome looks like. This is a notable gap for a state-changing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
