Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('switch') but doesn't mention critical details like whether this requires authentication, if it's destructive (e.g., resets wallet state), or any rate limits. This is a significant gap for a tool that likely changes network settings.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
