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. 'Switch' weakly implies a state change, but the description does not disclose whether the switch affects subsequent operations, whether authentication is required, what happens on an invalid tenant ID, or whether the change persists. For a context-mutating operation, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
