Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=false, idempotentHint=false, destructiveHint=false and openWorldHint=false, and the description adds nothing on top: it doesn't say whether the switch changes persistent UI state, affects subsequent agent commands, or what happens to the previously focused workspace. It does not contradict the annotations, but it contributes no behavioral context of its own.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
