Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states it's a 'Get' operation, implying read-only behavior, but doesn't disclose what 'timeline status' includes, whether it requires specific permissions, or how it interacts with the focused presentation state. The description is too minimal for a tool that likely returns structured status information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
