Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It only says 'get status' without explaining what the status values are, whether there are side effects, or any privacy considerations. The read-only nature is implied but not explicitly stated, and no detail about the response is given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
