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 only states the basic operation and does not explain what happens when no timer is running (e.g., returns null, empty response, or error), nor any authentication or rate-limit considerations. This is a notable gap for a tool that might be expected to handle a 'no timer' case.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
