Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only says 'check', which implies a read operation, but it does not explicitly state that it does not modify data, nor does it mention authentication requirements, response format, or potential failure modes. For a tool that returns limits, more transparency would be expected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
