Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral disclosure burden. It clearly implies a read-only status operation with no parameters and no side effects. It does not explicitly state 'no side effects', but the wording is sufficient for a no-argument status tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
