Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must carry the burden of behavioral disclosure. It only states that the tool gets quotas/usage limits, but does not reveal response format, whether it is read-only (though 'get' implies it), or any other operational behavior. This is insufficient for a no-annotation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
