Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden. It hints at the content of the response ('which wave is open, what exists today and what doesn't') but says nothing about it being a read-only/side-effect-free operation, whether authentication is needed, or any rate limits. For a zero-annotation tool this is thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
