Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of behavioral disclosure. It does disclose the limit default/max and state format, which adds some value. However, it does not explain what happens when state is omitted, any authentication requirements, or other behavioral nuances such as pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
