Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint and openWorldHint, but the description adds no additional behavioral context. It does not mention pagination, sorting, or behavior for empty results. With annotations present, the description should at least note that results may be large or require pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
