Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It merely states 'List lost reasons for deals' with no mention of pagination, sorting, return format, authentication requirements, or any other behavioral traits. This is minimally informative and does not go beyond the literal action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
