Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations and no output schema, the description carries the full burden but partially meets it by enumerating returned fields (purpose, template, entry rules, status, reviews, entry counts) and clarifying the since-filter. It omits ordering, pagination/limits, and any auth or rate-limit context, leaving the behavioral profile incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
