Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full disclosure burden. It does disclose one behavioral trait — results are scoped to the current user — and the verb 'List' implies a read-only operation. It does not mention authentication prerequisites, pagination, ordering, or response format, but for a zero-parameter list operation the core behavior is adequately conveyed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
