Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It only states 'List', implying a read-only operation, but does not explicitly disclose safety, pagination, response format, or any side effects. For a listing tool this is minimal disclosure, leaving key behavioral traits undocumented.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
