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 adds important auth context ('authenticated user') given login/refresh siblings exist, implying prior authentication is required. However, it omits other behavioral details like pagination, caching, read-only safety confirmation, or return structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
