Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full behavioral burden. It communicates both the state change (reset) and the resulting state (all tools visible). It does not mention persistence or reversibility, but for a zero-parameter tool this is sufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
