Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description carries the full burden of behavioral disclosure. It usefully reveals that results are bounded to the 200 most recent per side and that the `total` field reflects the true count, which may be much larger—important expectations for callers. It does not mention authentication, errors, or rate limits, but the limit/count disclosure is genuinely informative.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
