Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly indicates a read-style retrieval operation with no destructive intent, but it does not disclose ordering, time windows, retention, or whether returned alerts are consolidated or raw. For a simple getter this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
