Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is fully covered by structured data. The description adds nothing on top of that — no note about permanence, whether the alert can be recovered, or required authorization — so it earns no credit beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
