Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true and idempotentHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: it never mentions the mandatory user-authorization gate (confirm must be true), that retries are not idempotent, or what the write does. With annotations carrying the burden, the description earns only minimal credit for adding no new context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
