Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true and destructiveHint=false, so the safety profile is covered structurally; the description adds nothing about what a create does, what the payload must contain, or side effects. The 'viewed or edited' phrasing also leans toward read semantics, which is inconsistent with a create endpoint's non-idempotent write behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
