Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, covering the full safety profile. The description's addition of 'local' corroborates the closed-world hint, but it says nothing about return ordering, pagination, or whether archived tasks require explicit status selection.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
