Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description still adds meaningful behavior beyond them: the result is guaranteed to match the app's own filter and sort for that view, and the view name must be sourced from get_workspace. Return format and pagination behavior are left to the schema/output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
