Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the description doesn't need to restate these. It adds context about the scheduled-assessment scope, but does not disclose other behavioral traits like behavior on missing task_id or whether results are cached. For a read-only tool with strong annotations, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
