Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare idempotentHint=true, destructiveHint=false, readOnlyHint=false and openWorldHint=false, so the safety profile is largely covered. The description adds only that the collected records are kept 'for later reuse'. It does not say whether toggling off purges previously collected records, whether the change is immediate, or what authorization is required.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
