Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the behavioral scope 'finalized,' indicating this tool only lists recording directories that have been finalized. However, it does not disclose output ordering, pagination, or error behavior, but the bar is lower given the strong annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
