Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations include destructiveHint=false and openWorldHint=false, but no readOnlyHint. The description adds that it's reviewer-only and used by a scheduled cron subcommand, which is useful. However, it doesn't disclose the side effects of running the sweep (e.g., sending emails, marking statuses) or explain the dryRun parameter's behavior, so it doesn't fully compensate for the limited annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
