Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=true, so the safety profile is covered by structured data — but the description adds nothing at all, not even what a journey is or what cascades when one is deleted (note the sibling cascade_info_retrieve tool). Zero value added beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
