Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true, but the description adds crucial context: the goal is not permanently deleted and can be viewed and restored via list_archive and restore_from_archive. This clarifies the reversibility and reduces the perceived destructiveness, going beyond the raw annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
