Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare non-read-only, idempotent, open-world, non-destructive, so safety is covered. The description adds a genuinely non-obvious side effect: resuming also continues the preserved panel recruitment, telling the agent this is more than a status flag flip. It stops short of noting permission requirements or failure modes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
