Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds context about returning 'milestone progress' (indicating work in progress) and 'final result,' which is useful. However, it does not disclose behavior for invalid tracker codes, rate limits, or authentication requirements, which would be valuable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
