Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds nothing beyond that: it does not say what 'details' are returned, whether the sprint must be active/closed, or any auth requirements, so it contributes no behavioral context of its own.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
