Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint: true, idempotentHint: true, and destructiveHint: false, covering the safety profile. The description adds minimal behavioral context beyond 'conflicting/inconsistent', such as the default focus on unresolved conflicts. It does not contradict annotations, but adds limited additional transparency about response behavior or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
